The Chrisoula K struck Abu Nahas reef in August 1981 carrying a cargo of Italian floor tiles, and those tiles, still stacked in the holds decades later, gave her the name divers use: the tile wreck. She drove hard into the reef, which crushed the bow, while the rest of the hull settled back along the slope.

The stern and engine room are the heart of the dive, intact and reaching down to around 27m. The holds are open and stacked with their cargo, an unusually clear reminder of what these ships were doing when they came to grief, and the engine room is large enough to draw trained wreck divers. The upper structure sits shallow enough to give a long, relaxed dive with plenty of no-decompression time.

The identity of the wreck was confused for years with the nearby Marcus, and you will still hear the names traded. What matters underwater is straightforward: the bow is broken into the reef, the stern is the prize, and penetration of the engine room and holds is for trained divers with a guide.
