Loaded displacement is the weight of the ship including cargo, passengers, fuel, water, stores, dunnage and such other items necessary for use on a voyage. These bring the ship down to its "load draft". [ 8 ] Full load displacement and loaded displacement have almost identical definitions. Full load is defined as the displacement of a vessel ...
Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage, was defined by the International Convention on Tonnage Measurement of Ships, 1969, adopted by the International Maritime Organization (IMO) in 1969, and came into ...

(Merchant ships display gross tonnage ; see tonnage), deadweight and the number of items it can carry i.e. TEU 20 ft equivalent units. Displacement is expressed in tonne (metric unit) ship built for USA will be in long tons, Warships are shown in displacement tons or tonne. To preserve secrecy, nations sometimes misstate a warship's displacement.
In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Although tonnage (volume) should not be confused with displacement (the actual mass of the vessel), the long ton (or imperial ton) of 2,240 lb is derived from the fact that a " tun " of wine typically weighed that much.
Gross tonnage and displacement are not equivalent and vary depending on the type of ton (e.g. metric or imperial) and how they are calculated. How gross tonnage is calculated has changed somewhat over time, but has always been a measure of cargo space (i.e., it is a measure of the volume of the cargo space), and figures for displacement also ...
Gross register tonnage (GRT, grt, g.r.t., gt), or gross registered tonnage, is a ship's total internal volume expressed in "register tons", each of which is equal to 100 cubic feet (2.83 m 3). Replaced by Gross Tonnage (GT), gross register tonnage uses the total permanently enclosed capacity of the vessel as its basis for volume.
Net register tonnage is not a measure of the weight of the ship or its cargo, and should not be confused with terms such as deadweight tonnage or displacement. Gross and net register tonnages were replaced by gross tonnage and net tonnage, respectively, when the International Maritime Organization (IMO) adopted The International Convention on ...
