MV Produce

The Produce, a Norwegian bulk carrier, struck the northern edge of Aliwal Shoal in 1974 and went down with no loss of life — the crew was famously rescued with help from local fishermen. Fifty years of Indian Ocean later, she lies broken and softened on the sand, her holds and hull plates a giant fish shelter. Brindle bass the size of small sofas loiter in the shadows, oversized morays share cracks with lobster, and clouds of geelbek and baitfish wash over the wreckage. The site's mood depends entirely on the day's water: emerald and moody or blue and generous.

その瞬間のために: Resident giant grouper (brindle bass); fish-packed broken holds

地形: Large broken freighter lying on sand inshore of the shoal proper

流れ（カレント）: Open-water descent down a line; current and visibility swing with the Agulhas edge.

危険生物・リスク: Depth, loose plates and snag points, and variable visibility.

許可証＆ルール: Aliwal Shoal MPA permit required, arranged via operators.

保全: The wreck is protected within the MPA — no artifact recovery, no penetration of unstable sections.

ナイトロックス: ここでは効果的です——このエリアのプロファイルは、ナイトロックスが無減圧潜水時間を有意に延ばせる水深帯にあります（適切なトレーニングを受けていることが前提です）。
