1. In maritime terms, the deadweight of a vessel is the maximum weight of the cargo, crew, stores and bunkers that it can carry when loaded so that it settles in the water to the Plimsoll line. This is also measurable by the weight of the water the vessel displaces when fully loaded less the displacement when it was unloaded. 2. Deadweight cargo is cargo of such high density that a long ton (2240 lbs.) of such cargo can be stowed in less than 70 cubic feet.
