Bouwmeester makes Olympic history following dinghy gold medal
Bouwmeester has now overtaken Great Britain's Hannah Mills, who won three Olympic medals between 2012 and 2020.
The 36-year-old won silver in this class of sailing in London in 2012, earning her first gold medal in Rio before earning a bronze medal at the Tokyo Games three years ago.
Denmark's Anne-Marie Rindom, who won gold in Tokyo three years ago, settled for silver this time around, with Norway's Line Flem Hoest taking the final podium place.
"It's nice to finally finish it off - it hasn't sunk in yet," Bouwmeester said.
"I have so much respect for Line and Anne-Marie, we push each other all the way."
Australia's reigning Olympic champion Matt Wearn grabbed gold in the men's dinghy, with Pavlos Kontides of Cyrpus picking up his second silver.
Stefano Peschiera ended Peru's 32-year wait for a medal with his bronze medal finish, while Team GB's Michael Beckett ended the final in 10th.
