Condor Ferries has cancelled or delayed a number of services from next week due to engine failure on one of its high speed vessels.
Condor Vitesse is due to be dry-docked for two weeks from Sunday for one of its four engines to be replaced.
Some services between the Channel Islands, France and the UK have been rescheduled and 10 services between Poole and Cherbourg have been cancelled.
Among the cancelled sailings are departures next Monday, Wednesday and Thursday while others have been rescheduled.
The company website says that Condor Vitesse is being withdrawn from service next week due to a technical problem.
Condor Ferries said it was working to help those passengers affected make changes to their travel plans.
Condor’s Guernsey director Ian Milner told the BBC: “We have made the decision to fit a new engine before the peak summer season begins in order to avoid disrupting the majority of passengers.
“We do have access to a reserve engine and this has considerably reduced the length of time that the ferry is out of the water, but the replacement will take approximately two weeks to fit.”
Further rescheduling is expected for a trial period after the new engine is fitted.
