Simplified Wreck Survey
The UK Hydrographic Office wreck of the German submarine U-671 is located off the coast of Beachy Head in the English Channel at coordinates 50 23.684 N, 0 19.081 E. Confirmed as a World War II Type VIIC U-boat, this historic underwater obstruction lies upright on a shingle seabed at a general depth of around 41 to 45 meters, with a least depth over the wreck of approximately 36.69 meters. Archaeological and diver surveys provide detailed structural descriptions of the submarine: it measures roughly 64 to 70 meters in length, 6 to 7 meters in beam, and stands about 5 to 6 meters high, lying in an east-west orientation with the bow facing west-southwest. The U-boat is noted for being largely intact, listing to the starboard side at an angle, with open hatches, a crushed conning tower featuring attached radar masts, and the port screw still in place. Notable structural damage includes heavy impact marks to the bow area consistent with a historical depth charge attack, creating a large hole aft of the bow on the port side, while the stern remains well preserved.
