Re sailing clubs: there'd be about 15 windsurfing members at RQYS, which is the biggest traditional yacht/dinghy club in Bris. Mostly RSX and technos, couple of raceboards. There are also up to half a dozen guys who race raceboards at Paradise Point on the Gold Coast. But definitely the majority of windsurfers are more into the slalom/freeride/social scene. Certainly Simon can give you the good oil on that side of things. Not owning a slalom board and being somewhat antisocial, I couldn't speak with authority on any of that
