Once you're flying the main hull, any more sail area is just parasitic drag. Given that the Mod 70 was semi-foiling on the leeward ama, it's a pretty good demonstration that size doesn't matter, once you're on the foils. Yes, in rough water the 70 is going to march away, but in the smooth water of the Great Sound, it doesn't seem that there would be a big speed advantage to bigger boats in the AC...it's just that the crashes won't be as spectacular - that is why we watch, isn't it? This is supposed to be like NASCAR, right?!mod 70 was underpowered. if not, it would have easily walked away.
Sort of like the Catri 25?If not for the need to attract spectators with large teams running around, it's possible that the ultimate foiling platform would keep shrinking to the point where the AC could be sailed in 25 footers. We could call it the Little AC..
