Giannis D

Also known as: Ghiannis D, Markos, Shoyo Maru, Wood Wreck, Yannis D, Yiannis D

Japanese-built cargo ship lost on Abu Nuhas reef in 1983, lying on her port side with a mast near the surface and a bridge and engine room divers enter.

Last updated October 2026

The dive

The buoy line drops onto a wreck that can be seen from the surface, her superstructure canted over to port. The mast is the first thing within reach, almost parallel to the reef and topping out at 4-5 metres, so the shallowest part of the ship is also the way the dive ends. Most divers head aft first for the propeller, which means leaving the shallow part of the wreck: the stern lies on sand at anywhere from 20 to 30 m depending on the account, past the depth Open Water training covers, so stay at or above your certified depth. Some divers enter through an aft opening. The route then works round the wreck to the amidships and forward sections and finishes at the bridge or along the reef slope above.

At the stern the bridge and funnel stack up in tiers, with the big D still readable on the funnel. The bridge section opens into the crew quarters, engine room and mess hall; the engine room, at about 13 metres and full of glassfish, is reached through that interior, so it belongs to wreck-trained divers or a guide. Because the ship lies on her port side at a list that dive guides put near 45 degrees, floors become walls and doorways open sideways. Batfish and lionfish work the soft-coral-covered hull, and moray eels, bannerfish and jackfish sit on the reef slope near the bridge.

What makes it special

Lying on her port side, the ship shows every deck at an angle: the funnel with its D, the canted bridge and the glassfish-filled engine room all sit at a tilt, and one account reports divers voting her the most photogenic vessel in the Red Sea.

Her cargo of sawn softwood from Rijeka earned her the nickname Wood Wreck, and the earlier name Markos is still discernible on the hull.

History and origin

She was launched in 1969 as the Shoyo Maru at a Japanese yard in Imabari and sold on as the Markos in 1975. In 1980 the Dumarc Shipping and Trading Corporation of Piraeus bought her and renamed her Giannis D, which makes her Japanese-built and Greek-owned. In April 1983 she was loaded with sawn softwood at Rijeka, Croatia, bound for Jeddah in Saudi Arabia and Hodeidah in Yemen, and drove hard onto the north-west corner of Sha'ab Abu Nuhas. The crew abandoned ship and were rescued, with no loss of life. She split as she sank1; in Dutch the nickname is Houtwrak.

Know before you go

Boats run out from Hurghada, about 25 miles by one account, and transit is reported at up to about two hours. Most dives launch from RIBs, because larger boats moor further off.

Navigation inside the wreck is disorienting because of the list, and only experienced wreck divers, or divers with a qualified guide, should attempt penetration. In rough weather strong currents run through the wreck, and the surface is exposed: very large waves are reported on the ascent, so plan the way back up before you drop.

Why Dive Giannis D

What makes this dive site stand out.

  1. Funnel with a large D

    Bridge and funnel rise in tiers at the stern, the D still legible on the funnel

  2. Mast near the surface

    The mast reaches 4-5 m and runs almost parallel to the reef, a fixed line for the safety stop

  3. Wreck on her port side

    The list turns the interior sideways and makes orientation difficult

  4. Glassfish in the engine room

    Clouds of glassfish fill the engine room at about 13 m

  5. Wood Wreck cargo

    Sawn softwood from Rijeka earned her the nickname

Warmer water and weather in summer; dived all year, with February usually the coolest water.

ModerateMin cert: Open Water

The mast, bridge and upper hull sit well inside Open Water depth in good weather. The stern lies deeper than 18 m in every account, and entering the wreck is for experienced wreck divers or divers with a qualified guide. A Dutch dive directory advises advanced divers when the weather is bad.

Summary

Moderate and weather dependent: the list disorients inside the wreck, and rough weather brings strong current in the wreck and large waves on the ascent.

Safety considerations

What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.

  • Orientation: The wreck's list makes navigation inside disorientingKeep the exit in view and stay within your wreck training
  • Overhead: The bridge section opens into the crew quarters, engine room and mess hall; penetration is for experienced wreck divers or divers with a qualified guideEnter only with wreck training or a guide, and keep the way out in sight
  • Current: Strong currents inside the wreck in rough weather, and very large waves on the ascentStay at or above your certified depth and ascend in a controlled way

Frequently Asked Questions

Was the Giannis D lost on 19 April or 13 April 1983?▾

Two accounts give 19 April and one gives 13 April; all agree on April 1983, when she ran onto the reef at full speed. The date changes nothing about the dive.

Does the Giannis D lie in two pieces or three?▾

Some accounts describe two halves and others three sections. In both readings the stern and the bow are the two large masses.

The mast tops out at 4-5 m but the stern is reported at 20 to 30 m: how much of the wreck does an Open Water diver get?▾

The mast, the bridge at about 6 m and the upper hull are well inside Open Water depth in good weather, and the mast is the shallow end of the dive. Every account puts the stern past the 18 m that Open Water training covers, so stay at or above your certified depth. The engine room at about 13 m is shallow enough, but going inside is for divers with wreck experience or a qualified guide.

Is the Markos a second wreck beside the Giannis D?▾

Markos was this ship's own name from 1975 to 1980, and it is still discernible on the hull, which is why divers sometimes talk about a Markos or a Markos D. One account says rumours of a separate wreck of that name circulate although no such vessel exists.
