The submarine was powered by two Körting six-cylinder diesel engines producing a total 284 metric horsepower (280 shp; 209 kW), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft.

When submerged, she could operate for 45 nautical miles (83 km; 52 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 6,450 nautical miles (11,950 km; 7,420 mi) at 5 knots (9.3 km/h; 5.8 mph).

They included the William Cory and Son collier SS Harrow, which UB-41 torpedoed in the North Sea off Robin Hood's Bay on 8 September 1917.

The case of her loss was either an internal explosion, or she struck a mine, possibly a German one, and sank in the North Sea on 5 October 1917.

The vessel is broken into two sections, at degree angles laying on the starboard side, and showing signs of impact damage.
