Hi - I met Percy Danks once. He used to run tours to join the cruises to Norway and Morocco aboard TS Avalon, the Harwich-Hook ferry. Avalon was used for cruises once she became the spare ship. She was an oil-guzzler and was, unfortunately, out of date when she was launched. British Rail (later Sealink) ran several cruises with sailings from Harwich. Percy and my father, who was captain of the Avalon, became good friends.
