But in relation to Goodall's comment repeated by Wouter about bow height. I am assuming that this applies directly to spinnaker cats. A-Cats are going the opposite direction ...
Simple have a look at the Hobie Wildcat and you see an A-cat type of nose.
In my opinion, the A-cat designs and Formula boats have started to diverge noticeably about 5 years ago. And I expect this to continue. I don't expect to ever see a modern A-cat bow on a formula boat. Also the freeboard is getting larger and larger on the formula boats.
I can't say that this divergence makes the formula boats less performant so the two classes must be subject to different dominant principles.
