Hong Kong's Lee Lai-shan moved into a challenging position for a top-three finish at the World Championships in Haifa, Israel, following creditable results on the third day of racing. Lee, the 1993 world champion, finished third and fifth in her two races and has jumped three places to fifth overall at the halfway mark of the 12-race programme. Defending champion Maud Herbert of France has virtually wrapped up her third straight world crown after winning four of the six races held and finishing second in the other two. Lee, however, still stands a chance of winning the runner-up prize being on 29 penalty points while second-placed Barbara Kendall, the Barcelona Olympic gold medallist from New Zealand, is on 21 points. American Jayne Fenner is now in third position with 25 points and fourth is Dutch sailor Dorien de Vries on 28. 'It would now be very difficult for anybody to catch Maud Herbert because the weather forecast for the next few days is for stronger winds and rain, conditions which suit her,' said Hong Kong coach Rene Appel. 'It was unfortunate San San missed the start in two of the races but she has been improving with every day and we're very hopeful she can finish in the top three by the end of the week.' Hong Kong champion Sam Wong Tak-sum moved up three places to 41st position in the men's division after placing 43rd and 35th in the first two races of the finals. Wong, the only Asian sailor to qualify for the 60-strong men's finals after finishing 44th in the five-race qualifiers, is now aiming for a top-30 finish.
