This expanded 2nd Edition now includes more wreck details, photographs and a completely new section on aeroplane wrecks. If you are looking for a comprehensive up-to-date guide to Scapa Flow, this book is a must have. Scapa Flow has international acclaim as one of the top five wreck diving locations in the world and has more diveable wreckage than any other area in Europe. The shipwrecks are a mixture of battleships, cruisers and destroyers from the German High Seas Battle Fleet scuttled towards the end of WWI and the direct actions of the British Admiralty which sank a further 43 ships during both world conflicts to block the entrances to Scapa Flow.
