HMHS Britannic Wreck

Korissia, Kea · Kea Island, Cyclades · Greece

The HMHS Britannic is one of the most significant shipwrecks in the world and arguably the ultimate technical wreck dive. Lying on her starboard side in 120 metres of water in the Kea Channel, she is the largest passenger ship on the seabed — at 269 metres, slightly larger than her famous sister, the Titanic. The Britannic was the third of the White Star Line's Olympic-class liners. Launched in Belfast in 1914, she never carried a single fare-paying passenger. World War One intervened, and she was requisitioned as a hospital ship. On 21 November 1916, while steaming through the Kea Channel to collect wounded soldiers, she struck a mine. Despite improved watertight compartments designed after Titanic's loss, she sank in 55 minutes. Thirty lives were lost, but swift evacuation saved over a thousand crew and medical staff. Descending the shot line into the deep Aegean blue, the wreck materialises from darkness at around 90 metres — first as a shadow, then resolving into the unmistakable profile of an ocean liner. The scale is almost incomprehensible. The hull stretches in both directions beyond visibility, encrusted with sponges and gorgonians swaying in gentle current. At this depth, every moment on the wreck is precious and costly in decompression time. The bow section is particularly dramatic, with forecastle and anchor chains clearly visible. Portholes stare out like empty eye sockets, many still with original glass. The warmer, less corrosive Mediterranean waters have preserved structural details long vanished from Titanic's remains in the North Atlantic. The wreck is a protected cultural heritage site requiring permits from the Greek Ministry of Culture. Only a handful of expeditions dive her each year. Diving the Britannic is a privilege reserved for those with the technical skills and preparation to reach her safely, an experience that redefines what wreck diving can be.
