The NAHCA is just that, it represents one-design racing, with an almost simplistic view. Anyone can buy a used hobie an race it. No need to buy the latest and greatest sails and rigging. Just hop on and have fun. That is what's kept the Hobie scene alive over the years and it will continue to do so. (I should not forget to mention it's the people too)
I think the NAHCA and an umbrella catamaran association can coincide. Afterall, they just have two different views, right? What's so bad about that? I don't see the need to bash an organazation that has been succesful over the years, not to mention, also puts on events both on a National level and a local level every year.
