In the Yngling Medal Race, two-thirds of the gold medal winning team from Great Britain sit on top of the leaderboard. Sarah AYTON and Sarah WEBB won gold four years ago together with Shirley ROBERTSON, but are competing in Qingdao with new a new crew member Pippa WILSON. They hold the overall lead in the Yngling keelboat fleet although the scores are very close with the Dutch team of Mandy MULDER, Annemieke BES and Merel WITTEVEEN just a single point behind. With points doubled for the Medal Race and the third-place Greek boat a long way behind, the boats from Great Britain and the Netherlands will go head to head in a battle for the Olympic gold medal.
In the Finn fleet, Ben AINSLIE (GBR) is going for this third consecutive Olympic gold medal and starts as favourite to defend his Olympic crown, holding the 12-point overall lead ahead the surprise star of the Finn fleet, Zach RAILEY of the USA.
The Danish team of Jonas WARRER and Martin IBSEN leads by 11 points in the 49ers.
The new Olympic Format, the Medal Race, where the fleet is cut down to the leading 10 boats and the points scores are doubled, will be used to decided the winners in the Heavyweight Dinghy - Finn and Women's Keelboat - Yngling events at the Qingdao Olympic Sailing Center on Saturday. The races will be held just in front of the spectator breakwater at the Qingdao Olympic Sailing Center on a short 30-minute course with Jury boats to officiate the action. The competitors carry their overall scores from the Opening Series of races through to the Medal Race and the medals will be decided by combining the Opening Series score with a boat's Medal Race score. The Medal Races for both the Finn and Yngling events will be broadcast live and will be followed straight away by the medal ceremonies, held on a specially constructed platform inside the marina.
