Sailing by Romain Sabardeil

When all the yachts in a race are not members of the same class, then a handicap is used to adjust the times of boats. The handicap attempts to specify a "normal" speed for each boat, usually based either on measurements taken of the boat, or on the past record of that kind of boat. Each boat is timed over the specified course. After it has finished, the handicap is used to adjust each boat's finishing time. The results are based on this sum.He must have wind a sail a small boats. They have no leg he guides the boat with the hands.
