Cape Horn
"Rounding" vs "Doubling" the Horn

Rounding Cape Horn can be done on a day trip by helicopter or more arduously by charter power boat or sailboat, or by cruise ship. "Doubling the Horn" is traditionally understood to involve sailing from a point above 50 degrees South in the Pacific around the Horn to a point above 50 degrees South in the Atlantic, and then sailing back against the prevailing westerly winds to a point above the 50th parallel south again back in the Pacific—a considerably more difficult and time-consuming endeavor having a minimum length of 930 miles (1,500 km) for each leg. The 50th parallel south on both coasts of South America represent a set of benchmark latitudes of a Horn run, and is a region of the ocean that according to Herman Melville, "takes the conceit out of fresh-water sailors, and steeps in a still saltier brine the saltiest".
