Definitions:


breadth:
The width or beam of the vessel. (Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

displacement tonnage:
A measurement of the weight of the vessel, usually used for warships. (Merchant ships are usually measured based on the volume of cargo space). Displacement is expressed either in long tons of 2,240 pounds or metric tonnes of 1,000 kg. Since the two units are very close in size (2,240 pounds = 1,016 kg and 1,000 kg = 2,205 pounds), it is common not to distinguish between them.
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

displacement light:
The weight of the vessel excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level.
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

displacement loaded:
The weight of the vessel including cargo, passengers, fuel, water, stores, dunnage and such other items necessary for use on a voyage, which brings the vessel down to her load draft.
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

draught:
The depth of water necessary to float a vessel fully loaded.
http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

deadweight tonnage:

Deadweight tonnage (also known as deadweight and "payload", abbreviated to DWT, D.W.T., d.w.t., or dwt) is a measure of how much weight a vessel is carrying or can safely carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. The term is often used to specify a vessel's maximum permissible deadweight, the DWT when the vessel is fully loaded so that its Plimsoll line is at the point of submersion, although it may also denote the actual DWT of a vessel not loaded to capacity.

Deadweight tonnage was historically expressed in long tons but is now usually given internationally in tonnes. Deadweight tonnage is not a measure of the vessel's displacement and should not be confused with gross tonnage or net tonnage (or their more archaic forms gross register tonnage or net register tonnage).
http://en.wikipedia.org/wiki/Deadweight_tonnage; 5 October 2010


The difference between displacement, light and displacement, loaded. A measure of the vessel's total carrying capacity.
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

gross tonnage:
The entire internal cubic capacity of the vessel expressed in tons of 100 cubic feet to the ton, except certain spaces with are exempted such as: peak and other tanks for water ballast, open forecastle bridge and poop, access of hatchways, certain light and air spaces, domes of skylights, condenser, anchor gear, steering gear, wheel house, galley and cabin for passengers. This characteristic is not a unit of weight.
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

net tonnage:
Obtained from the gross tonnage by deducting crew and navigating spaces and allowances for propulsion machinery. This characteristic is not a unit of weight.
(http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

height:
The height of the highest point of a vessel's structure (e.g. radar aerial, funnel, cranes, masthead) above her waterline.
(UKHO NP100/2009)

length overall:
The maximum length of the vessel (L.O.A.).
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)

length at waterline:
The vessel's length measured at the waterline (L.W.L.).
(Adapted from http://en.wikipedia.org/wiki/Ship_measurements; 24 July 2010)
