Display system to indicate sailing data of a small size boat
摘要:
A display system for indicating sailing data to an operator of a small sized sailing boat in which a speed sensor in the hull transmits pulses to a speed measuring device which stores the data in a memory. The sailing data is periodically transmitted to a receiver worn by the boat operator either on his wrist or some conveniently viewable position.
