SMS Kronprinz Wilhelm

The Kronprinz fought at Jutland in 1916, took her place in the North Sea standoffs that followed, and was renamed Kronprinz Wilhelm in 1918 to honor the crown prince — just in time to surrender. Interned at Scapa Flow with the rest of the High Seas Fleet while the Versailles negotiations dragged on, she was one of the 52 ships that went down on 21 June 1919 when Admiral Ludwig von Reuter, believing the armistice was expiring and determined to keep his fleet out of British hands, signaled the order to scuttle. The salvage empire of Ernest Cox lifted most of the fleet for scrap in the 1920s and 30s; the Kronprinz Wilhelm was among the seven warships too deep or too awkward to raise, and so became one of diving's great time capsules. She lies almost fully capsized in about 38 meters, her vast hull the first thing divers meet, with 12-inch gun turrets hanging beneath at the seabed and casemate guns, rudders and torpedo tubes readable along the wreck. Of the three surviving battleships she is often rated the most navigable introduction.

沈没の経緯: Scuttled with the interned German High Seas Fleet on Admiral von Reuter's order, 21 June 1919.

コンディション: Coherent capsized hull a century on; internal collapse advancing, with salvage scars from early blasting

洞窟貫通（ペネトレーション）: Limited. Openings beneath the upturned hull lead into dark, silt-laden, collapsing spaces — technical wreck teams only, and even they treat her cautiously. オーバーヘッド環境への進入には専門的なトレーニングが必要です——最低限、レック・ダイビング認定資格が必要で、完全貫通には技術的なレック・トレーニングが求められます。

推奨ライセンス: Advanced Open Water with deep and drysuit experience

流れ（カレント）: Mild · 透明度: 4–12 m

海洋生物: Plumose anemones and dead-man's-fingers coat the shaded steel, ballan wrasse and saithe patrol the hull, lobsters and edible crabs den in the plating, and dense brittlestars carpet the seabed.

危険生物・リスク: Cold dark water, depth, disorienting inverted topography, and entanglement in old salvage debris
