THE SKILLS OF THE GAME series is perhaps the best known instructional sports series in Britain. Spread across 35 titles, it presents the basics of a subject clearly and accessibly, using the country's leading sports coaches. With photographs, text and diagrams now extensively updated for the 90's, it remains the best value series on the market. Rob Andrews, international sailing coach, here covers not only the techniques of dinghy sailing, but also provides a helpful guide to the different types of boat and equipment. He also offers advice on the mental approach to improving your sailing. AUTHOR: Rob Andrews was coach to Britain's 1992 Olympic sailing team, and remains a top international coach. 100 photos
