A ‘technical issue’ with the oft-damaged MV Glen Sannox’s port engine has resulted in the ship being sidelined for repairs, a week after it returned to service. 

As a result, ferries between Troon and Brodick, the main route between Arran and the West of Scotland, have been suspended for a second day.

CalMac has said that the most recent fault came after a spare part was fitted.

A spokesperson said that as the Glen Sannox approached Troon, "the oil mist detector alarm for the port main engine came on again".

A status update on CalMac’s website reads: “Following sea trials, the technical issue with MV Glen Sannox's Port Main engine has not been resolved.

“There will be a review by 17:00 for service from Wednesday 18 March.

“Disrupting a sailing is a decision we do not take lightly because we know it will inconvenience our customers and the communities we serve. We apologise for any inconvenience caused.”

Elsewhere, ferry journeys between Arran and Ardrossan were also cancelled on Tuesday due to weather restrictions as the MV Caledonian Isles returns to service.

The Glen Sannox entered service in January 2025, seven years later than expected, and significantly more expensive than expected. 

It has also been revealed that the ferry requires new propellers after just a year in service, which could cost as much as £3.2 million.
