Ann Ann Wreck

The biggest wreck dive off Jeddah. She sank in 1977 with her bow driven into the reef and has been broken up by heavy seas since. She sits upright facing east, from 5 m at the bow down to 32 m at the stern.

The guided dive lasts about 7 minutes. It goes deep first, then works back up to the bow. Tap Sound for regulator breathing. Take control any time with the joystick or by dragging to look.

Dossier

Everything in this list comes from published dive-site descriptions. It sets the model's depths, attitude and details.

Name: Known to divers as the Ann Ann. No public source gives her original name, type, tonnage or builder.
Location: Abu Faramish reef, also called 26-Mile Reef, about 2 hours by boat from Jeddah, Saudi Arabia
Size: Described as the largest wreck dive in Jeddah
Loss: Sank in 1977. Her cargo was removed during attempts to refloat her, so the holds are empty.
Attitude: Upright, facing east, with the bow ploughed into the reef
Depths: Bow at about 5 m. Stern figures vary between sources: 27 m, about 30 m and 32 m.
Condition: Badly broken up. Because she is shallow, heavy seas have battered her since 1977, and sections shift 3–5 ft (about 1–1.5 m) in heavy swell.
Features: The galley, the electrical room and the captain's quarters can be entered. The huge rudder is covered in shellfish, and the massive propeller in soft coral. A lone toilet sits upright on the wreck, and divers pose on it.
Life: Blue-striped snappers, blue-spotted stingrays, dogtooth tuna, occasional whitetip reef sharks, barracuda, goatfish, broom-tailed filefish, coral groupers, Sohal surgeonfish, dolphinfish and humphead wrasse
Divers: Intermediate to advanced. High swell over the wreck and strong currents are reported. Visibility is around 18 m. Penetration only with training and an instructor.
Unconfirmed: One dive-site listing, marked by that site as unverified, says the wreck fell onto its side in a storm in 2022 and gives depths of 14–26 m. No other source repeats this, so the model shows her upright. Please check with a Jeddah dive centre.

No plans, survey, sonar scan or photogrammetry of this wreck have been published, and her original identity is unknown. The ship is a reconstruction of a typical 1960s–70s engines-aft general cargo ship, fitted to the documented depths and details. Check it against your own footage.

Assumed

Hull: 86 m long, 13.2 m beam, 7.4 m depth, with a raked stem, a cruiser stern over an open propeller aperture, a forecastle, and a raised poop carrying the superstructure.
Attitude: upright, bow ploughed into the reef, trimmed about 10° down by the stern with a slight list to port. That puts the bow at 5 m, the stern deck at about 21 m, the propeller at about 30 m, and the sternframe on the sand at 32 m. The different stern depths quoted by sources fit different points on the stern.
Layout: three holds, a pair of kingposts, a mast and aft kingposts with derricks. The superstructure has the galley, mess and washroom on the first level, the captain's cabin forward on the second, and the wheelhouse on top.
Damage: plating torn open at four places, the deck sagging amidships, the mast and one kingpost down, and the wheelhouse torn off and lying on the sand to starboard. The walls around the toilet are gone, which is why it stands alone.
The electrical room is placed inside the poop behind the port door, and the galley and captain's cabin are opened by holes in the starboard side. Their real positions are not recorded.
Reef walls on both sides and a reef top at about 2 m ahead of the bow. The layout is illustrative.

Dive mode

The guided dive goes to the deepest point first and works back up, as a real multilevel dive should.
Near the bow, the swell pushes you back and forth on a 9-second cycle. The surge fades out by about 15 m.
The dive computer's no-decompression limit uses the recreational air table and a simple nitrogen-loading estimate. Gas use assumes a 12 L tank and 15 L/min surface consumption. It is for immersion only. Never plan a real dive with it.
Breathing cycles every 5 seconds. Exhaled bubbles rise and grow as they rise, as they do in real water. Regulator sound is synthesised in your browser.

How it's rendered

Water absorbs red light fastest, then green, then blue. The shader applies that per channel along both the sunlight's path down and your line of sight. The bow keeps its colour at 5 m, and the reds are gone by the propeller. Switch on the torch to bring the colour back up close.
Moving caustics, light shafts, marine snow, ambient occlusion and bloom. Growth, rust, rivets and sand ripples are generated per pixel from position, so detail holds up close. Turn off Cinematic on slower devices.

What would sharpen it

The ship's original name, so her Lloyd's Register entry (type, tonnage, builder, year) can fix the hull form.
A lap of the hull on video at a steady 2–3 m standoff, plus a few measured distances. That is enough for photogrammetry.
Depths at the bow, stern deck, propeller and sand, and a note of whether she is still upright after 2022.
