Brazilian Olympic champions Martine Soffiatti Grael and Kahena Kunze overtook the previous leaders on the final day of the 49erFX event to win the gold medal at the Sailing World Cup in Miami.
Yesterday's leaders of the 49erFX, New Zealand's Alexandra Maloney and Molly Meech, needed a top six finish in today's medal race to win gold.
The duo got caught out on the wrong side of a big wind shift, however, and could only finish ninth.
Grael and Kunze, Rio 2016 Olympic champions, finished second to overtake Maloney and Meech in the standings and claim victory.
"For us our goal was to have a clean start because in this light wind it’s very easy to get caught by the boat to leeward and I think we did that successfully," said Grael.
"It was pretty shifty, I was very happy with how the racecourse was set up."
Britain's Charlotte Dobson and Saskia Tidey were fourth in the race to earn the bronze medal.
In the 49er event, pre-race leaders Erik Heil and Thomas Ploessel of Germany finished third to take the gold.
Dylan Fletcher-Scott and Stuart Bithell of Britain won the silver medal, while Šime Fantela and Mihovil Fantela of Croatia took home bronze.
