MV Bute was a Clyde vehicle ferry built by Ailsa Shipbuilding Company and launched at their Troon yard on 28 September 1954. Designed as a "general purpose" vessel, she was part of a trio of ferries—alongside MV Arran and MV Cowal—ordered in 1951 to modernize the Clyde fleet. Measuring approximately 150 feet in length, she featured a car deck equipped with electric hoists and side-ramps, allowing vehicle loading from conventional piers regardless of tide conditions. The car lift had a capacity of 14 tons and could hold five average-sized cars, which were turned on two 14-foot turntables on the lift and an additional one at the front of the garage. An aft cargo hold was originally fitted with two 7-ton derricks for cargo handling, but these were removed in 1958, and the hold was plated over to expand the car deck. Passenger accommodations included a large lounge and tearoom situated above, with a bar below the car deck. The bridge was located above the upper deck, providing unobstructed forward views for navigation. Crew and officer quarters were positioned below the bridge and at the stern. In 1975, her lift-supports were extended, raising the hoist an extra four feet for service at Mallaig, and a side door was added in her side ramp to facilitate access to the small boats on the Small Isles run. MV Bute entered service on the Rothesay route in 1954 and spent most of her career on the Upper Clyde crossings, particularly serving the route between Wemyss Bay and Rothesay. She was part of a fleet that saw her working interchangeably with sister ships from 1957 onward. Her operations were limited by infrastructure developments, such as linkspans, which restricted her to certain routes by 1972. In December 1972, she was briefly chartered for the Oban to Lochaline route while MV Clansman was rebuilt. After the formation of CalMac management in 1973, MV Bute was repainted with the new red CalMac livery, marking her integration into the unified fleet. She also operated on various other duties, including transporting workers to oil rigs and maintaining the Armadale crossing during summers. Her final passenger sailing occurred on 21 October 1978, after which she was laid up in Greenock’s James Watt Dock. In 1979, she was sold to Greece, renamed Med Sun, and eventually broken up in 1984–85, marking the end of her 24-year service on the Clyde.
