S.S. Thistlegorm

Two hundred tonnes of WWII military cargo sit in the holds of a 130-metre ship on white sand at 30 metres. Most trips split the wreck across two dives. The exterior route begins at the stern, where the anti-aircraft gun still points skyward at 18m. From there, divers move along the hull past the gap where the explosion tore the ship apart and the two steam locomotives rest on the seabed at 30m. The scale of the engines only registers when another diver swims alongside for reference. At the bow, a WWI-era 4-inch cannon completes the circuit.

The second dive enters the forward cargo holds. Hold 1 and 2 contain the motorcycles and trucks, recognisable after 80+ years despite coral colonisation. Norton 16H and BSA machines sit on their frames. Deeper in, Lee-Enfield rifles stand in rows and ammunition cases remain stacked. Torch beams pick out serial numbers and tyre treads. Silt is the enemy inside: one careless fin stroke can blank the hold for everyone behind you.

The Thistlegorm's reputation rests on a combination no other recreational wreck matches. The cargo is not crates or scrap. It is an identifiable WWII military supply chain frozen mid-transit: motorcycles, trucks, armoured vehicles, rifles, aircraft wings, Wellington boots, and two steam locomotives. The depth range (16-32m) keeps the entire wreck within AOW territory. And Cousteau's 1955 discovery adds a layer of diving heritage few wrecks carry.

The tension between the wreck's significance and its popularity runs through every diver account. Some find it transcendent regardless of crowds. Others note decades of damage from mooring lines and looting. Both are honest. The wreck is diminished and still magnificent.

The difference between a good Thistlegorm dive and a great one is timing. Day boats from Sharm leave at 5am and arrive mid-morning together. By then, 20+ boats are moored and the holds fill with divers and silt. Liveaboard guests dive at dawn or after dark, when the wreck belongs to them. Night dives are liveaboard-exclusive and widely rated as the most atmospheric way to experience the wreck.

Nitrox is close to essential: at 30-32m, air cuts bottom time sharply and multiple dives per day load nitrogen fast. A torch is mandatory for hold penetration. Deploy an SMB before ascending into the surface traffic above. Currents can strengthen with the lunar cycle, so descend and ascend on the mooring line when conditions are uncertain.
