The New Zealand SailGP team have finished second at the latest event in Los Angeles after one turn cost them the title.
Facing Canada and Australia in the final, Black Foils skipper Peter Burling made a perfect start as he had done throughout the regatta.

He won the inside line to the first mark one, leaving NorthStar Canada trailing in its wake and Australia skippered by Tom Slingsby out of the reckoning.
However, a vital moment unfolded at the second mark, when leaders New Zealand and NorthStar Canada split the course.
As the Canadians executed silky smooth boat handling, Burling and his team struggled to replicate clean manoeuvres and fell off the foils on the third leg of the shortened six leg final.
The Canadians moved into first with unforced errors from the New Zealand and Australian teams handing them a dominant lead.
"It was great to lead at mark one, but then I felt like we made a few incorrect decisions out on the race track. There's a few things I look back on and kick myself on technically...real shame to let someone pass in a final when you are leading on mark one - you should win those ones," said Burling.
Despite the light wind conditions meaning a reduced four member crew configuration, the Canadians racked up the highest fly time of the day in the final - 99 percent, as well as the highest average speed of the day - 51.07km/h.
It's the first event win the NorthStar Canada has picked up since Christchurch two years ago.
New Zealand's second place finish sees a shift to third on the table at 29 points, with Great Britain leading with 34 and Australia second at 32.
The next event is in San Francisco next week.
