ALAN GURNEY, a yacht designer and photographer turned full-time writer, lives in Suffolk. He is the author of the highly acclaimed Below the Convergence and the widely praised The Race to the White Continent. Both books are available from Norton.
"...looks as if it might do for magnetic north what Longitude did for, well, longitude." - Erica Wagner, The Times "...[I]t is in these chapters on Knight that Gurney shows best what he is capable of. Without laborious analysis, he charts a steady shift from theoretical to empirical science; equally deft is he in his narrating of Knight's capabilities as a business man (which easily matched his capabilities as an inventor). Gurney's digressive style also works to his advantage in his discussions of Knight, as he gives tantalizing suggestions about the ways in which accurate navigation, or rather, the ability to intercept escaping ships at sea and the counter-plunder, bolstered not only the naval supremacy of the British fleet, but also the national exchequer."
