Sailing Theory
The sum of all wind pressure on the sail is called wind force. The center of that force, which is above the water, is called the center of effort (CE). The center of the force below the surface of the water is calledthe center of lateral resistance (CLR). This is the point where all the boat's resistance to sideways pressure is concentrated. A boat performs best when the two forces are in balance. |
