Surveying Details
-----------------------------
11 May 1984. A wreck was examined on 18 March 1984 at 58 46 24N, 004 55 14W using W Orkney hyperfix - patts 3-1, 5-1,6-4. The NGR conversion gives eastings 231180, and northings 990960. The least echosounder depth was 72 in a general depth of 81 metres. No scouring was observed. The side scan sonar indicated a height of 9 metres, length of 100 metres (328 feet), and width of 15 metres (49 feet). The vessel is lying with its keel orientated 000/180 degrees, and is apparently intact.
