WA ID 71017: Unknown wreck (UKHO 11267) Dimensions: 112.2m x 38.1m x 1.7m
This is a seafloor disturbance which coincides with SeaZone record 11267. This is a curious looking large seafloor disturbance anomaly on a very uneven and sand wave rich part of the seabed which might conceal possible buried wreck remains. The anomaly comprises a scattering of small dark reflectors, some with shadows and some without. These are visible as hard edged anomalies on a rough and uneven part of the seabed. There is a medium sized magnetic anomaly associated with these remains measuring 28nT which suggests ferrous material is present.

The UKHO describes this as an unidentified live wreck detected in 1995 with dimensions of 36m x 13m x 2.1m (SeaZone 11267). The survey data indicates that this is an entire wreck broken into two pieces lying some 20m apart and aligned southeast - northwest on a highly mobile and uneven part of the seabed. The wreck is associated with a large magnetometer deflection. This is a Live wreck in the SeaZone records.
