U-352

On 9 May 1942 the Coast Guard cutter Icarus depth-charged U-352 to the bottom off Morehead City; accounts put her dead at 13 to 15, and the 33 survivors became some of the first German prisoners taken by US forces in the war. The submarine lies listing on clean sand at around 35 m, conning tower recognizable, pressure hull exposed where the outer plating has gone - an unmistakable silhouette that no artificial reef can imitate. She is a war grave in practice and dived as one: look, photograph, take nothing, enter nothing. Amberjack spiral the tower, sand tigers drift past in summer, and the blue Gulf Stream water completes a dive of real historical weight.

Il momento che aspettavi: An authentic U-boat casualty of the Battle of the Atlantic, often in blue 25 m visibility

Topografia: Type VIIC U-boat listing to starboard on sand, hull largely intact

Corrente: Gulf Stream influence brings blue water and flow in varying doses; descend the anchor line.

Pericoli: Depth with short no-deco times, current, occasional low-vis days inshore of the Stream.

Conservazione: Treat as a war grave: no penetration, no artifact removal - the site has lost too much to takers already.

Nitrox: Vale la pena qui — i profili rientrano nella fascia in cui l'aria arricchita (nitrox) prolunga in modo significativo il tempo senza decompressione (con la formazione necessaria per utilizzarla).
