Sailboat Calculations
× S.A. / Displacement Formula
SA/D = SA (ft²) ÷ [Disp (lbs) / 64]^0.666
A sail area/displacement ratio below 16 would be considered under powered; 16 to 20 would indicate reasonably good performance; above 20 suggests relatively high performance.
× Capsize Screening Formula
CSF = Beam ÷ (Disp in cubic ft)^(1/3)
Designed to determine if a boat has blue water capability. The CSF compares beam with displacement since excess beam contributes to capsize and heavy displacement reduces capsize vulnerability. The boat is better suited for ocean passages (vs coastal cruising) if the result of the calculation is 2.0 or less. The lower the better.
