Sorry yeah, I was talking about the blade.I might be misunderstanding you, but Luna Rossa B1 was the first boat with a skeg. They commented that they'd made the skeg on B2 deeper, not much by the looks of it, and added the thin 'blade' which could be replicated on B1.
The foredeck has a larger radius along the sheerline on B2 v B1. Can't think of many other external hull differences, although there are likely unnoticed ones.
It's all a stretch obviously, but the similarity bt B1 and B2 opens the door to a play which would be incredible to pull off, as far as cup deceptions in plain sight go.
Also, didn't RG indicate yesterday that they also might have lengthened the skeg.
What your suggesting is feasible, but I just don't see it.
Unless AM have already peaked (highly doubtful) I expect them to challenge.
