For most sailors, boat tuning may seem a mystery understood only by sailmakers & the like. In this book, sailor, chandler & championship winner, Ian Pinnell, unravels this daunting subject & 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 & diagrams to illustrate every point, the book clearly explains what each control does & how to set it up optimally for different conditions. Additional troubleshooting & skills sections take things even further, making this the bible of dinghy tuning.
