Ice Windsurfing On A Frozen Lake

Windsurfing, as a sport and recreational activity, did not emerge until the latter half of the 20th century. But before this, there have been sailing boats of various designs that have used wind as the driving force for millennia, and Polynesians have been riding waves for many of them, undertaking day trips over oceans standing upright on a solid board with a vertical sail.
In 1948, 20-year old Newman Darby was the first to conceive the idea of using a handheld sail and rig mounted on a universal joint so that he could control his small catamaran—the first rudderless sailboard ever built that allowed a person to steer by shifting his or her weight in order to tilt the sail fore and aft. Darby did not file a patent for the sailboard. However, he is widely recognized as its inventor as well as the first to conceive, design, and build a sailboard with a universal joint. In his own words, Darby experimented throughout much of the 1950s and 1960s and it wasn't until 1963 that an improved sailboard with a conventional stayed sloop rig sail arrangement made it more stable than the one built in 1948. In 1964, Darby began selling his sailboards.
12-year old Peter Chilvers is often cited for inventing a sailboard in 1958. In the 1960s, Jim Drake was the first to solve many problems of getting the board to sail while Hoyle Schweitzer was the first to be successful in marketing the sailboard.
In 1964, during a discussion on water sports over a brandy at his home in Southern California, RAND Corporation aeronautical engineer Jim Drake and his former Rockwell boss and now good friend Fred Payne, who worked at The Pentagon, discussed options for creating a wind-powered water-ski which would allow Payne to travel on the Potomac River. That night they developed the idea of a kite powered surfboard. On later reflection, Drake didn't like the integrity of the idea and dismissed it. There were already a number of sailboard designs available, and Drake also was concerned about the integrity of a design needing taut wire close to a human body to keep the sail upright.
