One Steam Packet sailing has been brought forward today (18 Dec) because of the bad weather.
This afternoon's Heysham to Douglas sailing will depart 45 minutes early at 1.30pm.
The Ben-my-Chree's following two voyages - 7.45pm Douglas to Heysham and tomorrow's 2.15am return - may be subject to disruption or cancellation.
A decision on both is due to be made by 4pm.
