Lee Lai-shan got her gold medal wind-surfing campaign at the 13th Asian Games off to a sound start by finishing on top of the standings at the end of day one.
San San was holding a narrow lead over China's Huang Ying as the first day of sailing ended on a highly favourable note for Hong Kong, who have a number of athletes in medal contention.
San San began slowly, being edged by her Chinese rival into second place in the first of the two races yesterday in Pattaya. But the gold medal favourite came back strongly in the afternoon's second race, winning it to slip into the lead when Huang managed only a third-place finish.
While all eyes are on San San, the rest of the large yachting squad also made encouraging starts.
San San's fiance Sam Wong Tak-sum finished second overall in his event to nurture hopes of a repeat performance to that of the last Asian Games in Hiroshima.
Four years ago, Hong Kong's yachting squad won two silvers and a bronze. San San and Wong took the silver medals.
Wong was trailing South Korean leader Ok Duck-il in the men's light race board event. Wong managed a first and a fourth-place finish in his two races.
