Wreck Diving – Produce & Nebo
Aliwal Shoal is home to two of South Africa’s most iconic wreck dives — the Produce, a Norwegian cargo ship sunk in 1974, and the older Nebo, a 19th-century wooden screw steamer. Both wrecks offer excellent marine life, strong photographic opportunities, and unique underwater architecture that complements Aliwal’s reef diving perfectly.
The Produce Wreck
Depth: 26–32m

- Excellent for wreck penetration (qualified divers)
- Frequent Blacktips and pelagic visitors
- Stunning wide-angle photography
The Nebo Wreck
Depth: 26–30m
Dive Level: Advanced Open Water+
The Nebo, wrecked in 1884, is partially collapsed with scattered hull sections, rib structures, and large beams covered in marine growth. It attracts macro life, rays, turtles, and during peak seasons, passing sharks.
- Historic structure with dramatic wreckage
- Excellent macro photography & nudibranchs
- Shark sightings during baitfish activity

- Great for slow-paced, relaxed exploration
- Macro species: nudibranchs, shrimps, small morays
- Excellent visibility in winter & early morning

Launch & Boat Procedures (Surf Launch)
Aliwal Shoal uses a surf launch, one of the most exciting and memorable parts of diving in South Africa. Launching from Umkomaas requires teamwork, trust in the skipper, and a clear understanding of boat procedures. Below is everything divers need to know before heading out.
Before the Launch
