Jackson Reef

Northernmost of the four Tiran reefs, Jackson takes the full push of water entering the strait, and its flanks show the reward: gorgonian fans, dense soft coral, and reef fish stacked into the current lines. The salvage-cut remains of the freighter Lara, wrecked in 1981, still mark the reef crest as a landmark. Most dives drift the southern and eastern faces in moderate flow, but when conditions allow, boats drop experienced groups off the northern point to hang in open blue - in summer, scalloped hammerheads patrol that deep edge. Eagle rays, turtles, and grey reef sharks round out a site that rarely repeats itself two days running.

その瞬間のために: Summer hammerhead drops off the north point; gorgonian-covered walls; the Lara's remains on the crest.

地形: Steep coral walls and terraces around a reef crown topped by wreckage

流れ（カレント）: The strait's exchange flow accelerates around the reef; slack windows are short.

エントリー: Sheltered moorings on the southern side; drift dives and blue-water drops on the exposed faces when conditions allow.

危険生物・リスク: Strong, shifting current; blue-water descents on the north side; boat traffic in the strait.

許可証＆ルール: Tiran marine-park fee applies.

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）。
