I just contacted Sail America, the top-level organizer for most of these shows.
It's $250 with unlimited floor space for a Class Association, (such as Tornado, A-Class, Hobie, etc) and their boat, either on land or in the water - a GREAT deal. For a non-profit group, it's $1.00 per square foot - 1/6th of the normal rate. Or $100 for a booth (normally $825) plus a yearly membership fee of $50. (This is not supposed to be published info, so let's try to keep this on these web pages only!).
Right now there is room at Atlantic City Sail Expo. If NAMSA pays the bill and my tolls/gas/hotel - I'll volunteer my time, bring my boat there, be the booth attendant etc. I'd like some help with promotional stuff to hand out, PC's with mpegs running, etc - any other volunteers?

Is there a catamaran organization, fleet, or whatever willing to sponsor me for this? I think we (cat sailors) need to do something.
