Boat speed in the new boat is expected to be similar to what was achieved in the last America's Cup through increased time foiling and advances in design and engineering.
"This will be a big change, but it is a necessary one if we are to create a sustainable America's Cup for the future," said Sir Ben Ainslie, the skipper and team principal of Ben Ainslie Racing. "These boats will create a significant cost saving whilst still providing a real challenge for sailors and designers alike."
To lock in the cost-saving measures over the long-term several competitors, including Artemis Racing, have committed to using the new smaller class in the next edition of the America's Cup should they prevail in this one.
"These changes may help some current teams be more competitive, but this is clearly also about building the future of the America's Cup," said Iain Percy, the team manager of Artemis Racing.
The rule changes are being drafted and teams will be asked to vote on these changes before the end of March.
