The Loch Tarbert is a small roro ferry that is currently owned and operated by the Scottish ferry company Caledonia MacBrayne. She was built in 1992 by JW Miller and Sons Ltd., Scotland for the company. She has operated on the seasonal route that links Lochranza with Claonaig for her entire career, replacing the Loch Ranza. She opened the new route linking Otternish with Leverburgh in 1996, filling in until the arrival of the newly built Loch Bhrusda later that year. In 2000, a strike prompted in passengers being diverted to the Lochranza-Claonaig route. Because the traffic was so vast, the vessel Isle of Cumbrae was temporarily taken off of her route between Tarbert and Portavadie route to assist the Loch Tarbert. The vessel has no sister ships. Her current port of registry is Glasgow, Scotland, United Kingdom.
