Great Britain have won five gold medals at the opening World Cup event of the season in Munich.
Pete Reed and Andrew Hodge triumphed in the men's pairs while Helen Glover and Heather Stanning took the women's pair.
Tom James returned to help Matthew Langridge, Richard Egington and Alex Gregory clinch victory in the four.
Katherine Grainger and Mel Wilson took the women's double sculls title while Hester Goodsell and Sophie Hosking won the lightweight double sculls.
In total, Britain won 11 medals, though World and Olympic champions Zac Purchase and Mark Hunter failed to medal in the men's lightweight double sculls.
"We've had a really good World Cup," said David Tanner, the team's performance director. "We have seen what we expected here and that is that the standard of the world is coming up again.
"We've got some things to improve but it's been fantastic to have so many great medal performances."
Reed and Hodge were expected to win the men's pair race in the absence of New Zealand's world champions Hamish Bond and Eric Murray, who have won the last dozen races between the crews.
And the British duo delivered, pushing on from the 700m mark to leave Italy and Greece in their wake.
"It's good to win but we would have raced and prepared differently if New Zealand had been here," said Reed after the victory.
Double sculls world champion Grainger was accompanied by Wilson, who was filling in for the injured Anna Watkins and the duo enjoyed the most comfortable victory of the day, leading from the start and beating the United States boat into second.
"It was enjoyable because we felt no pressure," said Grainger.
"But we knew we could be fast. We have simply been working on the important things not the tiny little adjustments you make when you have been together longer."
In the women's pair, Glover and Stanning also lived up to their billing as the top seeds with the New Zealand world champion boat not racing.
The Americans pushed hard in the second half of the race but left their charge too late to trouble the British boat.
Beijing Olympic champion James is back in the men's four boat and they showed a return to form.
The German crew surged into an early lead but the British quartet soon reeled them in and held off a spirited Greek challenge to win.
"We have a new crew with a new dynamic, that is refreshing," said Gregory.
"This race is a great start, but we're certainly not the finished article yet."
In the lightweight women's double sculls Goodsell and Hosking overcame a halfway deficit to pip team-mates Kathryn Twyman and Andrea Dennis to record a one-two finish for Britain.
"We knew our second team was fast, so it is good for them to get silver here," stated Goodsell.
"But in Lucerne we will meet our big opponents. We don't know yet where we are."
A further silver was won in the men's double sculls where Matthew Wells and Marcus Bateman were edged out of gold on the line by Germany.
The lightweight men's four came down to a blanket finish with the British boat finishing third behind Denmark and France and only two-hundredths of a second covering the medallists.
A second bronze followed in the women's quadruple sculls.
The success followed the four medals for the Paralympic-class crews on Saturday.
Paralympic champion Tom Aggar continued his unbeaten run since 2007 by winning the adaptive men's single sculls by a considerable distance.
The Londoner was well clear after 250m and continued to pile on the pressure to win by almost 14 seconds.
There was also a gold and bronze for Britain in the mixed adaptive coxed fours.
The first-string crew, featuring newcomers Pam Relph and cox Lily van den Broeke, won gold despite 2009 world medallist Dave Smith catching a considerable crab with 300m to go.
The team, which also included world and Paralympic medallist Naomi Riches and James Roe, beat Germany with the second GB crew of Kelsie Gibson, Katherine Jones, Luke Almond, Ryan Chamberlain and Rhiannon Jones edging out into third.
There was also bronze in the adaptive mixed double scull for Captain Nick Beighton, a relatively recent recruit to the sport, and Samantha Scowen, who was a world championships finalist in 2009.
