Windxtasy,one of the reasons theres more guys on the water that have no idea on kites rather than windsurfers is its too easy to learn how to get up and going. Windsurfers definately do an apprenticeship. Windsurfing was the most frustrating thing I ever got competent at. As I learnt slowly, I got tips from the crew but was so crap I was a danger to no-one. 1-2 lessons and most guys think they can do the rest themselves with the help of their mates. All that important stuff on consideration of other water users is missing.
If Im heading on an opposite tack to a windsurfer, regardless of port or starboard, I go downwind of them, keep my kite low and gesture to them to go upwind. Being an ex-windsurfer, I know its so hard to get the rush. Wrong sail, wrong board, and what a bugger to learn.
We are on more efficient gear, powered all the time, can smoke a windsurfer on an upward tack. Have the speed record, can ride waves, rails, jump piers, AHH its great being a kitesurfer
