SMS Markgraf

Markgraf fought at Jutland and now lies almost fully inverted in the deepest water of the German fleet, her upturned hull rising from around 45 m to the mid-twenties. The scale registers slowly: a wall of riveted plate longer than a football pitch, rudders raised toward the light, and along the port side the crushed gallery where casemate guns and portholes emerge from the shadows. This is a dive of atmosphere rather than easy sightseeing (dark, deep and unforgiving of poor planning), and for many wreck divers it is the single best thing in British waters.

O momento pelo qual você vem: Dreadnought scale in the gloom, casemate guns along the hull side, the fleet's most prestigious tick

Topografia: A Konig-class battleship lying nearly upside down on a silt-and-shell seabed at about 45 m

Entrada: Shotline descent from Stromness charter boats; the deepest and most demanding of the German fleet.

Perigos: Depth, darkness, silt and inverted orientation that disorients; penetration is a technical-team undertaking only.

Conservação: A scheduled monument: nothing is removed, nothing disturbed. A century of salvage history already scars the fleet; divers should not add to it.

Nitrox: Vale a pena aqui: os perfis situam-se na gama em que o nitrox prolonga significativamente o tempo sem paragem de descompressão (com a formação para o usar).
