Definition of Deadweight Tonnage



Deadweight Tonnage refers to the carrying capacity of a vessel. Deadweight tonnage can be figured by taking the weight of a vessel which is not loaded with cargo and subtracting that figure from the weight of the loaded vessel.

See Displacement Tonnage


A vessel that weighs 2000 tons with crew and supplies takes on 350 tons of cargo in port. The deadweight of this vessel would therefore be 350 tons.
