TIL,
That is interesting about CRAM. Back in the 1980's when we were racing a Hobie 18 in Division 10, I know Division 10 sailors went to several CRAM regattas every year, and we had the CRAM events listed on our Division schedule.

But just recently I asked a Hobie sailor up there why they do not join CRAM now, and he told me Hobie sailors get negative vibes from the CRAM sailors, like disparaging comments about Hobies, and pressure to get a different kind of boat.
