Boat Speed Calculator

Formula

The formula to calculate the Boat Speed (S) is:

$S = 10.34 \times \left(\frac{\text{WLS}}{\text{WLM}}\right) - 10.34$

Where:

A boat's speed is the velocity at which a boat is traveling based on its waterline while moving and stopping.

Let's assume the following values:

Using the formula:

$S = 10.34 \times \left(\frac{30}{25}\right) - 10.34$

$S = 10.34 \times 1.2 - 10.34 = 12.408 - 10.34 = 2.07 \text{ knots}$

The Boat Speed (S) is 2.07 knots.
