Oselver tolværing (river Os 12-oars boat) from Os, Norway, 1999

Boats similar to the Oselver tolværing (River Os 12-oar boat), were used up to about 1900 for fishing cod with nets on the open sea off Western Norway. They were so fast and seaworthy that they could almost always reach the lee of land before storms gathered. Oselven was built by Harald Dalland in Os in 1999 specially for sailing with schoolchildren on Roskilde Fjord.

The garboard strake is more horizontal on Oselven than it is on Bjørnefjord, giving Oselven better bearing on open sea, while Bjørnefjord is better suited to calmer waters.
