Cases of collision between ships and wharves are very frequent and the damages caused thereby are a well recognized subject of marine insurance for which the underwriters agree to indemnify the vessel when it has been compelled to pay them. Damage to the wharf can not be recovered in the admiralty because the tort is not maritime; it is not consummated upon the water but on the land of which the wharf is a part. The wharf owner must, therefore, sue at common law or under local statutes; he has no maritime lien for the injury. On the other hand, the injuries received by the ship are consummated on the water and fall within the jurisdiction of the admiralty; the ship, however, can not libel the wharf because that is a fixed structure and not subject to maritime liens; its remedy is by a libel in personam against the wharf owner. If the wharf is a lawful structure and the ship negligently runs into it, full damages may be recovered at law. Where the structure is unlawful, the ship may recover its damages, in whole or in part, as the fault may lie, in an admiralty proceeding. Atlee v. Union Packet Co., 21 Wall. 389, was a case where a barge was sunk by a collision with a stone pier in the Mississippi river which had been placed there without authority of law. The pilot of the barge was also at fault in assuming to take her through the channel without posting himself about the location of the pier. The proceeding was a suit in admiralty by the owner of the barge against the owner of the pier, and, both being considered in fault, the damages were divided. In connection with the subject of admiralty jurisdiction it should be noted that while it declines to take cognizance of the damages sustained by the owners of fixed structures from collisions with vessels, the shipowners, by filing a petition under the Limited Liability Act, may draw their claims into the admiralty and enjoin their actions at common law (Richardson v. Harmon, 222, U. S. 96.).

Injuries are often sustained by docks and wharves when vessels make fast thereto in stress of weather and can not leave without exposing themselves to destruction. The rule is that the shipowner may not save his own property at the expense of the wharf-owner but must compensate him for the damage done by his ship, although the master had no alternative but to remain as he did. Vincent v. Company, 109 Minn. 456, is a decision in point, and Dutton v. Strong, 1 Black 23, should be read in the same connection.

8. Anchorage.—

The rights of navigation are usually paramount in all navigable waters and the right of anchorage is essential for a full enjoyment of such rights. These waters are, in many respects, like highways on the land, and there is a like privilege of stopping upon them, from time to time, as an incident to the right of travel thereon, subject to the reasonable requirements of traffic and the rights of abutting property. The right of passage extends to every part of the water, but the right of anchorage is confined to such places as are usual or reasonable, in view of local conditions. It does not imply the power to remain for long periods of time or to create a nuisance. Charges for anchorage may be made by the owner of the property used if it is an artificial one so that his work in improving or rendering it accessible forms a consideration for the amounts required. Generally, where only a natural roadstead is utilized in the course of navigation, it is no more subject to expense to the vessel than the temporary stopping of a vehicle upon a street.

The vessel, being at anchor in a proper place and otherwise complying with law, is not liable for damages sustained by collision with it, but, obviously, will have a strong case against the ship which runs her down. She ought not to anchor in an exposed situation, except in cases of necessity, and then only as long as the necessity prevails.

9. Obstructions to Navigation.—

Anchored vessels, like wharves, piers and the like, may constitute serious obstructions to navigation but this does not give others the right to run them down. Approaching vessels are still bound to use ordinary care and skill to avoid them. It is the duty of a ship under way, whether the vessel at anchor be properly or improperly anchored, to avoid, if it be possible with safety to herself, any collision whatever, and the courts have frequently held that even if a ship is brought up in the fairway of a river, if the other could with ordinary care have avoided her, the latter will be held solely to blame. In the case of the Future City, 184 U. S. 247, a tug and tow descending the Mississippi River at New Orleans, upon rounding a point came in collision with several battleships of the United States Navy, anchored in line on swinging chains. It appeared that they had taken up these berths in the fairway for descending vessels contrary to the usage of the port and against the advice of the Board of Harbor Masters, who, however, had no authority over naval vessels. There was abundance of good anchorage elsewhere in the harbor. The Supreme Court held the Government liable for the negligent anchoring of the naval vessels and that the tug was not guilty of contributory negligence in being unable, after rounding the point, to check the headway which the current of the river imparted to the tow.

The Court quoted with approval the language of Spencer on Marine Collisions:

It is negligence for a vessel to moor so near the entrance to a harbor that shipping, entering in stress of weather, is liable to become embarrassed by its presence; and where the usual difficulties of navigation make the entrance to a harbor a dangerous undertaking, it is especially reprehensible for a vessel to moor in a situation tending to increase these difficulties.

Where a vessel is at anchor in a proper place, and is observant of the precaution required by law, it is not liable for damages sustained by a vessel in motion colliding with it, but where it anchors in an unlawful position, or fails to observe the statutory requirements and such other precautions as good seamanship would suggest, it must suffer the consequences attending a violation of the law.
