HONG KONG'S windsurfing queen Lee Lai-shan will be looking to capitalise on home territory to the fullest when she battles it out with her rivals in the Mobil Hong Kong Open Championship starting tomorrow at Kwun Yam Wan, Cheung Chau. Former world champion Lee, affectionately known as San San, is based in Cheung Chau and will be aiming to beat Barcelona Olympics bronze medallist Dorien de Vries of the Netherlands and China's number two Hwang Ying, who are expected to be her closest rivals, over the four days of competition. De Vries beat San San at the Barcelona Olympics two years ago with San San finishing eleventh and the Hong Kong number one female boardsailor will be looking for revenge this time out. San San, currently ranked number one in the world, showed her authority last weekend by winning the final leg of the Mobil Circuit at Stanley. Hwang is not expected to be a pushover and indicated her strong challenge for this title by beating a strong international cast last month in China to win the Xiamen and Chaoyang legs of the Women World Champions' Tournament. Four-time Hong Kong champion Sam Wong Tak-sum, who like San San won a silver medal in the Hiroshima Asian Games, is highly favoured to win the men's title especially after retaining his Mobil Hong Kong circuit title last Sunday. The 28-year-old has moved up the world rankings list and is now sixteenth in the world and he will be hoping to repeat his earlier success in this event when he won the Mobil Open title in 1992. For the first time in the 15-year history of the annual windsurfing spectacular, sailors from Pakistan will be competing. They will be joined by overseas teams from Japan, China, Singapore, Malaysia and Macau. More than 100 local and overseas boardsailors are expected to contest the four-day Open with prizemoney totalling $24,000. Ten races are scheduled for the international classes and a five-race local class competition will be held simultaneously on the final two days of competition. Hong Kong Sports Institute head coach Rene Appel expects conditions to be good for the races. 'It was brilliant today. The wind was about 15 knots which was ideal,' said Appel. 'Dorien [de Vries] excels in stronger winds while San San does well in medium to strong winds. Hwang Ying does better in light conditions. '
