MV Orpheus was a cruise ship launched on 25 March 1947 and completed on 17 January 1948 by the shipyard Harland and Wolff in Belfast as Munster for B&I Line. It replaced the earlier Munster, built in 1938, which sank in 1940. By 1967, the ship, onto which cars were loaded by crane, began to look dated compared to newer ships of the roll-on/roll-off variety. It was sold in 1969 to Epirotiki Lines. Orpheus was relocated to the Americas where it sailed in Alaska, Mexico, and Panama for about one year. It was then relocated to Greece and operated in the Mediterranean.
