Jake,
That was not part of the "edict," but it has always been the case, as far as I know, that Hobie fleets are only for Hobie sailors. That is why a number of fleets have converted to multiple-class, umbrella organizations, like CABB in the Miami area and TBCS in the Tampa Bay area -- so they could be more inclusive.

Our Hobie Fleet 36 is a part of CABB, but right now it only has two or three members, whereas CABB includes a large assortment of boats.
