Gale force winds predicted
There are more strong winds on the way, leading to Wednesday morning's sailing to Heysham being pulled back by an hour and a quarter.
Instead of its usual sailing time of 8:45am, the Ben My Chree will set off at 7:30am.
Passengers should board no later than 7am tomorrow morning.
The return crossing is also sailing earlier than scheduled to get ahead of the strong winds.
A severe gale force nine is being predicted by the met office.
The Ben will depart from Heysham at 12:30pm, with passengers asked to arrive no later than 12 noon.
