The Steam Packet Company says this morning's Manxman sailing to Heysham will be delayed by at least 15 minutes.
The vessel was scheduled to set off from Douglas at 8.45am, but in a statement the company says she will now leave port at 9am.
Last night, the company brought in the Ben my Chree for an extra freight and goods sailing to allow the Manxman to carry as many passengers as possible.
It's after a week of disruption to sailings on the Steam Packet company's newest ferry.
