Windsurfing is a spectacular and diversified sport, with different people enjoying different aspects of it. There is light-wind and high-wind sailing. The two kinds of windsurfing involve different techniques and equipment. Light-wind windsurfing, at wind speeds of 10 knots or under, is done on boards that can easily support a surfer's weight while he or she is not moving. This kind of windsurfing is easy, low- energy and relaxing. Cruising This is the simplest form. Setting out for a simple sail across a lake and cruising from point to point is one of windsurfing's most satisfying feeling. Freestyle Freestyle sailing involves putting your board and sail through a series of manoeuvres including turns and sail spins. High-wind windsurfing is done in winds over 10 knots, primarily from 15 to 25 knots. At this speed, surfers can get their boards on to a plane, and the lift created from the board's speed allows for the use of smaller and easily manoeuvred boards. The small boards go faster and require more agility and quicker reflexes. Slalom sailing It is the most popular form of high- wind sailing. When the wind is strong, surfers can be found out on their slalom boards zipping back and forth at speeds of up to 64 kilometres per hour. Bump-and-jump sailing When the wind is strong and the water is choppy, surfers bring out their small boards and the fireworks begin. Bump-and-jump sailing, like slalom sailing, takes place when wind speed is between 20 and 40 knots.
