Simplified Wreck Survey

Unidentified underwater wreck and obstruction located off the south coast of England at coordinates 50 26.598 N, 0 44.109 W. This square-shaped submerged structure features dimensions of approximately 20 meters in length and 12 meters in width, rising to a least echo sounder depth of 61.4 meters within a general surrounding depth of 64 meters. Examined using DGPS, the site displays a distinct square profile with one collapsed corner, no surrounding seabed scour, and a very poor magnetic anomaly. Historically noted as potentially resembling a Mulberry harbour type unit, current hydrographic survey data classifies the site as a 61-meter obstruction.
