How do I calculate the weight of ballast for my boat?

To calculate the weight of ballast for your boat, first determine the boat's total weight and the desired center of gravity. A common rule of thumb is to add ballast equal to 10-15% of the boat’s weight for stability. You can also use the formula: Ballast Weight = (Total Weight x Desired Stability Factor) - Current Weight. Ensure that the ballast is distributed evenly to maintain balance and safety while sailing.
