Home boats will feature in every rowing World Cup final as Great Britain's rowers continued their successful return to Eton Dorney, ten months on from their triumphs there during the London 2012 Olympics.
Brothers Peter and Richard Chambers, in the new-look lightweight double scull, progressed after taking second place behind Norway in their semi-final, though they admitted it was tough work.
Cross wind conditions meant that lane orders were changed so that the crews with the best preliminary round performance moved from the middle lanes to lanes five and six.
“It was more of a mental challenge than a physical challenge," said Richard Chambers.
“We felt strong but it was more of a battle against the conditions than it was against the rest of the field.
"It was a bit weird because we’ve never trained as a double in these conditions but hopefully, sitting down with the coaches, it will be something we can learn from.
“The change of lanes had a massive influence. I think the FISA [World Rowing Federation] fairness committee got it right. They did the right thing and I respect them for making a bold decision”.
Meanwhile, Vicky Thornley held off British team-mate Melanie Wilson to book her place in the women's single scull final while Olympic bronze medallist Alan Campbell paced his race behind Olympic silver medallist and European Champion Ondrej Synek to advance in the men's single sculls.
