It is reported that only small parts of the keel and ribs still remain covering an area approximately 5m square. The remains are just visible at low water.

Event and Historical Information:
The RIVERTON was a 7345gt steel-hulled steamship. The ship was torpedoed by U1023 on 23 April 1943 at 50 25N, 5 25W. Three crewmembers were killed. The ship was towed to Swansea bay and beached. It broke in two and the stern portion, weighing approximately 500 tons, sank. The forepart was refloated and beached at Oystermouth. It was then taken to Swansea Dry Docks to be made secure for towing to the Tyne to have 90ft of the stern rebuilt. On 25 June 1945, the stern section was reported to lie bearing 019degrees from the Mumbles light (10ft of the upper structure was visible at low water). The wreck was marked with a buoy located at 51 34 19N 03 58W. A Notice to Mariners was issued to this affect (NM 514/45). The buoy was withdrawn in August 1949 and a Notice to Mariners was issued (NM1706/49). In March 1998, Trinity House reported that they were to undertake dispersal operations.
