Western Ferries started their route between Hunter’s Quay and McInroy’s point on Sunday 3rd June 1973. For the new service, the company introduced two former Swedish ferries with bow and stern loading, allowing straight through roll - on roll - off operation. Following a refit at Greenock the first ferry was renamed ‘Sound of Shuna’ and ran at hourly intervals throughout the day between 0700 and 2200. The second vessel, renamed ‘Sound of Scarba’, entered the service in July. In August 1974, they were joined by a third ship - the former Isle of Wight ferry ‘Lymington’ now called ‘Sound of Sanda’.

In April 1985 the company was restructured taking on its present title of Western Ferries (Clyde) Limited and soon afterwards, another ex-sea link ferry was purchased. She joined the fleet in June 1986 as ‘Sound of Seil’. Traffic was still expanding rapidly and in 1988 yet more tonnage was added in the shape of ‘Sound of Sleat’ - a ferry that had previously been used on a river crossing in Holland. By now Western Ferries was carrying significant amounts of the traffic between Cowal and Inverclyde. To cater for this, two further ferries were purchased from Dutch owners, joining the fleet in 1995 and 1996 respectively as the ‘Sound of Scalpay’ and ‘Sound of Sanda’. Both were re-engined and given thorough overhauls at Greenock before entering the service, replacing older tonnage. Loosely based on the design of the two most recent acquisitions by the company, Ferguson shipbuilders of Port Glasgow produced the second ‘Sound of Scarba’ in 2001 - the company’s first new ferry for the service. She was followed by a sister ship named ‘Sound of Shuna’, two years later. The company has a present capacity of four ferries carrying 140 cars per hour.
