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.

اللحظة التي جئت من أجلها: Dreadnought scale in the gloom, casemate guns along the hull side, the fleet's most prestigious tick

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

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

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

الحفاظ على البيئة البحرية: A scheduled monument: nothing is removed, nothing disturbed. A century of salvage history already scars the fleet — divers should not add to it.

نيتروكس: يستحق هنا — تقع البروفايلات في النطاق الذي يمدّد فيه النيتروكس وقت التوقف اللاإلزامي بشكل ملموس (بشرط امتلاك التدريب اللازم لاستخدامه).
