Sail trim is the art of setting sails in response to the varying conditions imposed by the wind, waves, boat speed and desired course. Regarded as something of a black art, good sail trim can mean the difference between winning and losing a race or reaching harbour before the tide turns. This book demonstrates the skill of good sail trim with the aid of superb colour diagrams and photographs, to enable racers and cruisers alike to sail efficiently and get the most out of their boats. Taking account of all types of wind condition the author explains: - aero and hydrodynamics - rig types - the best way to rig a vessel - sail cloth and cut - the right trim for mainsail and smaller sails - sailing before the wind There is really only one way to set your sails for maximum efficiency; this book explains how.
