WebOct 27, 2016 · We use true wind angle because apparent wind angle (AWA) changes wildly with relatively small changes in true wind speed. In six knots of breeze at 140 TWA, the apparent wind angle might well be around 90; at 10 knots, it might be at 120 AWA. The AWA is also a function of boat speed: Light, fast boats pull their apparent wind much further ... WebSailing close to the wind uses the shape of the sails to generate lift. To flow around the sails, the wind has to deviate in direction, as shown by the arrows for initial velocity vi and final velocity vf, which are given with respect to the boat.
