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.
