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.

वह पल जिसके लिए आप आते हैं: Dreadnought scale in the gloom, casemate guns along the hull side, the fleet's most prestigious tick

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

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

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

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

Nitrox: यहाँ इसका फ़ायदा है — प्रोफ़ाइल उस रेंज में हैं जहाँ enriched air no-stop समय को सार्थक रूप से बढ़ाता है (इसके उपयोग के प्रशिक्षण के साथ)।
