SM UB-41

German Imperial Navy (German: Kaiserliche Marine) during World War I

Design

A

propeller shaft. She was capable of operating at depths of up to 50 metres (160 ft).^[2]

The submarine had a maximum surface speed of 9.15 knots (16.95 km/h; 10.53 mph) and a maximum submerged speed of 5.81 knots (10.76 km/h; 6.69 mph). 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). UB-41 was fitted with two 50 centimetres (20 in) torpedo tubes, four torpedoes, and one 8.8 cm (3.5 in) Uk L/30 deck gun. She had a complement of twenty-one crew members and two officers and a 42-second dive time.^[2]

Construction and career

The U-boat was ordered on 22 July 1915 and launched on 6 May 1916. She was commissioned into the German Imperial Navy on 25 August 1916 as SM UB-41.

The submarine sank eight ships in thirteen patrols. 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. UB-41 was reported missing on 5 October 1917. The same day, a large explosion was observed from the coast at Scarborough, England. 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.^[2]^[7]

Her wrecksite was discovered in 1989 and surveyed in 1997 and 2003. The vessel is broken into two sections, at degree angles laying on the starboard side, and showing signs of impact damage.[8]
