Heysham sailings this morning and this afternoon will depart earlier than usual.
The crossing originally scheduled for 8.45am will now set off at 8.15am - meanwhile its return previously planned for 2.15pm will now depart at 1.45pm.
This is due to recent poor weather causing additional silting at Heysham Port.
The Steam Packet Company announced alterations to its schedules on Tuesday - full information is on its website.
