Simplified Wreck Survey
Underwater wreck details for the site located at coordinates 52 19.773 N, 1 47.575 E off the coast of Suffolk, UK. This maritime obstruction is situated in the North Sea and has been subject to multiple hydrographic surveys since 1966. The wreck is currently classified as almost entirely buried with a least multibeam depth of 18.3 meters in a general seabed depth of 22 meters. Structural dimensions recorded during the 2017 survey confirm a length of 33.7 meters, a width of 9.6 meters, and a height of 2.1 meters above the seabed, with an orientation of 345/165 degrees. Historical records note the site was previously identified as two separate contacts, with later examinations suggesting a single vessel in one piece but structurally compromised or partially buried. A scour mark measuring 26.16 meters long and 1.13 meters deep has been documented trending towards 014 degrees. This site remains a significant underwater obstruction for navigation, consistently identified in modern hydrographic charts.
