[Note 1] The submarine sank 36 ships in 17 patrols for a total of 47,107 gross register tons (GRT).
[5] UB-29 was supposedly sunk by two depth charges from HMS Landrail south of Goodwin Sands at 51°9′N 1°46′E / 51.150°N 1.767°E / 51.150; 1.767 on 13 December 1916 ,[2] although the location of its wreck discovered in Belgian waters, approximately 15 nm NW of Ostend, contradicts this claim.
[6] The UB-29's wreckage – exceptionally well preserved and with the hull still intact – was found by Belgian divers in the summer of 2017, and formally identified in November 2017.
The submarine was powered by two Benz six-cylinder diesel engines producing a total 267 metric horsepower (263 shp; 196 kW), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft.
Only some minor artefacts lying outside the submarine will be salvaged for an exposition in Belgium and will later be handed to the Internationales Maritimes Museum Hamburg.
