SS Nebo

The Nebo sank in 1884 on her maiden voyage from Britain, laden with railway bridge materials for Natal, and settled hull-up on the sand north of the shoal; her crew reached safety. As Aliwal's Victorian wreck she reads differently from the Produce: a single long steel mound, plates furred in growth, with her cargo-era ironwork still traceable beneath. The overturned hull forms sheltered caverns where soldierfish and big morays gather, rays rest along the scour, and the steel surfaces have become one of the coast's best nudibranch hunting grounds. History, atmosphere, and macro rather than adrenaline.

您此行的高光时刻: An 1884 steamer resting upside down; superb nudibranch searching over the plates

地形地貌: Steamer lying upturned on sand, hull largely whole, machinery exposed at the edges

水流: Same launch-and-line routine as the Produce; the two wrecks are often paired on one charter.

危险因素: Depth, swell-driven surge over the hull, and entanglement points along the wreckage.

许可证与规定: Aliwal Shoal MPA permit required, arranged via operators.

保育: A 19th-century heritage wreck inside the MPA: nothing gets lifted, moved, or entered.

高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
