|
|
It is the total volume of all enclosed spaces and all accommodation and cargo spaces. |
|
|
It is calculated
by the following formula: GT = K1V where: V = total volume of all enclosed spaces in cubic meters. K1=0.2 + 0.02 Log10V |

It is a measurement of the total earning capacity of a ship determined in accordance with merchant shipping (Tonnage) regulation. |
|
|
It is the total volume of only all cargo spaces. |
|
|
It is calculated
by the following formula: NT = K2Vc (4d/3D)2 + K3 (N1 + N2/10) where: Vc = total volume of all cargo spaces in cubic meters. K2=0.2 + 0.02 Log10Vc K3 = 1.25 (GT+10000)/10000 GT = Gross tonnage D = moulded depth and d = moulded draft, amidships, in meters. N1 = number of passengers in cabins with not more than eight berths. N2 = number of other passengers. |

Ton is the gross tonnage of a ship. |
