WA ID 71008 : Unknown (UKHO 11260) Dimensions: 33m x 10.3m x 3m
An unknown wreck comprising a large expanse of very broken up and dispersed remains located in the central southern section of Area THREE. This wreck was also identified in the ZAP phase dataset. From the sidescan sonar data, distinct, hard edged linear and curvilinear dark reflector anomalies with shadows are visible of various lengths and sizes. A possible hull edge is clear on one of the survey lines. Smaller rectangular and circular possible structural, debris and cargo anomalies can be seen both within the main expanse of the wreckage and also surrounding it in the sandy sediments up to 150m away from the main wreckage to the south. There is a very large negative monopole magnetic anomaly associated with this wreck measuring 346nT present across three survey lines suggesting a ferrous construction.
This area of the seabed has frequent large and mobile sand waves which could potentially be covering more pieces of debris and cargo associated with this wreck. The wreck is orientated NNE-SSW with no obvious scouring identified on the seabed.

The UKHO records this as an unknown wreck first detected in 1995 with observed dimensions of 40m x 8m x 4.9m (SeaZone 11260). The wreck remains are highly broken up and abraded, scattered across the seabed. The wreck is recorded as being associated with a strong magnetic anomaly and has a debris field in its southern extent. This is recorded as a Live wreck.
