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).

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) Physics of Sailing

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

As a boat speeds up, the wind "shifts" toward the front of the boat. The Sail as a Wing (Lift) If the

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.
