Originally the Finnhansa sailed on the route Helsinki (Finland) — Nynäshamn (Sweden) — Karlskrona (Sweden) — Lübeck (Germany) — Slite (Sweden) — Helsinki carrying up to 1424 passengers, but after a few years the route was simplified into Helsinki — Nynäshamn — Travemünde. During summer 1967 the ship made weekend cruises from Lübeck to Rønne (Denmark) and Helsinki to Sandhamn. In 1970 the Finnhansa, along with the entirety of Finnlines, was sold to the Finnish paper industry giant Enso-Gutzeit. In spring 1972 the ship was rebuilt at Howaldtswerke-Deutsche Werft, Kiel, Germany with 288 new cabin places. Additional rebuilding followed in spring 1973, when the ship's restaurant deck was rebuilt and the outside pool from her aft deck was removed.
