WA ID 70752: Unknown wreck Dimensions: 14m x 2.8m x 2.7m
A distinct elongated conical mound orientated north-south is identifiable on the multibeam bathymetry with a possible indistinct scour to the north. Identified as a wreck, two parallel and distinct hard edged linears are visible forming an oval with some possible fractured areas amongst the dense sand waves. Fragmented dark reflectors are visible towards the northern end of the structure. A clearly defined irregular shadow indicates surviving structure with some height variation possible. A large associated magnetic contact, 529nT, suggests a ferrous structure and/or content. The wreck is located approximately 150m west of a pipeline. At the location of a previously recorded uncharted and unnamed wreck by Gardline and EMU.

Unknown Unknown Unknown
Little discernable internal structure can be identified other than two distinct parallel linears. However, a distinct height of 2.7m suggests some surviving superstructure. The wreck lies within an area of high sediment content which could have led to the partial burial of any surviving internal structure and remaining superstructure.
