UTM 30 N (WGS 84) X: 482056.2 Y: 6531960. Multibeam sonar survey data indicates that the wreck of Rotherfield lies along the eastern edge of Burra Sound at an orientation of 293° and the vessel appears to be resting on its keel. The wreck is largely dispersed but the outline of the vessel can still be identified (79.6m long, 14m wide and 5.5m high). Very little structural detail can be identified although the wreck appears to be better preserved at its stern to the south. Although the stern is covered in debris, substantial features are visible in the sonar data. An area of smooth plating just aft of midships may be a preserved part of the deck or a collapsed section of hull. There is a large amount of debris to the south and west of the wreck including a possible mast measuring 24m long which may or may not be part of the Rotherfield. [...] |

MULTI BEAM SONAR SCAN |
The multibeam sonar data records broken up remains, likely from the wrecks of the Inverlane and Budrie, over an area of seabed of around 4000 sq. m within Burra Sound, at depths ranging from 6.7m to 11.3m below chart datum. Both wreck sites appear dispersed and overlapping and cannot be separated in the data with certainty. However, the following interpretation may be supported by assertions by Wood (2008: 140) that the Inverlane sank directly over the Budrie and that some of the Inverlane’s hull plates cover the lower vessel.

MULTI BEAM SONAR SCAN |
UTM 30 N (WGS 84) X: 481881.6 Y: 6531895. The remains of what is thought to be the Urmstone Grange , lie on its keel in approximately 4.6m to 9.5m depth of water on a rocky seabed. The orientation of the wreck is 214°, roughly parallel to the side of the channel of Burra Sound. Although the wreck is largely dispersed its outline can still be made out as well. The wreck remains measure 94.4m long, 24.9m wide and 6.8m high, similar to the recorded dimensions of the vessel. There are several structural features discernible within the debris. In particular three boilers, forming a triangular pattern with two aft and one forward, are of a similar size measuring about 3m by 3.5m. Urmstone Grange is the only vessel in this area recorded as having three boilers. Approximately 6.5m forward of the boilers there are two circular objects, both with diameters of 2m, that may be mast footings. Further forward the vessel has largely broken up although there is some suggestion of preserved hull plating with ribs visible underneath. While there is no obvious debris field surrounding the main wreck evident in the multibeam data, debris may be hidden among the surrounding rocks. [...] |
