My young bloke is fairly keen, but far from "next star" status, since he is only 9. Will keep pushing...gently

Fingers crossed.
I'm in the same boat Aus1111. My young fella (10) had his first go at windsurfing a few months back. I asked him what he thought of it, and the word "Awesome!" was the reply

Back into again this spring. Hopefully he will inspire some of his mates. KA360 is leading nicely by example.
As for future champs, who knows. So long as some kids take it up and have fun, that's good enough for me.
Here's some footage of my young fella Ryan and a friend, Tyler, with their first go at windsurfing.
