1. Definitions.—
In a legal sense, the word wreck includes ships and cargoes, or any parts thereof, which have been cast on shore by the sea, and derelict applies to similar property abandoned on the sea. The terms should be understood as limited to things of a maritime nature and as including the old subdivisions of flotsam, jetsam and ligan,—flotsam being the name for the goods which float when the ship is sunk, jetsam meaning those which are jettisoned or thrown overboard, and ligan those cast into the sea but tied to a buoy or marker so that they might be found again. Derelict is the term applied to a thing which is abandoned at sea by those who were in charge of it, without any hope of recovery or intention of return.
