Weser was a German fishing trawler that was requisitioned in the Second World War by the Kriegsmarine for use as a vorpostenboot.

It drove a single screw propeller via a low pressure turbine, double reduction gearing and a hydraulic coupling.

The fishing boat registration BX 267 was allocated,[3] as were the Code Letters DOUP.
