Sailboat Calculations
Bal./Disp = ballast (lbs)/ displacement (lbs)*100
A Ballast/Displacement ratio of 40 or more translates into a stiffer, more powerful boat that will be better able to stand up to the wind.
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.
Ballast / Displacement, % | 50.00 |
Capsize Screening Formula | 2.40 |
Rig and Sail Particulars
S.A. Fore = I * J / 2
This is the area of the fore triangle, calculated by multiplying I and J and dividing by 2.
S.A. Main = P * E / 2
This is the area of the main triangle, calculated by multiplying P and E and dividing by 2.
S.A. Total = S.A. Fore + S.A. Main
This is the sum of the fore and main sail areas.
Est. Forestay Length = √(I² + J²)
This is the length of the forestay, calculated using the Pythagorean theorem.
