San San hit by double trouble
Lee Lai-shan had a day to forget as her hopes of World Championship glory took a dive in South America.
The Olympic gold medallist made crucial mistakes at Mar del Plata in Argentina and finished a disappointing ninth in races nine and 10.
Now with just two races to go, San San has slipped to second in the standings behind arch-rival Alessandra Sensini, who has a three-point lead.
'The little mistakes and inconsistency of board-speed and board-handling show her lack of time on the water,' San San's coach Rene Appel said.
Explaining where she went wrong in the races, Appel said: 'In race nine, San San started well in five to six knots, and was heading to the right side of the course when Sensini tacked away.
'With a lot of hard work in the very light wind conditions, she managed to finish ninth.' Although she nearly got away with her mistakes in race nine, San San paid for her blunder in the next race, which was won by Italian Sensini.
'Winds were up to 11-12 knots and increasing,' said Appel. 'San San crossed ahead of the whole fleet and tacked on top, but was unable to hold her leading position.
'She rounded the top mark in fifth position, but lost more places when she fell in on the downwinds when her boom end touched the water.' San San's advantage over Sensini has now vanished and she needs a good sail today. 'In tomorrow's two races San San will have to fight for top positions as well as gain four places over Sensini,' Appel added.
