A nine-day cruise has been called to a halt after two generators failed while the liner was visiting Killybegs.
MV Voyager docked at Killybegs on Tuesday morning with 487 passengers.
The ship was due to leave at 8pm on Tuesday but the departure was postponed after two of the ship’s four generators failed twice - at 2.45pm and 6.30pm.
Specialist engineers were not able to solve the problem.
A spokesperson for tour operator Voyages of Discovery said it was with “great regret” that the decision to cancel the remainder of the cruise, which was due to end on Sunday, was made.
All passengers will be flown back to Portsmouth tomorrow. They will receive a 60% refund of their fare and have also been offered a 50% discount on a future cruise onboard the ship.
The ship’s two remaining generators have remained fully functional, with all passenger faciities unaffected.
Additional excursions have been arranged for passengers during their extended stay in Killybegs.
The company spokesperson stated: “Voyages of Discovery has apologised to all passengers for these unusual and unforeseen circumstances which have arisen as a result of events beyond their control.”
