Yngling dropped from 2012 Games

Ayton, Webb and Wilson confirmed GB's Yngling supremacy in China

The Yngling class, in which British sailors have won gold at the last two Olympic, will not be in the 2012 Games.

The International Sailing Federation has instead chosen the Elliott 6m (modified) boat as its women's keelboat match racing vessel for the next Games.

Sarah Ayton, Sarah Webb and Pippa Wilson won Olympic Yngling gold for Great Britain at Qingdao in August.

However, the Elliott 6m also requires a three-woman crew, and Team GB will now begin to assess its programme for 2012.

Royal Yachting Association racing manager and performance director John Derbyshire said: "We will now consider how best to take this forward."

"We look forward to our women adapting to the challenges of match racing in the Elliott 6m."

In a statement the RYA added: "We welcomes the decision to select the equipment as the Elliott 6m at this juncture, to allow nations to begin developing their national programmes, and ISAF World Cup event organisers to establish fleets of supplied equipment.

"The RYA is now calling for prompt clarification from ISAF as to the 2012 Olympic qualification process for the women's keelboat match racing event, so that the sailors and their support teams can begin to put their 2012 campaigns together."

In 2004, Ayton and Webb teamed up with Shirley Robertson to win the Yngling Olympic title in Athens.

The 2012 London Olympic sailing events will take place at Portland and Weymouth.
