Trey - if it's only 16's, then it could be an HCA event. You can get free regatta insurance (see the HCA-NA.org website for details).

Contact Nora at Hobie Cat (nora(at)hobieco.com), let her know about how many boats will be there & she'll send you a box of swag to hand out.

If you want, I can send you a box of Hotlines, too.
