Definitions:

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)

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

draught:
the depth of the keel below the waterline at any point along the hull.
(UKHO NP100/2009)

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)

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 tonnage, 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 tonnage, 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)

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)

Panama Canal/Universal Measurement System net tonnage
the Panama Canal/Universal Measurement System (PC/UMS) is based on net tonnage, modified for Panama Canal purposes. PC/UMS is based on a mathematical formula to calculate a vessel's total volume; a PC/UMS net ton is equivalent to 100 cubic feet of capacity.
(Adapted from http://en.wikipedia.org/wiki/Tonnage 4 Oct 2010)

Suez Canal Net Tonnage
the Suez Canal Net Tonnage (SCNT) is derived with a number of modifications from the former net register tonnage of the Moorsom System and was established by the International Commission of Constantinople in its Protocol of 18 December 1873. It is still in use, as amended by the Rules of Navigation of the Suez Canal Authority, and is registered in the Suez Canal Tonnage Certificate.
(Adapted from http://en.wikipedia.org/wiki/Tonnage 4 Oct 2010)

Suez Canal Gross Tonnage
the Suez Canal Gross Tonnage (SCGT) is derived with a number of modifications from the former net register tonnage of the Moorsom System and was established by the International Commission of Constantinople in its Protocol of 18 December 1873. It is still in use, as amended by the Rules of Navigation of the Suez Canal Authority, and is registered in the Suez Canal Tonnage Certificate.
