America's Cup 2021: Team NZ prepare to launch second boat to defend 'Auld Mug'

Locked up and going nowhere - behind Team New Zealand's massive viaduct base lies the secret weapon they hope will retain the America's Cup. 

"There's a little bit of apprehension and a few nerves in launching a new boat," says Team NZ skipper Glenn Ashby. 

And there's reason to be, after they've had to watch all three challengers hooning around Auckland’s Waitemata Harbour in their second boats. 

"Launching your final race boat is an extremely exciting period and the amount of work gone in behind the scenes... this boat has really been years in the making,” says Ashby. 

With less than a month to go before the Christmas Regatta, the team have had to dismiss reports they haven't paid the entry fee of $435,000 dollars on time. 

"[The challengers] think they can rattle the cage somehow, particularly rattling up 'Dalts', which is just like a national pastime with other teams," says editor Richard Gladwell. 

Gladwell expects something pretty special, when Team NZ reveal their second boat on Thursday night. 

"I've got a feeling they've put the work into the rig to be honest,” says Gladwell. “That's the biggest area of development."  

So don't expect anything as outrageous as the cyclors Team NZ unveiled in Bermuda or as out there as Ineos Team UK's bow, which has already turned heads.. 

"There will be, I'm sure, some surprises, but everyone will have to wait and see what that is tomorrow," says Ashby. 

While coordinated training between teams is prohibited, there have certainly been moments when the challengers have lined up against each other.  

Team New Zealand are itching to get among them.
