For most sailors, boat tuning may seem a mystery understood only by sailmakers and the like. In this book, sailor, chandler and championship winner, Ian Pinnell, unravels this daunting subject and will help improve your boatspeed as a result. Since most races are won or lost by a difference of less than 2% of racing time, you will soon be moving up the fleet. With hundreds of photos and diagrams to illustrate every point, the book clearly explains what each control does and how to set it up optimally for different conditions. Additional troubleshooting and skills sections take things even further, making this the bible of dinghy tuning.

Ian Pinnell has been winning sailing championships since the early 1980s and is continuing to do so over 30 years later. He has over 40 World, European and National Championship titles to his name in classes as diverse as the Enterprise, 505 and Mumm 30. He is Managing Director of Pinnell& Bax, one of the UK's leading sailmakers and chandlers.
