This is the homepage for the Alastor project, a wreck survey carried out by members of Queen's University Belfast Sub-Aqua Club ( QUBSAC ) as part of the "Diving with a Purpose" initiative of the Nautical Archaeology Society , Portsmouth. On these pages you can find a summary of the results of the 2003 and 2004 surveys, download the full report of either survey, or one of the press releases. Please use the menu bar at the left to navigate. 

The Alastor is a wreck lying at the bottom of Ringhaddy Sound in Strangford Lough, Northern Ireland. Built for Sir Thomas Octave Murdoch Sopwith by Camper & Nicholsons in 1926, she was a luxury diesel yachts 43 m long and displacing 340 t. After changing owner in 1929, she was eventually acquired by the Ministry of War Transport at the outbreak of WWII, and served as an armed transport and anti-submarine vessel throughout the war. She finally sank after a fire broke out on board in 1946 while being moored in Ringhaddy Sound for repainting. The photograph shows a sidescan sonar image of the wreck. 

The wreck was locally known as "Alisdair" or "Allister" for the 58 years between her sinking and the findings of this report due to a mistake in the original newspaper articles. Measurements taken from the wreck and historic background research carried out during the course of this project have now however proven beyond reasonable doubt that it is indeed the Alastor lying on the bottom of Ringhaddy Sound. The Allister was a 3600 t cargo freighter under Panamese flag which probably never came near Strangford Lough, and the Alisdair is still afloat and serves as a luxury home in the Loivre area of France.
