As far as Panama
goes, the best charts
by far in the Bauhaus cruising guide. Far more accurate than anything else out there. His cruising guide can be bought online. We got scanned in charts from the book but not sure if he puts those on his webwsite or if another cruiser scanned them.
Philosaophical point for me is that I would not have used the scanned charts if we had not bought the book. He is a small operation and I want to help him keep putting out the book.
The CM93 charts were pretty good for most areas, but, except for Bauhaus in Panama, they all pretty much have errors.
