Hey, we dont need to call it F-20 something if the B-class rules are resurrected, it just happens to be the B-class

I tried to find the last revision of the B-class rules, but was unable to find them. I did browse trough the A-class rules tough, and they seem very sensible and easy to adapt.

Some boat data:

Taipan 5.7, not a 20 foter, and not 10 feet wide either in it's original form, but a very potent platform. Macca widened it to 10 feet, put a carbon mast on it with a selftacker and feels pretty competitive. Out of production tough

Any others?


Perhaps it would be a good idea to consult with some designers what a sensible minimum weight should be for now, and allow designs below the limit to use correctors?
