My vote is if we get 10 or more F18s then we should race as our own fleet. It is our mid-winters and we should be scored as our own fleet. Also, I'm not sure if a separate start is required for the race to count for our class rankings (Ding - any idea?).
No problem with that at all. A large fleet of Formula/OD that is hosting a Midtwinters/Nats/Continetnals has that right. It may very well be mandated by the NAF18 group.
My thinking is that if you want to race with the F18s then get an F18.
I'd lose too many sailing days when I do not have a crew ready to go. I do not have the luxury of having dependable crew. My problem, not yours.
One problem with clumping boats of different speeds into a single start is that you may have fewer starts, but you end up waiting longer for everyone to finish.
The speed differences of the boats in question are not very large. Ok, I'll really shut up now.
