Great Moor Sailing Club is situated on Grebe Lake near Calvert in the North Buckinghamshire Countryside. It is a friendly, family oriented sailing and windsurfing club founded 35 years ago. The club is 5 miles south of Buckingham, 10 miles north east of Aylesbury and 5 miles east of Bicester. The man made lake was formed from the closure of a brickworks clay pit and offers 65 acres of deep, constant level freshwater. The well developed woodlands around the lake offer pleasant walking for nature lovers and birdwatchers.
The club provides opportunities for a wide variety of water based activities such as dinghy sailing, sailboarding, fishing, scuba diving and canoeing. The sailing lake is home to a wide variety of bird life and a similar size lake close by is a designated nature reserve. The club successfully purchased the freehold to the lake and surroundings in 1999 and work is due to start shortly on refurbishment of the clubhouse which will include a new enlarged club room, classroom and changing rooms.
