Mike Murphy “Hydrofoil Kneeboard”
Lake Sammamish, WA. 1985
Mike Murphy and Bob Wooley co-invented the hydrofoil kneeboard in 1985 and sold it to Kransco, the maker of Hoola Hoop and Hydroslide. This design was the inspiration that lead to their co-invention of the sit down hydrofoil (Air Chair) in 1989.
