Ratio Formulas:
Hull Speed = SQRT(LWL)*1.34
SA/D = Sail Area Displacement Ratio = SA / (Disp/64)2/3
D/L = Displacement Length = (Disp/2240)/0.01*LWL)3
BR = Ballast Ratio = Ballast/Disp
L/B = Length/Beam Ratio = LOA/Beam
LWL/B = Waterline Length/Beam Ratio = LWL/Beam
OR = Overhang Ratio = (LOA-LWL)/LOA
CSF = Capsize Screening Formula = Beam/((Disp/64.2)1/3
MCR = Motion Comfort Ratio = DISP / (.65*BEAM4/3(.7*LWL+.3*LOA))
M/F = Main/Foretriangle Ratio
All dimensions are in feet (decimal).
