delivered the opinion of the Court.
Respondent Santos, a longshoreman and an employee of respondent Seattle Stevedore Co., was injured while he was helping load the M/S Jalaratna, a vessel owned by petitioner Scindia Steam Navigation Co., Ltd. He later brought an action against Scindia pursuant to § 5 (b) of the Longshoremen’s and Harbor Workers’ Compensation Act (Act), as amended in 1972,1 which, as set forth in 33 U. S. C. § 905 (b), provides in relevant part as follows:
“In the event of injury to a person covered under this chapter caused by the negligence of a vessel, then such person, or anyone otherwise entitled to recover damages by reason thereof, may bring an action against such vessel as a third party in accordance with the provisions of section 933 of this title, and the employer shall not be liable to the vessel for such damages directly or indirectly and any agreements or warranties to the contrary [159]*159shall be void. . . . The liability of the vessel under this subsection shall not be based upon the warranty of seaworthiness or a breach thereof at the time the injury occurred. The remedy provided in this subsection shall be exclusive of all other remedies against the vessel except remedies available under this chapter.” 2
The District Court granted petitioner’s motion for summary judgment;3 the Court of Appeals, disagreeing with the District Court on both the facts and the law, reversed 'and' remanded for further proceedings. 598 F. 2d 480 (CA9 1979). We granted certiorari, 446 U. S. 934, because the Courts of Appeals are in considerable disagreement as to the meaning and application of § 905 (b).4
I
For present purposes, we take the facts from the opinion of the Court of Appeals, which properly viewed the case in the light most favorable to Santos, against whom summary judgment had been granted.
On December 10, 1972, Seattle Stevedore Co., pursuant to its undertaking with Scindia, was engaged in loading a cargo of wheat into a hold of the M/S Jalaratna. A winch, part of the ship’s gear, was being used to lower wooden pallets, each containing seventy 50-pound sacks of wheat, into the hold. Because of the location of the winch controls, the longshoreman operator relied on the hatch tender, another long[160]*160shoreman, to signal him when to start and stop the winch while lowering a pallet of sacks into the hold. Santos and three other longshoremen were in the hold. Their task was to remove sacks of wheat from the pallet and properly stow them.
On the day of the accident, as it had for the two previous days, the braking mechanism of the winch was malfunctioning in that it would not quickly stop the descent of a loaded pallet, which would continue to drop for several feet before coming to a stop. At the time important here, while a pallet was being lowered, the hatch tender signaled the winch operator to stop the descent of the load. The brake was applied, but the pallet did not stop before striking a pallet jack5 with some force and spilling about half the sacks of wheat from the pallet. The hatch tender signaled the operator to raise the pallet about 15 feet and, believing that the remaining sacks on the pallet were secure enough not to fall, permitted Santos and the other men to clear away the spilled sacks then lying below in the hold. Some minutes later, however, more sacks fell from the pallet, striking and injuring Santos. There was dispute as to whether the additional sacks fell because the suspended pallet was swinging back and forth or because while the pallet was suspended the braking mechanism slipped on three or four occasions, each time requiring the operator to raise it again, thus working loose the additional sacks that fell on Santos.
Relying on the legislative history of the 1972 Amendments to the Act, the District Court held that the negligence standards governing the longshoreman’s action against a shipowner under § 905 (b) are best expressed in Restatement (Second) of Torts §§ 343 and 343A (1965), which purport to [161]*161state the prevailing or preferred rules governing the liability of a possessor of land to an invitee.6 Under these land-based negligence standards, the District Court thought
“a shipowner is not liable for dangerous conditions created by the stevedore’s negligence while the stevedore [is] in exclusive control over the manner and area of the work . . . , nor is the shipowner under a duty to warn the stevedore or his employees of dangers or open and obvious defects which are known to the stevedore or his employees or which are so obvious and apparent that they may reasonably be expected to discover them.” 1976 A. M. C. 2583, 2585.
Based on the admissions of the parties and the depositions available to the court, the District Court concluded (1) that there was no dispute that the premises were in the exclusive control of Seattle during the loading operation and (2) that [162]*162even if Seindia knew or should have known of the defective winch,7 the condition of the winch “was open and obvious to the plaintiff” and “the fact that plaintiff undertook his actions free from any direction by the defendant while recognizing that the circumstances were so dangerous, is such that the defendant cannot be held liable as a matter of law.” Id., at 2586-2587. In addition, the District Court found that “the alleged defective condition of the winch had only a remote cause-of-fact relationship to plaintiff’s accident and could not have been the proximate cause thereof as a matter of law.” Id., at 2587. Hence, summary judgment was granted.8
Reversing, the Court of Appeals disagreed with the District Court and with other Courts of Appeals with respect to the applicable law. Sections 343 and 343A of the Restatement were improper measures of the shipowner’s liability for negligence under § 905 (b)9 because those sections in effect [163]*163incorporated notions of contributory negligence and assumption of risk that were inapplicable under the maritime law. Instead, the Court of Appeals declared the controlling standard under § 905 (b) to be the following:
“A vessel is subject to liability for injuries to longshoremen working on or near the vessel caused by conditions on the vessel if, but only if, the shipowner
“(a) knows of, or by the exercise of reasonable care would discover, the condition, and should realize that it involves an unreasonable risk of harm to such longshoremen, and
“(b) the shipowner fails to exercise reasonable care under the circumstances to protect the longshoremen against the danger.” 598 F. 2d, at 485.
Under this standard, Scindia’s duty to inspect did not end even if the vessel was turned over to the stevedore in safe condition. If conditions dangerous to the longshoremen subsequently developed, in light of the vessel’s practical opportunities to discover the dangers and remedy them, failure to do so could be negligence on its part.10

We granted certiorari, 446 U. S. 934, because the Courts of Appeals are in considerable disagreement as to the meaning and application of § 905 (b).4
I
For present purposes, we take the facts from the opinion of the Court of Appeals, which properly viewed the case in the light most favorable to Santos, against whom summary judgment had been granted.
On December 10, 1972, Seattle Stevedore Co., pursuant to its undertaking with Scindia, was engaged in loading a cargo of wheat into a hold of the M/S Jalaratna. A winch, part of the ship’s gear, was being used to lower wooden pallets, each containing seventy 50-pound sacks of wheat, into the hold. Because of the location of the winch controls, the longshoreman operator relied on the hatch tender, another long[160]*160shoreman, to signal him when to start and stop the winch while lowering a pallet of sacks into the hold. Santos and three other longshoremen were in the hold. Their task was to remove sacks of wheat from the pallet and properly stow them.
On the day of the accident, as it had for the two previous days, the braking mechanism of the winch was malfunctioning in that it would not quickly stop the descent of a loaded pallet, which would continue to drop for several feet before coming to a stop. At the time important here, while a pallet was being lowered, the hatch tender signaled the winch operator to stop the descent of the load. The brake was applied, but the pallet did not stop before striking a pallet jack5 with some force and spilling about half the sacks of wheat from the pallet. The hatch tender signaled the operator to raise the pallet about 15 feet and, believing that the remaining sacks on the pallet were secure enough not to fall, permitted Santos and the other men to clear away the spilled sacks then lying below in the hold. Some minutes later, however, more sacks fell from the pallet, striking and injuring Santos. There was dispute as to whether the additional sacks fell because the suspended pallet was swinging back and forth or because while the pallet was suspended the braking mechanism slipped on three or four occasions, each time requiring the operator to raise it again, thus working loose the additional sacks that fell on Santos.
Relying on the legislative history of the 1972 Amendments to the Act, the District Court held that the negligence standards governing the longshoreman’s action against a shipowner under § 905 (b) are best expressed in Restatement (Second) of Torts §§ 343 and 343A (1965), which purport to [161]*161state the prevailing or preferred rules governing the liability of a possessor of land to an invitee.6 Under these land-based negligence standards, the District Court thought
“a shipowner is not liable for dangerous conditions created by the stevedore’s negligence while the stevedore [is] in exclusive control over the manner and area of the work . . . , nor is the shipowner under a duty to warn the stevedore or his employees of dangers or open and obvious defects which are known to the stevedore or his employees or which are so obvious and apparent that they may reasonably be expected to discover them.” 1976 A. M. C. 2583, 2585.
Based on the admissions of the parties and the depositions available to the court, the District Court concluded (1) that there was no dispute that the premises were in the exclusive control of Seattle during the loading operation and (2) that [162]*162even if Seindia knew or should have known of the defective winch,7 the condition of the winch “was open and obvious to the plaintiff” and “the fact that plaintiff undertook his actions free from any direction by the defendant while recognizing that the circumstances were so dangerous, is such that the defendant cannot be held liable as a matter of law.” Id., at 2586-2587. In addition, the District Court found that “the alleged defective condition of the winch had only a remote cause-of-fact relationship to plaintiff’s accident and could not have been the proximate cause thereof as a matter of law.” Id., at 2587. Hence, summary judgment was granted.8
Reversing, the Court of Appeals disagreed with the District Court and with other Courts of Appeals with respect to the applicable law. Sections 343 and 343A of the Restatement were improper measures of the shipowner’s liability for negligence under § 905 (b)9 because those sections in effect [163]*163incorporated notions of contributory negligence and assumption of risk that were inapplicable under the maritime law. Instead, the Court of Appeals declared the controlling standard under § 905 (b) to be the following:
“A vessel is subject to liability for injuries to longshoremen working on or near the vessel caused by conditions on the vessel if, but only if, the shipowner
“(a) knows of, or by the exercise of reasonable care would discover, the condition, and should realize that it involves an unreasonable risk of harm to such longshoremen, and
“(b) the shipowner fails to exercise reasonable care under the circumstances to protect the longshoremen against the danger.” 598 F. 2d, at 485.
Under this standard, Scindia’s duty to inspect did not end even if the vessel was turned over to the stevedore in safe condition. If conditions dangerous to the longshoremen subsequently developed, in light of the vessel’s practical opportunities to discover the dangers and remedy them, failure to do so could be negligence on its part.10
[164]*164Under the Court of Appeals’ view of the law there were several material facts in dispute that were for a jury to resolve: whether the shipowner knew or should have known of the defective winch; whether Seattle was in exclusive control of the loading in the sense that only Seattle could have repaired the winch; whether the defective operation of the winch had caused the initial spillage of the sacks, thus necessitating a cleanup, or had later been the proximate cause of the additional sacks falling from the pallet and injuring Santos. Accordingly, the Court of Appeals set aside the judgment of the District Court and remanded for further proceedings.
II
Initially, we must briefly revisit the 1972 Amendments to the Act. Prior to 1972, a longshoreman injured while loading or unloading a ship could receive compensation payments and also have judgment against the shipowner if the injury was caused by the ship’s unseaworthiness or negligence. Seas Shipping Co. v. Sieracki, 328 U. S. 85 (1946). Proof of unseaworthiness required no proof of fault on the part of the shipowner other than an unsafe, injury-causing condition on the vessel. This was true even though the condition was [165]*165caused, created, or brought into play by the stevedore or its employees.11 In the latter event, the shipowner could recover over against a stevedore for breach of express or implied warranty to handle the cargo in a reasonably safe manner. Ryan Stevedoring Co. v. Pan-Atlantic S.S. Corp., 350 U. S. 124 (1956).12
The 1972 Amendments, particularly by adding § 905 (b), radically changed this scheme of things. The compensation payments due the longshoreman from the stevedore for injuries incurred in the course of his employment were substantially increased; the longshoreman’s right to recover for unseaworthiness was abolished; his right to recover from the shipowner for negligence was preserved in § 905 (b), which provided a statutory negligence action against the ship; and the stevedore’s obligation to indemnify the shipowner if the latter was held liable to the longshoreman was abolished.
Section 905 (b) did not specify the acts or omissions of the vessel that would constitute negligence. In light of the differences among the lower federal courts as to the construction and application of § 905 (b), neither can it be said that the legislative history, which has been analyzed and reanalyzed in the course of these cases, furnishes sure guidance for construing § 905 (b).13 Much was left to be resolved through [166]*166the “application of accepted principles of tort law and the ordinary process of litigation.” Rep., p. 11.
Ill
We held in Marine Terminals v. Burnside Shipping Co., 394 U. S. 404, 415 (1969), that the vessel owes to the stevedore and his longshoremen employees the duty of exercising due care “under the circumstances.” This duty extends at [167]*167least to exercising ordinary care under the circumstances to have the ship and its equipment in such condition that an expert and experienced stevedore will be able by the exercise of reasonable care to carry on its cargo operations with reasonable safety to persons and property, and to warning the stevedore of any hazards on the ship or with respect to its equipment that are known to the vessel or should be known to it in the exercise of reasonable care, that would likely be encountered by the stevedore in the course of his cargo operations and that are not known by the stevedore and would not be obvious to or anticipated by him if reasonably competent in the performance of his work. Id., at 416, n. 18. The shipowner thus has a duty with respect to the condition of the ship’s gear, equipment, tools, and work space to be used in the stevedoring operations; and if he fails at least to warn the stevedore of hidden danger which would have been known to him in the exercise of reasonable care, he has breached his duty and is liable if his negligence causes injury to a longshoreman. Petitioner concedes as much. Brief for Petitioner 20-21. It is also accepted that the vessel may be liable if it actively involves itself in the cargo operations and negligently injures a longshoreman or if it fails to exercise due care to avoid exposing longshoremen to harm from hazards they may encounter in areas, or from equipment, under the active control of the vessel during the stevedoring operation.
The parties, however, like the District Court and the Court of Appeals, are in sharp disagreement as' to the vessel’s duty under § 905 (b) once the stevedore’s cargo operations have begun. Scindia contends that the shipowner has no duty to supervise or inspect the stevedore’s cargo operations or to take reasonable care to discover dangerous conditions that develop or come to light during the loading or unloading. Scindia also submits that even if the vessel learns of the hazard, it has no duty to correct it and is entitled as a matter of law to rely on the stevedore to protect his employees from injury. This is true, Scindia argues, even though the hazard is an ob[168]*168viously defective ship’s winch being used by the stevedore and his longshoremen employees,14 and even if the winch was defective when the stevedore came aboard and the vessel is charged with knowledge of the condition. Respondents, on the other hand, defend the view of the Court of Appeals that the vessel is subject to a continuing duty to use reasonable care to discover dangerous conditions exposing longshoremen to unreasonable risk of harm and to exercise reasonable care under the circumstances to protect them. We are unable to agree wholly with either of these submissions.
Considering first the position of the Court of Appeals, we cannot agree that the vessel’s duty to the longshoreman requires the shipowner to inspect or supervise the stevedoring operation. Congress intended to make the vessel answerable for its own negligence and to terminate its automatic, faultless responsibility for conditions caused by the negligence or other defaults of the stevedore. Cases holding the vessel liable on the ground that it owed nondelegable duties to protect the longshoremen from injury were rejected.15 It would [169]*169be inconsistent with the Act to hold, nevertheless, that the shipowner has a continuing duty to take reasonable steps to discover and correct dangerous conditions that develop during the loading or unloading process. Such an approach would repeatedly result in holding the shipowner solely liable for conditions that are attributable to the stevedore, rather than the ship. True, the liability would be cast in terms of negligence rather than unseaworthiness, but the result would be much the same. “[C]reation of a shipowner’s duty to oversee the stevedore’s activity and insure the safety of longshoremen would . . . saddle the shipowner with precisely the sort of nondelegable duty that Congress sought to eliminate by amending section 905 (b).” Hurst v. Triad Shipping Co., 554 F. 2d 1237, 1249-1250, n. 35 (CA3 1977); Evans v. S.S. “Campeche,” 639 F. 2d 848, 856 (CA2 1981).16
[170]*170As a general matter, the shipowner may rely on the stevedore to avoid exposing the longshoremen to unreasonable hazards. Section 41 of the Act, 33 U. S. C. § 941, requires the stevedore, the longshoremen’s employer, to provide a “reasonably safe” place to work and to take such safeguards with respect to equipment and working conditions as the Secretary of Labor may determine to be necessary to avoid injury to longshoremen.17 The ship is not the common employer of the longshoremen 18 and owes no such statutory duty to them. Furthermore, as our cases indicate, the stevedore normally warrants to discharge his duties in a workmanlike manner; and although the 1972 Amendments relieved the stevedore of his duty to indemnify the shipowner for damages paid to longshoremen for injuries caused by the stevedore’s breach of warranty, they did not otherwise disturb the contractual undertaking of the stevedore nor the rightful expectation of the vessel that the stevedore would perform his task properly without supervision by the ship.
[171]*171The approach of the indemnity cases in this Court, beginning with Ryan Stevedoring Co. v. Pan-Atlantic S.S. Corp., 350 U. S. 124 (1956), was that the stevedore was in the best position to avoid accidents during cargo operations and that the shipowner could rely on the stevedore’s warranty to perform competently. In Italia Societa v. Oregon Stevedoring Co., 376 U. S. 315 (1964), for example, the vessel was found liable for injuries to a longshoreman caused by an unsea-worthy condition arising when the stevedore, without negligence, supplied defective equipment used in handling the cargo. We held the vessel entitled to recover over against the stevedore, saying:
“Oregon, a specialist in stevedoring, was hired to load and unload the petitioner’s vessels and to supply the ordinary equipment necessary for these operations. The defective rope which created the condition of unseaworthiness on the vessel and rendered the shipowner liable to the stevedore’s employee was supplied by Oregon, and the stevedoring operations in the course of which the longshoreman was injured were in the hands of the employees of Oregon. Not only did the agreement between the shipowner place control of the operations on the stevedore company, but Oregon was also charged under the contract with the supervision of these operations. Although none of these factors affect the shipowner’s primary liability to the injured employee of Oregon, since its duty to supply a seaworthy vessel is strict and nondelegable, and extends to those who perform the unloading and loading portion of the ship’s work, Seas Shipping Co. v. Sieracki, 328 U. S. 85, cf. Pope & Talbot v. Hawn, 346 U. S. 406, they demonstrate that Oregon was in a far better position than the shipowner to avoid the accident. The shipowner defers to the qualification of the stevedoring contractor in the [172]*172selection and use of equipment and relies on the competency of the stevedore company.” Id., at 322-323.19
The 1972 Amendments foreclosed indemnity of the shipowner by the stevedore in § 905 (b) cases; but they also rejected the notion of a nondelegable duty on the shipowner to provide a safe place to work and did not undermine the justifiable expectations of the vessel that the stevedore would perform with reasonable competence and see to the safety of the cargo operations.
We are of the view that absent contract provision, positive law, or custom to the contrary — none of which has been cited to us in this case — the shipowner has no general duty by way of supervision or inspection to exercise reasonable care to discover dangerous conditions that develop within the confines of the cargo operations that are assigned to the stevedore. The necessary consequence is that the shipowner is not liable to the longshoremen for injuries caused by dangers unknown to the owner and about which he had no duty to inform himself. This conclusion is plainly consistent with the congressional intent to foreclose the faultless liability of the shipowner based on a theory of unseaworthiness or nondelegable duty. The shipowner, within limits, is entitled to rely on the stevedore, and owes no duty to the longshoremen to inspect or supervise the cargo operations. To the extent that the judgment of the Court of Appeals rested on a contrary view, we disagree.
IV
We arrive at the more difficult and recurring issue involved in this case: What are the shipowner’s duties when he learns that an apparently dangerous condition exists or has developed in the cargo operation, which is known to the steve[173]*173dore and which may cause injury to the longshoreman? Must the owner take some action? Scindia and the District Court would have it that the vessel is entitled to rely on the expertise and responsibility of the stevedore and is not liable for injuries caused by dangers known by or obvious to the stevedore, who, if he fails to take proper precautions, is necessarily the sole and proximate cause of the injury. There is arguable support for this position in our cases.
In Crumady v. The J. H. Fisser, 358 U. S. 423 (1959), a ship’s winch had been set by ship’s officers to shut off the current at twice the safe working load of the unloading gear. The gear parted when subjected to undue strain because of the- negligence of the stevedore. The Court held the ship unseaworthy. Consistent with past cases, the Court declared that the longshoremen’s protection against unseaworthiness “imposes a duty which the owner of the vessel cannot delegate,” a duty which, as to appliances, “does not end with supplying them; he must keep them in order.” The shipowner “is not relieved of these responsibilities by turning control of the loading or unloading of the ship over to a stevedoring company.” Id., at 427. The Court, nevertheless, permitted the ship to recover over from the stevedore “since the negligence of the stevedores . . . brought the unseaworthiness of the vessel into play . . . .” Id., at 429.20
In Crumady, the Court declared that “those acting for the vessel owner” had adjusted the winch “in a way that made it unsafe and dangerous for the work at hand.” Id., at 427. It thus appeared that the vessel had at least been negligent, yet it was entitled to shift its entire liability to the stevedore [174]*174because it was entitled to rely on the stevedore’s undertaking to perforin in a workmanlike manner. Arguably, Scindia should likewise be justified in expecting Seattle to perform its undertaking and should therefore have no duty or responsibility with respect to the ship’s winch, which, if defective, was obviously so and which the stevedore continued to use.
The court below rejected this position, holding that if the vessel should realize that the condition presents an unreasonable risk of harm, it is liable if it “fails to exercise reasonable care under the circumstances” to protect the longshoremen. The court did not suggest how to recognize an “unreasonable risk” of harm from an obvious danger or suggest what reasonable care under the circumstances might be.
The Court of Appeals for the Second Circuit, while disagreeing with the duty-to-inspect thesis of the Court of Appeals in the present case, has also rejected this position, ruling that although the shipowner is normally entitled to rely on the stevedore to guard against hazards to its employees, “there may be circumstances in which it would not be reasonable for the shipowner to assume that the stevedore will correct the problem.” Evans v. S.S. “Campeche ” 639 F. 2d, at 856.21 As that court sees it, mere knowledge of the [175]*175danger would not be sufficient in itself to fasten such a duty on the shipowner, but if the shipowner should anticipate that the stevedore will not or cannot correct the danger and that the longshoremen cannot avoid it, then the shipowner’s duty is triggered to take steps, reasonable in the circumstances, to eliminate or neutralize the hazard. We are presently unprepared to agree that the shipowner has precisely the duty described by the Court of Appeals for the Second Circuit, but for the reasons that follow we agree that there are circumstances in which the shipowner has a duty to act where the danger to longshoremen arises from the malfunctioning of the ship’s gear being used in the cargo operations.
On the facts posited here, for two days prior to the accident, it had been apparent to those working with the winch that this equipment was malfunctioning. Even so, whether it could be safely used or whether it posed an unreasonable risk of harm to Santos or other longshoremen was a matter of judgment committed to the stevedore in the first instance. The malfunctioning being obvious and Seattle having continued to use it, Scindia submits that if it was aware of the condition or was charged with knowledge of it, it was nevertheless entitled to assume that Seattle, the specialist in loading and unloading, considered the equipment reasonably safe and was entitled to rely on that judgment.
Yet it is quite possible, it seems to us, that Seattle’s judgment in this respect was so obviously improvident that Scindia, if it knew of the defect and that Seattle was continuing to use it, should have realized the winch presented [176]*176an unreasonable risk of harm to the longshoremen,22 and that in such circumstances it had a duty to intervene and repair the ship’s winch. The same would be true if the defect existed from the outset and Scindia must be deemed to have been aware of its condition.
As we have indicated, the legal duties placed on the stevedore and the vessel’s justifiable expectations that those duties will be performed are relevant in determining whether the shipowner has breached its duty. The trial court, and where appropriate the jury, should thus be made aware of the scope of the stevedore’s duty under the positive law. But an equally necessary inquiry is whether the pertinent statutes, regulations, or custom place or assume a continuing duty on the vessel to repair defective ship’s gear being used by the stevedore in the cargo operation.23
The statutory duty of the stevedore under § 941 to provide a safe place to work has been implemented by the Safety and Health Regulations for Longshoring. 29 CFR § 1918.1 et seq. (1980). Subpart F of these regulations, § 1918.51 et seq., deals with the use of the ship’s gear by the stevedore. Section 1918.51 (b) provides that “[a]ny component of cargo handling gear . . . which is visibly unsafe shall not be used until made safe.” In addition, § 1918.53, dealing with cargo winches, provides that “[a]ny defect or malfunction of winches shall be reported immediately to the officer in charge of the vessel,” § 1918.53 (a) (5); that in the case of electrical winches “[w]hen the electromagnetic or other service brake is unable to hold the load, the winch shall not be used,” [177]*177§ 1918.53 (c)(1); and that “[e]mployees shall not be permitted to tamper with or adjust electric control circuits,” § 1918.53 (c)(2).24 Even in the absence of other statutory or regulatory law placing on the shipowner the obligation to repair a defective winch,25 a possible inference from the [178]*178provisions already described is that when a defective winch is discovered, it should not be repaired by the stevedore but should be reported to and repaired by the shipowner. If this is the case, the situation comes down to this: If Scindia was aware that the winch was malfunctioning to some degree, and if there was a jury issue as to whether it was so unsafe that the stevedore should have ceased using it, could the jury also have found that the winch was so clearly unsafe that Scindia should have intervened and stopped the loading operation until the winch was serviceable?
We raise these questions but do not answer them, since they are for the trial court in the first instance and since neither the trial nor appellate courts need deal with them unless there is sufficient evidence to submit to the jury either that the shipowner was aware of sufficient facts to conclude that the winch was not in proper order, or that the winch was defective when cargo operations began and that Scindia was chargeable with knowledge of its condition. The District Court concluded that there was no triable issue of fact as to whether the shipowner knew or should have known of the alleged condition of the winch. The Court of Appeals read the record quite differently, ruling that there was a disputed material fact, which the District Court should not itself have resolved, with respect to the shipowner’s actual or constructive knowledge of the condition of the winch. To the extent that this conclusion was based on the Court of Appeals’ erroneous view that the vessel should have known the facts because of its duty to inspect the stevedore’s cargo handling operation, it was infirm. But as we understand the opinion below, the Court of Appeals held that there was a triable issue as to whether the shipowner had actual knowledge of the failure in the winch’s braking mechanism or was chargeable with knowledge because the winch was defective from the outset. Based on our own examination of the record, we agree with the Court of Appeals in this respect and with its conclusion that the District Court erred in granting [179]*179summary judgment. The case should be returned to the District Court and, if necessary, tried to a jury under appropriate instructions.26
Accordingly, we affirm the judgment of the Court of Appeals and remand the case to that court for further proceedings consistent with this opinion.
So ordered.
The Chief Justice took no part in the decision of this case.
