I don't know what it would take staying within the current rules. I think a design with finer hulls, T foils to overcome the skinny hulls. Maybe moving the rig back a bit?

I do know nothing has been designed as a strictly one up boat for the F16's.

A friend and I were talking about the current generation of bendy mast's on A-Cat's and wondering what could be possible there for the F16's.
