I dunno. I'm pretty sure the lack of barriers to entry, inconvenient and costly certification, and safety nannying helped windsurfing get ahead there too. That and dinghy clubs inevitably devolve into race clubs that revolve inexorably around the race safety boat, and if you just want to noodle about or explore you're out of luck unless you are geographically lucky or you can afford a yacht. (which is great. But it's an uncommon privilege)
