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. There is also a possible piece of associated debris located 65m to the west of the wreck (76146). The full size and extent of the wreckage is not clear as it appears that it has either been highly degraded or buried by the surrounding mobile sand sediments and sand waves. There is some slight scouring present to the north of the remains. There is no magnetic anomaly is in the vicinity of this wreckage which suggests it is composed of non-ferrous material.
1.2.7 Wreck 70911 51.
70911 is a discreet wreck remain located in the northern section of East Anglia THREE (Figure 17.23). The remains appear quite diffuse in the sidescan sonar data comprising curvilinear dark reflectors with bright shadows. One side of the hull outline is visible as a diffuse anomaly; however the wreck looks to be partially buried by mobile sands and is located in a highly uneven area of the seabed. The wreckage has dimensions of 31.3m x 8.1m x 1.1m. This has a medium-large magnetic anomaly associated with it measuring 49nT suggesting ferrous material is present. The wreck remains are visible in the bathymetry data as an elongated mound in area of sand ripples and is orientated approximately southwest by northeast.
52.
The UKHO record this as an unknown wreck, first detected in 1995 (SeaZone 11268). Survey data indicates the presence of an entire wreck, intact and upright, with small areas of minor debris surrounding the wreck. The wreck is orientated NNE-SSW and has recorded dimensions of 35m x 5m x 1.4m, which is comparable to the latest dataset. A significant magnetometer deflection has been associated with this wreck and it is recorded as a Live wreck.
1.2.8 Wreck 71012 53.
This is the remains of the HMS Fitzroy identified on the central western edge of East Anglia THREE; this vessel is protected by the PMRA (Figure 17.18). The remains consist of hull and deck superstructure present as distinct hard edged dark reflectors with large shadows. The wreck appears to be chiefly intact and upright on an area of the seabed with frequent sand waves and could be partially buried beneath mobile sediments. The wreck has dimensions of 70.5m x 15.3m x 5.5m.
54.
There is large scouring present in the sandy sediments to the north and south of this vessel. The southern end of the vessel looks to be reasonably well intact, either the stern or bow end, visible as a hard edged thick linear anomaly in the sidescan sonar data. There is also a large amount of scattered debris surrounding the wreck (76017, 76018, 76019, 76020, 76022, 76026 and 76027). The wreck has an associated
