WA ID 76145: Unknown wreck (UKHO Unknown) Dimensions: 10.1m x 7.8m x 1.8m


This is a possibly unrecorded small spread of potential wreck remains located in the central section of East Anglia THREE. The remains are visible in the sidescan sonar data as a small group of hard edged dark reflector anomalies with bright shadows in a uniform alignment. Parallel and opposing hard edged linear dark reflectors are visible that may represent structural elements/remains. There is a possible associated debris field located immediately to the southwest of the wreckage (76147) comprising six hard edged small dark reflector anomalies, one with a shadow and the largest anomaly measuring 1.6m. The full size and extent of the wreckage is not clear as it appears that they have been either highly degraded or buried by the surrounding mobile sandy sediments and sand waves. There is some slight scouring present to the north of the remains. No magnetic anomaly is in the vicinity of this wreckage which suggests it is composed of non-ferrous material.

From the geophysical survey datasets the wreck remains look to be sparse and likely highly degraded or buried by the frequent sand waves and surrounding sandy sediments. This is not recorded in either SeaZone or historical records.
