Throughout the two World Wars Scapa Flow served as the base of the British Home Fleet. Access to these waters was guarded by a series of coastal batteries, booms and blockships. The blockships comprised old and damaged vessels which were deliberately sunk in position so as to form a submarine obstacle to deter enemy incursions. By 1943, the completion of the Churchill barriers, which cut off the eastern approaches to Scapa Flow, rendered the blockships obsolete. After 1945 some of the blockships were dispersed by explosive to clear the shipping lanes while many others were salvaged for parts and metal. The wrecks of several blockships remain on the sea bed and in the inter tidal zone.
(i) The Pontos (ND 49 NE 8002), a 3, 265 ton steel single-screw steamer was built in Glasgow in 1891. She was sunk in 1914 and now rests c.12m offshore to the SE of Water Sound.
(ii) The Clio (ND 49 NE 8006), a 2,733 ton steel single-screw steamer was built in Hartlepool in 1889. She was sunk in 1914 and is visible to the centre of Water Sound at low tide.
(iii) The Lorne (ND 49 NE 8008), a 1,186 ton single-screw steamer was built in Hull in 1873 and sunk in 1915. The wreck was later dispersed by explosives and only fragments now survive.
(iv) The Naja (ND 49 NE 8008), a concrete barge, was sunk in 1939 and lies to the centre of Water Sound.
(v) The Carron (ND 49 NE 8004), a 1, 017 ton single-screw steel steamer, was built in Dundee in 1894. She was sunk as a blockship in 1940 and now lies, partially buried under sand, to the NE side of Churchill Barrier #4.
(vi) The Juniata (ND 49 NE 8022), a twin-screw steel motor tanker, was built in Sunderland in 1918. Sunk in 1940, she now lies to the NE side of Churchill Barrier #4.
(vii) The Gondolier (ND 49 SE 8001) was a 173 ton paddle steamer built in Glasgow in 1866. Sunk in 1940, she now lies on the SE side of the barrier.
(viii) The Collingdoc (ND 49 NE 8005), a 1,1780 ton steel single-screw steamer was built in 1925 in Hill-on-Tees. She was sunk in 1942 and lies partially buried under the sand to the SE end of the barrier.
(ix) Unidentified wreckage (ND 49 NE 8003) stands above HWM.
