The Steam Packet Company says its sailings may be delayed because of fog this morning.
The Ben my Chree was due to set out from Douglas for Heysham at 8.45am.
However, on its website, the company says there may be a delay to the trip to Lancashire - fog in Heysham means the vessel couldn't dock on time there, leading to knock-on delays.
It’s asking passengers to check in as normal.
