In my opinion the best cruising guide for this area, by far, is the Bansmeer and Breeding Cruiser's Guidebook for Pacific
Mexico, which has been available from Blue Latitude Press on Amazon.
https://www.amazon.com/Pacific-Mexic...0163484&sr=8-1
It covers the Pacific Coast from Mazatlan south and has the most excellent
charts available anywhere. I've scanned these
charts for use with
OpenCPN but I've heard that they are available in digital format for some systems.
I have a signed copy.
They also have a cruiser's guidebook to
Sea of Cortez.
