The Hansa class is a class of four ro-pax ferries originally built by Stocznia Gdańska, Poland for Finncarriers-Poseidon service. Following a merger of Finncarriers and Poseidon to Finnlines, all ships of this class came to be owned by Finnlines. As of 2013, three ships (Finnpartner and Finntrader) are operated on Finnlines' routes connecting Finland and Sweden to Germany, while two ships (Euroferry Sicilia, Euroferry Olympia) sail with Grimaldi Ferries in the Mediterranean Sea.
