I agree with whoever was saying about how kids have to depend on their parents.
I started sailing when i was about 6 or 7 I think, I sailed competitively until about 2 years ago. I started windsurfing about 5 years ago with my brother, for something a little more exciting.
My parents both had no interest in windsurfing, we had to scrounge the money together to pay for a setup out of the quokka. We both ended up with Bombora's and Dacron sails, horribly difficult equipment to learn on. If we didn't have a large knowledge of the wind through sailing, I don't think we would have stuck at it.
We were lucky enough to be able to store our gear at the yacht club we sailed at, and sometimes if i was really keen i would ride down there to go windsurfing. We could only really get into it when my brother got his license.
These days I see kids who have all the latest gear, and get to go to all the best spots (Matt Gwynn (Safety Bay) is a very good example of this) and because their parents/ dad are madly into it, they get madly into it and get all the best stuff.
Matty kicked my ass in the lano wave comp, and it makes me think how good i could be now if my dad was a windsurfer and took me everywhere

Moral of the story, get your kids into it because they get their friends into it!! Thats the only way this sport can grow i reckon cos kids are too lazy to tow stuff down to the beach/ river.
Also, whoever asked the question, Schools do have windsurfing (some) as part of their curriculum. I run the windsurfing part of WA Surf, and I tow the trailer up from safety bay during the week to teach All Saints and Aquinas, and I am currently trying to get more schools. It is a good market to crack into and I can see there are a few who are interested and want to keep going with windsurfing, which is great!
