Great Britain's John Gimson and Anna Burnet have won gold at the Nacra 17 Class World Championships in Geelong, Australia.
Compatriots Charlotte Dobson and Saskia Tidey later secured silver in the 49erFX class.
In the final race, where points count double, Gimson and Burnet successfully overcame a 16-point deficit to pass leaders Nathan and Haylee Outteridge of Australia.
"I'm a bit speechless," Gimson said.
"We had to go out and win the final race to give ourselves a chance and in the end all the cards just fell into place for us."
Australia's Jason Waterhouse and Lisa Darmanin took Nacra 17 bronze.
Last month, Gimson, 36, and Burnet, 27, secured a place in the Great Britain sailing team for Tokyo 2020, after being selected ahead of Ben Saxton and Nikki Boniface.
Dobson and Tidey had been in contention for the gold medal but capsized in the final race and lost out to Spain's Tamara Echegoyen and Paula Barcelo.
Dylan Fletcher and Stu Bithell, bronze medallists in 2019, finished their regatta in eighth place after coming home in third in the final medal race.
Meanwhile, Elliot Hanson finished fifth in the Laser World Championships in Melbourne after dropping one place in their final race.
