But constantly light winds, fluctuating from 7-11 knots, meant this wasn't a typical day of foil racing, with long periods of displacement racing - both up and downwind.
Co-helmsman on the Italian boat - Francisco Bruni - admits he wouldn't be disappointed if Sunday's two races brought similar conditions.
"In the light wind, definitely our big foils are helping us," says Bruni. "It's a combination of things, probably sails, power in the sails, power in the foils.
"We like the light wind definitely, but today was weird, because it was more gaining in the puffs. You had a difference of 3-4 knots. It was a matter of staying in the pressure."
Luna Rossa dominated winless American Magic in the opening race on Saturday, making the most of the tricky conditions and eventually building on the final leg, recording 40 knots in boat speed.
Conditions were so tricky, Patriot was left out on the course without a puff of wind in sight and eventually was handed a 'did not finish' by race officials.
"It was very challenging," Bruni says. "It was one of those races you can win or lose very easily.
"It was really demanding for the boys."
Unfortunately for the Americans, light winds are forecast for their sole race on Sunday against Luna Rossa.
Under the leadership of America's Cup veterans Terry Hutchinson and former Emirates Team NZ helmsman Dean Barker, the New York entry have had a disastrous start to a regatta they entered as favourites.
Three losses from three leaves the crew desperate for a win or face an uphill battle reach the Prada Cup finals next month.
Hutchinson says the crew are frustrated, especially with two big losses on Saturday, and hope Auckland's breeze will return, so they can show off their boat speed.
"Yesterday was a stable breeze day and we made some tactical mistakes.
"I think we're just looking for the opportunity to have a reasonably open race track and do what we know we can do, which is race well and put the boat in positions to let Patriot do her thing.
"I think we're all a bit angry. We know that's not who we are and I think we're all probably a bit pissed off.
"We want to go out and race consistently, and do things well and be who we are - that [performance] is not us.
"I'm sure if you said to everyone right now that we could go back out and race, we'd go back and race right now."
