Essential for any high performance sailors

Frank Bethwaite has been at the leading edge of national and world class sailing for over sixty years. Apart from his own outstanding racing successes, he has coached every level of would-be champion from basic to Olympic standard. Within his own family, three are Olympic champions and three are world champions in four classes. From a background of aeronautical engineering and meteorology, Frank spent thirty years in military and civilian aviation and finally in scientific flying. When he retired he decided to find out how small sailboats worked - so that he could make them sail faster.
