Engadine was the second of two turbine steamers delivered by William Denny & Son for the Dover - Calais service of the SECR in 1911. Like her sister, Riviera, she had a clear after deck, specially reinforced, for the carriage of motor cars.
Requisitioned at the outbreak of World War I Riviera was hurriedly converted to carry seaplanes at Chatham dockyard. Initially fitted with two rather unsatisfactory canvas shelters, during a more protracted refit at Belfast a year later, she was given a more substantial steel structure incorporating two cranes for the hoisting inboard and outboard of her complement of four Short Type 74 and Type 81 aircraft. Engadine participated in the battle of Jutland, making history by being the the first ship to launch an aircraft during a naval engagement.
Released by the Admiralty in 1920, Engadine resumed service with her sister Riviera on the Folkestone - Boulogne run until 1925 when she was placed in reserve after the delivery of two new vessels, Isle of Thanet and Maid of Kent. In 1932 she was chartered to Instone Lines who ran daily excursions from Tower Pier to the Nore lightship. Returned to the SECR at the end of the summer season she was laid up at Dover. The following year she was sold to a Philippine shipping company and renamed Corregidor.
During the Japanese invasion of the Philippines Corrigador struck a mine and sank in Manilla Bay.
