This book originated with Charmain Bibby OCC who offered notes of her 2003 cruise of Argentina to the Pilotage Foundation. This formed the first edition of a web pilot & augmented the earlier hard copy books of the South Atlantic Circuit & Havens & Anchorages published under the Pilotage Foundation. This current edition contains considerably more information, especially in southern Patagonia, & builds upon the original notes with the addition of information gathered by co-ordinating author Andy O’ Grady, Ulla Norlander & Pete Hill. They have written this work to help those who follow in their wake & the Pilotage Foundation is grateful for their selfless contribution & attention to detail. Without it, publications of this type could not take place. This new book would not have happened without the initiative & lead authorship of Andy O’ Grady. Magellan’s Strait divides Patagonia from Tierra del Fuego. Sailors considering entering the Strait should refer to Chapter 8 of Andy O’ Grady’s book Chile (RCCPF/ Imray) but should also be aware of the author’s comments at the start of chapter 6 to this book.
