Tim, I'd direct your attention to the "what have you done for sailing lately?" thread.

Lots of gems in there. The easiest is to just have interested folk hop on your boat for a quick ride or two. Then they can see for themselves it's not rocket science, it's fun, and you can send them on to your local club or dealer...

Speaking of dealers, I'm sure they'd be happy if you offered to take some of their curious customers out for a ride when you are available. With the exception of a few, many dealers don't have inventory sitting around rigged to sail.

Hope it helps.
