Oracle Team USA stamped their authority at the Louis Vuitton America’s Cup World Series in Gothenburg today.

The defender won both races on opening day to close the gap on overall points leaders Land Rover BAR.

Oracle Team USA led every leg in both races to underline their dominance and emphatically claim bragging rights back at the race village.

“The guys on board the boat did an awesome job today,” Jimmy Spithill, the Oracle skipper, said.

“Tom [tactician Tom Slingsby] sailed really well tactically in the first race and really made some key calls under pressure.

“Second race was very encouraging because that’s the best we’ve sailed as a team. We were fast, we had great manoeuvres and Tom was just tactically really at another level.”

Oracle moved up from third to second in the overall points standings.

Ben Ainslie, the Land Rover BAR skipper, was satisfied with two second place finishes.

“It was a good day for us,” Ainslie, a two-times King Edward VII Gold Cup winner, said. “We are happy with two second places.

“It was a tough old day out on the course and Jimmy and the guys at Oracle sailed really well and got themselves out ahead. But we battled through and got two good second places and I was really pleased with how we sailed.”

A pair of thirds had Emirates Team New Zealand slip from second to third in the overall points standings.

“Today was a fun day and the racing we had here was probably some of the closest we’ve had in quite awhile,” Glenn Ashby, the team New Zealand skipper, said. “The guys done a great job getting the boat around the track.

“We haven’t had a huge amount of training time between the two events, so to come here to Gothenburg and be able to mix it up with the big boys that have been putting a lot of time and effort in is really nice.”

Artemis Racing, the home team, found the going tough and had to settle for a fourth and sixth.

“Obviously we didn’t have a good day on the results card and we had some damage between the two races,” Nathan Outteridge, the Artemis helmsman, said. “But we were really happy with how we were starting.

“Starting in race one was good and starting race two was actually even better. But unfortunately with a damaged foil we didn’t have any boat speed.”

Groupama Team France posted a fifth and sixth and Softbank Team Japan a fourth and fifth.

Racing continues tomorrow with points doubled.
