CALMAC is operating a single vessel service between Gourock and Dunoon after one of its ferries was withdrawn from the route less than a week on from the completion of other repairs.

MV Argyll Flyer suffered a technical issue in her main engine early this morning, with the service being fully suspended until around 7am.

The vessel had returned to the route on Saturday last week following repairs to her starboard engine.

MV Ali Cat remains on the run but will be required to refuel this afternoon, causing the 1:05pm from Gourock and 1:35pm from Dunoon to be cancelled.

During this time, a shuttle bus will run to Western Ferries’ terminal.
