America’s Cup chief executive officer Sir Russell Coutts expects racing in Bermuda to be even better than in San Francisco four years ago.

Coutts was interacting with fans on Twitter yesterday morning and said that Swedish challenger Artemis Racing had been “dominant” on the Great Sound, while outling some of the changes that he hopes will come about for the America’s Cup after Bermuda.

Responding to a fan who asked whether America’s Cup 35 would be “even better” than AC34 in San Francisco, Coutts tweeted: “Final match in SF was brilliant. Now, nearly all the teams are competitive, so race [should] be closer and more competitive overall.”

And while praising Artemis’s strong showing on the Great Sound, Coutts intimated that does not mean that their dominance will continue when the real racing starts.

“Artemis Racing has been dominant in high winds,” Coutts tweeted. “Still need to see light wind performance from all teams. Variable wind is a feature of BDA.”

Coutts also was confident that racing would not need to pushed back into July because of the weather.

“If delays happen, regatta director Iain Murray will need to schedule more races during each day,” Coutts said. “The races are 22 minutes so we should be able to make up time. So we should be OK.”

When another fan asked Coutts “if you could create one boat design related rule, effective immediately, what would it be?”, he responded: “Next version of ACC should have gennakers for very light winds — for both upwind and downwind. And a smaller wing for stronger winds.”

Coutts was not convinced that the challengers would “band together” against defender Oracle Team USA.

“No doubt they’ll be more worried about beating each other at this point,” he tweeted. “There’s not much time to co-operate after teams have been eliminated.”

He is also not expecting a repeat of the thrilling comeback in 2013, when Oracle overturned an 8-1 deficit to Emirates Team New Zealand to win 9-8.

“That was an amazing comeback,” Kiwi Coutts tweeted. “Hard to imagine we will see that again in our lifetimes.”
