Theo - I DO have a boat policy with the company that drives those white trucks with blue lettering. I don't know who you talked to, but the auto division may not know what you're talking about. To them, a "high performance catamaran" may mean those offshore racing powerboats.

Best bet is to contact (or ask for) their marine underwriting agent. Tell them your boat is similar to a hobie cat (I told them mine was like a "hobie on steroids"), and they should get the idea. Problem is that few sailors get insurance for beachcats, so some agents are unfamiliar with what you're asking for...

PS - are you the same THEO from that other site where oodles of smack and rudder rake settings are discussed? If so, we can talk if you make it to St. Augustine for the Sizzler weekend in July... I'll try to get contact info for my agent...
