WA ID 71012: HMS Fitzroy (UKHO 11058) Dimensions: 70.5m x 15.3m x 5.5m


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. The remains consist of hull and deck superstructure present as distinct hard edged dark reflectors with large shadows.


There is large scouring present in the sandy sediments to the north and south of this vessel. One 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 some scattered debris surrounding the wreck (76017, 76018, 76019, 76020, 76022, 76026 and 76027). The wreck has a magnetic anomaly associated with it measuring 2409nT visible as a large distinctive dipole anomaly across two lines.


In the bathymetry data this wreck is discernible as possibly lying on its keel with some visible super-structure. It is orientated approximately north by south and located in an area of sand ripples. There are two areas of scour extending away from either end of the vessel and orientated approximately south-south-west by north-north-east.

70.4m x 8.5m x 2.1m Lobnitz & Co. Ltd., Renfrew


Sank by mine on the 27th May 1942 around 40 nautical miles east of Great Yarmouth. Most likely caused by a British mine according to UKHO records.


The UKHO records this vessel as a British minesweeper of 710 gross tons measuring 70.4m in length, 8.5m in beam and 2.1m in draught (SeaZone 11058). The HMS Fitzroy was built in 1919 and was sunk by a mine off Great Yarmouth on the 27th May 1942. The remains of the wreck are described by the UKHO as being partially buried and partially broken up, 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. This is recorded as a Live wreck.
