Chrisoula K

Also known as: Anna B, Dora Oldendorff, Krisoula K, Tegelwrak, Tile Wreck

Greek cargo freighter sunk in 1981 at Abu Nuhas reef, with Italian floor tiles still visible in the cargo holds, diveable from 3-28m.

The dive

Tiles. Thousands of them, stacked in the cargo holds like a warehouse floor that never arrived in Jeddah. The Chrisoula K sits almost upright on Abu Nuhas reef, her bow jammed into the coral at 3 metres and her stern angling down to sand at 28m. Most divers start deep at the propeller and rudder, both still in place after four decades, then swim forward along the hull past the engine room and bridge deck. The cargo holds are the centrepiece: open swim-throughs where sunlight catches the tile stacks and glassfish swirl around your torch beam. Lionfish hang motionless in every shadow. The bow section barely registers as a ship anymore. Coral has claimed it so thoroughly that reef and wreck blend into one structure, and this is where you do your safety stop.

What makes it special

Cargo tells you everything about this wreck before you even descend. The Chrisoula K is the Tile Wreck: hold after hold of Italian floor tiles, some with "Made in Italy" still readable on the surface after more than 40 years underwater. No other wreck in the Red Sea carries anything like it. But the tiles are only half the story. This wreck spans a full range from snorkelling depth at the bow to 28m at the stern, and that range creates two different dives on the same hull. The shallow sections host dense coral growth and reef fish; the deeper stern harbours the engine room, recorded as fitted with a 9-cylinder MAN diesel, accessible to experienced wreck divers through narrow passages. The workshop still contains a drill press, a lathe, and a galley oven. Forty years underwater and the tools are recognisable.

History and origin

The Chrisoula K began as the Dora Oldendorff, a 3,720 GRT cargo ship built in 1953-54; the shipyard is disputed between two accounts (see FAQ). She sailed as the Anna B from 1970, then as the Chrisoula K from 1979 under Clarion Marine of Piraeus. On 31 August 1981, carrying a full cargo of Italian floor tiles bound for Jeddah, she struck the northeast corner of Abu Nuhas reef at full speed. Her bow drove into the coral and stood clear of the water before she sank by the stern, and she was declared a total loss. All 21 crew were taken off by the Egyptian Navy and landed at Suez; no one was lost. A few divers have raised the idea that this hull might actually be a different wreck, the Marcus, with the true Chrisoula K lying deeper below.1

Know before you go

Two dives are the minimum to cover both the deep stern route and the mid-ship holds. The cargo hold swim-throughs are straightforward with clear exits. The engine room is a different matter. Restricted passages, structural obstructions, and significant silt-up potential make it suitable only for divers with wreck training. Bring multiple torches. Abu Nuhas sits in the open Strait of Gubal, so surface conditions can be rough even when the dive itself is calm below. Day boats from Hurghada take 2 to 2.5 hours each way. A liveaboard gives you time for multiple wrecks and avoids the long daily transit. Nitrox is worth having for the stern section at 26-28m.

ModerateMin cert: Open WaterNitrox recommended

OW divers can explore the exterior and cargo holds (3-15m). AOW required for the full wreck to stern depth. Wreck specialty required for engine room penetration.

Summary

Exterior and holds are easy. Engine room is advanced with restricted passages and silt-out risk.

Safety considerations

  • Overhead: Fallen beams, poles, and structural debris inside wreckFollow briefed penetration routes and avoid touching or grabbing wreck structure
  • Overhead: Engine room is a confined overhead environment with narrow entries and silt-out riskOnly enter with wreck specialty training and a guide. Carry multiple torches.
  • Current: Medium to strong currents possible at Abu NuhasDeploy SMB for ascent and dive to your guide's plan for the day's conditions
  • Depth: Stern at 26-28m exceeds OW limitsOW divers should stay in the 3-15m range

Frequently Asked Questions

Why is the Chrisoula K called the Tile Wreck?▾

The ship was carrying a full cargo of Italian floor tiles from Italy to Jeddah when it sank in 1981. Over four decades later, stacks of tiles remain packed in the cargo holds, some with 'Made in Italy' inscriptions still legible. This distinctive cargo earned the wreck its universal nickname among Red Sea divers.

Can beginners dive the Chrisoula K?▾

Open Water divers can explore the wreck exterior and the cargo holds between 3 and 15m. The holds offer straightforward swim-throughs with clear exits on both sides. The bow at 3m is even accessible to snorkellers. However, the stern at 26-28m requires AOW certification, and the engine room demands wreck specialty training due to confined passages and silt-out risk.

How should I plan my dive on the Chrisoula K?▾

Two dives work best. First dive: start at the propeller and stern (26-28m), swim forward past the engine room and bridge, finish at the holds with a safety stop on the coral-encrusted bow. Second dive: focus on the cargo holds, workshop, and superstructure at shallower depths. This splits the deep and shallow highlights across two comfortable profiles.

Where was the Chrisoula K built?▾

Where she was built is disputed: one account places the shipyard in Lübeck, Germany, with a launch in December 1953; another places it in Landskrona, Sweden, built in 1954. Both agree she was first named Dora Oldendorff. The record does not settle which shipyard is right.

Could this wreck actually be the Marcus, not the Chrisoula K?▾

A few divers have floated that idea, suggesting the real Chrisoula K lies deeper below. It surfaces in only one account and isn't repeated elsewhere; the wreck is dived and documented as the Chrisoula K.

Is the wreck in good condition?▾

The stern and engine room remain largely intact. The shallow bow has deteriorated more from wave action, and in places the reef and wreck merge completely. The stern is reported to be slowly separating from the main hull. Penetration remains excellent in the holds and engine room, though conditions change over the years as structural sections shift.

What camera setup works best on the Chrisoula K?▾

Photography conditions are strong throughout the wreck. Natural light works well in the shallow holds where sunlight filters through the hull structure. Wide-angle captures the full wreck on good visibility days. Macro setups excel inside, where nudibranchs, shrimp, gobies, and lionfish hide in the wreck crevices. Two dives with different lens setups is the recommended approach.
