The MV Isle of Lewis developed a technical problem while en route to Ullapool from Stornoway yesterday (Thursday 11th).
Repairs are now underway and it is hoped the ship will return to service later today, although a spokesperson from CalMac said there are no guarantees.
Yesterday he explained there had been a technical problem on the starboard propulsion unit.
A passenger who was on the MV Isle of Lewis when it broke down said: “At about 3.00pm a call went out for ‘work party 1 to engine room’.
“Around ten minutes later the captain announced that there was a ‘catastrophic failure’ of the starboard engine but the ‘situation was contained’ and crew, passengers and ship were in no danger.”
He added: “We’re were then travelling at 10.5 knots on one engine.”
A CalMac spokesman explained: “Repairs are well underway and subject to successful sea trials the ship may be ready to return to service later today, but we cannot give guarantees at this stage. Investigations into the cause of the breakdown are continuing.
“In the meantime, traffic is being redirected via Tarbert and Uig. We apologise for any inconvenience caused.”
