Possible disruption for crossings on Sunday night and Monday morning
Sailings to and from Heysham tomorrow (16 October) are now set to depart earlier than previously scheduled.
Sunday's 8.45am Ben-my-Chree service to the Lancashire port will now get underway at 8.15am - passengers are asked to check-in no later than 7.45am.
Meanwhile, its return at 2.15pm will now leave at 1.30pm - passengers should check-in no later than 1pm.
The changes are due to forecast poor weather.
Meanwhile, Sunday's 8pm Ben-my-Chree voyage to Heysham and its return at 2.15am on Monday, 17 October, are subject to possible delays or cancellations due to the expected poor weather.
A final decision on those crossings will be made by 5.30pm tomorrow (16 October).
Tomorrow's Manannan services to and from Liverpool at 3pm and 7.15pm are currently scheduled to take place as normal.
