No, I think the catagory 2 designation is for the USPN system only and it is intended for the purpose of handicap racing only. This is my point ... you have ONE A Class organization which operates with one set of class rules.

Remember.. USPN's goal is to issue ratings for classes of boats...By USPN tagging a boat as a Cat 2 A class, those owners can register and race the boat in portsmouth easily... otherwise... it's a debate... what rating should we use. An actual class organization may or may not exist ... hell in the case of the CFR 20... The class consists of one boat. hmmm.

Other examples would be in the F18 class.
The Dart Hawk and the Nacra inter 18 were listed in the USPN yardstick with slower PN numbers then the F18 class... yet both were founding boats in the F18 rule. ditto for the Taipan 4.9 w spin and the F16 rating.

USPN follows the public, it does not sanction or control class (or ersatz class rules).
