Dive Scapa Flow is THE definitive guide to diving the fabled wrecks of Scapa Flow, one of the world's greatest wreck diving locations. This completely re-written and updated centenary edition was produced to coincide with the 100th anniversary of the scuttle of the 74 warships of the interned German High Seas Fleet at Scapa Flow on 21st June 1919 - the greatest act of maritime suicide the world has ever seen. And don't forget Scapa Flow's war graves, HMS Royal Oak, torpedoed at the beginning of WWII and HMS Vanguard, which blew up in a catastrophic magazine explosion in 1917. Add in a U-boat, a boom defence vessel, an Icelandic trawler, a number of drifters, WWII vessels, many 'blockships' intentionally sunk to block the smaller channels into Scapa Flow during WWI and WWII and it becomes apparent what Scapa Flow offers divers.
