Giannis D

The Giannis D went onto Abu Nuhas in April 1983 carrying sawn timber, and her midships collapsed as she worked against the reef, leaving bow and stern as separate wrecks joined by wreckage-strewn rubble. The stern is the star: intact, heeled hard to port, its A-frame gantry and accommodation block still legible, and its engine room open to trained divers - a famously disorienting space where the 45-degree list argues with every instinct about which way is up. Glassfish own the interior, lionfish drift along the companionways, and the propeller sits in clean sand for wide-angle work. She is the most atmospheric of the reef's four wrecks and the one that repays a second visit most.

その瞬間のために: The tilted engine room; the intact heeled stern; glassfish swirling through the accommodation.

地形: Broken hull in three sections on sand and coral rubble at the reef base

エントリー: Western end of Sha'ab Abu Nuhas; moorings on the sheltered side, with surge over the wreck in any north wind.

危険生物・リスク: Surge moves divers against steel in north winds; the listing interior disorients - penetrate only with training and a light.

保全: Artifact removal is illegal; the wreck's fittings have already thinned over four decades.

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）。
