CalMac is struggling to put together a service for passengers leaving or arriving on Barra this week, after the MV Isle of Lewis was shipped off to Clydeside for urgent repairs.

The timetable between Castlebay and Oban has been patchy over past days, with technical problems on the ageing ferry scrambling the timetable.

On Friday (July 19th) another breakdown left the operators with no choice but to take her off the route.

With the Isle of Lewis now in drydock at Greenock, CalMac is patching together a service using the MV Isle of Arran, with a smaller capacity than the Isle of Lewis, to relieve some of the log-jam between Castlebay and Oban.

Meanwhile MV Lord of the Isles was also operated on an additional run today (Sunday) between Lochboisdale and Mallaig.

Customers were re-routed via the Sound of Barra service to use that service.

But with worsening weather forecast for tomorrow (Monday July 22nd) and Sound of Barra services already cancelled this evening, CalMac say: “Due to the weather forecast and the technical issue with MV Isle of Lewis, the following amended timetable will be operated by MV Isle of Arran:

“Depart Castlebay - 04:00 (Early 07:55 departure, revised from previous time of 06:00)

"Arrive Oban - 09:30.

The departure time for the scheduled 13:30 sailing is still to be confirmed and we will provide an update by approx 19:00 today.

“Due to tomorrow’s weather conditions, it will not be possible to provide any extra sailings on the Mallaig-Lochboisdale service to provide additional capacity to Barra.”
