Expected to be able to reach incredible speeds, the 2021 event could be the most exciting from a spectator's view point yet.
Executive director and skipper for New York Yacht Club's American Magic challenge Terry Hutchinson was a tactician with ETNZ in the 2007 America's Cup, and told AmericasCup.com, for him, it was good to be getting back to familiar waters.
"I look forward to being out in the Hauraki Gulf, or between North Head and Takapuna. We know the area, we know the race course, and I'm looking forward to a successful regatta becuase in the end that's what we're going for."
While having the choice of venue to host the regatta might be an advantage, ETNZ electing to hold it in Auckland might not give them the usual home field advantage.
Members from all three of the confirmed challengers have spent plenty of time on Auckland waters and are familiar with how to handle to conditions.
INEOS Team UK skipper Ben Ainslie knows Auckland well, and told AmericasCup.com he was prepared for the challenges of what can be a difficult area to sail.
"The conditions are very changeable, there's quite a lot of tide, and the best part about it is Aucklanders love sailing - it's called the City of Sails, so the America's Cup I think will be a big success."
