Miles Hordern sailed alone in a 28-foot sloop across the Southern Ocean from New Zealand to Patagonia and back - a voyage of 13,000 nautical miles across the largest stretch of water on earth and a region of icebergs, gales and high seas. Six weeks later he made landfall on the coast of Chile and, after a chance meeting, embarked on a 1000-mile cruise southwards to survey channels and fjords in Patagonia, one of the last uncharted areas in the world. From Chile he sailed north on the Humboldt current, then west through the tropics on the return passage to New Zealand, arriving home some 18 months after he had left.
