The steel trawler Othonna was built in 1899 by Duthie J. - John Duthie, Sons & Co. - Torry Shipbuilding Co. Ltd., Aberdeen, Yard No 200. The trawler was registered and fished out of Milford Haven until requestioned by the Royal Navy and put into service as a mine sweeper.
UC-41
On the night of April 18/19, 1917 UC-41(Kurt Bernis) laid a mine line, consisting of 7 mines NE of May Island.
THE LOSS
HMT Othonna was part of a minesweeping trawlers based in Granton which would sweep and destroy mines in the Firth of Forth.
On the morning of the 20th of April 1917, one of the the Engineers onboard HMT Othonna, Neil McKay or George Davies, reported that the engine was defective and needed repair. The minesweeping trawlers HMT Brecon Castle & HMT Izaak Walton were sent a message saying it would be about two hours to make repairs.
A message came back saying that the mine sweeping patrol would be sweeping two miles from the North Carr Light Ship. HMT Izaak Walton was ordered to stand by HMT Othonna until repairs completed.
Shortly after, at 6 a.m. HMT Othonna reported engines were now repaired so set off with HMT Izaak Walton for the sweeping area.
At about 09.30 a.m. two trawlers approached the sweeping area and the unit was sighted about four and a half miles north east of May Island.
As the two trawlers got nearer it was observed that the unit had the signal hoisted ''Mines in sight''. Two mines were observed on the surface and the unit were firing on them. HMT Breacon Castal, via semaphore, ordered HMT Othonna to take station to the windward and engage.
The skipper Alex McLeod was in the wheelhouse, with 2nd Hand Robert Marr. The mate had gone on deck to fire at the mines with a Winchester rifle. As the trawler was about to get into position the HMT Izaak Walton crossed the bow of HMT Othonna and caused her to stop and at that moment HMT Othonna struck a submerged mine.
The skipper and 2nd Hand found themselves in the water having been blown out of the wheelhouse. Just as the skipper righted himself with his lifebelt, he saw the stern of HMT Othonna out of the water as the vessel sank. They, together with two other crewmen, were picked up be a small boat from HMT Izaak Walton.

THE WRECK
Wreck Card 2970 was created for HMT Othonna in 1919 and stated ''SUNK IN 561500N, 023000W, APPROX. (SNO GRANTON). INS WK.'' This was added to the chart as a dangerous wreck.
It was reported that no wreck was found during a sonar search in 1955 and again nothing found during a search in 1960 from HMS Scott.
Two more searches, one in 1977 by HMS Shipham and one in 1994 by Oceanics UK Ltd also failed to find the wreck and the wreck card was amended to ''DEAD''.

Footnote. The above chart shows a second wreck SE of the HMT Othonna charted position. This wreck was also added in 1919 as Wreck Card 2968 and was ''Unknown''. This wreck was also not found in the above surveys and was amended to ''DEAD'' This maybe a duplicate record for HMT Othonna.
