This beautifully illustrated and well-organised book shows you how to trim your sails and rig for maximum performance.

With a revolutionary approach to sail and rig tuning, this book tackles the practical and realistic elements of tuning your boat as well as the theory of sail aerodynamics. The book covers the many variations in boat, sail and rig design. It has become the bible on tuning.

"... this book is different. It's stuffed with over 150 clear colour illustrations and informative captions and explanations. I recommend this little book to everyone - whether expert or novice, you'll find something." Sailing Today

“Over 80 pages this book goes from the basics of points of sail, sail-shaping tools, twist and apparent wind, right through to setting the spinnaker pole height and moving the spinnaker sheet lead forward to reduce the tendency to roll downwind. There’s also a very handy problem-cause-solution section which gives you things to try if you have too much weather helm, or you’re not pointing as well as you should.” Yachting Monthly
