125.Windsurfing

Windsurfing, or sailboarding, is a surface water sport using a windsurf board, also commonly called a sailboard, usually two to five meters long and powered by the wind pushing on a sail. The rig is connected to the board by a free-rotating flexible universal joint (U-Joint). Unlike a rudder-steered sailboat, a windsurfer is steered by the tilting and rotating of the mast and sail as well as tilting and carving the board.

A windsurfer holds the world speed record for sailing craft (see below); and, windsurfers can perform jumps, inverted loops, spinning maneuvers, and other "freestyle" moves that cannot be matched by any sailboat. Windsurfers were the first to ride the world's largest waves, such as Jaws on the island of Maui, and, with very few exceptions, it was not until the advent of tow-in surfing that waves of that size became accessible to traditional surfers.

Windsurfing includes speed sailing, slalom, course racing, wave sailing, superX, and freestyle as distinct disciplines.Though windsurfing is possible in winds from near 0 to 50 knots, the ideal planing conditions for most recreational sailors is 15-25 knots, with lighter winds resulting in displacement mode sailing.

Lessons can be taken with a school. With coaching and favorable conditions, the basic skills of sailing, steering, and turning can be learned within a few hours. Competence in the sport and mastery of more advanced maneuvers such as planing, carve gybing (turning downwind at speed), water starting, jumping, and more advanced moves can require lengthy practice.
