The commodore of the New York Yacht Club has slammed the idea of a one-off match between Team New Zealand and Ineos Team UK, calling the suggestion a "huge step in the wrong direction".
Rumours have been rife about a Deed of Gift match between the defender and new Challenger of Record, which could take place as early as next year in the Isle of Wight where the Auld Mug was first contested in 1851.
In a statement, Commodore Christopher J Culver said the New York Yacht Club would not support that decision as it excludes other entries.
"The two previous Deed of Gift matches, in 1988 and 2010, were distinct low points in the history of the America's Cup," Culver said.
"Regardless of the conditions, the New York Yacht Club will not support a Deed of Gift match or an America's Cup competition that, due to the schedule and rules for competition, is effectively open to only the defender and Challenger of Record.
