Personally I think attracting people to the sport in general is the bigger challenge. I love the fact that there are a lot of different classes in CRAW. For people who have similar objectives, interests and constraints as I do, I think my particular class sells itself as long as the information is there (let me introduce you to Wouter... :-)).

In terms of the question of getting more people involved in racing catamarans, for me the friendly atmosphere at CRAW has been a big draw. I'm deeply lacking in experience and ability, but have felt very welcome there nonetheless.

But to be more proactive, it might also be interesting to try something like an annual regatta where you have to sail with a crew who has never raced a cat before - as a way of getting the word out.
