When towed at speed, by a powerful boat or some other device, the board of the hydrofoil 'flies' above the water surface and generally avoids contact with it, so the ride is largely unaffected by the wake or chop of the water and is relatively smooth. The air board is a modified hydrofoil where the skier stands up. ==History== Hydrofoils date back the early 1900s, however they were not part of a recreational sport. While the first hydrofoil boat was created in 1906 by Italian inventor Enrico Forlanini,〔(【引用サイトリンク】title=History of Hydrofoiling )〕 the first waterski hydrofoil was invented in the early 1960s by Walter Woodward, an aeronautical engineer, with two skis attached to a bi-wing hydrofoil.〔(【引用サイトリンク】title=Hydrofoiling History )〕 In 1972, Mike Murphy and Bob Holst added a bi-wing hydrofoil to a surfing kneeboard, then reduced the bi-wing to a single wing.〔 Murphy and Bob Woolley then applied the concept to sit-down hydrofoil, with Woolley riding the first "Sit Ski" in 1984.〔 After various material changes, including the addition of a seat belt to keep rider and ride together and prevent separation collisions, they sold their first "Air Chair" in 1990.〔 Advancements in materials and hydrofoil design have created stronger rigs, gentler rides (shock absorbers in the seat), more maneuverability, and boards that combine sit-down and stand-up (air board) for surfing.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sit-down hydrofoil」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
