PORT CALCULATOR
Hull Speed Calculator
Calculate your boat’s hull speed to optimize performance on the water.
What is the Hull Speed Calculator & How does it work?
A boat’s hull speed is a critical factor in determining its efficiency and performance. It represents the maximum speed a displacement hull can achieve, which is influenced by its length and design.
The formula for calculating hull speed is based on the wavelength of the wave created by the boat’s motion through the water. The hull speed increases with the square root of the waterline length, making longer boats inherently faster than shorter ones under similar conditions.
\text{Hull Speed} = 1.34 \times \sqrt{LWL}\
LWL = Waterline Length (in feet)
