THAT was a long time, a typo or one of the pioneers with Randle tests ?
As I recall the first public accessible kitefoil, Carafino, was in 2007 around the world, and Laird/Dave foiled on waves in 2006.
Rush Randle did his work and test of kitefoils in early 2000s though, so maybe he was using these - indeed a pioneer then
Even the Flying Moth Dinghy didnt came untill 2009 (they fly around out here too now)
Or was it the AirChair he was into, as it came in the 90s, very early
