...If foiling was such a magic trick then the last C-class challenge would not have seen the full foiling version being amputated with a grinder.
Moths were VERY limited in the waterline length and maximal attainable power (due to limited width) and there foiling allowed for a significant jump in performance (about 20%)...
Another lesson in the difference in relative performance compared to absolute performance.
Wouter,
The C Class has limited dimensions and limited sail area, while the current AC boats have limited dimensions and
unlimited sail area. This contributes to make extrapolation unreasonable. The moth is indeed a special case, also unreasonable to extrapolate.
I think the 90ft X 90ft platform could benefit from foils that increase stability (Bruce foils), allowing for more sail area - which is unlimited - to be carried in that same platform.
Alinghi ressearched hydrofoil configurations very seriously, including that of my boat, while everyone knows that BMW Oracle already used banana foils. I suggest we wait for a while before discarding foils.
