Built in 1905 as a passenger ferry, she was converted into an auxiliary minesweeper by the Royal Navy in 1914. On 28 October 1915 she collided with HMS Sarnia off Cape Helles and sank within 10 minutes. The wreck was identified by Selçuk Kolay in 2022; she lies at about 72-74 metres, within technical diving depths.
Underwater cultural assets are covered by Turkish Law no. 2863. Diving at these sites is done only through authorized dive centers and in line with the published rules.
Distances are in a straight line and some coordinates are approximate; the route by boat is longer. Rows marked “Same area” are tied to the same anchor point in our records; we don’t know the real distance between them.
