The net tonnage (NT) of a ship shall be determined by the following formula:
4d                        N2
NT = K2 Vc [_______]2 + K3 (N1 + _______)
3D                       10
where: Vc = total volume of cargo spaces in cubic metres K2 = 0.2 + 0.02 log10
Vc or as specified in Schedule 3 GT = 10000 K3 = 1.25 ____________________
10000 where GT = gross tonnage calculated in accordance with regulation 6 D =
moulded depth amidships in metres d = moulded draught amidships in metres N1 =
number of passengers in cabins with not more than 8 berths N2 = number of
other passengers Provided that:

   (a)  the factor 4d [_____]2 3D shall not be taken as greater than unity;

   (b)  the term 4d K2 Vc [______]2 3D shall not be taken as less than 0.25
        GT;

   (c)  N1 and N2 shall be taken as zero when N1 + N2 is less than 13;

   (d)  NT shall not be taken as less than 0.30 GT.
