Ben-my-Chree and Manannan have gone into dry dock as part of their planned survey schedules.
The Ben is due to return to regular service for the Steam Packet next year as part of a new enhanced service to the island of Ireland.
The company said: “Following completion, Ben-my-Chree will return to the island to provide cover for the IOMSPC during the Christmas and New Year period, while Manannan begins its winter lay-up and maintenance returning to service in March 2026.”
