The Deadweight Scale
The deadweight scale provides a method for estimating the additional draft or for determining the extra load that can be taken onboard when a vessel is being loaded in water of density less than that of salt water. This deadweight scale displays readings for freeboard, deadweight in salt water and in fresh water, draft of the ship (mean) displacement in salt water and in fresh water, tonnes per cm (TPC) in salt water and in fresh water, and moment to change trim 1 cm (MCTC) The use of the deadweight scale is illustrated with a worked example.
