The tale of Crusader, the jet-powered boat of 1952, appears to be a simple one about the ambition of John Cobb and Reid Railton, two unassuming but deeply gifted men, to break the water speed record on Loch Ness only for their efforts to end in tragedy. In fact the story behind that fateful outcome - Cobb's death on his first high-speed run - is a complex web of clever design and inspirational endeavour mixed with personality clashes and errors of judgement. After many years of research, including access to a wealth of original documentation, Steve Holter unravels the entire saga of the ill-fated Crusader and presents a compelling detective story.
