I came across this picture of Highland Queen anchored off Nigg Scotland when both ships were serving as accommodation for oil rig workers. Here is the website:

I cannot get over how handsome these ships were during their Epirotiki days. It sounds as if they were quite successful however I suppose like many older vessels they were victims of the 70s fuel crisis. How I would love to have seen them again, but my first visit to Greece was in 1976...too late!
