Spithill v Barker - anyone remember San Francisco?
Kia ora, good afternoon and welcome to Newshub's live coverage of the America's Cup World Series on Auckland's Waitematā Harbour and Hauraki Gulf.
Auckland turned a brilliant day for the opening rounds of racing, setting up another mouthwatering schedule for Friday.
Dean Barker's American Magic emerged as the team to beat, after trouncing Team UK and then upsetting America's Cup holders Team NZ in Thursday's finale.
If the previous three races were walkovers, that fourth encounter showed how exciting these AC75 boats can be.
The Kiwis had technical problems at the start and allowed their rivals an early lead, which they exacerbated by falling off their foils midrace.
But on the penultimate leg, the home team engaged the Americans in a tacking duel and actually snatched the lead around the final mark, before another tactical error allowed Barker to sail away downwind.
Meanwhile, Team UK could not finish their second outing of the day - against Luna Rossa - and have since pointed the finger at the Kiwis for not being completely transparent over a malfunctioning foil system.
Predictably, Team NZ boss Grant Dalton has hit back at the accusations and that war of words may spill onto the water today, with the two teams due to face off twice.
Today's race schedule looks like this:
- Race 1 - Luna Rossa v American Magic (15:12)
- Race 2 - Team NZ v Team UK (15:50)
- Race 3 - American Magic v Luna Rossa (16:40)
- Race 4 - Team UK v Team NZ (17:20)
The Luna Rossa-American Magic match-up may give some clues to how good the Italians are, after they seemed to concede victory to Team NZ early in their opening race and then sailed solo through Team UK's mechanical woes.
North north-easterly wind conditions are exactly the opposite to Thursday and racing will take place on the same Course C, between North Head and Bastion Point.
Best vantage points for today's racing will be Maungauika/North Head, Orakei, Bastion Point and Takarunga/Mount Victoria.
Despite their loss, Team NZ remain favourites to take out this week's World Series-Christmas Race, although American Magic has now shortened considerably as second favourites.
TAB: Team NZ $1.40, American Magic $3.50, Luna Rossa $7, Team UK $41
Team NZ scold UK skipper Ainslee for foil system complaint
Team New Zealand have provided a swift and blunt response to Sir Ben Ainslie's gripe about the supplied AC75 foil cant system.
The Team UK skipper suggested his crew's sub-par performance on the opening day of the America's Cup World Series regatta was partly due to the defenders' refusal to be fully transparent about the FCS - a Team NZ-designed component.
But Team NZ have dismissed Ainslie's subtle jab, claiming all challengers have access to the information needed to operate the system at full capacity.
Team NZ say each team are responsible for the installation, maintenance and operating procedures of their own FCS.
"All teams are provided with full operating and maintenance instructions, and programmes to ensure effective and reliable performance," Team NZ say.
"For the past few months, there has been a weekly coordinated call between all teams every Friday - in an open and transparent environment - to discuss the system and address any developments collectively.
"The maintenance and start-up schedule that has been developed is a comprehensive schedule that is shared and in possession of all teams.
"In answer to Team UK’s suggestion that they only received a software update at 12pm yesterday, this is completely incorrect and inaccurate.
"The last software update was delivered to all teams last Friday, following extensive consultation with all teams - not midday yesterday.
"As far as the defender is aware, Team UK’s foil cant system is fully operational."
Team NZ and Team UK will go head-to-head on Friday in two races as part of the America's Cup World Series.
