This is the story of two single-handed non-stop round-the-world voyages: Robin Knox-Johnston’s in 1968/69 and Ellen MacArthur’s in 2004/05. Although there were similarities – both voyages started and finished in Falmouth, for instance, and neither sailor was in a conventional race – the story is mainly one of contrasts, mostly as a consequence of thirty-six years of technological developments. These gave MacArthur the opportunity for a considerably faster voyage, but that didn’t necessarily make things any easier for her. When Knox-Johnston set sail in Suhaili, no one knew if it was possible for a human being or a boat to survive such a voyage; and when MacArthur commissioned her boat B&Q, many considered that a high-performance trimaran of that size could not be safely sailed around the world by one person.Whatever comparisons are made, the question as to which was the greater achievement is futile: both voyages were utterly remarkable.MacArthur is no longer 'the fastest', of course – her time has since been beaten by three Frenchmen – but she is still the fastest British solo circumnavigator, while Knox-Johnston’s record as 'the first' will be there for all time.
