Home support and light winds - despite a forecast for thunderstorms - helped local sailor Audrey Pei Lin Yong (SIN) on Tuesday at the Singapore 2010 Youth Olympic Games.
Yong came fourth in race one and first in the second race in the girls Techno 293, fighting off strong performances from world champion Naomi Cohen (ISR) and Veronica Fanciulli (ITA) on the first day of the regatta at the National Sailing Centre.
"The winds out there were quite light, quite shifty, but it is home ground advantage so I have been training in this kind of winds for the past two weeks. It's normal," said Yong.
Fellow Singaporean Darren Choy had a slow start to the regatta, finishing 11th and seventh in his two Byte Cll class races, while Just van Aanholt (AHO) had the best day, coming second in the first race and first in his second race.
"I was not expecting it; I would have been happy with a top 10," van Aanholt said.
Constanze Stolz (GER) and Lara Vadlau (AUT) won the girls Byte Cll class races.
In the boys Techno 293, Kieran Martin (GBR) won the opening race and finished second in race two.
Mayan Rafic (ISR) won the second race to go with his top five finish in the regatta opener.
Racing resumes at midday on Tuesday, 18 August.
