I have yet to do this but I hope to someday soon...go to your local bicycle and kayak shops (most kayak shops around here cater to climbers, hikers, and campers too) and post some fliers with action shots of catsailing and advertise a free 'get to know' sailing seminar (like someone posted above). If you get any resistance from the shop owners, explain to them how they can benefit by carrying a few profitable items (some they already do) like life vests, gloves, shoes, hiking harnesses and bring the stuff with you to show them. Only take 10 or so people because these guys will not have boats and your club will have to supply them boats and skippers. Have plenty of pictures and / or videos (see the performance cat promotional video - about 30 minutes of hull flying fun, or excerpts from Rick's stuff) and have a video and chalkboard learning session (borred from the above post) at someone's house on a Friday evening and follow up the next day on the water (and pray the wind shows up too). You might have a contingency for Sunday if it doesn't look very windy for Saturday.

THESE are the people with the money, the drive, and the physical ability to bring this sport back again. They're just off doing other, just as expensive, things. Chances are they just haven't considered that catamaran sailing can be more challenging, a little safer, and a heck of a lot of fun - they've probably never even HEARD of it.

If anyone wants any help designing some marketing materials for such a project, I'll be glad to help for free.
