Manannan sailings tomorrow will set off earlier than previously planned.
The 10am service to Heysham will now depart at 9am whilst its return previously scheduled for 2.16pm will now get going at 1.15pm.
The Steam Packet Company says this is due to the poor weather being forecast during Friday.
Passengers are being asked to check in for the morning voyage no later than 8.30am and no later than 12.45pm for the afternoon crossing.
