Great Britain's Giles Scott sent out a message to the Olympic selectors on Saturday by seeing off Ben Ainslie and securing victory at the Skandia Sail for Gold Regatta.
Three-time gold medallist Ainslie was chosen to represent Team GB at a fifth successive Games this summer in spite of tough competition from former world and European champion Scott.
However, the 24-year-old proved he is one of the best in the Finn fleet by sailing an impeccable week in Weymouth, winning six races - including Saturday's medal race - to secure gold.
"I feel good, I feel pretty happy with my performance," Scott said. "I can't really complain.
"I put in first and seconds and you can't really ask much more than that.
"Being able to end it by winning the medal race is pretty good as well.
"I wasn't really trying to prove anything with that. It is just quite nice to win races."
Ainslie, by comparison, endured a difficult regatta on the Olympic waters yet still left with a silver medal.
The 35-year-old struggled with a virus at the start of the event, but recovered to take the fight down to the medal race, although he capsized and could only managed a 10th place finish.
"Sometimes these things happen," Ainslie said. "Thankfully it wasn't the Olympic Games.
"I made a mistake, we're all human. It wasn't my best race but Giles sailed fantastically.
"He had a great series and I am really pleased for him to go and show how good he is."
Scott's gold medal was Skandia Team GBR's second of the day, following team-mate Alison Young's surprise victory in the Laser Radial event.
The 25-year-old was a late pick for Team GB's sailing squad but proved her worth in Weymouth this week.
"It is pretty cool to win," Young said. "It was a good medal race out there and I am pretty happy to come away with the win.
"It is a good confidence boost going forward to the Games and I will be looking to build on a few things between now and then.
"There is a few little things we can tweak and work on. We'll have a look back at this regatta and see what we can move forward with."
Young finished the medal race behind Ireland's Annalise Murphy, whose victory on Saturday saw her secure the bronze medal.
The Irish team also had a gold to celebrate on the south coast as Peter O'Leary and David Burrows won the Star event ahead of Brazil's Robert Scheidt and Bruno Prada.
British pair Iain Percy and Andrew Simpson slipped to third in the standings as a result, before Nick Dempsey took bronze in the men's RS:X event.
Earlier in the day, Luke Patience and Stuart Bithell won silver in the men's 470 class, while reigning world champions Hannah Mills and Saskia Clark took home bronze in the women's event.
Dylan Fletcher and Alain Sign finished third in the 49er class, pushing British rivals and Olympic qualifiers Stevie Morrison and Ben Rhodes into fourth spot.
Paul Goodison also just missed out on a podium spot with a fourth-place finish in the Laser, while Bryony Shaw finished eighth in the women's RS:X and British trio Lucy Macgregor, Kate Macgregor and Annie Lush finished fifth in the match racing event.
