London 2012 chairman Lord Coe says the pressure on the Great Britain sailing team to win medals is justified because they will have home advantage.
The GB sailors, who train at the Olympic venue in Weymouth, topped the medal table at Beijing in 2008.
Coe told BBC Radio Solent: "I don't think the expectation is unjustifiable. They know these waters very well, so clearly there is home advantage.
"Every Olympic team I've gone away with has had a successful sailing team."
Coe was speaking at the Sail for Gold regatta at Weymouth Bay and Portland Harbour, the last event before Olympic qualification begins on 31 July.
"I tend to think everything that happens here is a really good example of Olympic testing," he said.
"Having three times the number of boats and people here is a really great example of how you can learn every day.
"This event is three times bigger than the Games, so there is some confidence expressed by the volunteers that if they can deal with this, they can certainly deal with the Games."
