Team New Zealand today revealed what vessels competing in the next regatta will look like.
It's being labelled as a bold new design that could change the future of the America's Cup.
The ac-75 model moves from a catamaran to a monohulls with foils for the first time.
Team New Zealand CEO Grant Dalton said "it's a bold move but you should expect bold moves from an organisation like this."
As defender and challenger of the record, the Team New Zealand and Luna Rossa design teams have spent the past four months looking at a wide range of monohull concepts, moving away from the catamarans that took the kiwis to victory in Bermuda.
"Really it's a lot easier for the world to relate to a monohull," Mr Dalton said.
"Most people sail monohulls and they can understand what we're doing."
The new design has twin-canting retractable foils on either side of the boat. One is in the water to provide stability - the boat can even right itself if it capsizes.
Another feature is its sheer speed. Design boss Dan Bernasconi said though it's early days "we think once the boats are foiling they've got the potential to end up actually faster than the AC catamarans in Bermuda."
Despite the innovations, the new class is being seen as a move back to tradition compared with the rampant use of technology in the last regatta.
The ac75s are challenging and demanding to sail and reward skill.
The boats will see more sailors, but not cyclers - they're gone and grinders are back.
Yachting commentator Peter Lester reckons that this time batteries could power the hydraulics.
"I think you will see some of the designers tap into the motor car technology because of battery use."
Today's design release coincides with a new Government report.
It estimates the America's Cup could give the economy a boost of up to one billion dollars.
It could also create more than 8,000 jobs between 2018 and 2021.
