It is a general doctrine of the law that the owner of a vessel wrecked without his personal fault may relieve himself from all further personal liability on its account by abandoning it. If sunk through his fault, or if he still retains his title, he may be liable for damage which it occasions, or for maintaining a nuisance, or for obstructing navigable waters. If wrecked by unavoidable accident or without the owner's negligence, he may abandon all his rights and interest in what remains and be freed from all further responsibility; he will be under no obligation to remove it nor subject to indictment on its account, nor liable in damages for injuries caused by it. This abandonment is not required to be in any formal way but is shown by evidence of acts and intention. A notice to any public authorities who may be concerned, like local United States engineers, or harbor masters, or commissioners of wrecks, is often sufficient. Where, however, the owner does not abandon, he remains liable in many respects. The wreck may be a nuisance which the courts will compel him to abate at the suit of property owners injuriously affected. It may be an obstruction to navigable waters and the government may remove it at his expense or proceed against him criminally for such obstruction. Passing vessels may injure themselves against it or the riparian owner assert damages for the trespass.

5. Rights of Landowner.—

The owner of the shore on which a wreck is cast is not under any legal obligation to save it for the owner but he may take possession and protect it on the owner's account. If he does so, he will have a lien on the property for his expense and labor, at least, and may stand in the position of a salvor. If he does nothing himself, he may not resist the reasonable efforts of others to save the property for it is a very old rule of the common law, that an entry upon land to save goods which are in jeopardy of being lost or destroyed by water, fire or any like danger, is not a trespass, and this rule is applied to the rescue of ships cast ashore by the sea. At the same time, the owner of the shore will have a sufficient title to goods cast thereon to maintain an action for their value against third parties and salvors should be prompt in seeking the protection of the admiralty if their efforts are successful.

6. Owner's Rights.—

The owner's title to his wrecked ship or cargo remains in him until divested by his own act or by operation of law and he has the right to enter upon lands of another, upon which it may be cast, for the purpose of removing it; if prevented from so doing he may have his action of trover for its conversion or a replevin for possession.[31] In case his property was insured and abandoned to his underwriters, they become the full owners thereof and entitled to all his rights on the premises. These rules apply alike to ship and to cargo and to all the parts thereof. In Murphy v. Dunham, 38 Fed. 503, may be found an interesting discussion in regard to a wrecked cargo of coal. Dunham owned the schooner Burt which was lost in Lake Michigan with about 1,375 tons of coal on board. Murphy bought this cargo from the underwriters who had paid a total loss thereon. About two years afterwards, Dunham located the wreck and raised a quantity of the coal which he sold for the best price obtainable. These proceedings were without any license or authority from Murphy, who had purchased the cargo, and he then sued Dunham for tortious conversion. The court held that Murphy had a valid title and that Dunham was a trespasser in interfering with it; nevertheless if Dunham had promptly libeled it for salvage, his conduct not being marred by bad faith, the admiralty would have awarded him a substantial reward; but as he had assumed to dispose of it at private sale, he must answer in damages, although not as a willful trespasser or one acting in bad faith; he was accordingly held to respond for the value of the coal in the port where he sold it, less the actual and necessary expenses of its recovery. The Albany, 44 Fed. 431, is another opinion in regard to the rights of the owners of ship and cargo; as a result of that disaster, the cargo was plundered by wreckers and sold to many persons in the vicinity; the underwriters recovered it by actions in replevin wherever it could be found.

7. Rights of Government.—

The Act of March 3, 1899, (10 U. S. Comp. St. § 9920, etc.) contains provisions for the removal of wrecks in navigable waters by the Government. The obstruction may be broken up, removed, sold or otherwise disposed of by the Secretary of War at his discretion, without liability for any damage to the owners of the same. This authority may be delegated by the Secretary of War and permits the prompt removal of wrecks when they interfere with navigation. The rights and power of the Government to so dispose of wreckage can hardly be doubted and similar power probably exists in all foreign jurisdictions as well as in the several states.

8. Derelicts.—

Vessels abandoned and deserted at sea, with or without their cargoes, are termed derelicts and may be salved or destroyed by whomsoever can do so. They constitute very dangerous obstructions to navigation, especially when afloat on the ocean or the Great Lakes. The question whether or not a vessel is to be adjudged a derelict is decided by ascertaining, not what was actually the state of things when she was deserted by her master and crew, but what were their intentions and expectations when they quitted her. If they left in order to obtain assistance with the distinct purpose to return, there is no derelict. Prima facie, however, a deserted vessel at sea is a derelict and subject to salvage services, or, if not salvable, then to destruction by private parties or naval authorities. Salvage of derelicts is always liberally rewarded, sometimes to the amount of the whole recovery. If destroyed, the proceeding must be in entire good faith and, if so, there will be no liability to the owner. In the case of the River Mersey, 48 Fed. 686, that steamer had burned a scow found adrift at sea and was libeled for its destruction. It appears that the scow had broken adrift near one of the West Indies and become a dangerous factor in the navigation up and down the coast. The steamer took her in tow in order to drop her inside of the Gulf Stream but, finding this impossible on account of the weather, set her on fire in order to destroy her and so remove a dangerous obstruction to navigation. The owners of the scow alleged that they had not abandoned her and meant to send out a tug to bring her into port. The court dismissed the libel, saying that the destruction of such obstacles to the fairways of the sea, either when abandoned, or when proved not to be worth saving, is not tortious or actionable, but rather a praiseworthy and beneficent service, and, whether done by private or public ships, needs no statutory authority but is entirely justified under the law of necessity, for the protection of life and property, and for the manifest public good.
