The Steam Packet Company says a number of its sailings are being rescheduled because of expected severe gales this weekend.
On Friday, the Manxman's 8am Douglas to Heysham sailing will now leave at 7.30am, with her return trip at 1.45pm now leaving Lancashire at 1pm.
A decision on her 7.15pm Douglas to Heysham crossing and 1.45am Saturday return will be made by 5pm tomorrow.
The Manannan's Liverpool voyage at 3pm, meanwhile, will now be leaving the Island at 7am, while her return leg will leave at 11.30am instead of 7.15pm.
All of Saturday's crossings are also at risk of disruption.
The changes are being made as Storm Amy approaches, with winds expected to reach up to 65mph.
