Further changes have been made to the Ben-my-Chree's repair schedule, meaning more sailings will be affected.
The Steam Packet's flagship will now go in to dry dock on Friday, and will not return to service until Tuesday next week.
The weekend crossings have been diverted to Heysham, as the replacement vessel, the viking, cannot dock at Twelve Quays in Birkenhead.
Passengers travelling between Friday and Tuesday are advised to contact the Steam Packet Company for a transfer or refund.
