With your choice of name your interest could be Matson Line.
So you may know that Queen Frederica started her career as Malola in 1937 for Matson Line. 1938 they changed her name to Matsonia.
Matson sold her in 1948 to Home Lines and she was renamed Atlantic, she was renamed again in 1955 as Queen Frederica while still with Home Lines who sold her to Chandris Lines in 1966 and they retained the name.
She was laid up at Piraeus 1971 and broken up in 1977
I won't question that as my info seems to come from a write up from Chandris Lines on Queen Frederica.
In fact I find that Matson seem to disregard this ship in their history write up in the same book.
Must be that she was not on the Australian Service
Malolo or as later renamed Matsonia were never on the Australian service so do not rate a mention in the book I have.
John, Chandris give her no more detail than Laid up at Piraeus 71, broken up 77, they must have lost interest in her.
Do you know if she did any work as Victoria.
John mentioned she left Dartmouth as Victoria, I asked if she had done any work as Victoria thinking I would look up its history 71 to 77, since then I have been to the same sites as you.
The Victoria as named and owned by Chandris 75 to 94 was 15,000 tons, Queen Frederica was 21,000 tons, one of those other sites I visited put Queen Frederica at 17,000 tons, majority suggests 21,000 tons so they could not be one and the same ship.
Dunnottar Castle built 1936 became Victoria with Icres lines 1958 to 1975, from 75 to 94 she was The Victoria with Chandris then Princesa Victoria as a cruise ship till 2004
The years 71 to 77 still remain grey areas.
71 or 72 they could have done a Blue Lady on her and moved her to lay up in Greece with an unofficial rename.
