Zabargad Wreck

A steel mast breaks the surface at low tide, and most dives drop straight down the mooring line beside it into the calm bay. The ship resolves within the first few metres: a seventy-three-metre hull resting upright on the sand at 24 metres, its bow snapped off and lying apart to one side. Divers usually circle the outside first, along a deck softened by hard and soft coral, past big winches and anchor chains at the bow and davits amidships, while glassfish pour off the superstructure.

The interior is the reward for those trained for it. The pilothouse still holds the remains of the helm and chart room, and the engine room and holds open up below, where the ship's listening gear once sat. A torch brings the spaces to life even in clear water. Penetration is a true overhead far from help, so the inside is for wreck-trained divers with a light and a plan, not a casual swim-through.

Nothing else in the Deep South looks like this. The rest of the marine park is shark walls and coral gardens; here, in a sheltered bay, a complete Cold War wreck rests within easy recreational depth. After days of hard drift dives off the neighbouring islands, this is the safari's exhale: flat water, a long slow lap of the hull, and a strange relic to explore. The wreck pulls its own visitors, divers who make the crossing for the mystery as much as for the marine park.

The ship is half-identified and half-riddle. Its hull markings place it as a Soviet survey vessel rigged for signals and electronic intelligence, a Cold War spy ship in plain terms. The popular name, the Khanka, has never been confirmed: the vessel of that name in the records does not match this class of ship, and no matching one has ever been traced. It is thought to have struck the reef and gone down before the mid-1980s, though no official record of the loss survives. Tales of Cyrillic writing inside and a precise sinking date belong to dive-boat lore. What is certain is the hull, upright and coral-grown, with the question of its name still open.

Treat the interior as a real overhead dive or leave it alone. The pilothouse, engine room and holds are open, but they are enclosed steel far from help, so the inside is for divers with wreck training, a torch and a clear plan. Bring a light even in good water, and use the mast as your ascent and safety-stop marker. Night diving is off the table at the marine-park islands, and the nearest hyperbaric chamber is hours away, so keep the profile conservative and hold gas in reserve. Like the rest of the pair, the wreck is reached only by liveaboard, with the marine-park rules, fees and experience gate handled at the trip level.
