This replaced fixed factors for ship type and size by a formula CGT A GTB where A is a factor to account for the type of ship B is a factor to account for ship size and GT is the gross tonnage of the.

What is the gross tonnage of a ship. Some ships such as bulk carriers ore carriers and ships of under 500 gross tons may have reduced net tonnages. Although this term sounds like a reference to weight because it uses the term ton it is important to be aware that it is a volume measurement and does not provide information about the weight of a ship laden or empty. Gross Tonnage is a measure of the ships total interior volume and is calculated by multiplying the interior volume V of the ship in cubic meters by a variable known as K which varies depending on the ships overall volume.

The gross-registered tonnage was the enclosed under deck volume of the ship ft 3 and the net-registered tonnage was derived by deducting non-cargo carrying volumes from the gross figure thus reflecting earning capacity. Thus Oasis of the Seas at 220000 gross tons is considered a bigger cruise ship than Navigator of the Seas at 137000 gross tons. Gross tonnage is a measurement of the internal volume of a ship for the purpose of determining which regulations apply calculating port fees and so forth.

Gross tonnage is volume of all enclosed spaces of the ship Net tonnage is volume of all cargo carrying space of ship Comments 0 Like 3. The numerical value for a ships GT is always smaller than the numerical values for both her gross register tonnage and the GRT value expressed equivalently in cubic meters rather than cubic feet. The net tonnage is produced by a formula which is a function of the moulded volume of all cargo spaces of the ship.

The net tonnage shall not be taken as less than 30 per cent of the gross tonnage. Other ships such as roro vessels and car ferries will have increased net tonnages up to 300 per cent. Applies to vessels not to cargo.

Gross Tonnage is a measure of the ships total interior volume and is calculated by multiplying the interior volume V of the ship in cubic meters by a variable known as K which varies depending on the ships overall volume. The register of a vessel states both gross and net tonnage. Gross tonnage is calculated from the formula GT K1V where V is the volume of a ships enclosed spaces in cubic metres and K1 is a constant calculated by K1 02 002 log 10 V.

The internal volume of a water-going vessel has what is called gross tonnage. Since most vessels have an asymmetrical shape it can be difficult to determine the actual gross tonnage. Gross tonnage based on the product of LxBxT.
