Dear sam,

I' don't think your reply was fair. I was reading the postings with interest.

One reason for a new rating system could be, that with a calculted formula, you can change your boat (different sails, different number of crew members), report the changes and get a new rating in no time.

Thats the way we doit here in Switzerland when diffrent cat-classes sail together. One race I sailed (distance race), there was a old Shark (~20 feet) (wodden cat with bridge deck) with a huge squaretop main sail and no spin. The guy who sailed it, reported the changes to the rc, got a new rating and made second after correted time.

I think thats fun.
Good sailing!
