Sir Ben Ainslie said his Land Rover BAR team had sent out a "strong message" after clinching the America's Cup World Series in Japan this weekend.
Land Rover BAR sealed the overall ACWS title with a race to spare in the final event in Fukuoka on Sunday, with Ainslie's team also winning the Japanese regatta after edging out Artemis Racing on a tie-break after both teams finished on 75 points.
The ACWS success gives Land Rover BAR two potentially crucial bonus points to take into next summer's America's Cup qualifiers in Bermuda.
Ainslie said following his team's success on Sunday: "It was an amazing day for the team because our core goal was to win the overall series, that is what we came here to do.
"To achieve that and come out on top in the final event, to get four regatta wins in the overall series, that is a huge achievement from a completely new team.
Ainslie, the most successful sailor in Olympic history, is attempting to end Britain's long wait to bring the America's Cup back to the UK, where the oldest trophy in international sport was first contested in 1851.
Sir Ben's wife Georgie tweeted a congratulatory video from the couple's daughter Bellatrix:
