The line’s Ambience was due to depart on a three-day Festive Market Getaway cruise from Tilbury on Sunday (18 December).
But after annual maintenance works were conducted, an issue with the ship’s onboard lifeboat station was identified, forcing the line to cancel the sailing.
In a statement, Ambassador said: "We have chosen to immediately address this as a precautionary measure and, as such, will not be able to complete the repair and post-repair test in time to successfully operate today’s sailing.
"It is never an easy decision to cancel any itinerary, particularly at this time of year, and we would like to apologise to all those guests who were due to sail with us today."
