Thom,
Those are my feelings exactly. Personnally I am not looking at excluding the sc22. I would rather have a hybrid boat develope. But, I believe that the builder of the boat will probably want to stay with its existing one design setup.
There are two other designs that are coming forward that as of yet are "paper-only" and untested but, promise better performance.
From a organizers perspective let everything that qualifies run and let the race course decide which is the better performer.
As to the desicision process that is up to the PRO and circuit chairman. Of those two postions I am neither.
