Heeling in Sailing Boats
In sailing, heeling is a result of the force of wind on the sails. Some heeling is inherent in sailing; as the force of the wind is transferred into forward motion, any excess is transferred into sideways motion, some of which is slippage and some of which is heeling. A boat that has too much sail set so that it heels over beyond a certain angle will sail less efficiently.
When a boat is heeled, the center of effort changes. The center of effort is the pivot point of the sails and is related to the center of lateral resistance, which is below the waterline. One way to reduce heeling is to move the center of lateral resistance upwards by raising the centerboard or daggerboard. The boat will have less resistance below the waterline and consequently less heel.
