PARTREDERIET BRODRENE AARSETH.

The funnel is apparently based on a line drawing of the first vessel, Aril, built in 1961.

Modern Brødrene Aarseth fish-export businesses and unrelated people or boats were excluded. Lack of online evidence does not contradict the Norway assignment. The source consistently identifies Partrederiet Brødrene Aarseth of Torvastad and its vessels Aril and Ronita. Exact-name, vessel and location searches did not return a usable independent match.
