Rearview of norsten

Found this swedish website. Will translate:
This vessel is a school-ship. It was buildt as a minesweeper for the swedish navy, the fishingboat-type. Was delivered in 1973, made of wood, the last navalship too be made of... Yeah, wood. In 1997 she was bought too strømstad, and got rebuildt too a school-vessel.

So there you have it. Training-ship?
