Theoretical hull speed calculator

Webb15 jan. 2024 · The calculation for the theoretical hull speed (in knots) of a non-planing (displacement) boat is the square root of the waterline length (in metres), multiplied by 2.43. Keel percentage. Keel percentage says something about stability – but not everything. Webb26 okt. 2002 · Hull speed = SQRT(LWL)*1.34 This is the theoretical hull speed for a displacement hull (most sailboats). It is a function of the length of the wave created by the boat as it moves through the water. Wave speed is a function of wavelength; longer wavelengths are faster. Longer boats make longer waves.
