What a morning's racing to kick off the 2017 America's Cup.

There was plenty of passing and close races, some umpire calls and drama with Team BAR Team colliding with Softbank Japan.

Emirates Team New Zealand demolished the French in their first race but lost by six seconds to arch-rivals Oracle in their second, conceding a big lead in doing so.

Ben Ainslie Racing (GBR) became the first victims of the America's Cup demolition derby, suffering significant damage during their race against Japan off Bermuda this morning.

If they can't quickly repair their boat overnight, Team New Zealand may get a free pass for the scheduled meeting tomorrow.

As BAR and Japan jockeyed for position before the start of the final race on day one of the qualifying series, Japan skipper Dean Barker aggressively challenged his rival for inside running and counterpart Sir Ben Ainslie did not react quickly enough.

The boats made heavy contact, with BAR incurring a split to its hull. The British were penalised, but continued around the course, eventually losing by 48 seconds.

They face a huge job fixing that damage for their next race - they have Oracle Team USA in tomorrow's third race, followed by Emirates Team New Zealand later in the day.

Rookie helmsman Peter Burling had Team New Zealand on the board early in the America's Cup qualifier series, romping home over Team France in their first race off Bermuda this morning.

At 26, Olympic 49er champion Burling is the youngest ever America's Cup helmsman, but gave wily French counterpart Franck Cammas a sailing lesson, controlling the start and rocketing away to lead by one minute 13 seconds by the third mark.

By contrast to their opponents, Emirates Team New Zealand sailed a smooth race, staying on their foils through most of their journey to eventually prevail by two minutes 33 seconds. The Kiwis had crossed the finish line before France had rounded the final mark.

But Team NZ conceded bragging rights against America's Cup rivals Oracle Team USA in their second hit-out, dropping their first head-to-head meeting with the holders.

After their disastrous capitulation in the cup regatta in San Francisco four years ago, the Kiwis would have been intent on gaining an upper hand early.

Emirates Team NZ made a key change to their crew for their second race of the day, bringing Olympic cyclist Simon van Velthooven on board for former rower Joe Sullivan to add grunt to cycle-grinding station.

Oracle skipper Jimmy Spithill held the slight early advantage, establishing a five-second advantage at the second mark.

As both teams jockeyed for position down the third leg, TNZ tacked the better and moved past their archrivals to build a 20-second buffer by the next mark.

But down the fifth leg, the Americans came back strongly and almost drew contact with the NZ boat, as they rounded the fifth mark. That proved the crucial moment, with Oracle easing away for a six-second win.
