MV Isle of Arran making her way down West Loch Tarbert to Islay.
Maid of Cumbrae was the last of a quartet of passenger vessels ordered in 1951 to modernise the Clyde fleet. She was built by Ardrossan Dockyard Ltd. As demand switched from short cruises to car ferries, in 1972, she was converted to operate as a 15-car ferry. She operated in this configuration for three years and was then sold in 1978, for a new career in the Adriatic.
