1. Definitions.—
Salvage may be defined as a legal liability which is created by the rescue of maritime property from perils of the sea. It may be quite independent of contract or agreement and these do not affect its nature. The word also designates the reward or compensation for the rescue and, sometimes, the property which is saved. Its essentials are maritime property in peril and a voluntary successful effort to save it. From the standpoint of the owner of the property, it is the price of safety.
The ingredients of a salvage service are, first, enterprise in the salvors in going out in tempestuous weather to assist a vessel in distress, risking their own lives to save their fellow-creatures, and to rescue the property of their fellow-subjects; secondly, the degree of danger and distress from which the property is rescued—whether it were in imminent peril, and almost certain to be lost if not at the time rescued and preserved; thirdly, the degree of labor and skill which the salvors incur and display, and the time occupied. Lastly, the value. Where all these circumstances concur, a large and liberal reward ought to be given; but where none, or scarcely any take place, the compensation can hardly be denominated a salvage compensation: it is little more than a remuneration pro opere et labore (The Clifton, 3 Hagg. Adm. 14, 48 [quoted with approval in Cope v. Drydock Co., 119 U. S. 625]).
General Average is also the price of safety under different circumstances. It is the contribution required of the parties interested in a maritime venture to compensate the sacrifice of a part for the safety of the rest. The typical instance is the jettison of cargo in order that the ship may be saved; the loss is equalized by a general average.
