Loch Fyne entered service at Kyle of Lochalsh on 12 September 1991, replacing the last of the old ferries, MV Kyleakin.

Loch Fyne proved successful and became the permanent vessel on Mull's secondary crossing, having sufficient capacity to cope with all but the busiest days there.

Passenger accommodation along the starboard side of the hull can cater for up to 250 persons, with lounges on two levels and an open deck above.

In November 2016, Loch Fyne carried out further berthing trials on the Mallaig to Armadale route, causing rumours that she was going to take over from MV Lochinvar.

Loch Fyne became the primary vessel on the Mallaig to Armadale route on 31 March 2017, with MV Lord of the Isles carrying out additional sailings between her roster to Lochboisdale.
