Webb3 sep. 2024 · 1. Maximum "hull speed", in knots, is equal to about 1.3 X the square root of the waterline length of the hull in feet. For example, say you have a displacement hull with a waterline length of 25 feet, then the hull speed is 5 x 1.3 = 7 knots. Trying to propel the boat faster than this will result in enormous increasing power requirements.

Sailormon6 said: Generally, sailboats have displacement hulls, and their speed capabilities are traditionally thought to be limited by their waterline length, but that's not exactly true. Sailboats can, and often do, exceed their theoretical hull speed, especially when sailing off the wind. Webb25 mars 2024 · The formula for calculating the hull speed is Hull Speed = 1.34 x square root of waterline length. For example, a kayak with a waterline length of 16 feet would have a theoretical maximum hull speed of around 6.7 miles per hour. However, a kayak’s actual speed will depend on the previously mentioned factors.
