Sailboat Calculations
HS = 1.34 × √LWL (in feet)
The maximum speed of a displacement hull (referring to a hull that travels through the water rather than on top of it, e.g. planing).
PPI = LWL Area × 5.333
The weight required to sink the yacht one inch. Calculated by multiplying the LWL area by 5.333 for sea water or 5.2 for fresh water.
Hull Speed Max, knots | 6.43 |
Pounds per Inch Immersion, lbs/inch | 835.79 |
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.
