The Strait of Magellan (Strait of Magellan) is located at the southernmost tip of the South American continent, surrounded by islands such as Tierra del Fuego. The Portuguese navigator Magellan first entered the Pacific Ocean through the Strait in 1520, so the name was given. The Strait of Magellan is winding, 563 kilometers long, the narrowest is only 3.3 kilometers, the widest is about 32 kilometers, the latitude is 71°W, 54°S. The Strait of Magellan is the most important natural channel between the South Atlantic and the South Pacific, but it is difficult for ships to navigate due to long periods of harsh weather, coupled with the narrowness of the Strait.
