Three new car ferries were delivered to Coast Lines in 1966/67 to update the Irish Sea services. The third of these, Lion took over the Ardrossan - Belfast day service of Burns & Laird. She entered service on 3 January 1968. Two weeks later, she was damaged in a storm and was out of service for two weeks.
Lion was sold to European Ferries (Townsend Thoresen) in 1985, and then to Thenamaris Shipping for service in the Mediterranean. In 1987 and 1988, she was renamed Portelet for charters to British Channel Island Ferries; between charters, she was laid up in Weymouth.
On 24 February 1990, between Larneca and Greece, she came under fire from a gun-boat and was withdrawn for repairs. In 1997, she was sold to Equester Shipping, Kingstown, Saint Vincent & Grenadine. and left for service in Indonesia.
