Curious - we were talking about it here locally, but did not know...
Today one guy, James, did some really fast runs in 18-20 knots or so, reaching 41,7 knots (77.3 km/h) in 2 seconds, and 38.4 knots (71.1 km/h) in 10 seconds, I find it amazing but have no idea how other fast riders are doing ?
Myself I ride only half the speed when fast, ha haa - not into speed but love the challenge and to follow whats possible
Speedboards and windsurfers ride in a lot more wind when fast, riding WITH the wind, not as efficient and a totally different ballgame, inefficient
How fast are the fast ones, kitehydrofoiling ?
