Sailing: Australian skipper Tom Slingsby hits out New Zealand's SailGP practice on eve of inaugural leg

The inaugural SailGP New Zealand is less than 24 hours away, and the Australians are already complaining.

Australian skipper Tom Slingsby isn't happy the New Zealanders were allowed to get on the water on Thursday, and has called the decision to cancel today's practice 'overkill'.

Forecast high winds leading to the cancellation of Friday's practice, a decision American driver Jimmy Spithill agrees with.

"You don't want to blow the weekend by making the mistake today," he said. 

But Slingsby believes organisers are playing it too safe, after destructive winds swept through the last event in Sydney, leaving no spare boats and a lack of spare parts.

"It might be overkill," he said. "It sucks for us.

"We want to get out there and train in a venue we've never sailed before."

Adding to their frustration, New Zealand were given an exemption to practice on Thursday.

"We probably got about 15 minutes of sailing out there, just to load everything up," said NZ driver Peter Burling.

That has their rivals feeling like they're at a disadvantage, before racing has even begun.

"I sort of felt that it wasn't really fair to the other teams," Slingsby said.

"Without a doubt getting on the water yesterday has proved, given the weather, an advantage, yeah?" added Spithill.

With just two events before the top three finals in San Francisco, teams are in a race to book their spot.

"We'd love to do it here in New Zealand," said Slingsby. "Obviously it wouldn't be a popular result with the locals."

And he's not alone there either.

"A guy came up to me on the street the other day and said oh you're basically the red headed step child of New Zealand," joked Spithill. "I took it as a compliment obviously."

The Kiwi-Aussie rivalry is well and truly alive at the inaugural SailGP New Zealand.
