Grace Clough, Dan Brown, Pamela Relph, James Fox and cox Oliver James knocked the socks off their own world's best time to win gold at the world cup in Varese today.
The World Champion GB para-rowing mixed coxed four got a flying start and were ahead after just a few strokes. By 300m gone they were a length ahead with Italy in second.
From that moment on, they turned on the power and the pace to win in a stunning 3:13.76 - lowering the world best time that they set in Thursday's heats of 3:15.47.
"We knew we were on for a good time as we've had a good training camp and a great block of training. We wanted to challenge ourselves here in the heat and with conditions the way they were today we knew it was on to break it again today", said Relph.
"I've started my birthday celebrations a day early", said Clough. "This time last year I was so new to racing at this level and I didn't know what was happening. Today I've been able to enjoy it too".
"At 500m we were on record pace, at 750m we were behind. It was great commitment from the guys. That was a much more aggressive row", added cox Oliver James.
Dan Brown said the win and the time augured well for the World Championships: "That felt really great now we will go and get ready for Aiguebelette [venue of the 2015 Worlds] and try and make the boat go even quicker".
Earlier, in the arms-shoulders-only single scull Tom Aggar was drawn between two of his biggest rivals in today's final - Erik Horrie of Australia, the popular World Champion, and Alexey Chuvashev of Russia with whom he has traded verdicts in big events over the past few years.
Chuvashev blasted out of the start and took an early lead with Aggar and Horrie closely chasing before the Brazilian Rene Periera challenged briefly.
At the halfway mark Horrie, as expected moved into a good lead, with Chuvashev in second and Aggar two-thirds of a length behind the Russian. Aggar, World silver medallist in 2014, strived to close the gap and had the overlap with 100m to go.
As the line loomed Aggar was getting closer but did not have quite enough.. Gold to Horrie and silver to Chuvashev by just under two seconds from Aggar in bronze.
"I've got a little bit mixed feelings as I would have liked to have come ahead of the Russian after the results last year", said Aggar. "Today wasn't quite there but I'm now in a reasonable position going towards the World Championships".
Equipment failure delayed the start of the equivalent women's final featuring Rachel Morris for GB who is returning after shoulder surgery. From the outset it was clear that Moran Samuel of Israel and Birgit Skarstein of Norway would battle for the gold - a contest won ultimately by Samuel.
Behind them Morris and Claudia Santos of Brazil tested each other for the bronze with the Brazilian taking the honours.
"That's two really good medals and a fourth place for our para-rowers today and hats off to the four for lowering the World's Best Time twice in Varese", said Sir David Tanner, GB Rowing Team Performance Director.
"This is a strong marker on our mission to qualify our para-boats for the Games later this summer with the new TA double still to come into the GB mix", he added.
The GB para-rowers will next compete internationally at the World Championships in early September in France - an event which doubles as the Paralympic Games qualifying regatta.
