Deadweight tonnage
Deadweight tonnage (also known as deadweight, abbreviated to DWT, D.W.T., d.w.t., or dwt) is a measure of how much weight a ship is carrying or can safely carry.[1][2][3] It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers and crew.[1] The term is often used to specify a ship's maximum permissible deadweight, the DWT when the ship is fully loaded so that its Plimsoll line is at the point of submersion, although it may also denote the actual DWT of a ship not loaded to capacity.

Deadweight tonnage was historically expressed in long tons but is now usually given internationally in tonnes.[4] Deadweight tonnage is not a measure of the ship's displacement and should not be confused with gross register or net tonnage.
