imagine having to do an overnight trip in the north sea on one of them! the ferry to the Shetland isles was an old cross channel ferry(can't remember the b1oody name of it!) that would leave Aberdeen at 7pm & arrive in Lerwick at 7am. 1st time i traveled on it was just plain scary, more like a 12 hr ride on a roller coaster than a boat trip. its not like i wasn't used to ferry travel either,having at 1 point, 5 uncles working on the cross channel ferries out of Dover & Folkestone.
the trips from Shetland in the school holidays were great though,as us nippers would run riot on the boat as our parents went & got p1ssed in the bars
