I don't think one exists. "World Cruising Routes" by Jimmy Cornell provides good routing info and is probably the best guide you will find.
There also is the old Charlie's Charts
, but that is really for once you reach Marquesas
and then points farther westward. Typical route
is to sail (motor mostly, in our case in 2008) from Panama
Islands. Then Galapagos
, usually Hiva Oa. There is also a French guide for French Polynesia
that was pretty good, but our copy contained more than a few misprints and typos -- such as saying SE when the author meant SW or NE and having digits transposed in waypoints. Unfortunately, I sold that guide and do not remember the name or author; but I would be hesitant to recommend it anyway because of the typos it contained.
