Yesterday he spoke glowingly of his crew - in particular his afterguard of British Olympic hero Ben Ainslie and Australian hot-shot Tom Slingsby. The Oracle skipper believes the brains trust on board the boat gives his team a huge advantage over Team NZ, who only have tactician Ray Davies calling tactics.
"The one key difference I see in our afterguard is we have Ben and Tom on the back - two of the world's best sailors that can bounce ideas off one another," said Spithill.
"There's a lot of load there, the helmsman and the wing trimmer are so involved in boat speed, they can't get involved in tactics like they could in the AC45s ..."
Davies later dismissed Spithill's talk as just that - talk.
"That's the way they play the game. Jimmy particularly likes to talk things up and that's how he motivates himself. But that gives us motivation too."
But there is no doubt the energy and positivity is much higher in the Oracle camp. Chief executive Russell Coutts is happily chatting away to US media again and after a week and a half, Larry Ellison's super yacht Musashi has suddenly reappeared back at the America's Cup Park.
