High on the beat. Low on the Run. Fast on the reach. Performance starts with your sails: you simply cannot win unless they?re right. This book shows you how to develop sails that match your rig. There are sections on how sails work and how to trim them on every point of sailing. A faultfinder chapter shows how to cure all the common problems, and a section on asymmetrics shows how to handle this new breed of kite.
