☞ There are in common use the following terms relating to tonnage: (a) Displacement. (b) Register tonnage, gross and net. (c) Freight tonnage. (d) Builders’ measurement. (e) Yacht measurement. The first is mainly used for war vessels, where the total weight is likely to be nearly constant. The second is the most important, being that used for commercial purposes. The third and fourth are different rules for ascertaining the actual burden-carrying power of a vessel, and the fifth is for the proper classification of pleasure craft. Gross tonnage expresses the total cubical interior of a vessel; net tonnage, the cubical space actually available for freight-carrying purposes. Rules for ascertaining these measurements are established by law.
