Amyr Klink, whose sailing exploits have made him a hero in Brazil, tells of his daring single-handed circumnavigation below the Antarctic Convergence. Klink, who prefers to call his adventures "organizational challenges," relies on methodical planning, innovative (and sometimes controversial) technology, and raw courage as he takes on the non-stop white-knuckle dangers of the Southern Ocean. Humbly and handsomely he achieves his goal: to circle the Earth below the Antarctic Convergence alone.
