von Knorring (originally Jan Nieveen) is a passenger ship which was built in 1928 in the Netherlands and has been in continuous use.

The ship was originally named after the beurtvaart captain Jan Nieveen, who transported goods and passengers from the city of Groningen to Lemmer.

[2] The steamboat Jan Nieveen was built in 1928 at the Arnhemsche Scheepsbouw Maatschappij shipyard in Arnhem, the Netherlands, at a then-high price of 140,000 Dutch guilders.

It was ordered by the Groninger & Lemmer Stoomboot Maatschappij, a shipping line which had been founded in 1870 by the brothers Reint, Jan and Geert Nieveen.

[3] During the Second World War, the ship transported food from the northern Dutch provinces to Holland (in exchange for gold and silver) and horses, in accordance with the German occupiers.

Fourteen passengers and crew on the Groningen IV drowned when the ship sank, trapped when the collision blocked the door.

[citation needed] Increasing competition from road transport ended the beurtvaart era, and the Lemmer–Amsterdam route was discontinued in 1959.
