Changes have been made to tonight's Ben-my-Chree crossing to Heysham and it's return early tomorrow morning.
The 7.45pm service will now set off at 9pm, meanwhile the 2.15am return on Tuesday is now expected to leave at 3.15am.
The Steam Packet Company says this is due to the ongoing silting issues continuing to affect the Lancashire port.
Passengers are being reminded to check in no later than 8.15pm and 2.30am respectively.
