I did some sail racing, Lasers to 470s and hobie 14's.
Windsurfed as far as the big board small sail stage.
Waterskied all the variations from kneeboard, disc, double, single, trick, wakeboard, surfboard (we used to call it skurfing), home-made boards.
Flew 4 x Flexifoil 10 foot stackers with a harness on the beach.
Kiting just brought all that together for me.
I have a race board coming soon, which takes a lot from windsurfing board design, and I think now that kite racing will bring all that background together into something great.
