That's a good question. Probably the best way is to contact the multihull association closest to you. There are several associations around the country for the bigger multihulls; e.g., Multihull Association of South Florida (MASF), Florida Offshore Multihull Association (FOMA); New England Multihull Association (NEMA); Chesapeake Cruising Multihull Association (CCMA); Lake Erie Multihulls (LEM). And there are similar associations on the West Coast. All of them have a racing schedule.
You can also contact the class associations for Corsair and Farrier trimarans.
You can find contact information for most of these organizations in the extensive list of multihull associations at
www.ussailing.org/multihull. I don't know how up-to-date the information is, though, so if that doesn't work, I would suggest that you contact Multihulls Magazine. I'm sure they have contact information for all the big-multihull organizations. MM's phone is 617-328-8181 and their e-mail is [email]multimag@aol.com.[/email] Website:
www.multihullsmag.comI know any of the multihull associations would welcome you, because there are always boats that need crew.
