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.
