The racing has been much closer than many recent Americas Cups. There have been plenty of lead changes and some great tacking duels. It must be harder for the defender going into the AC finals going up against a crew that has just tuned up the boat and crew through a regatta with three elimination rounds. The Oracle boat seems to be capable of keeping up with the NZ boat in a drag race but they just can't maintain speed through maneuvers the way the Kiwis can. I'm sure the boat design plays a part in that but I wonder how much of it is crew experience. The on-board video and audio really shows how hard those guys work.
