"This book starts off with a step-by-step guide to setting up fractional and masthead rigs - checking the fittings, putting the mast in the right place and assembling the standing rigging.  Then, it's time to go sailing and get down to some serious tuning.  The author looks at the rig controls, and shows how to adjust them for the condition of the moment.  With the rig set up, he turns his attention to the sails, and explains how to trim them for maximum efficiency on every point of sailing.  He shows you the sail shape to aim at, why it works, and how to achieve it.  In short, how to make your boat the fastest on the water.  63 Pages."^^<http://www.w3.org/2001/XMLSchema#string>
