Ireland's Annalise Murphy got her tilt at Laser Radial gold off to a promising start on the first day of sailing at Rio 2016.
Monday brought the opening of the Olympic regatta on the waters of Rio, and the 26-year-old began well in Brazil.
Recovering from a bumpy start, Murphy cruised to victory on the Escola Naval course - 21 seconds ahead of Belgium's Evi van Acker in second.
The next race did not go quite as well as she came home 14th, but ending the first day fourth overall was a decent return.
"It was fun," Murphy said. "It was really tricky. It's really up and down, pressure differences across the course and a strong tide playing a big part in it.
"I had two bad starts so I had to fight back from there, but I am happy enough with today.
"I am going to be looking at the mistakes I made - I didn't sail perfectly at all. I can definitely improve things.
"I am just going to look at that and forget about today because every day here with the different race courses will be completely different.
"You can't look at one day and think it'll be the same the next day because it's not."
Carlow's Finn Lynch is 21st in the Laser fleet after the first two races of his Olympic career, finishing 14th and 28th.
