Big Brothers Island is roughly oblong with a NW - SE attitude. The Numidia is found off the northern-most tip of the island. Quite often, however, there is a strong current running straight onto the wreck.
This is a dive to set the heart racing and one of the most incredible shipwrecks available to Divers. Like the Aïda, she also defies all the known laws of gravity and lies "up" the reef at an almost vertical angle. After nearly 100 years underwater she is, of course, now an integral part of the reef itself and will never move.At a depth of only 8m the Diver will find the Bows are well broken and marked by a pair of Railway Engine Wheels originally carried as deck cargo. From here, the ship quickly takes on its original shape and the Diver is soon descending to deck level.

The first thing that most Divers comment on, however, is the absolute colour that now adorns this vessel. Hard Corals and Soft Corals have colonised this ship in a manner similar to the Aïda - making them amongst the most beautiful shipwrecks in the world. The railings, masts, lifeboat davits, windlasses and deck winches are all still in place - having become part of a living Reef of such vibrancy that it is easy to lose sight of the fact that this is a "wreck dive!"
In amongst the varied colours - from the lightest greens to the deepest reds, is a fish life that has made this shipwreck "home." The groupers are probably the most outstanding inhabitants - but all Divers have their own favourites and each is found right here. As for the ship itself, she is able to provide every type of Dive for every type of Diver. Even those who abhor wrecks will like this one.
The wooden decking has, of course, gone and, of course, the cargo was salvaged. This, however, provides an incredible opportunity to investigate a large ship at whatever depth suits the personal requirement. Forward of the central bridge are two cavernous cargo holds with ventilation hatches along the starboard side. The decks are now a square pattern of steel in between which is the lower half of the forward mast
Immediately behind No 2 Hold is the raised central "castle" with its accommodation and what remains of the Bridge. Having been constructed of wood on a steel floor, all but the basic outer framework has rotted away. We are now at a depth of 50m and the remainder of the ship lies in very deep water.
Immediately behind the bridge is the ship’s funnel which has fallen over to one side. Here several lifeboat davits are swung out. The Engine Room is immediately below. Further aft are Nos 3 and 4 Holds - and the decking is very similar in appearance to that nearer the Bows. Once again, the Diver will find the lower half of an equally stout rear mast - also defying gravity, along with all the attendant deck winches.
The stern is raised and provides a beautifully rounded poop deck below which the single large propeller is found at a depth of some 80m.
Apart from the damage encountered at the Bows, all metal structures are fully intact throughout the ship and they are all covered in the most exciting arrangements of Hard and Soft corals - which only begin to fade in their intensity from 50m downwards. The largest Grouper are also a feature of these deeper aspects of the wreck.
