they will have to FREEZE development at some point.
Sorry Scooby, that is an assumption.
Plenty of development in the 49er, Star, 470 and Tornado OD classes. Even the Laser class has undergone some chages. The only difference here is that all these classes are competing against themself and not involved with any formula racing.
Why not start with a clean sheet and stay away from the F18 class. Surley that has to be more healthy for the sport.
