(Europa often stayed in port over night, as did Saga Sapphire.)
Another ship that looked good from any angle was HMY Britannia. By coincidence it was in Halifax shortly before the night shot of the Europa, and with the negative only two frames away, I had to scan it too.
Laid down by John Brown Co in 1952, launched in 1953 and commissioned in 1954 it served HM The Queen and family until it was finally decommissioned in 1997. It has been preserved in Leith, Scotland and is one of Edinburgh's most popular attractions. No wonder.
