Small Panama-registered ISVANIA is here seen at Aabenraa, Denmark, in July 1981.
This vessel was built 1938 as FRYKEN by Aalborg Værft, Denmark for Ångfartygs AB Ferm, a company within the once large Broström-group.
Sold 1961 to Finland and renamed SVANÖ, and in 1971 she became Panama-flagged ISVANIA.

In 1986 she was renamed FRYKEN again, and was taken in use as a museum vessel in Gothenburg.
