What's the thinking behind the Italian wing shape? Shown in the diagram on the above link

I understand the initial two boats (trainers) will get simple, AC45-style wings. The third boat will add lead element plain flap ... beyond that, they aren't saying.

There seems to be quite a bit of money behind this program. 4 boats between now and the I4C in 2013, plus a pretty big team by the looks of it.

Could it be to get more of their sail area higher up for better wind?

If you look at the diagram, you'll notice that the previous C-class designs appear to have a 2-3 panel type wing shape, although Canaan is much closer to elliptical than the others. The idea presented by challenge italia looks pretty darn close to full elliptical (i.e, most efficient planform), with some exceptions. There is still more area at the bottom than the top compared to an ideal planform shape, but that is needed to keep the righting moment low. Of course, this is all much speculation, the ideal planform shape aerodynamically can be achieved using proper twist (essentially flap settings on a C) and airfoil selection in conjunction with a multi-panel wing shape. The Italian entry looks to be more difficult to construct than the others but they look to have a comparatively unlimited budget so...

Interesting read, contradicts basic theories and goes straight to the hardcore stuff. Will be fun to see what the next generation of C-Class and AC72 wings looks like!

It was a great read. I had run in to it before. I am anticipating the 2013 I4C more then I am the 2013 AC even though those will be 72' beasts. You will also have more competitors at the I4c then the AC.
