Simplified Wreck Survey
Underwater wreck located at coordinates 51 43.481 N, 1 33.144 E in the United Kingdom territorial waters. Historical hydrographic surveys spanning from 1952 to 1990 detail a deteriorating submerged obstruction lying within its own scour. The wreck is oriented along a 040/220 degree axis, with a measured length of 70 meters and a beam of 12 meters. Survey findings describe the site as broken-up and mostly contained within a scour depth of 6.3 meters, featuring a least echo sounder depth of 4.2 meters in a general depth of 4 meters. Seabed conditions consist of fine sand with strong magnetometer deflections noted during examinations.
