A DAY after Singapore sailors Justin Liu and Sherman Cheng won the Australian 420 Nationals title in Adelaide, Koh Seng Leong and Elizabeth Yin have also secured two more victories for the Republic.
The duo won the Australian Laser National Championships Radial Men's and Women's titles respectively.
Koh maintained a strong lead throughout the six-day competition to win by a comfortable margin, 29 points ahead of the runner-up, Malaysian Mohamed Romzi.
This is the two-time Olympian's first win in the Laser Radial division at the Australian Nationals.
In 2003, he narrowly missed gold, finishing second in Adelaide.
In 2002, he finished ninth in Albany.
Three-time world champion Yin finished the regatta as the top female sailor, in ninth place overall. Fellow teammate Victoria Chan clinched a bronze in the women's division.
Colin Cheng, who won an Asian Games gold in the Laser 4.7 class, is now sailing the Laser full rig and completed the regatta in ninth position overall.
Youth Olympic Games sailor Terence Choo finished in third overall in the 45-strong fleet in the Laser 4.7 category.
Said Mark Robinson, Singapore Sailing's head of high performance: "The varied medium to strong wind conditions with significant waves experienced in Adelaide are very similar to those in Shanwei, the venue of the 2010 Asian Games sailing competition.
"This will help our sailors immensely as they prepare for the Games and the upcoming Asian Sailing Championships in March."
