As a racing sailor on everything from J/22's to 55 ft. keelboats and a student of sailboat racing in general, I have read just about everything published on the subject. As a clear, concise, easily read and to-the-point reference, Winning Races is hard to beat and remains the one book I regularly turn to before a regatta to refresh my memory. In economical and easily understood phrases, Mr Heyes takes the reader through all the stages of a successful keelboat racing campaign - from preparation of the boat, through sail trim in all conditions, to crew work and tactics. The information presented includes tips basic enough to make a difference for the begining PHRF racer and others complex enough to teach an experienced international racer a trick or two. More importantly, Mr Heyes' comments are equally applicable to boats large and small, masthead or fractional rigged - which is often a shortcomming of other books on the subject. If you race, want to improve your performance and only want to read one book - this is the one.
