How Sails Work or How Sailboats Sail into the Wind

Traditional sailboats can only sail with the wind behind them. But modern sailboats have sail designs that enable them to sail in any direction regardless of the wind. Except for the “no-go” zone which is about 45 degrees on either side of the wind, where it’s physically impossible to create lift no matter how to angle the sail, in which case the sailor can simply zig-zag in the direction he or she wants to go. The secret to these sail is lift. The very same force that enables airplanes to fly in the air. In fact the same concepts apply, Newton’s 3rd Law, Coanda Effect, Bernoulli’s principle, anything that applies to wings apply to sails as well.
