Both boats were made primarily with NZ sailing technology, about the only part made outside NZ was the hulls which had to be from the country of origin (but it was a kiwi design ) WingSails, sails, foils etc etc, all from NZ.
But Larry Ellison owned Core Composites, the NZ based company that built most of the boats. So the technology breakthrough that got Oracle some speed was not available to ETNZ
That being said, remember there were a couple of Aussies in the ETNZ team, it wasn't an exclusive group. And there had to be input from other countries as well. Big kudos to Luna Rossa who stayed on to help ETNZ tune up before the real thing, they could have sulked and walked.
Ok, so we didn't win it this time but we're still the only country that has ever won it and defended it successfully in past events.
We'll be back, it's only a piece of metal after all and all NZ is applauding the ETNZ team for the heroic efforts and the incredible racing and spirit they did it in.
Remember, we came second, the rest of the world didn't even get close ....
