PS Sandown was a passenger vessel constructed in 1934 by William Denny and Brothers in Dumbarton, Scotland. She was built for the Southern Railway and launched on 1 May 1934, costing £39,850. The ship was designed to serve as a ferry on the Portsmouth to Ryde route, operating between the mainland and the Isle of Wight. She was one of two vessels commissioned by the Southern Railway, the other being the Ryde, and was primarily used for passenger transport across this route. The vessel featured a typical design for a ferry of her time, optimized for short-distance passenger service. Her service was interrupted by the outbreak of the Second World War, when she was requisitioned by the Admiralty and converted into a minesweeper, bearing the pennant number J.20. As part of her wartime service, she was assigned to the 10th Flotilla in the English Channel, serving as the senior officer’s vessel. Notably, on 27 May 1940, Sandown played a significant role in the Dunkirk evacuation, leading the flotilla as they evacuated troops from France. During this operation, she rescued a total of 1,861 men, including 250 from a grounded drifter on 1 June. After the evacuation, she continued operations independently, supporting key military campaigns such as the Normandy landings and the Battle of the Scheldt. In 1942, she was reconfigured as an anti-aircraft ship to bolster her combat capabilities. Following the conclusion of hostilities, PS Sandown was returned to her owners in 1945. She was later acquired by British Railways in 1948, continuing her service as a ferry. An example of her ongoing utility, she rescued her sister ship Ryde in 1954 when Ryde experienced mechanical issues, successfully towing her to Portsmouth Harbour. After over three decades of service, PS Sandown was scrapped in 1966, marking the end of her distinguished career. Her wartime service, especially her role in the Dunkirk evacuation, underscores her maritime significance.
