WebThe formula for this ratio is: ballast displacement ratio = ballast / displacement. In other words, it tells you what percentage of the sailboat's weight is in the ballast. The average value is between 0.35 and 0.45 for cruising boats. This means that on average, 35-45% of the weight of a cruising boat will be carried in the keel ballast. WebForces on a moving sailboat. (a) Sail and keel produce horizontal “lift” forces due to pressure differences from different wind and water speeds, respectively, on opposite surfaces. (b) The vector sum of lift forces from sail and keel forces determines the boat’s direction of motion (assuming there’s no rudder). classicware https://bayareapaintntile.net
