Aida

The more diveable of Big Brother's two wrecks: a coral-blanketed 1950s Egyptian lighthouse tender lying down the reef wall, intact and fish-thick.

The dive

The Aida still looks like a ship. Where the Numidia is so broken and so deep that it reads as part of the reef [see numidia-wreck], the Aida keeps a recognisable shape, with an intact superstructure and davits still lining the railings. You make a negative entry and descend through the current onto the upper hull, then work the structure before riding the drift back along the reef in the shallows. She lies on her port side at a steep angle down the wall, so the whole dive is a slow track along a tilted ship.

Coming down, you meet the coral-smothered upper hull first, then at around 33 metres the point where she broke apart, the damaged central section and an engine room you can swim through where the hull is split. The quarterdeck planking rotted away long ago, leaving the steel skeleton; heavy winches sit forward of the cargo hatches; the helm and, deepest of all, the propeller lie far down toward 65 metres, past recreational range. The real draw is the encrustation and the fish. Soft and hard coral cover the whole structure, best read under a torch, and the schools are dense enough that batfish, grouper and glassfish block the light in sections. Napoleon wrasse and morays work the recesses. Most divers keep to the 25 to 40 metre band; the stern and propeller are a technical choice, not a casual one.

What makes it special

The Aida is the Brothers wreck for divers who want a wreck dive, not a technical objective. It is the diveable one. The Numidia's interest lies mostly below 40 metres; the Aida's main body sits in the recreational-to-light-tech band, roughly 25 to 40 metres on the upper and mid wreck, so an advanced diver can swim the superstructure, look into the engine room and holds, and still surface with sensible margins. It is the more intact and more photogenic of the pair, a coral-blanketed hull with swirling, light-blocking fish life set against the blue.

It also carries a genuine, well-documented backstory that the pure reef sites lack: a French-built Egyptian lighthouse tender lost while relieving the very garrison whose lighthouse still stands above the dive [see big-brother]. The history gives the dive a narrative, and the intact structure gives it the photographs. Together they make the Aida the wreck most divers actually enjoy at length out here, rather than tick off on a deep clock.

History and origin

The Aida has an unusually well-documented past for a Red Sea wreck. She was built in Nantes in the 1910s as a combined cargo and passenger lighthouse tender for Egypt's Ports and Lighthouses Administration, and she spent three decades supplying the Red Sea's lights. During the Second World War she survived an air attack that the Rosalie Moller did not, changing course at the last second so the attacking aircraft clipped her mast and crashed. After the war she joined the Egyptian Navy.

Her end came on a stormy night while she was relieving the garrison on Big Brother. Driven onto the reef as she tried to dock, she sank. Everyone aboard was saved, a Norwegian tug taking off most of the crew and the rest reaching the island. One piece of dive-boat lore is worth correcting: the Aida is sometimes called an Italian ship, almost certainly because she was carrying military personnel when she was lost. She was, in fact, an Egyptian vessel, French-built, in the service of the lighthouses she spent her life tending.

Know before you go

Bring a torch, even in clear water. The Aida's whole appeal is the coral that has blanketed her, and it only shows its colour under a light. Treat this as a deep dive on a tilted hull, not a leisurely potter: the structure keeps dropping away below you, and it is easy to slide past your planned depth without noticing. Her stern and propeller sit in technical ground, best left alone unless you came equipped for them.

The broken-open engine room is a swim-through with light overhead, not a deep penetration, but treat any time inside the hull with respect for your training. Watch for downcurrents on the wall and the easy creep of depth on a hull that keeps tilting away below you. A surface marker is standard kit for the drift pickup, and nitrox makes sense given how often the dives run deep. The experience expectation here is genuine. These islands are reached only by liveaboard, and they assume advanced, current-comfortable divers, not a first deep wreck.

Why Dive Aida

What makes this dive site stand out.

  1. 1
    Intact, recognisable hull

    Superstructure, engine room, davits and helm all read as a ship, unlike the broken Numidia.

  2. 2
    Recreational wreck band

    The main body sits around 25 to 40 m, swimmable by advanced divers within no-deco margins.

  3. 3
    Light-blocking fish schools

    Batfish, grouper and glassfish pack the hull thick enough to dim the light in places.

  4. 4
    Coral-blanketed structure

    Soft and hard coral cover the whole wreck, the colour best read under a torch.

  5. 5
    Documented backstory

    A French-built Egyptian lighthouse tender lost relieving the garrison whose light still stands above.

Frequently Asked Questions

Is the Aida wreck Italian or Egyptian?
Egyptian. She was built in France for Egypt's Ports and Lighthouses Administration and later served the Egyptian Navy. The Italian label comes up on dive boats and in old forum posts, almost certainly because she was carrying military personnel when she was lost, but the documented history is Egyptian.
How deep is the Aida wreck?
She lies down a wall on her port side. Engine remnants sit on the reef top near 7 metres, the bow around 25, the hull break and engine room near 33 to 35, and the propeller deepest at about 65 metres. The recreational dive works the 25 to 40 metre band; the stern is technical.
Aida or Numidia, which wreck is better?
It depends on what you want. The Aida is shallower, more intact and easier to enjoy at recreational depth, with dense fish life and a recognisable ship. The Numidia is deeper, more broken and more dramatic, spanning recreational to technical depth. Most divers do both on a Brothers stop and contrast the shallow with the deep.
Can you penetrate the Aida wreck?
Only lightly. Where the hull broke apart, the engine room is open as a swim-through with daylight overhead rather than a true penetration. Going deeper inside the structure is a technical decision that needs proper training, and the stern and propeller toward 65 metres are technical depth regardless.
What sank the Aida and was anyone killed?
A storm. She was driven onto Big Brother's reef in 1957 while trying to dock and relieve the lighthouse garrison. Everyone aboard survived, with a Norwegian tug taking off most of the crew and the rest reaching the island. No lives were lost.
