This tool calculates your boat’s hull speed based on its waterline length.
Hull speed is the speed at which the wavelength of the bow wave of a boat is equal to the boat’s waterline length. It is often used as a measure of the speed potential of a displacement hull. This calculator uses the formula:
Hull Speed (knots) = 1.34 * sqrt(Length of Waterline)
To use this calculator, enter the length of the waterline of your boat in the text field and select the desired unit for the hull speed result. Then click the “Calculate” button to compute the hull speed.
How it works:
- Length of Waterline (ft): Enter the length of the boat’s waterline in feet.
- Choose Units: Select the unit for the output speed (Knots, Miles per hour, or Kilometers per hour).
Limitations:
- This calculator assumes the hull is a simple displacement hull and does not account for other hull designs.
- Water conditions, hull shape, and weight distribution can affect actual hull speed.
