...and one more comment to confuse matters. All the boats you listed are spectacular in design and performance, I''m certain.
So there sits a Pearson Triton, fractional rig and all, just to confuse things. Well, not really.
But for the sake of discussion, how would handling change if a Triton (or any of the others you listed) was modified from a fractional to a masthead rig? What sailing characteristic(s) would we notice (mastbend/backstay tensioning excluded)?
