For availability, that would have to be worked out with Aquarius, but if a new boat is designed the availability issue doesn't go away. I would think it would be easier to get more boats from Aquarius than to ramp up a new production line. The SC-22 is a powerful boat - I would say that the thing to do, either with the 22 or any new spec boat is to provide for either a way to reef the main or have an optional reduced size main for heavy air. Alternatively, I'm sure Bill Roberts would work with you to design a "more reasonable" rig for a spec series - still a better route than to design from scratch.
The 22 in our Fleet has seen lots of different conditions, it's even seen a micro-burst on the beach before the C-100 2 years back (hit by a flying 5.8 if I remember right), no broken mast... It is a fast and serious boat, but not out of control from what I've seen.
I think the 22 would be a great boat for a spec pro series capable of drawing sponsorship and viewer interest. Just my guess...
