All but one of this weekend's sailings are subject to possible disruption or cancellation.
Saturday's 8am, 2pm and 7:45pm Manxman crossings are all in doubt due to the weather forecast.
This also applies to all of Sunday's sailings and Monday's overnight journey.
A decision on Saturday's 8am journey to Heysham and it's afternoon return will be made by 6:30am on the day.
