The CalMac ferry MV Clansman is returning to service after extensive repairs.
Her absence required the company to move to an alternative timetable causing widespread disruption across its west coast routes.
The vessel, which had work completed on its propulsion system, will pick up services from Uig to Tarbert and Lochmaddy allowing the MV Hebrides to enter dry dock overhaul.
CalMac managing director Robbie Drummond said: “Everyone in the company is working hard to getting a full fleet back in service by May 23 and having the Clansman back is an important milestone towards achieving this.
“In the summer our fleet is fully deployed to meet the specified timetable, which means that there are no spare vessels to provide resilience in the event of a technical breakdown. The impact this loss has had on our communities is of deep regret to us.”
The first service the Clansman was due to sail was the 7.30pm Uig to Lochmaddy last night.
The vessel will again return to dry dock for a short period in June for the replacement of its tailshaft, a key part of the propulsion system. The company is working to minimise the impact on customers and will issue an update once dates are confirmed.
