Styrsöbolaget

Styrsöbolaget is a Swedish shipping line owned by Transdev Sverige AB. Styrsöbolaget operates maritime public transport in the Gothenburg archipelago and on the Göta älv river (on the "Älvsnabben" ferry line) on a commission from Västtrafik. In the southern archipelago the line also transports cargo. The passenger ships to the southern archipelago depart from Saltholmen, accessible by the Gothenburg tram line 11, and Ö-Snabben from the city centre. The cargo and car ships depart from Fiskebäck.

Styrsöbolaget was founded in 1922 under the name Styrsö Nya Trafik AB. In the same year Styrsö Havsbad began to drive its own traffic. These companies merged in 1928 into a joint company that developed into Styrsö Trafik AB. Since 1999 passenger traffic to the archipelago has been handled on a commission from Västtrafik, which is responsible for the public transport in the Västra Götaland Regional Council. Styrsöbolaget was privatised in summer 2000 and has been owned by Transdev Sverige since January 2004.

Traffic
Styrsöbolaget operates archipelago traffic on the routes Saltholmen-Asperö-Köpstadsö-Styrsö-Donsö-Vrångö, Styrsö-Källö-Vargö-Brännö at Husvik, Saltholmen-Aseprö-Brännö Rödsten and Saltholmen-Knarrholmen-Förö. Styrsöbolaget also operates traffic on Göta älv on the route Lilla Bommen-Stenpiren-Lindholmen-Slottsberget-Eriksberg-Klippan.

On normal weekdays in the archipelago traffic the express ships Valö and Rivö go to Vrångö. Ylva traffics to Styrsö Tången and Brannö Husvik, and through a few turns to Vrångö and some trips to Brännö Rödsten. Vesta traffics on mostly the same routes as Ylva. Silvertärnan traffics to Brännö Rödsten with some trips to Styrsö Tången, Brännö Husvik and Vrångö. Fröja and Vipan are reserve ships in case some ship is on the dock or cannot traffic for some other reason. Fröja is often used in place of the express ships, as she is larger and better suited for daily archipelago traffic, but still slower than the express ships. She has some trips of her own in both summer and winter. Vipan is older and narrower, but faster, so she is often used to replace the express ships. Vipan has trips of her own in summer, but in winter she is only a reserve ship for the express ships, without trips of her own. If there is need, Skarven, who has trafficked in the archipelago for 37 years from 1981 to 2018, can be moved to the archipelago. Skarven is used every year as reinforcement and can even travel under ice periods when the express ships cannot travel. As Skarven is made of aluminium she goes back to the river when the ice in the archipelago becomes too difficult for her to move in. In winter, Skarven is mostly used as a reserve ship for Älvsnabben.

Traffic on the river is handled by both Älvsnabben and cost-free commuter ships. Älvsnabben 4 and 5 usually handle the Älvsnabben traffic, with Älvsnabben 3 and Skarven as reserve ships. One of them starts at Klippan, the other at Lilla Bommen. Älvsnabben has traffic nearly throughout the day. The ships travel in the morning, in the day and in late evenings both on weekdays and on weekends. There is even a cost-free commuter line which only traffics on weekdays between Stenpiren and Lindhomspiren, on Älveli and Älvrfida. Älv-Vira is sometimes used as a reserve ship. The line is trafficked between morning and early evening.
