Sailings scheduled for next week have been changed due to issues with low tides.
The Steam Packet Company said that sailings between Douglas and Heysham from May 6 - 11 are affected, as low tides in Douglas Port coincide with ferry departure and arrival times.
Due to a a berth depth of 5 meters, this is under the Sea Services Agreement obligation of 6.5m.
They said that the Ben-my-Chree will operate additional freight sailings on Wednesday and Thursday.
All passengers booked on sailings between these dates will be contacted by the SPC's reservation team to advise of any changes and apologise for any inconvenience caused.
