Simplified Wreck Survey

The underwater wreck of the vessel possibly identified as the POLESLEY is located off the coast of Pendeen, Cornwall, at coordinates 50 13.9 N, 5 46.041 W. Survey data confirms the wreck lies in a general depth of 44.8 meters with a least multibeam depth of 38.76 meters. The wreck is oriented on a 015/195 degree axis and measures 74 meters in length, 12 meters in width, and 6.4 meters in height. Structural observations indicate the vessel is intact but collapsed, accompanied by a 0.4-meter deep scour and a strong magnetic anomaly. Historical records trace the wreck's documentation back to 1918, with significant hydrographic surveys conducted in 1977 and 2009 confirming its precise position and identifying it as a maritime obstruction of interest near Pendeen Light.
