D = molded depth amidships in meters, as ``molded depth'' is defined in

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

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
