The Steam Packet says bad weather tomorrow has put two more sailings at risk of disruption.
Today's sailings were all cancelled in the face of Storm Agnes, although the 2.15am Heysham to Douglas sailing with the Manxman is going ahead as planned.
However, Thursday's 2pm Douglas to Liverpool and 7.15pm return trip may be called off with more poor weather forecast.
A decision is expected to be made by midday tomorrow.
