I competed in a Labor day regatta at the sarasota squadron. They put us on a course shared with a bunch of 420s which was a bit awkward picking through them on the legs, but since they were so slow, it wasn't too difficult.

Same regatta Ryan plowed that little opti kid (on port) with his 6.0 powered up. Dang opti didn't even get damaged, but I heard the 'thunk' 8 boatlengths away.

If this regatta is primarily mutlihulls, then there should be no problems. Lots of setup space and parking, and the race course should be plenty big...
