*NOTE: The coefficients and dimensions presented above are for that portion 

 of a single hull that. is below the 38 ft waterline. This draft corresponds 

 to the total height (minor axis) of the largest elliptical body section. The 

 total full-scale displacement, wetted surface, and draft, for a single hull, 

 are 50,500 tons S.W., 164,780 sq ft, and 69.5 ft, respectively . That portion 

 of the full-scale hull above the 38 ft waterline (strut) has a waterline 

 length (LWL) of 757.5 ft, a beam (B ) of 30.4 ft, and a waterplane coefficient 

 (Cy) of 0.515. X
