There are a number of cruising guides available:
South Pacific Anchorages
, Warwick Clay
Charlie's Charts of Polynesia, Wood
Landfalls of Paradise, Hinz, Howard
Guide to Navigation
and Tourism in French Polynesia
The first 3 are OK for some pre-planning but not very useful on a day to day basis. The Guide to Nav in FP is very good for the Marquesas, Tuamotus and Societies. It is available in French and English
. The English
version is harder to find. The pictures also make it a coffee table book.
As others have said, The Soggypaws compendium is a good reference and has some good details. In the season, the anchorages
listed can be crowded as everyone else is looking at the same coordinates.
