A breakdown on 17 June 2010 took "Clansman" out of service for crankshaft repairs and problems found during reassembly of the engine resulted in an extended disruption to services. CalMac tried to arrange a replacement vessel, but none could be found for lease. Out of action for six weeks, "Clansman" returned to service later in the summer and ran extra services in August for the Barra Fest music festival. However, she broke down again en route to Barra after the port engine developed a fault. Repair was effected quickly, but the event caused further disruption at the busiest time of the year.
