SeaWind Line was a subsidiary of the Finnish passenger shipping company Silja Line, later owned by the Estonian company Tallink. In 2010, the Sea Wind brand ceased to exist and the remaining ship, MS Sea Wind, was transferred to Tallink colours. MS Sea Wind is dedicated to cargo shipping only, operating also as a train ferry on the route Turku-Stockholm. The ship is one of the most important carriers of railway carriages between Finland and Sweden.
