Oracle have ramped up their preparations for the America's Cup clash against Team NZ.

Oracle tactician Andrew Campbell says they have identified weaknesses in Team New Zealand that they have vowed to exploit when the battle for the America's Cup gets underway.

Race one of the best-of-13 series is on Saturday (Sunday NZ time) and the defenders have ramped up their preparation this week, making the most of every minute out on the water by integrating new design elements and fine-tuning their work in the pre-start.

Having not taken part in a competitive match since winning the qualifying series two weeks ago, Oracle have also been keeping a close eye on the Kiwis as they rolled past Ben Ainslie Racing and Artemis to earn the right to challenge for the Auld Mug.

MEREDITH ANDREWS/ACEA 2017 Tactician Andrew Campbell says Oracle will bring a 'fast boat out to the race track'.

While Campbell was impressed with the speed of their boat, he questioned some of their tactics at times which the American believes could open the door for them to take the ascendancy.

"They have some serious strengths. They're going really fast," Campbell told the Oracle Team USA website.

"So we're going to have to make sure we're optimised for every condition that we go sailing in, that we get our weather calls and configurations right. We're going to need to be as fast as we can so we can catch them if we get behind.

"But they've also shown that they're vulnerable in certain positions on the race track in terms of their playbook and their communication. We're going to make sure we take advantage of those weaknesses."

Oracle already hold a one-race lead over Team NZ courtesy of the bonus-point they received for winning the qualifiers.

They were two for two against New Zealand during that stage, winning by six seconds and 29 seconds respectively, and Campbell says that gives them a huge advantage.

"To have those guys go into the match one win down already is a big big bonus for us. We worked hard for that point," Campbell says.

"To beat them in both of those races, not only is there a psychological benefit to us, but there is an actual benefit of a win going into the match.

"Time will tell when we get out racing, but for sure, we're going to bring a fast boat out to the race track on Saturday."
