Realising that [[Roll-on/roll-off|car-passenger]] [[ferry|ferries]] would be the dominant traffic form in the future, the three collaborating companies decided to form a daughter company, {{Lang|fi|Oy Siljavarustamo}}''/''{{Lang|sv|Siljarederiet Ab}}.<ref name="Siljavarustamo">{{in lang|fi}} [http://www.valkeatlaivat.net/historia/siljavarustamo_perustetaan.htm Valkeat laivat: Siljavarustamo perustetaan] {{webarchive|url=https://web.archive.org/web/20071006132807/http://www.valkeatlaivat.net/historia/siljavarustamo_perustetaan.htm |date=2007-10-06 }}, retrieved 9 October 2007</ref> The new company started out with used ships, which were not particularly well-fitted for the role they were meant for,<ref name="Siljavarustamo" /> but in 1961 Silja took delivery of the new {{MS|Skandia|1961|6}}, the first purpose-built car-passenger ferry in the northern [[Baltic Sea]].

Despite the establishment of Silja, FÅA, Bore and Svea also continued to operate on the same routes with their own ships. This led to a somewhat complex situation where four different companies were marketed as one entity. In Finland they went by the name {{Lang|fi|Ruotsinlaivat}} ('Sweden's Ships' or 'Ships to Sweden') whereas in Sweden the preferred terms were {{Lang|sv|Det Samseglande}} (roughly 'the ones that sail together'), {{Lang|sv|Finlandsbåten}} ('Finland's Ships') or {{Lang|sv|Sverigebåten}} ('Sweden Ships'). In both countries the names of all four companies were usually displayed alongside the group identity.<ref>Malmberg & Stampehl (2007): page 108</ref>
