But he admitted he was happy with the position his team were in. He said Oracle were fast running out of time to make any changes to their boat - and any changes they did make would come with trade-offs in other areas.
"The good thing is they're obviously a little bit rattled now and they've got to make some big decisions because they'll probably try to shut down the advantage that we have upwind, but there's obviously other things that go with that."
Spithill has been upfront about his team's position. Oracle could have feigned problems with the boat and limped back to the shed. But they called it for what it was - a strategic play.
The plucky Aussie skipper remains confident, outwardly at least, that his team can get back into the match. They will be back out on the water training on today's rest day trying to iron out some of the kinks in their boat-handling.
"We need some time to really assess our programme and the boat and we need to get it heading in the other direction," he said. "Fortunately we've got the time, and fortunately we've got a lot of races left. We're doing everything we can to win."
