Britain's next America's Cup syndicate Team Origin will sail under the flag of the Royal Thames Yacht Club.
Alinghi beat Team New Zealand to win the America's Cup in 2003
Under America's Cup rules, each entry must be backed by a club.
And with the choice of club in place, Team Origin could be chosen as the next challenger of record - the team that helps the defender stage the Cup.
Team Origin, headed by Sir Keith Mills, will take part in the next two Cups. The Royal Thames was founded in 1775 and is Britain's oldest yacht club.
"We aim to support Team Origin's vision and values," said John Stork, vice-commodore of the Royal Thames Yacht Club.
"In particular helping to encourage participation in our sport by building awareness and excitement across Britain about the ambitions of the team and why winning the America's Cup is such an important and worthwhile goal for the whole country."
Britain has never won the America's Cup since its inception off the Isle of Wight in 1851, and last competed in the event in 2002 before losing in the quarter-finals in Auckland.
The GBR Challenge syndicate subsequently folded, leaving Britain with no entry for this year's event in Spain, hosted by defending Swiss champions Alinghi.
