The GB Rowing Team men's eight have won the Windermere Cup in Seattle - only the third crew in the history of the event to beat the University of Washington men's crew dubbed "The Huskies".
They came home two seconds ahead to finish in 5:54.0 after a tight race.
Earlier the GB women had raced neck and neck with the University of Washington women's crew before losing out in the final 500m. Washington's winning time was 6:27.9 to GB's 6:31.3.
"They were two close races today and that's what we came here for", said Sir David Tanner, GB Rowing Team Performance Director.
He added: "All credit to the Washington crews they have given us a great early season competition. We've had a very warm welcome here and I'd like to thank Windermere Real Estate whose founder John Jacobi and his family, plus the Seattle Yacht Club, have made it possible for us to be here".
The GB Rowing Team competed today at the event for the first time since a GB women's crew took part back in 1998 and beat Washington.
Crews from the University of Washington have been taking part in a regatta every year since 1970 in Seattle to mark the opening day of boating at the Seattle Yacht Club.
The event was backed and developed originally by Jacobi and has developed into somewhat of a tradition in the Northwest of the USA.
Tens of thousands of "Seattleites" flock to the Montlake Cut each year to witness 800 rowers taking part in races which culminate in the Windermere Cup. This is followed by a parade of boats.
A squad of 22 British rowers flew out six days ago to the USA to take part in two eights that blended youth with experience.
Bob Ernst, Director of Rowing at the University of Washington - whose crews have won both the men's and women's races for the past seven years - said: "I wanted to invite Great Britain here as they 're the best program in the world".
