Velocity Made Good (VMG) Calculator

Calculate VMG



Formula

The formula to calculate the Velocity Made Good (VMG) is:

\[ VMG = BS \times \cos(TWA) \]

What is Velocity Made Good?

Velocity Made Good (VMG) is a measure used in sailing to indicate the speed at which a boat is moving towards its intended destination or waypoint. It is the component of the boat's speed that is in the direction of the waypoint. VMG is particularly important in racing and navigation, as it helps sailors determine the most efficient course to achieve the highest speed towards the destination, considering the wind direction.

Example Calculation

Let's assume the following values:

Using the formula:

\[ VMG = 10 \times \cos(45^\circ) \approx 7.07 \text{ knots} \]

The Velocity Made Good (VMG) is approximately 7.07 knots.
