Isle of Arran

Three of its large ships have technical faults and four other ferries are away for scheduled maintenance or repairs.

Four major vessels are in overhaul while three more were out of service with technical issues across its network.

MV Glen Sannox and MV Glen Rosa are too large to berth at Ardrossan Harbour in its current set up.

MV Isle of Islay has been placed on standby after MV Glen Sannox was taken out of service due to an engine fault.

A warning light for one of the ship's main engines means sailings have been cancelled since Monday afternoon.

MSPs have been told the troubled CalMac vessel needs new propellors as part of multi-million pound repairs.

The two other ferries which normally serve the Arran route have been undergoing maintenance.
