Simplified Wreck Survey
Underwater obstruction located in the Thames Estuary off the coast of Kent at coordinates 51 22.171 N, 001 01.445 E. This site consists of a heavily broken-up and scattered wreck lying on a north-south orientation. The obstruction is classified as foul ground with a least depth of 0.35 meters, drying 0.35 meters in a general depth of 1.1 meters. The wreckage measures approximately 31.3 meters in length and 8.9 meters in width, standing 0.75 meters above the seabed. Survey data indicates a strong magnetic anomaly at the site, consistent with scattered metallic debris and remains. Although the area was historically marked by a green can buoy, all navigational markers have been removed. The site remains charted as foul ground due to the persistent presence of wreckage on the seabed.
