Abstract
A system for evaluating the performance of a sailing boat wherein average boat speed, average apparent wind speed and average apparent wind direction are sensed and are utilized to determine the performance characteristics of sailing boats. The system includes an apparent wind direction indicator which senses the instantaneous apparent wind direction and compares it with a previously generated average apparent wind direction signal to obtain an error signal. The error signal is intergrated to obtain an average error signal which is utilized to correct the previously generated average apparent wind direction signal by changing the position of an average apparent wind direction indicator.
