"Second, I have not seen a M-20 (DPN - 57.0) beat a SC22 (56.2) although the dpn's are close. Also, I think the only person sailing a M20 is Robbie Daniel. Also remember that the sc22 is quoted as the carbon comp 22"
Steve, when was the last time you attended a major long distance race? The question would be better stated "When was the last time you saw a SC22 beat the M-20?". Because the SC 22s have all but disappeared from the major long distance races, I can cite the last two match ups. In the last C-100, the M-20 beat a well sailed SC22 boat for boat. In the last Steeplechase the M-20 beat the SC-22 badly, as well as all the other boats.
By today's standards the 450lbs+ SC22 is heavy and outdated. Let's move into the future. The SC22 (ARC22) overcomes inefficiency and mass through brute force and this simply is not necessary. As far as manufacturers certifying to the yet to be established "F-22 Class", I doubt that many outside of Aquarius (ARC/SC builder) will be willing to produce a carbon 22 footer. The market simply does not exist, now that the lightweight 20 (18s?) are showing better performance.
On another note, when was the last time you saw a SC22 beat a well sailed I-20 around a buoy course? Inefficiency and shear size precludes the SC22 from being a successful bouy racer. Who wants to watch sailors struggling around the bouys at paces slower than the M-20 or I-20 for that matter? There is a reason that the most successfull beach cat racing designs have been 20 ft or less (tending towards 18ft).
