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.
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.
Ballast / Displacement Formula
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.
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.
| S.A. / Displacement | 30.47 |
| Ballast / Displacement, % | 14.15 |
