In the girl's fleet Siripon added another two wins in races 9 and 10 to compliment the two first on the previous day of racing. She excelled in the lighter winds that predominated in the second half of the regatta. Lin Hai Xia (CHN) and Man Ka Kei (HKG) held on to take second and third overall - with other members of the China team close behind.
The top two nations in both the boys and girls fleets qualified to compete in the first Youth Olympic Games that will take place this summer in Singapore:
In the Boy's fleet Hong Kong and China took the two places, whilst in the Girl's they went to Thailand and China.
At the Techno 293 Oceania Championships in Adelaide, Australia, the Oceania Qualification Event, the sweltering 40 degree heat brought the regatta to an early finish with no racing on the final day.
With just one YOG place up for grabs from this championship, Australia qualify for Singapore in both the Boys and Girls windsurfing events.
The next qualification event for the windsurfers is the Techno 293 South American Championship taking place in Sao Paulo, Brazil.
