hull speed calculator

Hull speed calculator is a simple calculator that determines a vessel's hull speed based on the length of the vessel's waterline.

11 aug. 2025 — Work out the maximum displacement hull speed from the waterline length (LWL), or find the LWL required for a target hull speed. LWL units can be ...

Calculate your boat's theoretical hull speed and determine displacement characteristics. Essential for marine design and performance analysis.

The below given is the online Hull speed calculator which you can use it for the boat displacement speed calculation with ease.

Theoretical displacement hull speed is calculated by the formula: velocity in knots = 1.35 x the square root of the waterline length in feet.

Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel.

Calculate a vessel speed based on the available horsepower. Calculate the horsepower required for a desired speed. What it won't do. No calculations for ...

Hull speed can be expressed as a simple mathematical formula 1.34 X the square root of the length of the waterline (HS = 1.34 x √LWL). For instance, if a ...
