flowing motion of the ocean. Artificial waves created on a designed surface, by water shot over the surface at a high speed to create a wave, are ridden with a short board about the length of a wakeboard. With wakesurfing, which is derived from wakeboarding, it is possible to surf a wave created by a boat without being strapped on to the board and without being towed by a rope. With wakeboarding, the rider is strapped on to the board to prevent the board from flying out under the rider's feet and the rider is towed by a rope without surfing a wave. The "standing wave" or "sheet wave" type of artificial wave was developed in the 1980s by American real estate attorney Tom Lochtefeld who was a partner in the development of Raging Waters water parks in San Dimas, San Jose and Salt Lake City. A surfer from La Jolla, Lochtefeld had a vision of creating water park attractions that were as exciting as riding waves in the ocean, and in 1988 he patented "A wave-forming generator for generating inclined surfaces on a contained body of water." The untechnical, proprietary term is "sheet wave." Rather than pulse a rapidly deteriorating wave of energy through big pools of water, Lochtefeld’s "new wave" flowed water over a stationary surface - in an enclosed, transportable area measured in square feet, not acre feet. The first Wave Loch FlowRider opened at the Schlitterbahn, in Texas in 1991. In 1993, Lochtefeld built a larger, curling FlowBarrel sheet wave at the Summerland resort in Bo, Norway. The first barreling wave pool ever open to the public was developed by Lochtefeld’s Wave House restaurant and music lifestyle centers. The first Wave House opened in Durban, South Africa in 2001, and followed by San Diego, CA (2005), Santiago Chile (2008), and Singapore (2009). WaveLoch company has sold hundreds of FlowRider sheet wave machines around the world - from water parks to Royal Caribbean cruise ships. Dr Peter Killen was the first to develop a continuously breaking, oblique, stationary wave for the study of wave riding. The work was published in the Journal of Fluid Mechanics in 1976.
