What is True Wind Angle?
True Wind Angle is the angle between the true wind direction and the boat's course over the ground. It is different from the apparent wind angle, which is the wind angle perceived on a moving vessel. TWA is used to determine the most efficient sailing angle and to adjust sails accordingly.
