delivered the opinion of the Court.
The question here involves the right to trial by jury under principles of maritime liability enunciated in
Ryan Stevedoring Co.
v.
Pan-Atlantic S. S. Corp.,
Petitioner’s claim for indemnity primarily rests on the contractual relationship between it and respondent. While the stevedoring contract contained no express indemnity clause,
1
it obligated respondent “to faithfully furnish such stevedoring services as may be required,” and to provide all necessary labor and supervision for “the proper and efficient conduct of the work.” As this Court said in
Ryan Stevedoring Co.
v.
Pan-Atlantic S. S. Corp., supra,
such language constitutes “a contractual undertaking to [perform] ‘with reasonable safety,’ ”
The F. E. Weyerhaeuser, the vessel upon which the accident occurred, had sailed from the West Coast with a cargo of lumber for New York and Boston, the ports where respondent was to perform the stevedoring operations. The vessel arrived in New York on January 25, 1952, and in the ensuing five days the deck load and part of the underdeck cargo was discharged. On January 30 the ship left New York, arriving in Boston the next day. Respondent’s crews boarded the vessel and the unloading continued. On the fifth day of the Boston operations one Connolly, a longshoreman employed by respondent, *566 was injured when struck on the head by a piece of wood while working in a lower hold. The parties agree that the wood must have fallen into the hold from the top of a temporary winch shelter which protected the winch drivers from the elements.
The evidence indicated that winch shelters are customarily erected by longshoremen at the beginning of their unloading operations. They consist of a scrap lumber framework with a tarpaulin stretched across the top. Because of their flimsy construction they are considered a hazard in the winds at sea, and “automatically” are torn down by the ship’s crew when the vessel leaves port. Both the captain and the second officer of the F. E. Weyerhaeuser testified that it would be carelessness on their part to allow winch shelters to remain in place when the vessel goes to sea. We need not discuss the details which may have led the jury to find for Connolly in the main case, but implicit in the jury verdict was a finding that the structure was on the ship when it arrived in Boston. 2 Respondent, through its employees stationed in New York, must have built the shelter while the ship was in New York harbor, 3 and we may assume that petitioner failed to remove it upon leaving for Boston. The record is silent as to the exact circumstances under which it was made available to respondent in Boston. It does appear, however, that the shelter was *567 used in the stevedoring operations by respondent’s Boston employees, in spite of the fact that respondent as well as petitioner must have known of its journey from New York and the possible effect of such a journey on an already flimsy structure. There was evidence that the shelter was not inspected by either party until the injury to Connolly five days after the arrival in Boston. 4
We believe that respondent’s contractual obligation to perform its duties with reasonable safety'related not only to the handling of cargo, as in
Ryan,
but also to the use of equipment incidental thereto, such as the winch shelter involved here.
American President Lines
v.
Marine Terminals Corp.,
In view of the new trial to which petitioner is entitled, we believe sound judicial administration requires us to point out that in the area of contractual indemnity an application of the theories of “active” or “passive” as well as “primary” or “secondary” negligence is inappropriate. Ryan Stevedoring Go. v. Pan-Atlantic S. S. Co., supra, at 132-133.
The judgment of the Court of Appeals is reversed and the case is remanded for proceedings in conformity with this opinion.
It is so ordered.
Notes
See, generally, Weinstock, The Employer’s Duty to Indemnify Shipowners for Damages Recovered by Harbor Workers, 103 U. of Pa. L. Rev. 321, 332-346 (1954).
The jury found for Connolly on the issue of negligence after being instructed as follows:
“Now, if you find from the evidence that the structure, that is, this shelter, was on the ship when it came into Boston Harbor and that the ship offered it to the stevedores to use and work with, and if you find that in permitting that to be there the ship was guilty of some act of negligence as T have defined it to you, then you could find a verdict for Mr. Connolly.”
There was undisputed evidence that the shelter could not have been assembled prior to the removal of the deck cargo in New York.
A witness testified that after the accident he stood on one of the winches to permit a view of the shelter top, which was approximately seven feet above the deck, and discovered a second piece of tarpaulin secured only by two loose pieces of wood similar to that which struck Connolly.
It should be noted that “[t]he shipowner’s action is not changed from one for a breach of contract to one for a tort simply because recovery may turn upon the standard of the performance of petitioner’s stevedoring service.” Ryan Stevedoring Co. v. Pan-Atlantic S. S. Corp., supra, at 134.
See Corbin, Contracts, §§571, 947, 1264; cf. Restatement, Contracts, §§ 295, 315.
The following explanation in the charge to the jury suggests that the trial judge intended to submit the third-party action upon return of the verdict in the main case:
“I shall ask you to go out and consider the claims of Mr. Connolly against the Weyerhaeuser Steamship Company first and then when you come back with your verdict on that I shall ask you to retire again and consider the issues in the second suit, namely Weyerhaeuser Steamship Company against the Nacirema Operating Company, and before I submit that second one to you I shall give you some instructions which apply peculiarly to that.”
