MV Isle of Mull is one of the larger ferries operated by Caledonian MacBrayne from Oban on the west of Scotland.

The new length of hull made the vessel better both in terms of vehicle capacity (taking it to around 80) but also in that she handled better at sea with her overall speed increased slightly.

[2] She completes the sailing in 45 minutes on a good day, although the short turnaround and poor manoeuvrability in even light winds lead to frequent delays and increased cancellations.

In October 1989, her larger passenger capacity was required at Stornoway for those travelling to the Mòd, while Suilven covered the Oban to Craignure service for 10 days.

During this time, she operated an amended timetable incorporating sailings to Castlebay due to a technical fault with Isle of Lewis.

Isle of Mull has also provided emergency services to Islay, usually sailing to and from Port Askaig, whilst also calling at Colonsay in each direction if required.

[5][6][7] In August 2022, Isle of Mull made her first full appearance on the triangle connecting Uig, Lochmaddy and Tarbert, while Hebrides underwent repairs to her firefighting equipment.

[citation needed] In April 2024, however, following redevelopment works at Uig Pier, it was confirmed that Isle of Mull can no longer operate regularly from there due to tidal constraints.

[8] On 28 December 2024, it was announced that the marine evacuation system had failed on Isle of Mull, with CalMac warning that the subsequent repair could take months.
