The Steam Packet says tonight’s Heysham to Douglas will take longer due to insufficient water depths in Douglas.
This will also impact the morning sailing from the island to Lancashire.
Manxman will leave Heysham at 2:45am, but won’t arrive in Douglas until 8am on Saturday morning.
As a result, the 8:30am sailing is now scheduled to depart at 9:30am, with its return now expected to leave Heysham at 3:30pm.
The company said this is because of “insufficient water depths in Douglas port due to ongoing dredging issues”.
