Voyages of Discovery has been forced to cancel a departure on Sunday due to power failures on the ship 15,300 gross ton Voyager, Travel Weekly reports in a daily newsletter emailed to Cruise Business in the UK.

 “A 10-day Heritage of the British Isles cruise due to depart from Portsmouth has been cancelled following the problems on the vessel on Tuesday,” the report said. This follows the abandonment of the current nine-day cruise to Ireland due to “unusual and unforeseen technical problems” with two of the four generators on board.

Voyages of Discovery, which is part of the Hertfordshire based All Leisure group, was cited as saying it was contacting passengers booked on the June 2 cruise and any affected trade partners. Passengers will receive a full refund, or the option to receive credit towards another booking for a cruise on MV Voyager to the value of 140% of their original fare.

Travel arrangements are being made to return all 487 passengers on board the vessel in Killybegs, County Donegal to Portsmouth, where the current cruise originated. “Specialist engineers are working hard to repair the affected generators. Voyager will remain in Killybegs while these repairs continue,” the company said.

The ship was built in 1990 as Crown Monarch for the now defunct Crown Cruise Line, after which it has seen service under many houseflags. It entered service with Voyages of Discovery last autumn after a refit.
