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.
However, the Swedish krona was devaluated shortly before Slite were supposed to take delivery of the new ship.
