A sailing academy where part of the 2012 Olympics is being held is to get a multi-million pound upgrade.
"Several million pounds" will be spent on the upgrade
Changes to the Weymouth and Portland National Sailing Academy will turn it from a "top class setting into a world class training and competition venue".
Olympic chief Lord Coe said the revamp would create a "stunning amphitheatre" for athletes and spectators in 2012.
The purpose-built venue will host Olympic events as well as providing accommodation for the competitors.
The academy, already rated as one of the best small-boat sailing locations in Europe, is to get a longer dual-aspect slipway and more race-boat parking, lifting and mooring facilities.
The Olympic Delivery Authority (ODA) said the upgrade would run into "several million pounds".
Planning applications are to be submitted by Spring 2007 with test events set for 2010.
Lord Coe, London's Olympic organising committee chairman, said: "The design enhancements, along with the proposed course layout and consistent wind conditions set in the Bay of Weymouth, will create a stunning amphitheatre for Olympic and Paralympic sailing teams and spectators in 2012."
Bill Ludlow, chairman of the Sailing Academy, said: "In addition to meeting the needs of the Games these works will help us in our work to enable more people to learn and participate in the sport.
"They will be a permanent legacy for young people, the region and the sport of sailing in the UK."
