Welcome to live updates of races 6 and 7 of the 34th America's Cup. The opening race of the day will begin at 8.10am. Emirates Team New Zealand head into the day with a five point lead (4 to -1) and need five more points to claim the Auld Mug. The pressure is on Oracle Team USA to get back into this regatta and they've made a change to attempt that.
"The move was sign-posted yesterday when the five-time Olympic medallist joined the team for their training session, while Kostecki was nowhere to be seen - although as one final insult Ainslie was seen wearing Kostecki's life-vest," Dana Johannsen reports.
"Ainslie has helmed the team's 'B' boat in the lead-up to the regatta, but speculation he would join the crew surfaced earlier in the week after questions were raised over some of the decision-making by Kostecki, the team's tactician," she adds.
"The addition of Ainslie is the only change to the Oracle crew. Team chief executive Russell Coutts warned yesterday it would be a big ask of Ainslie."
America's Cup Events Authority chief executive Stephen Barclay has likened today's races to "moving day" in golf. Team NZ holding a five shot lead as it stands then.
Could reach 20 kts for the second race. Which could favour Team NZ who were fast in strong winds on Wednesday.
That's why Ainslie has won five Olympic medals.
20 minutes away from racing.
Get set for another exiciting day of racing which will thankfully include two races, unless Team NZ use their postponement card!
A few facts about Sir Ben Ainslie:
Won his first Olympic medal (silver) in Atlanta 1996 in the laser class.
After that won four straight gold medals first in the laser then in the finn.
Worked as a tactician for Team NZ in 2005 before changing to helmsman in Team NZ's B boat.

10 minutes to go before race 6 begins. Once again the start will be vital. That is where Oracle have had the edge over Emirates Team NZ in the regatta so far.
Oracle will have port entry for both of today's races, which they carry over from Tuesday.
Just a reminder of the race course: From the start line they head to the first mark which is a short sprint away. Then it's up the first downwind leg, around mark 2 to begin the only downwind leg, mark 3 leads them to the final downwind leg before they round round 4 for a short sprint to the finish line.
What I meant was if New Zealand win the start then it seems the race is over from there. If Oracle win the start then we have a race at least.
There's no way Coutts will race in this regatta.
