Due to adverse weather conditions
Today's Steam Packet schedule features several sailings subject to possible disruption and/or cancellation.
It's been confirmed this morning's Ben-my-Chree sailing to Heysham at 8.45am is going ahead as planned.
A decision on this afternoon's Manannan crossing to Liverpool, and its return, is expected by 1pm.
This evening's Manxman trip to Heysham - and the return sailing in the early hours of Wednesday morning - could also be hit; a final decision on these services will be made by 6pm.
It's due to winds in the Irish Sea which are expected to reach up to gale force eight.
