Annalise Murphy has moved into second place after five races in the Laser Radial class at the World Sailing Championships in Perth, sealing qualification for the 2012 Olympic Games.
With 18 knots of wind and choppy conditions to contend with, Murphy finished second, first and fourth in today’s three races. With five races completed, the Dubliner can discard her worst result - a 30th place finish in the first race of the series.
Combined with her victory in the second race of the series, today's results mean Murphy is just two points behind leader Evi Van Acker of Belgium.
The Rathfarnham 21-year-old, who sails out of the National Yacht Club in Dun Laoghaire, will take part in five more races before the top 10 go through to the medal race on Sunday.
The 102 boat fleet now splits 50% into Gold and Silver fleets. The split means it is now impossible for Murphy to fall outside the top 29 nations thus securing Ireland's place on the start line in London.
In other classes, Ger Owens and Scott Flanigan are lying in 31st position in a fleet of 80 in the 470 class. In the Finn class, Ross Hamilton is in 63rd position.
Irish sailors in the other three classes do not start racing until 11/12 December. They are currently undergoing pre-race preparation including measurement.
