Great Britain's Star crew secured gold in a wind-effected final day of the French World Cup regatta in Hyeres.
Iain Percy and Andrew Simpson romped to victory by winning the medal race by 1 minute 20 seconds.
"This World Cup event in France has been an interesting week," RYA Olympic manager Stephen Park told Press Association Sport. "It has been particularly windy for a lot of the competition and that has meant it has been challenging for the race teams.
"We only competed in a few Olympic classes, most of them having competed in the Palma World Cup regatta and now being back in Weymouth training specifically for the Olympic Games, but in the Olympic classes we took part in we did well.
"We won the gold medal in the Star class and that sets Iain Percy and Andrew Simpson up well for the World Championships next week."
Alison Young missed out on a podium spot by one point in the Laser Radial event after being involved in an intense tussle with fellow British hopeful Charlotte Dobson in the medal race.
Things were equally frustrating for 49er duo Stevie Morrison and Ben Rhodes, who were denied the chance to improve on their fourth-place standing after racing in their class was called off for the second successive day.
