A wing is a handheld inflatable sail that is used to generate wind propulsion. The invention of wing surfing is dated back to 1981, when aeronautical engineer Jim Drake, the inventor of windsurfing, and Uli Stanciu, European windsurfing pioneer, invented the first wing. Their patented concept was based on the symmetrical shape of the flying fish. Unlike windsurfing, their wing was hand held and not fixed to the board via a mast.
