Info is now coming out about what changes were made to the Oracle boat, to get it to foil upwind, and pass the KIWI's on just about every leg 3, if they were behind, after their lay day.
If you recall, they were getting crushed going upwind early on, allowing the KIWI's to get up 8-1, but all of a sudden, the Oracle boat got faster upwind. Today I'm reading reports that Oracle had some help from Boeing, and installed a Stability Augmentation System, to help trim their daggerboard/foils, to get it to foil smoothly, while going upwind. The KIWI's did protest the system early on, but it was allowed.

Oh, and Jimmy Spitthill is an Aussie, not a Kiwi, so our Aussie is faster than their Kiwi! Too bad they did away with the Nationality Rule.
