Steam Packet sailings this morning and this afternoon have been cancelled.
The crossing to Heysham at 8.45am and its return at 2.15pm this afternoon won't go ahead due to poor weather.
It comes after sailings yesterday were called off owing to adverse conditions.
However, tonight's 7.45pm Ben-my-Chree service to the Lancashire port is currently due to depart as normal.
