This is a picture of HNoMS Oster right after the Germans captured it, and it is therefore in German colour/markings. The germans did not modify this until 1944, and this is the original Norwegian configuration. we should be able to see a difference between the German 1944 modification, as they removed some of the masts and replaced them with new ones

HISTORY
The ship was built and delivered to A/S Indre Nordhordlands Dampskibsselskab (B.Samuelsen) Bergen and named Oster. In 1915, the ship was lengthened and various modifications were made there, it was then given the dimensions stated in the proposal. in 1921 it was transferred to A/S Indre Nordhordlands Dampskibsselskab, Bergen and in 1926 transferred to Indre Nordhordlands Dampbaatlag L/L, Bergen. the ship was there until it was requisitioned in 1939 by the Royal Norwegian Navy

Before the Second World War, half of the people in Hordaland, Norway had only the sea as their means of communication with the outside world. In other large parts of the county, the road standard was actually so poor that the sea route was the most used route. and it therefore had very serious consequences when six steamboats were requisitioned by the Royal Norwegian Navy and which were later hijacked by the Germans during the war

Cannons on Steamships
In September 1939, the navy requisitioned six steamships. These steamships were to do guard duty for the Royal Norwegian Navy, and cannons were therefore mounted on the steamships. The steamships that were requisitioned were; “Lindaas” from Lindaas-Masfjorden, “Haus” and “Oster” from Indre Nordhordland, “Øygar” from Hjelma and Herdla, and “Alversund” and “Manger” from Alversund and Manger.

When Norway was invaded by Germany on 9 April 1940, these ships were on post. These then reported enemy attacks, and some of the ships, such as “Haus” and “Øygar”, later took part in battles, and “Øygar” was nearly sunk in one of these battles. “Alversund” was sunk by its own crew in an attempt to avoid it falling into the hands of the enemy, but was soon raised by the Germans. The Germans eventually confiscated all these boats during the war.

These ships were the glue between village and town in these areas, as both people, cattle, foodstuffs, dairy products and much else were transported via these ships, and they were also the biggest collective travel offer at that time here. The route offer was seriously weakened in 1939 when they were requisitioned, and weakened even more when the Germans took these ships in addition to a number of others during the war. this was the case for a long time after the war as well, because the Germans damaged the ships so much that they had to be repaired and modernized at the same time.

In the same month that Germany invaded Poland, Oster was requisitioned by the Norwegian Navy and fitted with a 76mm L/50 Bofors gun which was mounted on the foredeck with a platform. On the evening of 8 April, Oster was ordered to patrol the southern part of the Hjeltefjorden, and was then ordered to Blomvåg in intelligence and liaison functions. On 6 May 1940, the ship was abandoned by the Norwegian crew in Telavåg. The German navy did not find the ship until 22 May and took over the ship then, at first no modifications were made to Oster other than that they gave the ship a new name “Marder” which in folk German should mean “Tjuvradd” (Thief).

The ship went into German service as a patrol ship, until it was modified in the spring of 1944. The forward and aft masts of the ship were removed, this was to fit a new unit mast on the bridge and make room for a new 37mm gun, which was placed on a platform between the bridge and the 76mm gun on the foredeck. A rack for sinking mines was also mounted on the aft deck.

When the Germans capitulated, the ship was abandoned in Norway at Telavåg. The ship had been used hard during the war and was therefore well worn, and required extensive repairs and maintenance by Norwegian shipping companies.

IN GAME
Well, the speed is not great but the manouverability should be better, and the armament is far from bad. I believe this would work in a regular techtree.
