Simplified Wreck Survey
Wreck of German submarine U-1020 located in the North Sea off the east coast of Scotland at coordinates 56 32.684 N, 1 18.892 W. This Type VIIC/41 submarine was lost in January 1945 after striking a mine in British minefield SN 17. The wreck lies at a depth of approximately 57 to 65 meters. The vessel measures 62 meters in length and 10 meters in width, with a height of 4.9 meters. It rests on the seabed with a 45-degree list to the port side and is oriented on an 080/260 degree heading with the bow facing east. The structural condition is generally intact, though the stern appears partially detached and damaged, consistent with torpedo or mine impact. Key identifying features include a raised attack periscope, a snorkel configuration, and life raft containers on the port side. The conning tower, torpedo loading hatch, and after hatches remain open. A scour of 2 meters is present on the east and south sides of the wreck site.
