Though I applauded Oracle's decision to go with the catamaran (one can see here, my previous posts about the America's Cup), I now think the AC72 is too big, too powerful, too fast, too scary, and too expensive.
It seems the AC72 in the America's Cup may be in a Catch 22. On one hand, if the boats and crews can handle the conditions, we may have what I call the "human flying squirrel" phenomena; we'll watch the videos once or twice, say "Those guys are crazy" and move on. On the other hand, given the small field competing, if we have two catastrophic failures we may not have enough catamarans left to race the cup. (I also think the race track is much too small for the speeds of these beasts.)
But as I said, with the America's Cup my opinion is usually wrong. I hope it is. I would like to see some great racing in very unique racing machines.
A very good video of Team Oracle; interviews, AC72's in action (and in pieces) :
