It wasn't just the win that gave Spithill cause for confidence. After a couple of subtle modifications to the boat during Saturday's lay day, USA-17 looked to be quicker upwind yesterday, and their crew-work was much sharper.
"This is a key moment for us in the regatta, we clearly made a big step in the boat's performance, the crew are sailing better, we didn't get off the line well and it didn't faze the guys one bit," said Spithill.
"We've been saying in-house that we don't care what the scoreline is, we can still win races, and we're going to fight the whole way to the end."
While it was the first time in the regatta Team NZ returned to the sheds after a day of racing without at least one point in the bag, the Kiwi crew appeared remarkably relaxed about yesterday's passage of events.
Davies said the way his team responded after their setback in the opening race of the day meant they would head into today's two races with a lot of confidence.
Team NZ could have opted to play their postponement card and headed back into the shore to regroup, but they shrugged off the incident and got straight back into it for race two. The Kiwi crew were looking in pretty good shape, too, before high winds forced the termination of the race. Dean Barker won the start after fiercely protecting the leeward end of the line, and they didn't hold back down the first run, hitting speeds of more than 47 knots to lead by seven seconds at the bottom mark.
They were looking comfortable on the upwind leg as well before the race committee pulled the plug because the winds exceeded the prescribed 22.6-knot limit.
"We need to think of the whole day's racing in context - we took a lot out of the day," said Davies. "That second race we felt we had our wheels back upwind and we had a pretty healthy lead when the race got terminated."
Team NZ need three more wins to take the America's Cup. Oracle have now wiped their two-point penalty and any further wins for the defenders will be scored.
