A cruise ship is basically a floating hotel. Depending on the severity of the storm, the crew probably did not want to be dealing with a significant number of sea-sick guests.
It used to be possible to take a berth on a cargo ship to/from Liverpool from/to Halifax. The modern equivalent is a ride on a container ship [1]. They will still avoid really bad storms but you are more likely to see some seas around autumn.
