Deadweight

Although influencing its behaviour, displacement is not a direct measure of a ship's carrying capacity, that is, its earning power. To measure capacity deadweight and tonnage are used.

The deadweight, or deadmass in terms of mass, is the difference between the load displacement up to the minimum permitted freeboard and the lightweight or light displacement. The lightweight is the weight of the hull and machinery so the deadweight includes the cargo, fuel, water, crew and effects. The term cargo deadweight is used for the cargo alone. A table of deadweight against draught, for fresh and salt water, is provided to a ship's master in the form of a deadweight scale. This may be in the form of a diagram, a set of tables or, more likely these days, as software.
