Marble Wreck

An unidentified cargo ship, also called the Abu Saba wreck, reportedly lost in 1979 with a cargo of marble slabs. The reef tore her open. The port side has collapsed and the slabs lie across the sand from 8 m down to 18 m.

Dossier

Everything in this list comes from published dive-site descriptions. It drives the model's depth, condition and layout.

Name: Not published. Divers call it the Marble Wreck (حطام الرخام) or the Abu Saba wreck.
Type: Cargo ship used to carry marble
Lost: Reportedly sank in 1979. The reef tore it apart and its slabs spread across the seafloor.
Cargo: Marble slabs, still lying on the sand and in the wreck
Condition: Heavily broken down ("melted", in SSI's words). The port side has completely collapsed, with marble scattered everywhere.
Depths: Shallowest 8 m, deepest 18 m. Most of the dive is at 8–12 m.
Features: The masts are covered in oysters and Acropora coral. A coral-covered ladder sits near the rear of the wreck.
Life: Lionfish around the stern, close to the ladder
Conditions: Shallow and suitable for beginners. It is a short boat ride from Jeddah and is often paired with the Ann Ann wreck.

This wreck has no published name, plans, tonnage, survey or photogrammetry. A ScubaBoard member researching it for a maritime project found almost nothing. The geometry is a reconstruction that fits the documented depths and condition, and it should be corrected against your own footage.

Assumed

Hull: a small coastal cargo ship of 55 m length, 9 m beam and 4.6 m depth. It has a raised forecastle, two holds, two masts and the accommodation aft. It sits upright with a 12° list to port and is settled about 0.9 m into the sand.
The seabed rises from 18 m at the stern toward the reef at the bow. That puts the forecastle and mast stumps at roughly 8 m, which matches the documented shallowest depth.
The masts are shown broken off and the wheelhouse collapsed. Taller structure would reach shallower than 8 m, so this follows from the depths rather than from any photo.
The ragged edge of the collapsed port side is generated, not surveyed.
Slab sizes, count and spread are illustrative.
The ladder is placed on the starboard quarter, since the port side is gone.
Reef placement and the compass heading are illustrative only.

Dive mode and depth slider

The depth scale on the right is a slider. Drag it, click on it, or focus it and use the arrow keys. In the model view it raises or lowers the camera. In the dive it sets the depth your diver swims to, so the ascent-rate bars react if you rise too fast.
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. The regulator sound is synthesised in your browser.
The mooring buoy, line and dive boat are illustrative.

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, which is why colour fades with depth and distance. Switch on the torch to see colour come back up close.
Moving caustics, light shafts, marine snow, ambient occlusion and bloom. Growth, rust, marble veining and sand ripples are generated per pixel from world position, so the detail holds up close. Turn off Cinematic on slower devices.

What would sharpen it

A lap of the hull in video at a steady 2–3 m standoff, plus a few measured distances (stem to foremast, hold length). That is enough for real photogrammetry in Metashape, RealityCapture or Polycam.
A compass heading along the keel, and depths at the bow, the stern and the mast stumps.
The ship's name. A 1979 casualty record for a marble carrier lost near Jeddah would fix the hull form and superstructure.
The 1990s wide-angle photos by Kevin Metcalfe mentioned on ScubaBoard, which show the wreck before decades of further collapse.
