Broken-down Pentland Firth ferry Hamnavoe faces new problem
The broken-down ferry which was taken off the Orkney to Scrabster service has been hit by further problems.
It was expected that the Hamnavoe, which sails from Stromness, would be back in service across the Pentland Firth on Tuesday.
However new engine checks have now revealed damage to the vibration damper.
Operators Serco NorthLink estimated Hamnavoe would return to service on Thursday.
They apologised to customers for the ongoing inconvenience.
Hamnavoe had suffered a crankshaft failure last month.
Orkney MSP Liam McArthur said: "This is disappointing news and risks creating further confusion for those planning to travel over the next couple of days."
He added: "More generally, however, lessons must now be learned for the future, particularly around contingency planning and communications with the public."
