Theoretical hull speed formula

WebbYou calculate the maximum hull speed (HS) by taking the length in feet (lwl), get the square root, and multiplying it by 1.34. HS = √ lwl * 1.34 HS = Hull Speed lwl = length at waterline So a 80 feet boat has a maximum hull speed of: √ 80 * 1.34 = 12 knots Sailboat Length and Hull Speed (Longer = Faster) Watch on Exceeding Hull Speed WebbThe theoretical hull speed of a boat is the maximum speed it can travel without surfing, it is commonly calculated by the formula 1.34 x ?LWL, where LWL is the waterline length in feet. For example, a boat with a 20-foot waterline length would have a hull speed of 6 knots, and a boat with a 40-foot waterline would have a hull speed of 8.5 knots.
