True Wind Angle

True Wind Angle is calculated from Measured Wind Speed, Measured Wind Angle and Boat

Speed, this data is then combined with True Wind correction and heel angle correction values

to create True Wind data. True Wind data is used to back-calculate Apparent Wind data as

shown in the vector triangle below.
