How do you calculate a boat's righting moment?

To calculate a boat's righting moment, you need to determine the boat's center of gravity (G) and the center of buoyancy (B). The righting moment is calculated by multiplying the distance (known as the "righting arm") between these two points (the vertical distance from G to the waterline, perpendicular to the heeling angle) by the weight of the boat. This can be expressed mathematically as ( \text{Righting Moment} = \text{Weight} \times \text{Righting Arm} ). Accurate measurements of the boat's weight and the heeling angle are essential for precise calculations.
