...there are now sufficient true F16s that don't need to include new ones under the "grandfather" rules.
I couldn't agree more. It is just not fair to John P or Phill or one-off builders who have built true F16s to let Cirrus in with a longer boat with a bigger rig--heck, they're were no doubt aware of the formula but not interested. I'm happy to sail with them anytime, just as with the I17s or Fx-1, but it isn't right to allow grandfathering in a new design now that the rules are in place. It goes contrary to the spirit or intent of the rule.
