Knarr

A knarr is a type of Rjurik merchant ship of the same clinker-built method used to construct longships. It is generally used as a cargo ship.
The hull frame of a knarr is shorter, wider, heavier, and has a deeper draft than the longship. It is a square rigged, single masted trading vessel that relies primarily on its single square sail for propulsion at sea. It is usually half-decked and typically features the traditional built-up castle at the stern and a carved stern and sternposts. The square sail rig and lack of keel give the knarr a poor performance against the wind.
