Each vessel must be shown by design calculations to have a metacentric height (GM) in feet (meters) in each condition of loading and operation, that is not less than the value given by the following equation:[GRAPHIC] [TIFF OMITTED] TC01MR91.009where--N=number of passengers.W=displacement of the vessel in long (metric) tons.T=14 degrees or the angle of heel at which the deck edge is first submerged, whichever is less.b=distance in feet (meters) from the centerline of the vessel to the geometric center of the passenger deck on one side of the centerline.K=24 passengers/long ton (23.6 passengers/metric ton).
