	TONNAGE (Site not responding. Last check: 2007-10-14)
		The determination of the "tonnage" of a vessel is called measurement or admeasurement, the latter term being found mainly in legal documents.
		Thus to arrive at a net tonnage figure it is necessary to deduct from the gross tonnage the volume of such spaces as would have no earning capacity or room for cargo.
		Deadweight tonnage is the carrying capacity of a vessel figured by weight in terms of tons of 2240 pounds.

	Tonnage - Wikipedia, the free encyclopedia
		Tonnage is a measure of the size or cargo capacity of a ship.
		Gross Tonnage or Gross Register Tonnage is the internal volume of a vessel plus the space on exposed cargo decks (with some exemptions, depending on the assessing body).
		Historically, tonnage was the tax on tuns (casks) of wine shipped to England, mostly from Spain and Portugal, under a subsidy granted to the English crown by Parliament starting in the 14th century.

		There are five categories by which tonnage of a vessel is calculated: registered, gross register, net register, displacement and deadweight tonnage.
		Displacement Tonnage is the actual weight of the ship and is equal to the weight of water displaced by the vessel.

	Ship - Wikipedia, the free encyclopedia
		A number of different tonnage definitions exist,: most measure volume rather than weight and are used when describing merchant ships.
		The term displacement tonnage is normally applied when indicating the size of warships and equals the actual weight of a ship complete with crew, fuel, stores and water.
		The deadweight tonnage is the weight of cargo, stores, passengers etc. which when added to the weight of the ship's structure and equipment, will bring the vessel down to her designed waterline.

		Tonnage was originally the tax on tuns (casks) of wine shipped to England, mostly from Spain and Portugal, under a subsidy granted to the English crown by Parliament starting in the Fourteenth Century.
		Measurement of tonnage can be less than straightforward, not least because it's used to assess fees on commercial shipping.
		It's often used to rate naval vessels, since their weight is fairly constant and they're not subject to the kinds of port fees that are calculated on Register Tonnage.

	Review of Maritime Transport 2002
		Some 20.9% of world export tonnage was contributed by industrialized countries in North America and the developing countries of Latin America and the Caribbean, whose considerable exports of crude oil, iron ore, coal and grains constituted about two thirds of the hemisphere´s total tonnage.
		In Asia, developing countries expanded their deadweight tonnage to 117.0 million in early 2002 from 115.7 million the previous year, and now account for 14.2% of world tonnage, or 73.6% of the fleet of all developing countries.
		But this average masks differences by type of vessels and by region: Developing countries´ tankers, bulk carriers and container ships are generally somewhat younger than the rest of the world´s, unlike their general cargo vessels, which are two years older than the world average.

		For purposes of that provision only, deadweight tonnage shall be the maximum summer deadweight tonnage that was assigned to the vessel at the time of construction as reported in Lloyd's Register of Ships.
		Unless the vessel was structurally altered and remeasured to less than 40,000 DWT, this original deadweight tonnage shall be used for purposes of determining if the vessel requires the appropriate tug escort.
		(4) The deadweight tonnage provision of this rule is to be used solely for determining the required use of a tug escort.

	SHIPPING IN PORTSMOUTH SOUTHAMPTON & THE SOLENT (Site not responding. Last check: 2007-10-14)
		The tonnage of a ship has become important, one of its defining characteristics and a measurement which is carefully designed into the vessel by its naval architect.
		It is important chiefly because the tonnage of the vessel will be a figure that will be used to charge dues and fees throughout the ship's life, while those who may charter the ship will be interested in it as a measurement of the ship's cargo capacity, which will tend to dictate her earning power.
		Much more relevant than gross tonnage for a port would be the length and breadth of the ship while her draught may well require the provision of dredged channels and cause the port to incur expense.

		Net tonnage is the gross tonnage less the spaces used for the accommodation of the ship's Master, Officers, Crew, and the navigation and propulsion machinery.

	Ocean Navigator Online - Ton types
		Gross tonnage is the interior volume of a vessel as measured in units of 100 cubic feet.
		There is an even easier way to compute gross tonnage, however, using the simple formula:where: length is the length overall, not including bowsprits, boomkins, figureheads, etc.; breadth is a vessel's maximum beam; and depth is the vertical distance from gunwale to bottom of keel.
		Although displacement tonnage can change depending on the extent to which a vessel is loaded, and depending on whether it is submerged or running on the surface, the two measures of internal volume, gross and net tonnage, never change unless a vessel is reconstructed or redesigned in some way.

		Gross and net tonnage should not be confused with displacement tonnage, which is measured in terms of long tons (2240 pounds per long ton.) Deadweight tonnage (or the load weight capacity of a ship) is a type of displacement tonnage and is basically derived by subtracting the lightship weight from the full load weight.
		U.S. Tonnage Certificates, formerly known as Certificates of Admeasurement, document national tonnages, however these national certificates are not required to be kept on board Navy or USCG ships.
		Assure that all tonnage certificates issued by the USCG to Navy vessels be kept as part of the principal and accountable papers of such vessels.

		Ever since someone discovered a practical way to make the hull of a ship double as a container for oil, tankers have largely dominated liquid fuel transportation—and their role in the field is becoming more vital all the time.
		By the beginning of this year 1 5 tankers of at least 100,000 deadweight tons were plying the seas, according to John I. Jacobs and Company Limited and the Petroleum Press Service.
		Oil-carrying ships of more modest deadweight tonnage are especially useful for carrying petroleum products to destinations where the giant cargoes could not possibly be absorbed in one load ashore.

		The sharp declines in tonnage carried in these vessels to the Gulf and Pacific coasts do not so much reflect a reduction in the movement of products and small lots of crude, but rather the increasing use of vessels of 40,000 to 45,000 DWT to carry products.
		Comparison of the tonnage delivered by age of vessel in 1990 and 1994 indicates that vessels between 0 and 4 years and 20 to 24 years of age increased their amount of discharged oil significantly.
		The increase in government-owned vessels and tonnage on the Gulf and Atlantic coasts was due, in large part, to the increased presence of government-owned VLCCs in the Gulf and to increased crude oil

		This was primarily the result of a fleet expansion in developing Asia, where deadweight tonnage rose from 112.2 million in 1999 to 115.7 million in 2000.
		In the containership category, the proportion of vessels under four years of age is greatest in the fleet of developing countries, whereas general cargo vessels and all other vessels of developing countries are older than the world averages.
		The growth in GDP output of countries in East Asia (Japan; Republic of Korea; China; Hong Kong, China; Taiwan Province of China; and the major ASEAN countries) is evidence of continuing recovery from the financial crisis of 1997-1998, as is the region's merchandise trade boom in the year 2000, according to the UNCTAD report.
