Whether it is to test the high seas on around-the-world events in the glory of 49er yachts, to cut through choppy coastal waters on a Lazer racing for Olympic Gold or to set team against team in the great cup challenges, Sail is a celebration of the adventure and skill of one of mankind's oldest sports.

Including chapters on the greatest races and their class divisions and the incredible and inspirational stories of the world's greatest sailors - from Ellen MacArthur to Seve Jarvin, Tony Bullimore to Vinny Lauwers - homage is paid to those who have mastered their boats and set out to conquer the seas.

Sail also includes detailed technical analysis and intricate illustrations on each classification of racing boat, explained by the experts in their field, to give a complete account of the world of sailing competition.
