For some ridiculous reason the last 53B off the port is 19:05, despite the 17:15 ex Holyhead Jonathon Swift arriving 10 minutes later.

This is simply not true & not the first time for mischevious statements.

Route 53B is specifically designed for foot passengers of the Ulysses & Swift, waiting outside Terminal 1 for passengers & Irish Ferries staff, the times quoted are for indication only.
