Simplified Wreck Survey
Underwater Wreck Survey Details Position 51 46231 N 1 34985 E UK Hydrographic Office records show a submerged shipwreck located off the coast of the United Kingdom in the North Sea historical survey data indicates the wreck is largely intact with an iron hull measuring approximately 60 to 65 meters in length and 10 to 15 meters in width lying on a northeast to southwest orientation with a magnetic anomaly suggesting around 500 tonnes of iron content over decades of monitoring by the UKHO depth measurements over the obstruction have varied with general seabed depths ranging from 10 to 15 meters scour depths reaching up to 182 meters and least echo sounder depths recorded between 73 and 91 meters subsequent surveys noted the wreck became increasingly buried under sediment leading to classifications as a foul obstruction before eventually being recorded as dead or not located in later multibeam sonar searches
