Sailboat Calculations
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.
