Physics Of Sailing -

Most people think sails work like parachutes, with the wind pushing the boat from behind. While true when sailing directly downwind, most sailing relies on .

For a boat to be balanced, the "push" from the sails (Center of Effort) must align correctly with the "pivot" of the keel (Center of Lateral Resistance). Physics of Sailing

This is the wind the boat actually "feels." It is a combination of the (what you feel standing still) and the Induced Wind (created by the boat’s own movement). Most people think sails work like parachutes, with

Sailing is essentially a game of "aerodynamic tug-of-war" between the air above the water and the water below it. 1. The Sail as a Wing (Lift) This is the wind the boat actually "feels

Like an airplane wing, a curved sail creates a pressure difference. Air travels faster over the "outer" (leeward) curve of the sail, creating low pressure. Higher pressure on the inside pushes the sail toward that low-pressure zone.

If the sail creates a sideways force, why doesn’t the boat just slide sideways? The answer is the (or centerboard) under the boat.
