To request a rating, complete your profile on the website. You need to provide the requested data. If your boat has not previously been rated, the RC will try to find sources for comparison.
This is an all-volunteer organization. The Rating Committee tries to get ratings completed in a timely manner but it depends on availability of the Committee members.
We know that Flying Fish, Corsair 27 (highly modified!) is signing up for the Figawi and we are supportive of multihull participation in that event (and of course in general).
Let me know if you need further information or if you want to get on a call.
