Sailings tonight and tomorrow have been cancelled due to forecast poor weather.
The 7.45pm Ben-my-Chree service tonight to Heysham and its return tomorrow at 2.15am have been called off, ahead of expected gale force winds.
Meanwhile, the 8.45am Heysham crossing on Tuesday and its return planned for 2.15pm are also in doubt.
A final verdict on those will be made no later than 7am tomorrow morning.
