The island’s newest ferry will not undertake night-time services in its first month of operation.
The Manxman, which arrived earlier this month, is set to take over sailings between the island and Lancashire.
The Isle of Man Steam Packet has said it will only operate the 08:45 BST sailing from Douglas to Heysham, and the 14:15 return for the first four weeks of operation.
A date has not yet been set for the vessel’s maiden voyage.
Evening sailings and their overnight returns will continue to be operated by the Ben-my-Chree.
