Windsurfing is a surface water sport using a windsurf board, also commonly called a sailboard, usually two to five meters long and powered by a single sail. The rig is connected to the board by a free-rotating flexible joint called the 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.

The sport combines aspects of both sailing and surfing, along with certain athletic aspects shared with other board sports like skateboarding, snowboarding, waterskiing, and wakeboarding. Although it might be considered a minimalistic version of a sailboat, a windsurfer offers experiences that are outside the scope of any other sailing craft design. 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 surfers.

Windsurfing includes speed sailing, slalom, course racing and freestyle as distinct disciplines.

Though windsurfing is possible in winds from near 0 to 50 kts, the ideal conditions for planing are 15-25 kts, 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, gybing (turning downwind at speed), tacking (turning upwind), jumping, and more advanced moves can require lengthy practice.



Different courts in different jurisdictions have recognized different inventors, clouding any possibility of clear attribution. However, what is clear from the historical record is that windsurfing, as it is known today, owes much if not all to the promotion and marketing activities of Hoyle and Diana Schweitzer, In 1968, in Southern California, they founded the company Windsurfing International to manufacture, promote and license a windsurfer design. Together with Jim Drake, an aerospace engineer, they were the holders of the very first windsurfing patent ever, which was granted by the USPTO in 1970, after being filed in 1968. They also originated the term "Windsurfer," which was registered to them as a trademark by the USPTO in 1973.

The Drake and Schweitzer creation was a surfboard-like board with a triangular "bermuda" sail and wishbone booms, connected to the board via a universal joint. The details of the original designs are available in Drake's whitepaper on windsurfing. Also, the history of the invention is discussed in these interviews with Jim Drake. Despite forty years of subsequent development, this apparatus is remarkably similar to windsurfing equipment in use today, and the word which Drake and Schweitzer coined to describe their invention has become eponymous with the sport itself. There is no evidence that they had knowledge of any prior inventions similar to theirs.

Drake relinquished his patent rights to Schweitzer in 1973. Through the seventies, Schweitzer aggressively promoted and licensed his design to manufacturers worldwide, and the sport underwent very rapid growth in Europe. At the same time, Schweitzer also sought to defend his patent rights vigorously against unauthorized manufacturers. This led to a host of pre-dating windsurfer-like devices being presented to courts around the world by companies disputing Windsurfing International's rights to the invention.

Schweitzer sued Tabur Marine, the precursor of Bicsport, which is still a major manufacturer of sailboards and other marine recreation equipment today. In Windsurfing International Inc. v Tabur Marine (GB) Ltd. 1985 RPC 59, British courts recognized prior art by Peter Chilvers, who as a young boy on Hayling Island on the south coast of England, assembled his first board combined with a sail, in 1958. Intended to be steered by a rudder, it did not incorporate the curved wishbone booms of the modern windsurfer, but rather a "straight split boom". The courts found that the Schweitzer windsurfer boom was "merely an obvious extension". It is worthy of note that this court case set a significant precedent for patent law in the United Kingdom, in terms of Inventive step and non-obviousness; the court upheld the defendant's claim that the Schweitzer patent was invalid, based on film footage of Chilvers.

In 1983, Schweitzer sued Swiss board manufacturer Mistral, which also continues as a major manufacturer of sailboards. However Schweitzer lost the case. The Mistral defense hinged on the work of US inventor Newman Darby, who in the mid-sixties conceived the "sailboard." a hand-held square rigged "Kite" sail on a floating platform for recreational use. Darby's published version did not show any connection between the rig and the board (the mast simply rested in a depression on the board) but it did refer to a "more complex swivel step for advanced riders not shown". He published his "sailboard" design in August 1965 Popular Science magazine. Darby organized Darby Industries, Inc. in 1964 to build what they called sailboards. However, the "sailboard" never gained popularity, and Darby's company ceased operations by the end of the sixties.

Eventually US courts recognized the Schweitzer windsurfer as an obvious step from Darby's prior art. Schweitzer had to reapply for a patent under severely limited terms, and finally it expired in 1987. Shortly thereafter, having lost its license royalty income, Windsurfing International ceased operations.

For their part, Australian courts, in a 1983 patent case reported in "Intellectual Property Reports" 3 IPR 449, attributed the first legally accepted use to an Australian boy, Richard Eastaugh. Between the ages of ten and thirteen, from 1946 to 1949, aided by his younger brothers, he built around 20 galavanised iron canoes and hill trolleys which he equipped with sails with spilt bamboo booms. He sailed these near his home on the Swan River in Perth. There is no evidence that any of the later "inventors" ever sighted the Eastaugh craft of a decade earlier on the other side of the world.

It is acknowledged that the Eastaugh, Chilvers, and Darby inventions all pre-dated the Drake and Schweitzer invention. However, the popularization of windsurfing would not have taken place without the efforts of Schweitzer. The prior inventions simply lay forgotten until they re-emerged in legal defenses against litigation by Schweitzer.
