They call her the Titanic of the Caribbean without much exaggeration: a 180-meter Italian cruise liner that caught fire at anchor in 1961, burned for days, and sank under tow off Grand Anse. Six decades of seawater have collapsed portions of her superstructure, but the scale still stuns, and the swimming pool on the tilting deck remains one of diving's stranger sights. This is a serious dive, with the deck around thirty-five meters, frequent current, and short bottom times, patrolled by eagle rays, barracuda, and reef sharks that suit her gravity. The fire's human cost is part of her story; dive her with that respect.

その瞬間のために: Cruise liner scale, the famous pool deck, eagle rays in the blue

地形: Sand plain off Grand Anse at 50 meters

流れ（カレント）: Open-water site where current often runs; descents follow a line and dives may become drifts on ascent.

危険生物・リスク: Depth, current, and deteriorating structure; no penetration without technical training, and gas plans must be conservative.

保全: Treat the wreck as a memorial as well as a dive; take nothing from her.

ナイトロックス: ここでは価値があります。エンリッチドエア（ナイトロックス）が無減圧潜水時間を有意に延ばせる範囲にあるスポットです（利用にはトレーニングが必要です）。
