Net tonnage (NT) is determined by the formula:
[GRAPHIC] [TIFF OMITTED] TR30SE97.006
in which: Vc = total volume of cargo spaces in cubic meters.K2 = 0.2 + 0.02 log10 Vc.[GRAPHIC] [TIFF OMITTED] TR30SE97.007 D = molded depth amidships in meters, as ``molded depth'' is defined in
Sec. 69.53.d = molded draft amidships in meters, as ``molded draft'' is defined in
Sec. 69.53.N1 = number of passengers in cabins with not more than eight
berths, as ``passenger'' is defined in Sec. 69.53.N2 = number of other passengers, as ``passenger'' is defined
in Sec. 69.53.GT = gross tonnage as determined under Sec. 69.57.N1 plus N2 must equal the total number of
passengers the vessel is permitted to carry as indicated on
the ship's Passenger Certificate. If N1 plus
N2 is less than 13, both N1 and
N2 are zero.

NT must not be less than 0.30 GT. [CGD 97-057, 62 FR 51045, Sept. 30, 1997]
