The Olympic sailing great hopes the momentum has swung in the Brits' favour, after pegging Luna Rossa Prada Pirelli back to 5-1 in the first-to-seven series.
Trailing 5-0 into race six, Team UK produced their best performance of the challengers final, leading from start to finish in a complete turnaround from earlier in the day.
The Italians blitzed Sir Ben and crew in the opening race on Saturday, moving within two race wins of a spot in the America's Cup against Emirates Team New Zealand.
But the Team UK skipper is a fighter and some smart sailing in the pre-start gave Brittannia a slight edge on the first leg, which they turned into a 14-second race win.
Sir Ben hopes this is the start of another classic America's Cup comeback story.
"We are off the mark and that gives us a bit of momentum, and as we know, momentum in sport can be everything. We had one good race and one not so good.
"That breeze coming in the second race - we felt that we were okay in those conditions and we kind of hung in there to win
"Credit to Luna Rossa - they sailed away with the first race and kept the pressure on us throughout the second.
"We will keep fighting all the way here and I am really proud of how the guys dug in in the second race."
But Team UK will pray for heavy winds on Sunday or risk going home early.
In any conditions under 13 knots of wind, Sir Ben admits the Italians have a superior boat and with 12 knots forecast for Sunday's two races, the outlook is bleak.
"We will keep tweaking the boat to make it faster in lighter airs - that's where they are strong," he says. "We have to get the best out of the boat - make some tweaks and get faster.
"We have made some improvements, but clearly not enough.
"Tomorrow's [Sunday] forecast looks quite light, so we will see what happens. We would like a bit more breeze, but we will have to take whatever comes."
Rival Jimmy Spithill remains optimistic about his team's outlook, regardless of the wind strength.
"Our boat is great. I'm really happy with the boat in all conditions quite frankly.
"I think we are a little smoother in manoeuvring, but we still have a lot to work on."
