The ship was built by William Denny and Brothers in Dumbarton and launched on 1 May 1934[2] by Mrs E.J. Missenden, wife of the manager for the Southern Railway Company Docks at Southampton.[3] Costing £39,850, she was one of two ships placed by the railway company, the other being Ryde.[4] She was deployed on the Portsmouth to Ryde ferry service.
At the outbreak of the Second World War, she was requisitioned by the Admiralty and converted to a minesweeper with the pennant number J.20, initially serving with the 10th Flotilla in the English Channel as the senior officer's vessel. On 27 May 1940, Sandown led the flotilla to the Dunkirk evacuation, returning with them on the following day and then operating independently. On 1 June, she rescued 250 men from a grounded drifter. The total number of men rescued by Sandown during the operation was 1,861. In 1942, she was reequipped as an anti-aircraft ship, later supporting the Normandy landings and the Battle of the Scheldt. She was returned to her owners in 1945.[5]
She was acquired by British Railways in 1948. On 30 June 1954, she went to the rescue of her sister ship Ryde which had mechanical difficulties. The Sandown managed to secure a tow line and tow her to Portsmouth Harbour.[6]
She was scrapped in 1966.
