Although I have not seen it, there is a companion spiral-bound chart book. The charts have numbered icons for points of interest which refer to the page number in the guide. Amazon has it for $54, $21 for the guide. http://www.cruisingguide.com/flkcb.html Coastal Charts for Cruising the Florida Keys by Claiborne S.

Note: I’m reading “Cruisng The Florida Keys” by Claiborne Young, and it looks like there is a very good chance we will see manatees and dolphins on the cruise along with a lot of other wildlife, and there are a lot of reefs to snorkel along the way.
