Deadweight tonnage
Not to be confused with vessel displacement. The more heavily loaded a ship is, the lower she sits in the water. Maximum DWT is the amount of weight a ship can carry without riding dangerously low in the water. Scale for a 6,000 tonne DWT ship. Deadweight tonnage (also known as deadweight ; abbreviated to DWT , D.W.T. , d.w.t. , or dwt ) or tons deadweight (TDW) is a measure of how much weight a ship can carry, [1] [2] [3] not its weight, empty or in any degree of load. DWT is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. [1] DWT is often used to specify a ship's maximum permissible deadweight (i.e. when she is fully loaded so that her Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity.
