I got a suggestion.
How about a section on this forum for beginners? It could have links to windsurfing instructions etc.
Maybe the more 'experienced' sailors with old stuff clogging their garages could offer their clapped out clobber for beginners to use for free. Like a library system. I know 'free' is a painful word in WA but look at is as an investment. The more sailors, the more shops, the cheaper the prices.
And before we all get on our high horses about 'you need to start on the right stuff!', I reckon that's a load of rubbish.
I wonder what kind of kit Robbie Naish started on?
No matter what you sail, you'll learn something!
I gave an old board/boom/mast and sails to a guy in work and he's now well on his way, heading to the nearest windsurf shop with a big fat wallet cos he's caught the bug. He's passing the old kit onto another friend now, since he grew out of it in a matter of weeks.
Just an Idea..
