Conclusion.214 Appendix A. .215 As the oil tanker M/T Athos I neared Paulsboro, New Jersey, after a journey from Venezuela, an abandoned ship anchor lay hidden on the bottom of the Delaware River squarely within the Athos I’s path and only 900 feet away from its berth. Although dozens of ships had docked since the anchor was deposited in the River, none had reported encountering it. The Athos I struck the anchor, which punctured the ship’s hull and caused approximately 263,000 gallons of crude oil to spill into the River. The cleanup following the casualty was successful, but expensive. This appeal is the result of three interested parties attempting to apportion the monetary liability. The first party (actually two entities consolidated as one for our purposes) includes the Athos Fs owner, Frescati Shipping Company, Ltd., and its manager, Tsakos Shipping & Trading, S.A. (jointly and severally, “Frescati”). Although Frescati states that the spill caused it to pay out $180 million in cleanup costs and ship damages, it was reimbursed for nearly $88 million of that amount by the United States (the “Government”) — the second interested party — pursuant to the Oil Pollution Act of 1990, 33 U.S.C. § 2701 et seq. In order to recoup the unreim-bursed losses, Frescati made claims in contract and tort against the third interested party — a set of affiliates known as CITGO Asphalt Refining Company, CITGO Petroleum Corporation, and CITGO East Coast Oil Corporation (jointly and severally, “CARCO”) — which requested the oil shipped on the Athos I and owned the marine terminal where it was to dock to unload its oil. Specifically, Frescati brought a contract claim for CARCO’s alleged breach of the safe port/safe berth warranty (jointly and severally, “safe berth warranty”) it made to an intermediary— Star Tankers, Inc. — responsible for chartering the Athos I to CARCO’s port, and alleged negligence and negligent misrepresentation against CARCO as the owner of the wharf the Athos I was nearing when it was holed. The Government, as a statutory subrogee that stepped into Frescati’s position for the $88 million it reimbursed to Frescati under the Oil Pollution Act, has limited its claim for reimbursement from CARCO to Freseati’s contractual claim pursuant to a limited settlement agreement. Following a 41-day bench trial, the District Court for the Eastern District of Pennsylvania held that CARCO was not liable for the accident under any of these theories. The Court, however, made no separate findings of fact and conclusions of law as required by Federal Rule of Civil Procedure 52(a)(1). That calls for a remand to set out these mandated matters. However, for the sake of efficiency, we discuss — and, to the extent necessary, make holdings on — the legal issues appealed. *190 In regard to the contractual safe berth warranty, the Court determined that Fres-cati (and the Government as a subrogee) could not recover on their contractual claims. First, Frescati was not a party to the agreement that contained the warranty between CARCO and Star Tankers, and was not an intended beneficiary of that agreement. Furthermore, even if Frescati could claim the protection of the warranty, it was only a promise by CARCO to exercise due diligence and not an unconditional guarantee; moreover, sufficient diligence existed here. In any event, the warranty was excused because CARCO specified the port ahead of the Athos I’s arrival, placing the burden on the Athos I’s captain to accept it as safe or reject it under what is called the “named port exception.” For reasons elaborated below, we disagree with all three of these rulings. Instead, we hold that the Athos I — and by extension, its owner, Frescati — was an implied beneficiary of CARCO’s safe berth warranty. We conclude as well that the safe berth warranty is an express assurance of safety, and that the named port exception to that warranty does not apply to hazards that are unknown to the parties and not reasonably foreseeable. We cannot be sure, however, that this warranty was actually breached, as the District Court made no finding as to the Athos Fs actual draft nor the amount of clearance actually provided. If on remand the District Court rules in favor of Frescati on its contractual warranty claim, its negligence claim becomes unnecessary. If this issue is reached, we do not agree with the District Court’s conclusion that CARCO cannot be liable in negligence because the anchor lay outside the approach to CARCO’s terminal' — -the area in which CARCO had a duty to exercise reasonable care in proving a safe approach. As such, the District Court would need to resolve the appropriate standard of care required, whether CARCO breached that standard, and if so, whether any such breach caused the accident. Conversely, we find no error with the Court’s holding that CARCO’s alleged misrepresentation as to the depth of its berth was geographically (and hence factually) irrelevant to the ultimate accident. In addition, we conclude that the Government has waived reliance on a partial settlement agreement with CARCO that, the Government contends, precludes CARCO from making certain equitable defenses to the Government’s subrogation claims. In this context, we affirm in part, and vacate and remand in part for additional factfinding on the contractual (and possibly negligence) claims. I. Factual and Procedural Background A. The Tanker and Its Charters At the heart of this dispute is the Athos I, a single-hulled oil tanker measuring 748 feet long and more than 105 feet wide. It was owned by Frescati at all relevant times. At the time of the accident, however, the Athos I had been chartered into a tanker pool assembled by Star Tankers, who is not a party to this consolidated action. In order to transport a load of heavy crude oil from Venezuela to its asphalt refinery in Paulsboro, New Jersey, CARCO sub-chartered the Athos I from the Star Tankers pool. In admiralty, these contracts for service are known as “charter parties.” 1 In spe *191 cific regard to Star Tankers, the Athos I was enlisted into the tanker pool in October of 2001 pursuant to a “time charter party.” “Under a time charter, the owner [Frescati] remains responsible for the navigation and operation of the vessel and the charterer [Star Tankers] assumes responsibility for arranging for the employment of the vessel, providing fuel and paying for certain cargo-related expenses.” Terence Coghlin et al., Time Charters ¶ 1.59 (6th ed.2008). The time charter party gave Star Tankers, an intermediary or “middleman,” the right to sub-charter the Athos I although Frescati remained responsible for keeping the vessel staffed and serviceable. In contrast, CARCO’s employment of the Athos I for the specific voyage was pursuant to a “voyage charter party” with Star Tankers. Unlike a time charter party in which a “vessel’s employment is put under the orders of ... charterers” for a period of time, under a voyage charter party the ship is hired “to perform one or more designated voyages in return for the payment of freight.” 2 Julian Cooke et al., Voyage Charters ¶ 1.1 (3d ed.2007). CARCO’s particular voyage charter party, based on a standard industry ASBA-TANKVOY form, contained what are customarily known as “safe port” and “safe berth” warranties (already defined, for convenience, as a “safe berth warranty”). It provided that [t]he vessel ... shall, with all convenient dispatch, proceed as ordered to Loading Port(s) named ..., or so near thereunto as she may safely get (always afloat), ... and being so loaded shall forthwith proceed, as ordered on signing Bills of Lading, direct to the Discharging Port(s), or so near thereunto as she may safely get (always afloat), and deliver said cargo. J.A. at 1222 (Tanker Voyage Charter Party, Part II, ¶ 1). It further directed that “[t]he vessel shall load and discharge at any safe place or wharf, ... which shall be designated and procured by the Charterer [CARCO], provided the Vessel can proceed thereto, lie at, and depart therefrom always safely afloat_” Id. at 1222 (Tanker Voyage Charter Party, Part II, ¶ 9). We note that, in the time charter party between Frescati and Star Tankers, the latter contracted to provide a similar safe berth warranty, but this warranty was qualified whereby Star Tankers obligated itself to exercise “due diligence to ensure that the vessel is only employed between and at safe places....” Id. at 1157 (Time Charter Party ¶ 4). Following the accident, Frescati began arbitration with Star Tankers regarding its claims for damage of the Athos I, but that proceeding has been stayed pending the outcome of this case. Oral Arg. Tr. 4:8-15, Sept. 20, 2012. In preparation for the arrival in Pauls-boro of the Athos I, its master 3 was provided with a copy of CARCO’s Port Manual. This Manual indicated that the allowable maximum draft at the Pauls- *192 boro facility was 38 feet, but that this “may change from time to time and should be verified prior to the vessel’s arrival.” J.A. at 1095 (CITGO Terminal Regulations for Vessels ¶ 2). On November 22, 2004, four days before the Athos I arrived, CARCO reduced this maximum draft to 36 feet. The Athos I was not informed of this modification. B. The Accident On November 26, 2004, the Athos I was nearing its ultimate destination, CARCO’s asphalt refinery in Paulsboro, New Jersey. When the Athos I reached the mouth of the Delaware River, only 80 miles remained of its 1,900-mile journey. Although Captain Iosif Markoutsis was the ship’s master, the seven-hour upriver transit was aided by Delaware River Pilot Captain Howard Teal. At approximately 8:30 p.m., while the Athos I was still navigating up the River channel, Docking Pilot Captain Joseph Bethel boarded the vessel (Captain Bethel was employed by non-party Moran Towing of Pennsylvania). The Docking Pilot relieved the River Pilot at about 8:40 p.m. CARCO’s Paulsboro facility sits on a jetty on the New Jersey side of the Delaware River. Federal Anchorage Number Nine (“the Anchorage” or “Anchorage Number Nine”) separates the River channel from CARCO’s port waters. As pictured in Appendix A to this opinion, the Anchorage’s border runs diagonally to CARCO’s waterfront, ranging between 130 and 670 feet from the face of its ship dock. Across the Anchorage, the River Channel begins less than 2,000 feet from CARCO’s berth, a little more than two-and-a-half lengths of the Athos I. Customarily, a tanker of the Athos I’s size would come up the River, make a starboard (right) 180° turn into the Anchorage, and would then be pushed sideways by tugs (i.e., parallel parked) into CARCO’s pier. The Athos I was following this procedure when, at 9:02 p.m., it suddenly listed to the port (left) side, and oil became visible in the water. It was later determined that an abandoned anchor had punched two holes in the Athos I’s hull, causing (as already noted) roughly 263,000 gallons of crude oil to spill into the River. At the time of the allision, 4 the Athos I was only 900 feet from CARCO’s berth, approximately halfway through the Anchorage. The tide was relatively low at the time of the accident after having reached its lowest point only 50 minutes prior. J.A. at 2102. The anchor was eventually exhumed. Inspection revealed that it weighed roughly nine tons and measured 6'8" long, 7'3" wide, and 4'6" high. J.A. at 2192 (United States Coast Guard Marine Casualty Investigation Report). The Coast Guard further reported that the anchor was ultimately found lying prone with its blade reaching 54 inches above the floor of the River. Id. at 2196. Although the District Court made no finding of fact as to the exact position of the anchor at the time of the allision, it found persuasive the testimony of oceanographer and ocean engineer Dr. Peter Traykovski, who opined that the anchor was lying horizontal at the time of the accident with a height of only 41 inches above the bottom of the River. Traykovski Test., 24:25-25:13, Nov. 4, 2010. The Court also did not make any finding as to the depth of the Anchorage where the anchor lay, though the record before us seems to indicate that the depth was between 40.3 and 41.45 feet deep at low tide. Id. at 49:12-25; J.A. at 2196. *193 The District Court also did not make any finding as to the draft of the Athos I— that is, the distance between the lowest point of the ship and the waterline — but assumed, for purposes of analysis, that it was drawing 36'7" as represented by Fres-cati at the time of the accident. The Court also failed to resolve the anchor’s depth or position, although it noted that there was “persuasive evidence” that the anchor was lying down at the time of the accident. In re Frescati Shipping Co., Ltd., Nos. 05-CV-00305-JF, 08-cv-02898-JF, 2011 WL 1436878, at *7 (E.D.Pa. Apr. 12, 2011). The parties, however, stipulated that the anchor had been in the same approximate location for at least three years because it was detectable from a sonar scan performed by the University of Delaware in 2001 as part of an independent geophysical study.® The owner of the anchor has never been determined, but the Court speculated that the anchor likely was used for dredging operations at the time it was lost. C. The Cost of the Accident Frescati claims that the accident cost it, as the “responsible party” under the Oil Pollution Act, approximately $180 million in clean-up costs and damages to the ship. (The Act was passed in the wake of the Exxon Valdez accident in 1989, and was designed to facilitate oil spill cleanups by requiring “responsible parties” to pay initially for removal costs and damages. See 33 U.S.C. § 2702(a).) Because the Act sets liability limits for cooperative responsible parties, see id. at § 2704(a), an incentive exists for responsible parties to respond quickly and competently in order to limit the extent of their financial exposure. See Unocal Corp. v. United States, 222 F.3d 528, 535 (9th Cir.2000) (“ ‘The purpose of [the Oil Pollution Act] ... was to encourage rapid private party responses.’ ” (quoting In re Metlife Capital Corp., 132 F.3d 818, 822 (1st Cir.1997))). Responsible parties in compliance with the Act may file a claim with the Oil Spill Liability Trust Fund, controlled by the United States Government, for reimbursement of costs beyond the liability limit. 33 U.S.C. § 2708(a)(2). Specifically, Frescati was able to limit its liability for cleanup to $45,474,000, thus allowing it to recover cleanup costs exceeding that amount from the Fund. 6 It was ultimately reimbursed for approximately $88,000,000 of its cleanup costs, and the Fund became subrogated as to that amount under 33 U.S.C. §§ 2712(f) and 2715(a). D. Control of the Waters The casualty here occurred squarely within Anchorage Number Nine. As the term implies, an anchorage ground is “a place where vessels anchor or a place suitable for anchoring.” Webster’s Third New Int’l Dictionary 79 (1971). Section 7 of the Rivers and Harbors Act of 1915 authorizes the establishment of “anchorage grounds for vessels in all harbors, rivers, bays, and other navigable waters of the United States whenever it is manifest ... that the maritime or commercial interests of the United States require such anchorage grounds for safe navigation.... ” 33 U.S.C. § 471. By 1930, a “lack of ade *194 quate anchorage room” was creating a hazard on the Delaware River between navigating vessels and those “awaiting accommodation at the wharves, or awaiting cargo or orders.” H. Doc. No. 71-304, 24 (1930). Anchorage Number Nine, also known as the Mantua Creek Anchorage, was established in 1930. Pub.L. No. 71-520, 46 Stat. 918, 921 (1930). Today it runs for approximately 2.2 miles along the Delaware River channel (see Appendix A) and provides a place for ships to anchor so long as they do not “interfere unreasonably with the passage of other vessels to and from Mantua Creek.” 33 C.F.R. § 110.157(a)(10). Anchorage Number Nine, though only a few hundred feet from CARCO’s pier, is neither controlled nor maintained by CAR-CO. Instead, the federal Government’s Army Corps of Engineers (the “Corps”) conducts hydrographic surveys and dredges as necessary in an attempt to maintain the Anchorage’s depth at 40 feet. The Corps also regulates any construction or excavation within the navigable waters, including the issuance of dredging permits, 33 U.S.C. § 403, and its regulatory jurisdiction “extend[s] laterally to the entire water surface and bed of a navigable wa-terbody, which includes all the land and waters below the ordinary high water mark,” 33 C.F.R. § 329.11. The National Oceanic and Atmospheric Administration conducts surveys on occasion for various federal projects. No Government entity, however, is responsible for preemptively searching all federal waters for obstructions, and the District Court found that the Government does not actually survey the Anchorage for hazards. If, however, the Government is alerted to the presence of a threat, the Corps will remove the obstruction if it is a hazard to navigation and, if not removable, the Coast Guard will chart it. Ultimately, the “[pjrimary responsibility for removal of wrecks or other obstructions lies with the [obstruction’s] owner, lessee, or operator.” 33 C.F.R. § 245.10(b). CARCO maintains a self-described “area of responsibility” directly abutting its Paulsboro terminal, “a roughly triangular-shaped area ... comprising the waters of the berth footprint and the immediate access area next to it where vessels enter and exit the footprint.” CARCO’s Br. at 19. This area, also set out in Appendix A to this opinion, runs essentially the length of CARCO’s facility and extends offshore to the border of the Anchorage. It is based on a permit to dredge for maintenance purposes that was issued by the Corps to CARCO’s predecessor in 1991. The scope of such a permit is derived from the initial request; put another way, it is self-defined subject to approval by the Corps. This area of responsibility is not large enough to rotate the 748 foot-long Athos I. In maintaining its area of responsibility, CARCO retained a consulting engineering firm, S.T. Hudson Engineers, Inc., to perform hydrographic surveys. While CAR-CO had inspected that area for depth, it never specifically searched for debris or other hazards. Hudson interpolated the area’s depth from a grid of pinpointed, single-beam sonar depth soundings at 50-foot intervals. This particular procedure is poor at detecting sunken objects because it is unlikely that any given hazard would fall within the exact spot measured, and if it did, it would not necessarily indicate that there was an object but only the depth of that object as indistinguishable from the bottom of the waterway. Long Test., 78:8-79:5, Nov. 17, 2010; Fish Test, 59:11-18, Sept. 29, 2010. CARCO’s Port Captain William Rankine estimated that approximately 250 ships with a draft of 36'6" or greater either *195 entered or departed CARCO’s port between 1997 and 2005. Rankine Test., 22:25-23:15, Nov. 22, 2010. In specific regard to arriving vessels, from the time the anchor was spotted by the University of Delaware in August 2001 until the Athos I casualty, the record reflects that 61 ships with a draft of 36'6" or greater arrived at CARCO’s facility. J.A. at 1788-94. The record does not reflect at what time these ships docked, and high tide adds approximately six feet of depth to the River. Moreover, Frescati points out that — unlike the Athos I — 21 of these ships would have been required to dock within three hours prior to high-water due to their excessive drafts. 7 Id. at 1622-24. E. The District Court Proceedings In January 2005, Frescati filed in the District Court a Complaint for Exoneration From or Limitation of Liability pursuant to the Shipowner’s Limitation of Liability Act, 46 U.S.C. § 30501 et seq. (formerly 46 App. U.S.C. § 181 et seq.). In that Complaint, Frescati sought a declaration that it was not liable for any losses stemming from the accident or, in the alternative, a limitation of liability to the value of the Athos I and its pending freight. CARCO was among the parties who asserted claims in that action, seeking recovery against Frescati for its lost oil in an amount in excess of $259,217. Frescati then filed a counterclaim against CARCO for all costs incurred beyond those reimbursed by the Fund. In June 2008, the Government filed a separate suit against CARCO seeking compensation on its subrogated right, pursuant to 33 U.S.C. §§ 2712(f) and 2715(a), to the approximately $88 million disbursed by the Fund. In a partial settlement agreement, the Government waived its negligence claims against CARCO in return for the latter’s agreement not to pursue negligence claims against the United States. The Government, believing that CARCO was advancing against it negligence theories in violation of the settlement agreement, moved for partial summary judgment against CARCO’s counterclaim for equitable recoupment. That motion was denied. As noted, these two actions were consolidated, and they were tried over 41 days before Judge Fullam. After trial, the Court issued an 18-page opinion holding that CARCO could not be held responsible under contract or tort for any of the losses stemming from the accident. See In re Frescati, 2011 WL 1436878. On the contractual safe berth warranty, the Court determined that Frescati had no standing for relief, as it was not a third-party beneficiary to the voyage charter party between CARCO and Star Tankers, and that, in any event, CARCO did not breach those warranties because they are not unconditional guarantees but instead “ ‘impose[ ] upon the charterer a duty of due diligence to select a safe berth,’” a duty satisfied here. Id. at *6 (quoting Orduna S.A. v. Zen-Noh Grain Corp., 913 F.2d 1149, 1157 (5th Cir.1990)). The Court further ruled that, even if a stricter warranty applied, the naming of the port in advance precluded recovery under the named port exception, which, as a general matter, protects a charterer when the port is named ahead of arrival and the master proceeds there without protest. *196 The Court also held that CARCO was not negligent in failing to search for or detect the abandoned anchor that lay within the Anchorage. As the Court deemed it outside the approach to CARCO’s berth, detection and notification to others of its presence thus fell beyond CARCO’s obligation to provide a safe entry to that berth. The Court also held that there was no negligent misrepresentation in CAR-CO’s failure to alert the Athos I that — only four days prior to its arrival — the allowable maximum draft at CARCO’s facility had been reduced from 38 feet to 36 feet. It reasoned that this was an internal determination pertaining to the area at the berth and outside the Anchorage, and therefore was “factually irrelevant to the casualty.” Id. at *5. In sum, the District Court concluded that the anchor-dropper rather than any of the named parties was at fault, and rejected all of Frescati’s and the Government’s arguments as to CARCO’s liability. II. Jurisdiction and Standard of Review The District Court had admiralty jurisdiction pursuant to 28 U.S.C. § 1333(1). We have jurisdiction over this appeal under 28 U.S.C. § 1291. Findings of fact made during a bench trial are reviewed for clear error, and will stand unless “ ‘completely devoid of minimum evidentiary support displaying some hue of credibility, or ... bear no rational relationship to the supportive evidentiary data.’ ” In re Nautilus Motor Tanker Co., 85 F.3d 105, 115 (3d Cir.1996) (alteration in original) (quoting Haines v. Liggett Grp. Inc., 975 F.2d 81, 92 (3d Cir.1992)). Following a bench trial, we review de novo a district court’s conclusions of law. McCutcheon v. Am.’s Servicing Co., 560 F.3d 143, 147 (3d Cir.2009) (citation omitted). “[Cjonstruetion of an unambiguous contract is a matter of law and subject to plenary review.” Colliers Lanard & Axilbund v. Lloyds of London, 458 F.3d 231, 236 (3d Cir.2006) (citing U & W Indus. Supply, Inc. v. Martin Marietta Alumina, Inc., 34 F.3d 180, 185 (3d Cir.1994)). Similarly, we exercise “plenary review over the legal question of ‘the nature and extent of the duty of due care....’” Andrews v. United States, 801 F.2d 644, 646 (3d Cir.1986) (quoting Redhead v. United States, 686 F.2d 178, 182 (3d Cir.1982)). III. Rule 52 Federal Rule of Civil Procedure 52(a)(1) provides that “[i]n an action tried on the facts without a jury or with an advisory jury, the court must find the facts specially and state its conclusions of law separately.” Fed.R.Civ.P. 52(a)(1). This is a mandatory requirement. H. Prang Trucking Co., Inc. v. Local Union No. 469, 613 F.2d 1235, 1238 (3d Cir.1980) (citing 9 Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 2574, at 690 (1st ed.1971)); Scalea v. Scalea’s Airport Serv., Inc., 833 F.2d 500, 502 (3d Cir.1987) (per curiam). Typically, a Rule 52 violation occurs when a district court’s inadequate findings render impossible “ ‘a clear understanding of the basis of the decision,’ ” H. Prang Trucking, 613 F.2d at 1238 (quoting Wright & Miller, supra, § 2577, at 697), and those “ ‘findings are obviously necessary to the intelligent and orderly presentation and proper disposition of an appeal,’ ” Bradley v. Pittsburgh Bd. of Educ., 910 F.2d 1172, 1178 (3d Cir.1990) (quoting Mayo v. Lakeland Highlands Canning Co., 309 U.S. 310, 317, 60 S.Ct. 517, 84 L.Ed. 774 (1940)). See also B erguido v. E. Air Lines, Inc., 369 F.2d 874, 877 (3d Cir.1966) (“If a full understanding of the factual issues cannot be gleaned from the District Court’s opinion, we would be obliged to remand for compli- *197 anee with Rule 52(a).”). Although Rule 52 does not require hyper-literal adherence, see Hazeltine Corp. v. Gen. Motors Corp., 131 F.2d 34, 37 (3d Cir.1942), “an appellate court may vacate the judgment and remand the case for findings if the trial court has failed to make findings when they are required,” Giles v. Kearney, 571 F.3d 318, 328 (3d Cir.2009) (citing H. Prang Trucking, 613 F.2d at 1238-39). Instead of presenting his findings in accord with Rule 52, the trial judge here elected to “set forth in narrative fashion [his] findings of fact ... and conclusions of law.” In re Frescati 2011 WL 1436878, at *1. Unfortunately, what followed leaves us unable to discern what were his intended factual findings. Moreover, in arriving at his particular legal conclusions, the trial judge held back making many of the factual findings that would support those conclusions, in effect going from first base to third across the pitcher’s mound. While we do not endorse or require a panoply of extraneous factual findings, the overall dearth of clear factual findings, much less those pertaining to the heart of this matter — such as the draft of the Athos I — falls below what is required by Rule 52. Because we cannot derive a full understanding of the core facts from the District Court’s opinion, this was a violation of Rule 52 and itself a basis for remand. Giles, 571 F.3d at 328. In light of the legal determinations set out below, factual clarification is required in any event. IV. The Contractual Safe Berth Warranty CARCO’s promise to Star Tankers that the Athos I would be directed to a location that “she may safely get (always afloat)” is a provision known in context as either a safe port or safe berth warranty (to repeat again, we use for shorthand “safe berth warranty”). See Cooke et al., supra, ¶ 5.121 (citation omitted). This language triggers two separate protections: a contractual excuse for a master who elects not to venture into an unsafe port, and protection against damages to a ship incurred in an unsafe port to which the warranty applies. See 2 Thomas J. Schoenbaum, Admiralty and Maritime Law § 11-10, at 32-33 (5th ed.2011). In this case, only the second benefit of the safe berth warranty is at issue, as the Athos I was damaged in an allegedly unsafe port. Specifically at issue are the scope and applicability of this warranty, topics we explore below. A. Was Frescati a Third-Party Beneficiary of the Safe Berth Warranty ? “ ‘Before a stranger can avail himself of the exceptional privilege of suing for a breach of an agreement, to which he is not a party, he must at least show that it was intended for his direct benefit.’ ” Robins Dry Dock & Repair Co. v. Flint, 275 U.S. 303, 307, 48 S.Ct. 134, 72 L.Ed. 290 (1927) (quoting German Alliance Ins. Co. v. Home Water Supply Co., 226 U.S. 220, 230, 33 S.Ct. 32, 57 L.Ed. 195 (1912)). As Frescati is not a party to CARCO’s promise to Star Tankers to provide a safe berth, there must be a compelling showing that it was nonetheless an intended beneficiary. The District Court held that this was not the case because the testimony at trial failed to reveal any intent by CARCO to benefit Frescati. The Court, however, failed to inquire whether the contract itself established a third-party beneficiary relationship, a question of law. See Pierce Assocs. v. Nemours Found., 865 F.2d 530, 535 (3d Cir.1988). We conclude that, although Frescati is not a named beneficiary to the safe berth warranty within the charter party between Star Tankers and CAR-CO, the Athos I benefits from this warran *198 ty, and Frescati, as the vessel’s owner, is thus a third-party beneficiary. Maritime contracts “must be construed like any other contracts: by their terms and consistent with the intent of the parties.” Norfolk S. Ry. Co. v. Kirby, 543 U.S. 14, 31, 125 S.Ct. 385, 160 L.Ed.2d 283 (2004). “When a contract is a maritime one, and the dispute is not inherently local, federal law controls the contract interpretation.” Id. at 22-23, 125 S.Ct. 385 (citing Kossick v. United Fruit Co., 365 U.S. 731, 735, 81 S.Ct. 886, 6 L.Ed.2d 56 (1961)). We typically look to the Restatement of Contracts for the federal law on third-party beneficiaries. Doe v. Pennsylvania Bd. of Prob. & Parole, 513 F.3d 95, 106 (3d Cir.2008); see Restatement (Second) of Contracts § 302 (1981). A third-party may be a beneficiary to a contract of others where it is “appropriate to effectf ] the intention of the parties,” and “the circumstances indicate that the promisee intends to give the beneficiary the benefit of the promised performance.” Restatement, supra, § 302(l)(b); see also Cargill Int’l S.A. v. M/T Pavel Dybenko, 991 F.2d 1012, 1019 (2d Cir.1993) (holding that a third-party beneficiary to a charter party “must show that ‘the parties to that contract intended to confer a benefit on [it] when contracting; it is not enough that some benefit incidental to the performance of the contract may accrue to [it]’ ” (alterations in original) (quoting McPheeters v. McGinn, Smith & Co., 953 F.2d 771, 773 (2d Cir.1992))). In 1959, the Supreme Court held that vessels are automatic third-party beneficiaries of warranties of workmanlike service made to their charterers by stevedores who unload vessels at docks. Crumady v. The Joachim Hendrik Fisser, 358 U.S. 423, 428, 79 S.Ct. 445, 3 L.Ed.2d 413 (1959). This is because “[t]he warranty which a stevedore owes when he goes aboard a vessel to perform services is plainly for the benefit of the vessel whether the vessel’s owners are parties to the contract or not.” Id. This natural relationship between the entities was “enough to bring the vessel into the zone of modern law that recognizes rights in third-party beneficiaries.” Id. (citation omitted). A year later, the Supreme Court extended this rule a logical step further in holding that “[t]he owner, no less than the ship, is the beneficiary of the stevedore’s warranty of workmanlike service.” Waterman S.S. Corp. v. Dugan & McNamara, Inc., 364 U.S. 421, 425, 81 S.Ct. 200, 5 L.Ed.2d 169 (1960). Although these two Supreme Court cases aid Frescati’s position, they do so only by analogy. As CARCO points out, the matter before us does not involve an implied warranty for workmanlike service, but an explicit assurance of safety in a document to which Frescati is not a party. The Court of Appeals for the Second Circuit, however, has applied Crumady and Waterman to a set of facts similar to the one before us. In Paragon Oil Co. v. Republic Tankers, S.A., 310 F.2d 169, 171 (2d Cir.1962) (Friendly, J.), a vessel owner (Paragon Oil Co., Inc.) and voyage charterer (Republic Tankers, S.A.) entered into a voyage charter with a safe berth warranty. Republic had executed a contract of affreightment (essentially a sub-voyage charter) with a third-party that contained a safe berth warranty identical to the one it promised in the voyage charter. Id. From this, the Second Circuit concluded that Paragon (the owner) was “the true party in interest” to the safe berth assurance in the contract of affreightment even though it was not explicitly named in the contract between Republic (the voyage charterer) and the third-party. Id. at 175. *199 We agree with the Second Circuit’s reasoning that Crumady and Waterman counsel in favor of Frescati’s third-party beneficiary status. 8 Specifically, we are convinced that a safe berth warranty necessarily benefits the vessel, and thus benefits its owner as a corollary beneficiary. 9 “[T]he circumstances indicate” that the warranty is intended to endow the vessel with “the benefit of the promised performance.” Restatement, supra, § 302(l)(b). Because the warranty explicitly covers the safety of the vessel, it would be nonsensical to deprive the'vessel’s owner the benefits of this promise, as the owner is ultimately the one most interested in the vessel’s status and is obligated to maintain its condition. 10 Moreover, it would work an odd windfall if Star Tankers were allowed to collect on CARCO’s safe berth warranty but not be required to pass on those remedial dollars to the ship’s ultimate owner. That illogical result could occur where the owner (Fres-cati) received no safe berth warranty from the time charterer (Star Tankers), or where — as in the case before us — Frescati received a less comprehensive warranty from Star Tankers than Star Tankers received from the voyage charterer (CAR-CO). 11 This would theoretically allow Star Tankers to collect for damages to the ship that were actually paid by Frescati. While we are mindful of the parties’ ability to contract differently, there is no" indication that Star Tankers bargained for the potential of such an unearned windfall — profiting from the mishaps of the vessels within its tanker pool when it did not pay for the repair of those mishaps. Instead, requiring warranties from voyage charterers like CARCO is a way to insure against claims asserted by vessel owners. Per this path, the promise made to protect a vessel flows through the intermediary party(ies) to the ultimate party who bore the pain of an unsafe port, here the vessel’s owner. We discount CARCO’s suggestion that it was unaware of Frescati’s status as the true owner of the Athos I. CARCO had completed an internal vetting of the Athos I in October of 2004 that identified Fresca-ti as its owner. J.A. at 1318 (Citgo Yet-ting Report). Regardless, even if the ultimate owner had been undisclosed, CARCO *200 expressly warranted to provide a safe berth, which is a promise made “plainly for the benefit of the vessel.” Crumady, 358 U.S. at 428, 79 S.Ct. 445. Thus we see no reason why the Athos I’s owner would be any less entitled to rely on this warranty, whether it was identified or not. Frescati, as the owner of the Athos I, may therefore rely on CARCO’s safe berth warranty as a third-party beneficiary. B. The Scope of the Safe Berth Warranty That Frescati may benefit from CARCO’s safe port/safe berth warranty requires that we delineate its comprehensiveness, a question of first impression in our Circuit. Though the District Court did not need to reach this legal issue after determining that Frescati was not a third-party beneficiary, it nonetheless concluded — as an alternate holding — that the safe berth warranty was not breached because “CARCO fulfilled its duty of due diligence....” In re Frescati, 2011 WL 1436878, at *6. We part from this holding, as we believe the Court incorrectly relied on Orduna S.A v. Zen-Noh Grain Corp., 913 F.2d 1149, 1157 (5th Cir.1990), which held that the safe berth provision was not a full warranty but required only due diligence. A port is deemed safe where “the particular chartered vessel can proceed to it, use it, and depart from it without, in the absence of abnormal weather or other occurrences, being exposed to dangers which cannot be avoided by good navigation and seamanship.” Cooke et al., supra, ¶ 5.137; Leeds Shipping v. Societe Francaise Bunge (The Eastern City), [1958] 2 Lloyd’s Rep. 127, 131 (same). Whether a port is safe refers to the particular ship at issue, Cooke et al., supra, ¶ 5.68, and goes beyond “the immediate area of the port itself’ to the “adjacent areas the vessel must traverse to either enter or leave,” Coghlin et al., supra, ¶ 10.124. In other words, a port is unsafe — and in violation of the safe berth warranty — where the named ship cannot reach it without harm (absent abnormal conditions or those not avoidable by adequate navigation and seamanship). 12 This formulation is deeply rooted. In 1888, the Supreme Court held charterers liable for breach of a safe berth warranty in insisting that a ship sail to Aalborg, Denmark, a port that was impossible for the particular ship to reach due to a sand bar and the absence of any reasonably safe place to anchor or discharge. The Gazelle, 128 U.S. 474, 485-86, 9 S.Ct. 139, 32 L.Ed. 496 (1888). In a similar fashion, the Supreme Court held in 1902 that charterers failed to provide a safe dock where the ship in question could not reach it without damage. Mencke v. Cargo of Java Sugar, 187 U.S. 248, 253, 23 S.Ct. 86, 47 L.Ed. 163 (1902). Specifically, the charterers were aware that the ship’s mast was too tall to clear the Brooklyn Bridge when they designated a discharge dock upriver from the Bridge. Id. at 250, 23 S.Ct. 86. The Court concluded that this was a warranty violation by analogizing the overhead obstacle to a submerged one: “A ship could not be said to be afloat, whether the obstacle encountered was a shoal or bar in the port over which she could not proceed, or a bridge under or through which she could not pass, nor could she be said to have safely reached a dock if required to mutilate her hull or her permanent masts.” Id. at 253, 23 S.Ct. 86; see also Carbon Slate Co. v. Ennis, 114 F. 260, 261 (3d Cir.1902) (concluding that safe berth warranty was violated where the ship “was directed to load at a berth where a full cargo, if taken aboard, would have made it impossible for her, at any stage of water or at any time, to pass out over the harbor bar”). *201 The Court of Appeals for the Second Circuit has long held that promising a safe berth effects an “express assurance” that the berth will be as represented. Cities Serv. Transp. Co. v. Gulf Ref. Co., 79 F.2d 521, 521 (2d Cir.1935) (per curiam), recognized this principle in holding that a master was not liable for damages incurred in reliance on a charter party’s safe berth warranty at a particular dock. In Park S.S. Co. v. Cities Serv. Oil Co., 188 F.2d 804, 806 (2d Cir.1951) (Swan, J.), the same Court elaborated that the purpose of the warranty was to memorialize the relationship between the contracting entities: “the charterer bargains for the privilege of selecting the precise place for discharge and the ship surrenders that privilege in return for the charterer’s acceptance of the risk of its choice.” Paragon continued this tradition in contrasting the duty of a wharfinger (an admiralty term for an “owner or occupier of a wharf,” Black’s Law Dictionary 1738 (9th ed.2009)) — to exercise reasonable diligence in keeping its berth safe for incoming vessels — with that of a charterer who is contractually bound to provide “not only a place which he believes to be safe, but a place where the chartered vessel can discharge ‘always afloat.’ ” 810 F.2d at 178 (citation and internal quotation marks omitted). See also Venore Transp. Co. v. Oswego Shipping Corp. 498 F.2d 469, 472 (2d Cir.1974) (citing Park S.S. Co., 188 F.2d at 804) (sub-charterer had a non-delegable “obligation to provide a completely safe berth,” which was breached when it permitted the ship to dock at a berth that it knew was unsafe). Thus, prior to the Fifth Circuit’s decision in Orduna, “the law concerning safe ports had a rather secure berth in maritime law and it was well settled that a safe port clause in a charter constituted a warranty given by a charterer to an owner.” Cooke et al., supra, ¶ 5.124. Orduna created quite a splash in veering from the view that a charterer warrants a ship’s safety, and established instead for the Fifth Circuit that a safe berth warranty merely “imposes upon the charterer a duty of due diligence to select a safe berth.” 913 F.2d at 1157. While Orduna acknowledged the Second Circuit’s contrary perspective, it dismissed that interpretation in deference to critical commentators, namely Professors Grant Gilmore and Charles L. Black. Id. at 1156 (citing Grant Gilmore & Charles L. Black, The Law of Admiralty § 4-4, at 204-06 (2d ed.1975)). We do not find their criticism so compelling. 13 Orduna concluded that “no legitimate legal or social policy is furthered by making the charterer warrant the safety of the berth it selects.” Id. at 1157. Primarily, the Court reasoned that it is more sensible to impose fault on the “master on the scene” rather than a far away merchant charterer. 14 Id. at 1156 (citing Gilmore & *202 Black, supra, § 4-4, at 204-06). The appeal of this construction here is illusory. While an owner is liable for its master’s superseding negligence, see Cooke et al., supra, ¶ 5.151, we see no policy reason why a master on board a ship would normally be in any better position to appraise a port’s more subtle dangers than the party who actually selected that port. The “commercial reality [is] that it is the charterer rather than the owner who is selecting the port or berth,” id. ¶ 5.126, and the charterer is more likely to have at least some familiarity with the port it selected. After all, charterers do not select ports without good reason (and, in the case before us, CARCO was directly on the scene, as it had selected its own berth). Messrs. Gilmore and Black (famous in other areas of law-Gilmore on commercial law, including secured transactions, and Black on constitutional law) acknowledged that their rationale is undermined in those instances where a charterer has more knowledge of a danger than the master (although they explain that these situations could be remedied through tort liability 15 ). We disagree. To any extent a charterer, however distant, bargains to send a ship to a particular port and warrants that it shall be safe there, we see no basis to upset this contractual arrangement. We are persuaded that the Second Circuit’s longstanding formulation of the safe berth clause is the one we should follow. 16 See 2 Schoenbaum, supra, § 11-10, at 32-33 (citing The Gazelle, 128 U.S. 474, 9 S.Ct. 139, 32 L.Ed. 496 (1888)) (“[I]f the ship reasonably complies with the order and proceeds to port, the charterer is liable for any damage sustained.”); Stewart C. Boyd et al., Scrutton on Charter Parties and Bills of Lading, Section IX, art. 69, at 127 (20th ed.1996) (same); 2A Michael F. Sturley, Benedict on Admiralty § 175, at 17-25 (7th ed.2012) (same); Coghlin et al., supra, ¶ 10.110 (same). But see Gilmore & Black, supra, § 4-4, at 204-06. Beyond the near consensus of these authorities, we are also convinced that an “express assurance” warranty is most consistent with industry custom. See Park S.S., 188 F.2d at 806; Cities Serv., 79 F.2d at 521. Vessel charters are formalized via “highly standardized forms,” 2 Schoenb-aum, supra, § 11-1, at 4-5 (citation omit *203 ted). That some forms explicitly adopt a due diligence standard 17 suggests that the understood default is to impose liability on the charterer without regard to the care taken. See Coghlin et al., swpra, ¶¶ 10.52, 10.54. Reading these warranties as dappled with due diligence would make contractual language explicitly adopting a due diligence metric pointless, and we disfavor contract interpretation “that ‘render[s] at least one clause superfluous or meaningless.’ ” Sloan & Co. v. Liberty Mut. Ins. Co., 653 F.3d 175, 181 (3d Cir.2011) (alteration in original) (quoting Garza v. Marine Transp. Lines, Inc., 861 F.2d 23, 27 (2d Cir.1988)). Moreover, the “always afloat” language plainly suggests an express assurance. To the extent the Fifth Circuit in Orduna deviated from this well-established standard, we are not persuaded by its reasoning and decline to follow the course it charted. 18 Hence we conclude that the safe berth warranty is an express assurance made without regard to the amount of diligence taken by the charterer. C. Was the Safe Berth Warranty Breached ? As explained, a berth is deemed safe when a ship may “proceed to it, use it, and depart from it without ... being exposed to dangers.” Coghlin et al., supra, ¶ 10.123. As noted above, see supra note 12, CARCO conceded at oral argument that the safe berth warranty — if applicable — “would include the area in and around Paulsboro,” including the Anchorage, and we therefore need not delineate the geographic sweep of this warranty. Thus having determined that Frescati was a beneficiary of CARCO’s safe berth warranty and that this warranty applies irrespective of a charterer’s diligence, we proceed to whether the warranty was actually breached by the anchor’s presence. Specifically, we need to determine whether the anchor rendered CARCO’s port unsafe for a ship of the Athos I’s agreed-upon dimensions and draft. That the Athos I was injured by the anchor does not automatically indicate that the warranty was breached. CARCO’s safe berth warranty was not a blank check; it did not warrant that any ship would be safe at its port, but instead assured that the port would be safe for the Athos I. Boyd et al., supra, Section IX, art. 69, at 129-30 (citations omitted) (“Whether a port is a ‘safe port’ is in each case a question of fact and degree and must be determined with reference to the particular ship concerned.... ”); In re Lloyd’s Leasing Ltd., 764 F.Supp. 1114, 1135 (S.D.Tex.1990) (“The safety of a port is to be determined with reference to the vessel and the circumstances surrounding that vessel’s use of the port.”). In this regard, the District Court correctly framed the ultimate issue as whether it was possible for a ship of the Athos I’s purported dimensions to reach CARCO’s berth safely. In re Frescati 2011 WL 1436878, at *6. The Court, however, neglected to make the necessary factual findings to resolve whether the warranty was actually breached. Instead, it concluded “that the port and berth were generally safe” due to “the volume of commercial traffic that passed without incident,” notwithstanding that it *204 was impossible to know how many of those ships had actually passed over the anchor. Id. That similar ships had successfully berthed at the port is irrelevant to whether the warranty was actually breached in this ease, as “[a] dangerous place may often be stopped at or passed over in safety.” The Gazelle, 128 U.S. at 485, 9 S.Ct. 139. Instead, the Court should have evaluated whether the port was safe based on the facts particular to the Athos I and its arrival. From what we can glean from the record, it appears that CARCO warranted a safe berth with the understanding that the Athos I would be drawing as much as 37-feet of water upon its arrival. The Voyage Instructions indicate that the vessel would be filled with a quantity of crude oil “always ... consistent with a 37 [foot] or less [fresh water] sailing draft at loadport,” J.A. at 1242, and Captain Markoutsis confirmed this directive, Markoutsis Test. 199:5-9, Oct. 13, 2010. He testified, moreover, that he was “afraid of that draft,” and opted to load the ship to only 36'6". 19 Id. at 200:7-25. This latter figure was confirmed by CARCO Port Captain William Rankine, who testified that the Athos I reported that it was drawing 36'6", Rankine Test. 41:5-12, Nov. 22, 2010, and also by Steamship Agent Stephen Carroll, Carroll Test. 63:2^1, Oct. 7, 2010. In any event, the warranty made by CARCO appears to have covered the Athos I up to a draft of 37 feet. 20 Yet, as noted throughout this opinion, the District Court made no finding on the vessel’s actual draft at the time of the accident. This needs to be corrected on remand. 21 If it is found that the Athos I was drawing 37 feet or less and absent a determination of bad navigation or seamanship, 22 that finding would indicate that the warranty had been breached because the ship *205 sustained damage. What, if anything, under the water may have caused that margin to be diminished is therefore immaterial. It could have been the remnants of a shipwreck, a range of rocks, a jutting reef, or a shoal. In this case, it happened to be an abandoned anchor that protruded into the Athos I’s hull. And by its safe berth warranty, CARCO assumes liability for that damage. If the draft at the time of the accident cannot be determined, or if the Athos I is found to have been drawing more than 37 feet, it will be necessary to ascertain the amount of clearance that existed above the anchor to conclude whether the promised 37 feet of water depth was actually provided. 23 Because it appears that CARCO assured a safe berth for a ship drawing 37 feet or less, our concern is whether 37 feet of clearance existed at the time of the accident. D. The Named Port Exception CARCO exposes one additional limitation to the broad protection generally afforded by the safe berth warranty — the named port exception. In essence, “[w]hen a charter names a port and the master proceeds there without protest, the owner accepts the port as a safe port, and is bound to the conditions that exist there.” Bunge Corp. v. M/V Furness Bridge, 558 F.2d 790, 802 (5th Cir.1977) (internal quotation marks omitted) (quoting Pan Cargo Shipping Corp. v. United States, 234 F.Supp. 623, 638 (S.D.N.Y.1964), aff'd, 373 F.2d 525 (2d Cir.1967)). The purpose of the exception is to shift liability to the owner once a ship’s master has had ample opportunity to discover a port’s hazards. 24 As such, the exception may apply in instances in which a master — without lodging any objection — is charged “with full knowledge of local conditions which make it unsafe for that particular voyage.” Coghlin et al., supra, ¶ 10.158; see also Cooke et al., supra, ¶ 5.130 (“[T]he master’s conduct in entering a port he considers unsafe without raising a protest may result in a waiver of the safe port warranty”). This formulation is essentially an application of the above-mentioned rule that negligent seamanship will nullify the safe port warranty: once a particular risk becomes known, it is then the master’s responsibility to avoid it through compe *206 tent seamanship or to declare the port unsafe. This application of the exception does not apply to the case before us, however, as there is no suggestion that anyone — much less the master of the Athos I — had any inkling as to the anchor’s existence in the River. Instead, and more pertinent to the Athos I, the exception is also triggered when a particular port is named in the charter party. See Cooke et al., supra, ¶ 5.130 (“If the charter names the ports or berths the vessel will call at, the general rule is that the ports or berths will have been accepted by the owner as safe, such that the safe port/safe berth warranty is deemed to have been waived.”); Coghlin et al., supra, ¶ 10.164 (same) (citations omitted). This particular application of the exception is very broad and would seem poised to swallow the rule, but frequently the voyage charter will specify a range of ports, and thus the “safe [berth] warranty continues to play a role in voyage charters.” Cooke et al., supra, ¶ 5.123. In fact, this is such a case; the voyage charterer (CARCO) did not specifically name the discharge port in the voyage charter party, but instead directed that the Athos I would transit to one or two safe ports located somewhere on the United States Atlantic Coast, Gulf Coast, or the Caribbean Sea. J.A. at 1225 (Tanker Voyage Charter Party, Special Provision 2). CARCO nonetheless maintains that this exception applies even where the port location is not specifically named in the charter so long as some advance notice of the designated port is given. It is unclear how much notice would be required under CARCO’s theory of the exception, although CARCO argues that it applies here because there is evidence that the master knew approximately two weeks before the accident that the Athos I would be headed to Paulsboro, New Jersey. We need not address this issue of advance notice because we conclude that the hazard of the submerged anchor was not the sort contemplated by the exception. As explained above, the purpose of the named port exception is to “relieve[] the charterer of liability for damage arising from conditions at that port so long as those conditions were reasonably foreseeable.” Duferco Int’l Steel Trading v. T. Klaveness Shipping A/S, 333 F.3d 383, 387 (2d Cir.2003) (emphasis added) (citations omitted). Without at least an opportunity to discover a particular port’s specific pitfalls, the identity of the port would be irrelevant. This would defeat the purpose of naming the port, which is to excuse charterers for the results of hazardous conditions known to the master, not to exonerate them completely from all resulting liability. In sum, here the particular hazard — the submerged anchor — was unknown to the parties. As the naming of CARCO’s port ahead of time did not provide the Athos I with an opportunity to accept this unknown hazard, the exception does not come into play. 25 V. The Tort Claims Should its claim regarding CARCO’s contractual liability not succeed, Frescati *207 argues in the alternative that CARCO is liable as the owner of the terminal receiving the Athos I under two tort theories: negligence and negligent misrepresentation. The District Court held both theories inapplicable.' Although we agree that the negligent misrepresentation claim fails on these facts, we disagree with the Court’s 'conclusion that Frescati’s negligence claim is necessarily precluded. A. Negligence Negligence in admiralty law is essentially coextensive with its common law counterpart, requiring: (1) “[t]he existence of a duty required by law which obliges the person to conform to a certain standard of conduct”; (2) “[a] breach of that duty by engaging in conduct that falls below the applicable standard or norm”; (3) a resulting loss or injury to the plaintiff; and (4) “[a] reasonably close causal connection between the offending conduct and the resulting injury.” 1 Schoenbaum, supra, §§ 5-2, at 252; Pearce v. United States, 261 F.3d 643, 647 (6th Cir.2001) (citation omitted) (same). Because this accident resulted in a clear loss, we address the existence of a duty, the potential breach of that duty, and causation. As discussed above, the wharfinger in this case — CARCO—contracted to provide the Athos I a safe berth. In the tort context, however, a wharfinger is not a guarantor of a visiting ship’s safety, but is “ ‘bound to use reasonable diligence in ascertaining whether the berths themselves and the approaches to them are in an ordinary condition of safety for vessels coming to and lying at the wharf.’ ” Smith v. Burnett, 173 U.S. 430, 436, 19 S.Ct. 442, 43 L.Ed. 756 (1899) (quoting, with approval, The Calliope, [1891] A.C. 11 (H.L.) 23 (appeal taken from Eng.)). This is not an unconstrained mandate to “ensure safe surroundings or warn of hazards merely in the vicinity.” In re Nautilus, 85 F.3d at 116 (citing Trade Banner Line, Inc. v. Caribbean S.S. Co., S.A., 521 F.2d 229, 230 (5th Cir.1975)). Instead, a visiting ship may only expect that the owner of a wharf has afforded it a safe approach. Id. (citations omitted). In being invited to. dock at a particular port, “a vessel should be able to enter, use and exit a wharfin-ger’s dock facilities without being exposed to dangers that cannot be avoided by reasonably prudent navigation and seamanship.” Id. While CARCO has a duty to maintain a safe approach to its terminal, we must determine the geographic scope of that duty. i. The Scope of the Approach The geographic scope of a safe approach has been largely unaddressed by the courts. Frescati argues that the scope should be inferred as a matter of custom and practice, and CARCO counters that the approach should be a function of the wharfinger’s exertion of control. The District Court, in attempting to adopt a workable method of analysis, was chiefly concerned about CARCO’s lack of control in the Anchorage and the absence of a limiting principle if it were to define the approach as the waters that a ship “naturally would traverse.” In re Frescati, 2011 WL 1436878, at *4. Accordingly, it opted to limit the approach to “the area ‘immediately adjacent’ to the berth or within ‘immediate access’ to the berth.” Id. (quoting Western Bulk Carriers v. United States, No. S-97-2423, 1999 WL 1427719, 1999 U.S. Dist. LEXIS 22371, at *20-21 (E.D.Cal. Sept. 14, 1999)). Such immediacy, we believe, sets too constricted a path to the berth. Instead, we hold that an approach should be understood by its ordi- , nary terms, and that its scope is derived *208 from custom and practice at the particular port in question. Bouchard Transportation Co. v. Tug Gillen Brothers, 389 F.Supp. 77 (S.D.N.Y. 1975), is helpful in defining the geographic scope of an approach. It partially concerned a claim by a barge owner against the terminal owner for negligence in failing to maintain a safe approach and to warn of an unsafe condition. Id. at 79. The District Court there found that the approach began when the barge — traveling mid-channel up the Hudson River — altered its heading such that it was on a straight course to the terminal, which was the normal practice for ships docking there. Id. at 80. While executing this procedure, the barge grounded, its hull was punctured, and oil was lost. 26 Id. at 80-81. Bouchard concluded that the terminal owner “was negligent in failing to maintain the approach to its terminal, in particular that area outside the river channel and within its dominion and control, normally utilized as the southerly approach to its ship dock, free of obstruction and safe for vessels approaching said terminal.” 27 Id. at 81. Less instructive, but still worth exploring, .is P. Dougherty Co. v. Bader Coal Co., 244 F. 267 (D.Mass.1917). There, an invitation to use a particular dock in a charter party was construed to “extendf] to the approaches to the dock, and to the water which would naturally be traversed or used by a vessel discharging there.” Id. at 270 (citing Hartford & N.Y. Transp. Co. v. Hughes, 125 F. 981 (S.D.N.Y.1903)). Although P. Dougherty is of limited usefulness on its facts (the Court was interpreting the parties’ express agreement to use the dock), its conclusion that the wharfin-ger’s obligation covered “individual approaches,” distinguished from “the common channel,” is nonetheless helpful. Id. More recently, MS Tabea Schijfahrtsge-sellschaft mbH & Co. KG v. Bd. of Com’rs of the Port of New Orleans, No. 08-3909, 2010 WL 3923168, at *2 (E.D.La. Sept. 29, 2010), aff'd, 434 Fed.Appx. 337 (5th Cir. 2011), similarly defined the approach as “the area through which vessels travel in order to move from the main channel of the river to the berth.” See also McCaldin v. Parke, 142 N.Y. 564, 37 N.E. 622, 624 (1894) (determining that a cluster of rocks “not in any channel which had to be used to approach the wharf,” but potentially “in that part of the river used for general navigation,” was not within the approach). In light of these cases, we are persuaded by the suggestion in the maritime industry associations’ amici brief that an approach should be afforded its plain meaning. See Mar. Indus. Ass’ns Amici Br. at 20. As a noun, “approach” is defined as “a drawing near in space or time,” and “a way, pas *209 sage, or avenue by which a place or a building can be approached.” Webster’s Third New Int’l Dictionary 106 (1971). This suggestion is persuasively illustrated by amici’s reference to an airplane on final approach or a golf ball approaching the green. Both examples capture the intuitive meaning of the term as the beginning of a final, linear path to a fixed point. In fact, Webster’s specifically incorporates those examples into its definition, listing “a golfing stroke from the fairway for the green,” “the steps and motion of a bowler before he delivers the ball,” and the “descent of an airplane toward a landing strip.” Id. What is an approach should be given its same plain meaning in the maritime context; when a ship transitions from its general voyage to a final, direct path to its destination, it is on an approach. This is the most logical construction, and it comports with those cases suggesting that an approach should be gleaned from actual practice. See, e.g., Bouchard, 389 F.Supp. at 80-81 (concluding that the approach began where vessels departed the channel on a direct course to the receiving dock and defined it pursuant to the area “normally utilized”). It also reflects the definition used in the maritime industry. For example, The Mariner’s Handbook defines “approaches” as “[t]he waterways that give access or passage to harbours, channels, and similar areas.” J.A. Petty, The Mariner’s Handbook 226 (8th ed.2004). Further, in most cases it will not result in a line-drawing problem, a concern raised by CARCO and shared by the District Court. Entire rivers, bays, and oceans will not be transformed into approaches. Instead, in most instances the approach will begin where the ship makes its last significant turn from the channel toward its appointed destination following the usual path of ships docking at that terminal. This analysis will necessarily vary on the characteristics of a particular port, and there will be close and difficult cases. Accordingly, we believe it may be useful to analogize the final approach of a vessel to a port to that of a driveway leading to a home from the public road. 28 It is the last segment of the voyage leading directly to the host’s door. Marine navigation is further complicated in that ships sometimes have the luxury of approaching through a variety of different courses across open water. Yet, so long as a ship is not approaching in an illogical, unreasonable, or disallowed manner, it will be deemed within its approach when it is within this final phase of its journey. ii. Was the Athos I Within the Approach to CARCO’s Terminal When the Accident Occurred ? Fortunately, the case before us is not one of the difficult ones, for the facts indicate that the Athos I was within the approach when it struck the anchor. First, the vessel was following the usual path for ships of its size docking at CAR-CO’s terminal, having turned away from *210 the channel at the usual point and was being pushed by two tugboats in a straight path toward CARCO’s pier. Moreover, there were other indicators that the Athos I had ceased navigating generally and was within the final phase of its travel, namely that it was rotated sideways and, as noted, assisted by tugs. While not dispositive factors, these trappings indicate that the Athos I was no longer voyaging, but was configured solely for docking. To the extent CARCO argues that the sphere of control exercised by it should be used to limit the scope of its duty, 29 we hold that a failure to exercise control over an area is not conclusive in this analysis. The appeal of The Moorcock long-ago dispatched this argument. 30 [1889] 14 P.D. 64 (Eng.). The steamship Moorcock was invited to be discharged and loaded at a particular wharf where it would be moored alongside the wharfingers’ jetty. Id. at 64. Although the ship was expected to rest on the bottom of the River Thames at low tide, the particular section of riverbed was not actually under the wharfingers’ control. Id. at 69. Even so, the Court explained that it “d[id] not follow that [the wharfingers] are relieved from all responsibility. They are on the spot.” Id. at 70. It continued: No one can tell whether reasonable safety has been secured except themselves, and I think if they let out their jetty for use they at all events imply that they have taken reasonable care to see whether the berth, which is the essential part of the use of the jetty, is safe, and if it is not safe, and if they have not taken such reasonable care, it is their duty to warn persons with whom they have dealings that they have not done so. Id.; see also The Cornell No. 20, 8 F.Supp. 431, 438 (S.D.N.Y.1934) (“However, it is clear that the obligation of the wharfinger is not limited to the area of the land under water actually owned by it.... It implied-edly [sic] represents to the master of a vessel who is induced to bring his vessel to its wharf that the berth and immediate access to it are reasonably safe for the vessel.”). In addition, insofar as the sphere of responsibility exercised by CARCO is a voluntary assumption of duty, it cannot be relied on to restrict the scope of a port owner’s duty as a matter of law. Limiting a wharfinger’s responsibility to areas in which it has affirmatively assumed responsibility would allow it to define the scope of its own liability regardless of the port’s actual approach. Such a construction plays poorly against a policy that places logic and common sense over self-serving limitations of liability in the tort context. Moreover, we are not convinced that CAR- *211 CO was actually precluded from extending its area of responsibility into the Anchorage. The record reflects that permission to it was not required for sonar scans, for example, and the record lacks an indication that CARCO could not have obtained a dredging permit for the Anchorage if it desired to do so. We conclude that the Athos I was well within the approach to CARCO’s terminal when the casualty occurred, and that it therefore had a duty to exercise reasonable diligence in providing the Athos I with a safe approach. iii. Potential Breach of Duty to Maintain a Safe Approach Having determined that the Athos I was within its approach when it was damaged and that CARCO therefore owed it a safe approach, did CARCO satisfy that duty by exercising the standard of care required of a reasonable wharfinger under the circumstances? Although “the nature and extent of the duty of due care is a question of law,” factual issues predominate here as they do in most negligence litigation. Redhead v. United States, 686 F.2d 178, 182 (3d Cir.1982). Thus, we review findings of negligence as factual findings for clear error. See In re Moran Towing Corp., 497 F.3d 375, 377-78 (3d Cir.2007); Andrews v. United States, 801 F.2d 644, 646 (3d Cir.1986). As noted, there were no findings. Negligence exists where there was a “fail[ure] to exercise that caution and diligence which the circumstances demanded, and which prudent men ordinarily exercise.” Grand Trunk R.R. v. Richardson, 91 U.S. 454, 469, 23 L.Ed. 356 (1875). The admiralty context is no different, requiring “reasonable care under the particular circumstances.” 1 Schoenbaum, supra, § 5-2, at 253 (citation omitted); see also Smith, 173 U.S. at 436, 19 S.Ct. 442 (remarking that wharfingers are “bound to use reasonable diligence” (citation and quotation marks omitted)). In admiralty, the particular duty required under any given circumstance can be gleaned from statute, custom, or “the demands of reasonableness and prudence.” 1 Schoenbaum, supra, § 5-2, at 253 (citing Pennsylvania R.R. v. S.S. Marie Leonhardt, 202 F.Supp. 368, 375 (E.D.Pa.1962), aff'd, 320 F.2d 262 (3d Cir.1963)). Of course, “the degree of care which the law requires in order to guard against injury to others varies greatly according to the circumstances of the case.” Richardson, 91 U.S. at 469-70. On the facts before us, we are insufficiently informed to delineate the exact standard of care required by CARCO, 31 let *212 alone whether there was a breach of that standard (a.k.a. duty). That task rests with the District Court on remand should it need to reach the negligence claim. iv. Causation On remand, the District Court will also need to determine whether the failure, if any, to meet the standard of care proximately caused the accident. “Questions of causation in admiralty are questions of fact.” Stolt Achievement, Ltd. v. Dredge B.E. LINDHOLM, 447 F.3d 360, 367 (5th Cir.2006); see also In re Nautilus, 85 F.3d at 116 (reviewing, in admiralty, a district court’s determination as to causation for clear error). The purpose of requiring proximate cause is “to limit the defendant’s liability to the kinds of harms he risked by his negligent conduct.” 1 Dan B. Dobbs et al., The Law of Torts § 198, at 681 (2d ed.2011) (citations omitted). Proximate cause is something of a misnomer in that it “is not about causation at all but about the appropriate scope of legal responsibility.” Id. at 682. Instead, “proximate cause holds that a negligent defendant is liable for all the general kinds of harms he fore-seeably risked by his negligent conduct and to the class of persons he put at risk by that conduct.” Id. at 682-83; 1 Schoenbaum, supra, § 5-3, at 260-61 (“[T]he injury or damage must be a reasonably probable consequence of the defendant’s act or omission.”). CARCO argues that proximate cause is lacking on these facts because the presence of an anchor in the anchorage was not foreseeable, especially by virtue of other ships arriving unharmed in the past. Once again, we decline to resolve this issue on the record before us. CARCO further argues that proximate cause is lacking on the basis that the anchor-dropper was the actual cause of the accident. It is clear, however, “ ‘that there may be more than one proximate cause of an injury.’ ” Serbin v. Bora Corp., 96 F.3d 66, 75 (3d Cir.1996) (quoting Davis v. Portline Transportes Mar. Internacional, 16 F.3d 532, 544 (3d Cir.1994)). More crucially, the issue is whether the accident would have been prevented had CARCO exercised its duty to act as a prudent wharfinger within the approach. At a minimum, this requires “that the injury would not have occurred without the defendant’s negligent act.” 1 Schoenb-aum, supra, § 5-3, at 259. Here, the causation inquiry turns on whether prudent behavior — had it been exercised, a factual inquiry — would have prevented the injury. See Dobbs et al., supra, § 184, at 620. In light of CARCO’s invitation that the Athos I arrive drawing 37 feet or less, see supra Part IV.C, it may be that the anchor lay sufficiently deep such that it would not have been detected even if CARCO had acted as a prudent wharfinger. Conversely, it could be the case that — even if the 37 feet of contractual clearance were provided — CARCO’s duty as a wharfinger required something more. Should this be put in issue, further inquiry must occur as to what diligence was required of a prudent wharfinger, and only then can the District Court determine whether a failure to implement those procedures proximately caused the accident. 32 *213 Therefore, because factual issues remain to be resolved if Frescati’s negligence claim becomes relevant, we also remand for further proceedings, as necessary, on this claim. B. Negligent Misrepresentation Frescati argues that CARCO’s failure to inform the Athos I of the reduction in maximum draft at its facility’s ship dock prior to the vessel’s arrival was a negligent misrepresentation. The District Court held otherwise, reasoning that “the area of concern was not the area where the casualty occurred and the draft at the berth was factually irrelevant to the casualty.” In re Frescati, 2011 WL 1436878, at *5. We reach essentially the same result. Negligent misrepresentation stems from a failure to exercise reasonable care in supplying incorrect information during the course of a business transaction. Coastal (Berm.) Ltd. v. E.W. Saybolt & Co., Inc., 826 F.2d 424, 428 (5th Cir.1987) (citing Grass v. Crédito Mexicano, S.A., 797 F.2d 220, 223 (5th Cir.1986)). The receiving party must rely on that false information and thereby suffer injury. Id. at 428-29 (citing same). This formulation, set out by § 552 of the Restatement (Second) of Torts, implicitly incorporates the standard elements of negligence: duty of care, a breach of that duty, injury, and causation. See J.E. Mamiye & Sons, Inc. v. Fid. Bank, 813 F.2d 610, 615 (3d Cir.1987); 1 Schoenbaum, supra, § 5-2, at 252. CARCO initially explained in its Port Manual that the allowable maximum draft at its Paulsboro facility was 38 feet, but this “may change from time to time and should be verified prior to the vessel’s arrival.” J.A. at 1095 (CITGO Terminal Regulations for Vessels ¶ 2). On November 22, 2004, four days before the Athos I arrived, CARCO’s Port Captain Rankine announced internally that “the maximum draft at Paulsboro berth # 1 (ship dock) has been reduced to 36-00 feet.” J.A. at 1702. No one informed the Athos I of the change (and apparently its personnel did not inquire). This meant that the Athos I would have to enter CARCO’s port under an exception to the maximum draft, and in any event Port Captain Rankine was comfortable with this because the Athos I would not be lying in the shallower area next to its dock that motivated the draft reduction. 33 Rankine Test. 41:22-42:3, Nov. 22, 2010. On its terms, the reduction was limited to CARCO’s ship dock. Although Frescati argues that the Athos I would not have berthed at CARCO’s facility (its actual ship dock, but not the approach to it through the Anchorage) so early in the rising tide if its crew had known of the reduction in maximum allowable draft, this is irrelevant to its decision to enter Anchorage Number Nine — the site of the submerged anchor. In this context, any misrepresentation about the ship dock is factually irrelevant to the accident because it did not occur at *214 the dock, but rather 900 feet out in the Anchorage. There was no injury sustained that resulted from the failure to note the draft reduction at or immediately adjacent to CARCO’s dock. Frescati’s negligent misrepresentation claim thus fails on its merits as a matter of law. VI. Effect of the Government’s Settlement With CARCO In its limited settlement agreement with the Government, CARCO promised not to demand that the court reduce or offset the damages awarded to the United States against [CARCO] in the Lawsuit based on evidence that the negligence or fault of the United States in failing to detect, mark and/or remove underwater obstructions to navigation in the navigable waters of the Delaware River caused or contributed to the ATHOS I Incident. J.A. at 95 (Release ¶ 3.1(b)). It thus asks us to preclude CARCO on remand from raising any equitable defense premised on the Government’s regulation of the Anchorage. CARCO responds that it retained unspecified equitable defenses relevant to defending against, inter alia, the contractual claims, and that the Government conflates defenses to these claims with violations of CARCO’s promise to forbear making claims against the Government sounding in tort to reduce or offset damages awarded to it. 34 The Government also argues that the District Court mistakenly denied its earlier motion for summary judgment on CARCO’s defense of equitable recoupment, 35 as that defense was really just a disguised attempt for indemnity or contribution payments. After hearing oral argument, the District Court denied the Government’s pretrial motion on the ground “that the question of subrogation defenses [by CARCO] is better resolved with the benefit of a full trial record.” J.A. at 101. CARCO claims that the Government failed to follow up at trial, and thus waived the issue. We agree, as we see no indication that the Government renewed its argument at trial (or argued before us how the issue has not been waived). Thus, we decline to preclude CARCO from revisiting any previously raised equitable defense to the Government’s subrogation claims. VII. Conclusion Although remand is appropriate because the District Court failed to set out separate findings of fact and conclusions of law as required by Federal Rule of Civil Procedure 52(a)(1), our legal conclusions also make it necessary to remand for factual findings. We conclude that the Athos I, and Fres-cati as its owner, are beneficiaries of CAR-CO’s contractual safe berth warranty. *215 This was an express assurance that CAR-CO’s port would be safe for the Athos I within the scope of its invitation — that is, drawing 37 feet or less. Therefore, on remand it will need to be determined whether this amount of clearance was actually provided. This analysis may require inquiries into the arriving draft of the Athos I and, if the vessel was drawing more than the agreed-upon depth of 37 feet, the depth and positioning of the anchor. CARCO’s assertion of the named port exception is unavailing. Even if it were eligible on the type of notice given to the Athos I, its crew did not have an opportunity to accept a hazard (the anchor) that was unknown to the parties prior to the accident, and the exception is inapplicable. We further conclude that, as this case is primarily a contractual one, analysis of Frescati’s negligence claim is required only if the contractual safe berth warranty of CARCO is deemed satisfied. In that event, because we conclude that the accident occurred within the approach to CARCO’s terminal, the District Court would need to determine the appropriate standard of care, whether it was breached, and, if so, was that breach a cause of the spill. The negligent misrepresentation claim, however, fails for lack of factual causation because the alleged misrepresentation applied to an area unrelated to the accident. Finally, we conclude that the Government has waived its reliance on its partial settlement agreement in challenging CAR-CO’s defenses to liability. We thus affirm in part, vacate in part the District Court’s judgment orders of April 12, 2011 against Frescati and the Government, and remand for further proceedings consistent with this opinion. Further appeals relating to this case will be referred to the current panel. Appendix A [[Image here]] Footnotes [5] The stipulation suggests that the anchor was not mentioned in the report ultimately issued by the University of Delaware professors. See J.A. at 1310-12. Instead, it seems that it was not until after this litigation began that the parties obtained the 2001 side scan sonar data and agreed that it revealed the anchor's presence. [1] The term "charter party” may be confusing in that it does not refer to an entity, but a document. This is due to its historical genesis, deriving from the phrase "charta partita, i.e., a deed of writing divided.” Black’s Law Dictionary 268 (9th ed.2009) (quoting Frank L. Maraist, Admiralty in a Nutshell 44-45 (3d ed.1996)). The charta partita was literally a *191 divided document, the owner and the charterer each retaining one half of the agreement. Id. [2] It has been observed that [t]he fundamental difference between voyage and time charters is how the freight or "charter hire” is calculated. A voyage charterparty specifies the amount due for carrying a specified cargo on a specified voyage (or series of voyages), regardless of how long a particular voyage takes. A time charterparty specifies the amount due for each day that the vessel is "on hire,” regardless of how many voyages are completed. David W. Robertson et al., Admiralty and Maritime Law in the United States 335 (2d ed.2008). [3] A ship's master is its commander and captain. Black’s Law Dictionary, supra, at 1065. [4] An allision is ''[t]he contact of a vessel with a stationary object such as an anchored vessel or a pier.” Black’s Law Dictionary, supra, at 88. [6] In February 2007, Frescati applied to have its liability exonerated pursuant to 33 U.S.C. § 2703(a)(3). That subsection directs that a responsible party is not liable for the acts or omissions of a third party. In this case, that third party would have been the unknown anchor-dropper. It is unclear why Frescati withdrew this claim in 2008. [7] The Docking Pilot Association ("DPA”) Guidelines provide directives for the appropriate docking times for vessels of different sizes. The DPA Guidelines were developed after discussion with CARCO’s previous Port Captain and were based in part on CARCO’s desire to maximize the number of vessels that could dock at its berth. J.A. at 1104; Quillen Dep. 11:12-20, Sept. 2, 2010. [8] CARCO makes a belated argument that Crumady and Waterman are of dubious prece-dential value in light of the 1972 amendments to the Longshore and Harbor Workers’ Compensation Act. These amendments required negligence (as opposed to an unsafe condition) for a longshoreman to recover against a ship owner, and abolished the ship owner's right of indemnity against the stevedore. See 33 U.S.C. § 905(b); Scindia Steam Nav. Co., Ltd. v. De Los Santos, 451 U.S. 156, 164-65 (1981). This legislative exclusion, however, does not undermine the fundamental premise that a ship owner may benefit from an arrangement between third parties. As such, Judge Posner has noted that, following this amendment, "indemnity has continued to be sought in cases not involving longshoremen and hence not within the scope of the Long-shore!! land Harbor Workers’ Compensation Act.” Hillier v. S. Towing Co., 714 F.2d 714, 718-19 (7th Cir. 1983) (Posner, J.). [9] Insofar as CARCO cites to Bunge Corp. v. MV Furness Bridge, 390 F.Supp. 603, 604 (E.D.La.1974), it is unpersuasive, as its conclusion that the owner was not a third-party beneficiary of the sub-charterer's safe berth warranty is unsupported by any reasoning. Further, this issue was abandoned when the Court later resolved the merits of the claim and held that the sub-charterer had "violated a legal duty [in tort] whether or not it also had a contractual one.” Bunge Corp. v. MV Furness Bridge, 396 F.Supp. 852, 858. (E.D.La.1975), rev’d, 558 F.2d 790 (5th Cir. 1977). On appeal, the Court of Appeals for the Fifth Circuit agreed that the issue of contractual liability was "irrelevant” because none of the parties could have intended to warrant complete safety of an inadequately small wharf. 558 F.2d at 801-02. [10] Under the time charter, Frescati remained responsible for insuring, maintaining, and restoring the Athos I throughout the term of the charter. J.A. at 1447-48 (Time Charter Party ¶¶ 3, 6). [11] Although we ultimately conclude that the full safe berth warranty from CARCO to Star Tankers is an express assurance made without regard to the amount of diligence taken by the charterer,, see infra Part IV.B, Star Tankers only promised due diligence to Frescati, J.A. at 1448 (Time Charter Party 14). [12] On the facts before us, we need not define the outer geographical bounds of the safe berth/safe port warranty. At oral argument CARCO conceded that the warranty — if applicable — “would include the area in and around Paulsboro,” including the Anchorage. Oral Arg. Tr. 62:18-64:3, Sept. 20, 2012. [13] Gilmore's book has been described as being more adapted for the teacher than for the active lawyer or judge. As teachers, the authors are interested in controversy. Wherever they can find it, in the long past or in the nearer present, they stir it up, and frequently label it 'confusion.' ... It is all very interesting; but in the various admiralty fields — except personal injury and death — most of the old controversies have long been settled. Therefore, our authors tend to give a picture which does not resemble the daily grist of today. Sometimes indeed, straining to keep old battle-fires ablaze, they sprinkle harsh words on the judges who settled the old disputes.... On the whole, this is a teaching book rather than an office and courtroom work of reference; and it must be read as such. Arnold W. Rnauth, Book Review, 58 Colum. L.Rev. 425, 426-28 (1958) (reviewing Grant Gilmore & Charles L. Black, Jr., The Law of Admiralty (1957)). [14] Orduna also noted that a due diligence standard would not upset a master’s ability to *202 rely on a safe berth warranty in rejecting an unsafe port. 913 F.2d at 1156. This goes only so far, as it addresses but half of the safe berth warranty’s protection, which is both to provide a master with a contractual excuse for avoiding an unsafe port and to protect for damages actually sustained in unsafe ports. Additionally, to the extent Orduna relied on Atkins v. Fibre Disintegrating Co., 2 F.Cas. 78 (E.D.N.Y.1868), offd sub nom. Atkins v. The Disintegrating Co., 85 U.S. 272, 299, 18 Wall. 272, 21 L.Ed. 841 (1873), we are similarly unpersuaded. While Atkins featured a safe berth warranty, id. at 79, it was essentially an application of the named port exception. See infra Part IV.D. As the ship's master made outside inquiries and was fully aware of the port’s dangers and yet did not object, he waived his right to complain later for damage. Id. at 79-80. [15] Specifically, Gilmore & Black would find an actionable wrong for charterers directing ships to ports with known dangers, and suggest that a charterer may sometimes be "so situated as reasonably to be charged with a duty of inquiry, particularly as to berth.” Gilmore & Black, supra, § 4-4, at 205. [16] Though not dispositive, we also note that adhering to the Second Circuit’s view on this issue promotes uniformity of maritime law along the mid-Atlantic seaboard. See Sea-Land Serv., Inc. v. Dir., Office of Workers’ Comp. Programs, 552 F.2d 985, 995-96 n. 18a (3d Cir.1977) (noting deference pursuant to federal comity and uniformity in maritime law to the Second Circuit, "since [the Third Circuit] shares appellate review with the Second Circuit over the geographical area comprising one of the country’s major east coast harbor complexes”). [17] As already mentioned, the time charter party between Star Tankers and Frescati contains such a standard, as it is predicated on a Shelltime 4 form. See Coghlin et al., supra, ¶ 10.54. [18] We are also unpersuaded that this warranty applies only to known hazards. This would effectively undermine the more strict nature of the warranty by requiring some level of due diligence, which, for the reasons above, we do not believe is the case. [19] We note there is minor disagreement as to this particular figure. While the record suggests that the Athos I was represented as drawing 36'6", Frescati explains that it was actually 367". This one-inch difference is on its face irrelevant to our analysis, as both drafts are less than 37 feet. [20] Of course, this is ultimately a factual matter for remand. As such, we also note that the Voyage Charter between CARCO and Star Tankers indicates that the "[l]oaded draft of Vessel on assigned summer freeboard [is] 12.423 meters [40.76 feet] ... in salt water.” J.A. at 1220 (Tanker Voyage Charter Party, Part' I.A). While we understand this to mean that the Athos I could draw over 40 feet in salt water if filled to its summer capacity, the facts before us appear to indicate that it was directed to arrive at CARCO’s port drawing 37 feet or less, and that this was the understood basis for the safe berth warranty. [21] We note that there is record evidence suggesting that the promised 37 feet of clearance was indeed afforded, namely that Dr. Tray-kovski opined that there was — in his most conservative estimate — between 37.2 and 37.8 feet of water not only above the riverbed but the anchor itself (presumably at low tide). Traykovski Test. 49:12-50:24, Nov. 4, 2010. [22] Although the warranty exception for abnormal weather conditions is not at issue here, CARCO argues that the exceptions for bad navigation and seamanship apply. CAR-CO's Br. at 77, 80; see also Coghlin et al., supra, ¶¶ 10.148, 10.166 (citations omitted); Cooke et al., supra, ¶ 5.151 (citation omitted); Paragon, 310 F.2d at 173-74 (quoting Constantine & Pickering S.S. Co. v. W. India S.S. Co., 199 F. 964, 967-68 (S.D.N.Y.1912)) ("It is true that one liable for violating a safe berth clause 'may lessen the amount of damages for which he is responsible by showing negligence, or even lack of diligence, on the part of the person wronged, in failing to take steps to lessen certain or even probable damages.’ ”). CARCO argues that the vessel’s master and the navigation officer believed they were docking at high tide, and in fact were not (as the tide at the time of the accident was rising but an hour removed from low tide). However, we find no indication in the record that the Athos I was attempting to dock at an inappropriate time. [23] If the vessel is found to have been drawing more than 37 feet, this could potentially reduce CARCO's liability even if it were determined that a safe berth was not provided. In this circumstance, the commentators note a trend in which damages resulting from both a breach of a safe berth warranty and the master’s negligence may appropriately be split between the parties. Cooke et al., supra, ¶ 5.152; 2A Sturley, supra, § 175, at 17-26; see also Ore Carriers of Liber., Inc. v. Navigen Co., 435 F.2d 549, 550-51 (2d Cir.1970) (affirming an order dividing a ship's damages between the owner and charterer where the charterer had warranted a safe port, but the owner nonetheless proceeded "with full knowledge of the probable unavailability of tug assistance,” which was hazardous). In any event, these issues can also be resolved on remand. [24] Although it never uses the term "named port exception,” Atkins v. Fibre Disintegrating Co., 2 F.Cas. 78 (E.D.N.Y.1868), aff'd sub nom. Atkins v. The Disintegrating Co., 85 U.S. 272, 299, 18 Wall. 272, 21 L.Ed. 841 (1873), is a paradigm for the exception. There, "the peril of the port was such that no vessel of [the ship’s] size could get out without making her safety from the reefs dependent entirely upon the continuance of the breeze.” Id. at 79. Predictably, the breeze failed, and the ship was damaged on the reef. Id. at 78. The trial court concluded, however, that the master could not rely on the agent's representation that the port was safe because he failed to object to the port after having "made inquiries ... as to the character of the port, which was, moreover, fully described in the Coast Pilot [the official publication describing the coast].” Id. at 79-80. [25] The District Court determined that although underwater hazards are a well-known threat, none of the parties had any reason to believe that Anchorage Number Nine was likely to conceal such a menace. In re Fres-cati, 2011 WL 1436878, at *2. To the extent the Court later determined that knowledge "in general of lost or abandoned objects in the river” was sufficient to trigger this exception, id. at *7, that amounted to an error of law. This sort of general knowledge cannot be used to impute knowledge of a specific condition, and we see no evidence that the Delaware River was known to be particularly treacherous in this regard. [26] The grounding in Bouchard occurred “immediately adjacent to the ballast dock,” approximately 50 feet away. 389 F.Supp. at 81. This "immediately adjacent” language, however, does not refer to the beginning of the approach, but the location of the hazard within the approach. The District Court in our case adopted this language-citing Western Bulk Carriers, 1999 WL 1427719, 1999 U.S. Dist. LEXIS 22371, at *20 — as a "reasonable definition of 'approach.' ” In re Frescati, 2011 WL 1436878, at *4. We believe this interpreted Bouchard incorrectly. [27] CARCO argues that this reference to "dominion and control” is a prerequisite to Bou-chard 's holding. We do not view control as a requirement, but as a fact of that case where the port was also deemed negligent for failing to warn of shallow waters in an area directly off its dock where it had previously dredged. 389 F.Supp. at 80, 83. Instead, in relying primarily on Smith v. Burnett, Bouchard held that the terminal owner simply "had a duty to ascertain any imminent dangers to [the ship] as it approached.” Id. at 83. Further, to any extent Bouchard does suggest that control is required, we disagree for the reasons explained below. [28] In Smith v. Burnett, the United States Supreme Court quoted a Massachusetts Supreme Court case making a similar comparison where a defendant failed to warn a schooner of a rock it knew of adjacent to its wharf. This case cannot be distinguished in principle from that of the owner of land adjoining a highway, who, knowing that there was a large rock or a deep pit between the traveled part of the highway and his own gate, should tell a carrier, bringing goods to his house at night, to drive in, without warning him of the defect, and who would be equally liable for'an injury sustained in acting upon his invitation, whether he did or did not own the soil under the highway. 173 U.S. at 434, 19 S.Ct. 442 (quoting Carleton v. Franconia Iron & Steel Co., 99 Mass. 216, 219 (1868) (internal quotation marks omitted)). [29] In further support of this position, CARCO cites to Sonat Marine Inc. v. Belcher Oil Co., 629 F.Supp. 1319 (D.N.J.1985), aff'd, 787 F.2d 583 (3d Cir.1986) (table). That case, however, does not apply on its facts, and uses a wharfinger’s assumption of control to expand, rather than limit, the scope of its liability. Specifically, that wharfinger took the initiative secretly to widen its approach because "it recognized that larger vessels had problems entering the barge berth and required a greater margin of safety." Id. at 1322. Insofar as the terminal operator had "assumed sufficient control over that area to attempt to ensure a proper approach to the ship and barge terminal,” id. at 1327, it was deemed negligent for "failfing] to use means adequate[, such as side scans or wire drags,] to ensure that the new area where it thought larger barges could safely go was free of obstructions,” id. at 1325. Control aside, the District of New Jersey Court also noted that a "safe approach to the berth had to include the additional ... area.” Id. at 1326. [30] That the appeal of The Moorcock was operating under a theory of an implied contractual warranty does not reduce its import for purposes of this analysis. [1889] 14 P.D. 64 at 68 (Eng.). [31] In evaluating the specific nature of this duty, the parties point to no statute on point and our research reveals none. As to custom, it "is only evidence of a standard of care[,] and violation of custom or adherence to it does not necessarily constitute negligence or lack of negligence.” In re J.E. Brenneman Co., 322 F.2d 846, 855 (3d Cir.1963) (citations omitted); Norton v. Ry. Express Agency, Inc., 412 F.2d 112, 114 (3d Cir.1969) ("Although not controlling, custom and practice may be shown to establish the standard of care to which the party charged with the wrongful act may be required to conform.”). The District Court also determined that no industry custom would have "put CARCO on notice that it should scan into the Anchorage.” In reFrescati, 2011 WL 1436878, at *4. It is unclear if this apparent factual finding refers to other River terminals not searching their full approaches, federal waters generally, or Anchorage Number Nine specifically. Unfortunately, a review of the record leaves us similarly adrift. While several trial witnesses testified that they did not know of any Delaware River terminal taking precautionary action within federal waters, the Chief of Operations Division for the U.S. Army Corps of Engineers suggested that at least one terminal had surveyed the federal waters preceding its berth. See DePasquale Test. 104:20-105:13, *212 Oct. 6, 2010. Ultimately, the record is unhelpful on this point because we do not know if any of the terminals on the River had an approach that also traversed federal waters like CARCO’s did. Of course, the only relevant consideration for custom would be similarly situated terminals, and we are unable to make any meaningful assessment of industry custom on these facts. [32] We note that the District Court was "not convinced that had the area been scanned the anchor would perforce have been detect *213 ed....” In re Frescati, 2011 WL 1436878, at *4. We interpret the Court's remark as contemplating the effort required to detect the anchor absent an incident, as the anchor was in fact discovered with the use of side-scan technology. [33] Rankine testified that such exceptions are common in the industry, and that he was not concerned for the Athos I because a ship drawing 37'3" had sat through low water just ten days before without harm. Rankine Test. 38:22-23, 41:22-42:9, Nov. 22, 2010. When the trial judge inquired about the rationale for making regular exceptions, Rankine replied that he was required by the guidelines to make the reduction, but that he did not "have any worries about the depth of water in the area where the ship was going to sit.” Id. at 45:18-25. [34] The Government argues that CARCO has attempted to circumvent this partial settlement agreement by presenting against it negligence claims couched as equitable defenses. CARCO explicitly retained "the right to raise affirmative defenses under any theory or doctrine of law or equity, the right to assert setoff or recoupment and the right to assert compulsory or non-compulsory counterclaims other than a Claim for Contribution or Indemnity....” J.A. at 97 (Release ¶ 4.2). It was further agreed that the partial settlement would have no force as to CARCO’s suit with Frescati. Id. at 97-98 (Release ¶ 4.3). [35] Equitable recoupment is "[a] principle that diminishes a party’s right to recover a debt to the extent that the party holds money or property of the debtor to which the party has no right.” Black’s Law Dictionary, supra, at 618. The competing claims must arise from the "same transaction.” Phila. & Reading Corp. v. United States, 944 F.2d 1063, 1075 (3d Cir.1991) (quoting United States v. Dalm, 494 U.S. 596, 608, 110 S.Ct. 1361, 108 L.Ed.2d 548 (1990)).
