"AHPC and the Tool", I stand corrected there.
I know Melvin did the Inter-18 but the Nacra F18 is by Comyn (spelling ?). Melvin also did the Nacra A2 but wasn't that a single event wonder ? Sanguiet back in 2006 or so where there was lots of light patchy winds ? I remember discussing this with you actually.
But yeah, Melvin would could be the answer to the question if a designer exist who was succesful in both classes. I grant you that. Although, I don't think two boats can be more different from oneanother then the Inter-18 and the Nacra A2. How does one even start comparing those two bow shapes to each other ? This would again bite us back in the tail with respect to how this whole discussion started.
