walked to gain access to the middle section on which they were going to place another cover. The misplaced cover had therefore become as much a part of the ’tweendeck for continued prosecution of the work, as though it had been permanently fixed in place. It may appear strange that a longshoreman, who has the status of a seaman, should be allowed to recover because of unfitness of the ship arising from his own conduct in whole or in part. However, there is in this nothing inconsistent with the nature of the liability because it is imposed regardless of fault; to the prescribed extent the owner is an insurer, though he may have no means of learning of, or correcting, the defect. Indeed, as to these it is a kind of “Workmen’s Compensation Act”; though limited by the value of the ship and by the fact that it only covers injuries caused by the defects that we have mentioned. The following passage from Seas Shipping Co. v. Sieracki, 328 U.S. 85, 94, 66 S.Ct. 872, 877, 90 L.Ed. 1099, expresses the considerations that lie behind it. The owner
“is in position, as the worker is not, to distribute the loss in the shipping community which receives the service and should bear its cost.
“These and other considerations arising from the hazards which maritime service places on men who perform it, rather than any consensual basis of responsibility, have been the paramount influences dictating the shipowner’s liability for unseaworthiness as well as its absolute character. It is essentially a species of liability without fault, analogous to other well known instances in our law. * It is a form of absolute duty owing to all within the range of its humanitarian policy.”
The Court recently reaffirmed this doctrine in Alaska S. S. Co. v. Petterson, 347 U.S. 396, 74 S.Ct. 601, 98 L.Ed. 798, and we have since followed suit in Poignant v. United States, 2 Cir., 225 F.2d 595. Seas Shipping Co. v. Sieracki, supra, also held that the contributory negligence of a seaman is not a defense to an action based on the ship’s unseaworthiness ; although apparently it is a proper factor in fixing the amount of the recovery. Pope & Talbot v. Hawn, 346 U.S. 406, 74 S.Ct. 202, 98 L.Ed. 143. Be that as it may, Judge Ryan expressly found that the libellant was free from negligence, and the respondents have not challenged the finding.
The respondents also argue that there can be no maritime lien without a liability “in personam” for which it is security; and that, since we have found them free of personal liability, because the unseaworthiness arose after the demise, no lien can be imposed upon the ship. They cite as an authority for this some passages from The Western Maid, 257 U.S. 419, 42 S.Ct. 159, 66 L.Ed. 299; but the issue there was altogether foreign to the case at bar. All that the Supreme Court held was that since the United States had never consented to assume any liability for the torts of its agents, no maritime liens for collision could arise against ships owned by it, or demised to it, which could be enforced after the ships had passed to private persons, or after the demises had come to an end. In other words, the immunity of the United States extended not only to direct suits against itself, but to property that it owned absolutely, or as demisee, for conduct that, if committed by private persons, would have made them, or the property liable. It is still true that ships of the United States are as immune from maritime liens as they were before the Suits in Admiralty Act was passed, but § 743 gives relief “in personam” “wherever it shall appear that had the vessel or cargo been privately owned and possessed a libel in rem might have been maintained.” Therefore, we are to decide whether a suit will lie “in rem” by precisely the same rules as though only private persons had been concerned in the event.
That does not indeed answer the question whether a maritime lien can be imposed upon a ship for a claim on which no jural person is liable “in per
