Giannis D

Launched in Japan in 1969 as Shoyo Maru, this mid-sized freighter passed through several owners before a Greek company renamed her Giannis D, painting the funnel with the D of the Dumarc line. In April 1983 she loaded sawn softwood at Rijeka on the Adriatic, bound for Jeddah and Hodeidah. Crossing the Strait of Gubal on 19 April, she ran at full sea speed onto the northwest corner of Sha'ab Abu Nuhas, the low reef that has collected more ships than any other in the northern Red Sea. The crew abandoned safely, and after weeks of pounding the hull broke into three. Her stern settled almost intact on its port side, engine room enclosed and inviting, while the midships collapsed into scattered plate. Within a decade she had become the signature wreck of Abu Nuhas, dived daily from Hurghada and El Gouna boats.

她是如何沉没的: Ran onto Sha'ab Abu Nuhas reef at speed, 19 April 1983.

环境条件: The stern remains remarkably whole and is corroding slowly; the bow sits separately and the middle third is flattened wreckage.

穿越式潜水: Full With Training. The tilted engine room is the famous swim: its slanted decks scramble the inner ear, so it belongs to trained wreck divers with a guide; the open midships is easy. 进入任何封闭式环境都需要专项培训：至少需要沉船潜水认证，完整穿越则需要技术级沉船培训。

建议持有证书: Advanced Open Water

水流: Mild · 能见度: 10–25 m

海洋生物: Glassfish pack the engine room, anthias shimmer over the masts and A-frame, and lionfish, groupers, and batfish work the broken midships.

危险因素: Disorienting angles inside the hull; surge over the shallow reef top; occasional swell makes boarding boats lively.

Leave fittings where they lie; Egyptian authorities prohibit removal.
