Jon Sanders was the first man to circumnavigate Antarctica solo, circling the continent twice in 1981 - 1982. For this accomplishment, Gate 17 of the new Antarctica Cup Racetrack has been named after him, with sector 17 named after the S&S 34 monohull Perie Banou, the yacht he had used during the circumnavigation. Sanders Gate is positioned mid-way round the Indian Ocean zone; the gate is close to where Sanders suffered a 180-degree knockdown. During the voyage, he passed south of the three great capes: Horn, Good Hope and Leeuwin, before rounding Cape Horn a second time. He turned north to Plymouth, UK and returning south around Good Hope and returning to Fremantle.
