Magellan Strait Pilotage

The Magellan Strait (Estrecho de Magallanes) is a passage located at the southern tip of South America, among the Chilean Patagonia, Tierra del Fuego Island and a number of islands to the West. It is the most important natural passage between the Pacific and the Atlantic Oceans. The Strait, in its whole length, belongs to the Republic of Chile and it is part of the XII Region of Magallanes and Chilean Antarctica (Magallanes y la Antártica Chilena). Its eastern access is surrounded by Argentinean waters. In accordance with Chile-Argentina international treaties of 1881 and 1984, the access and sailing from and to the eastern mouth is accessible to vessels of all nations, at any time and circumstances.

The transit of the Magellan Strait is done under compulsory pilotage for all vessels. Nevertheless and only if the vessel will do a Ocean to Ocean crossing, the use of pilots can be avoided between Punta Arenas and the occidental side of the strait.
