The Steam Packet Company says it's making a number of changes to its timetabled sailings over the next week.
It says from today until next Tuesday, April 15, the Manxman or Ben-my-Chree crossings will be moved to avoid low tide in the harbour.
The company says the Department of Infrastructure will start more dredging work next week to address problems in Douglas.
And also next week the Manxman is undergoing a routine safety exercise which means the Ben my Chree will stand in for her.
