The Steam Packet Company says this morning's Manxman sailing to Heysham, will leave later than planned.
The ferry firm says she was due to set off from Douglas at 8am but will now leave at 9.45am.
Most ferries have been cancelled until Sunday because of Storm Amy, with just two more sailings planned today.
The Manannan is due leave Douglas for Liverpool at 7am with her return journey at 11.30am - almost nine hours early.
All of Saturday's services have been cancelled in the face of severe gales, while a decision on the Manxman's 1.45am crossing from Heysham on Sunday will be made by 5pm on Saturday.
