MS Sea Wind is dedicated to cargo shipping only, operating also as a train ferry on the route Turku-Stockholm.

[1] SeaWind was founded in 1988 and started trafficking Stockholm–Turku with MS Sea Wind on 21 April 1989.

In order to keep tax-free sales on board after the EU changed its tax free legislation, a stop at Långnäs was added to the route in 1999.

Between the years 2002 and 2005 SeaWind's MS Star Wind served on the route Helsinki–Tallinn.

[1] In January 2008, SeaWind Line ceased carrying passenger traffic.
