We must be talking about different boats entirely.
I don't think so. Reg increased the skeg size from the prototype (see attached) and lowered the transom 1" to remove rocker from the planing section. Modifications were also made to the rear beam pylons and front beam. I think the annapolis tooling was given these modifications as it delayed UK production. The beam sheeted jib was changed to a much larger one that sheeted off the trampoline and the mainsail gained an extra 4" on the leach.
