Deadweight tonnage

Source: Wikipedia, the free encyclopedia.
Not to be confused with vessel displacement.
The more heavily loaded a ship is, the lower it 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 (DWT) is a measure of how much

ballast water, provisions, passengers, and crew.[1]

DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its

Plimsoll line
is at water level), although it may also denote the actual DWT of a ship not loaded to capacity.

Definition

Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage).

Deadweight tonnage was historically expressed in

light displacement (lightweight) of the ship.[5][6]
