Even knowing it's a fake, there's a lot of things on that concept drawing that just don't add up for me. The biggest is that the sprit and associated dolphin striker are way too low to the water, even if it is a planing design.

I for one am hoping that the AC Cat scenario comes to fruition, and that it generates some excitement. If for no other reason than to add a bit of irony to the whole Olympics thingy...
