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.

Момент, ради которого вы приехали: Dreadnought scale in the gloom, casemate guns along the hull side, the fleet's most prestigious tick

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

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

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

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

Найтрокс: Здесь это оправдано: профили находятся в диапазоне, где обогащённый воздух реально увеличивает время без декомпрессии (при наличии соответствующей подготовки).
