The Steam Packet Company says problems with tide levels at Heysham will mean disruption for passengers over the course of the next week.
In a statement, the company says restricted water depths at the entrance to the Lancashire port and prevailing tidal conditions will affect sailings for up to eight days.

The company says it’s working with the Mersey Docks and Harbour Company to improve the situation, but is asking passengers to be patient.
