Windsurfer PatentIn 1968, a patent application was filed for a “Wind-Propelled Apparatus” by Jim Drake and Hoyle Schweitzer. When issued as No. 3,487,800 on 6 Jan 1970, it was the first U.S. patent for the Windsurfer sailboard: a surf-board with a sail on a mast articulated by a universal joint to the board. The rider can thus hold the boom and adjust the angle of the sail to control acceleration, turning and tacking, without need of a rudder or steering mechanism. The rider uses skill to moderate the propulsive power of the wind by manipulating the sail while keeping balanced on the craft. Drake was an aeronautical designer, and Schweitzer was a businessman and surfing enthusiast. Their British patent GB 1258317 was later revoked due to evidence in court of similar prior art presented by earlier innovators who did not patent.« |
