Chrisoula K, also called the MV Marcus, and also known as The Tile Wreck, is the shipwreck of a Greek freighter that sank in 1981 after crashing into the reef on the north-eastern side of Abu Nuhas. The nickname comes from the fact that the ship was carrying a cargo of over 3,000 tonnes of Italian floor tiles.
The ship was quite large, measuring 98 meters/321 feet in length and 15 meters/49 feet in width. The bow remains in good condition.
The average depth at the site is 20 meters/66 feet and visibility is good. Some current may be present.
