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.

Le moment pour lequel vous venez: An 1884 steamer resting upside down; superb nudibranch searching over the plates

Topographie: Steamer lying upturned on sand, hull largely whole, machinery exposed at the edges

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

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

Permis & règlements: Aliwal Shoal MPA permit required, arranged via operators.

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

Nitrox: Intéressant ici — les profils se situent dans la plage où le nitrox prolonge significativement le temps sans palier (avec la formation pour l'utiliser).
