How about a different take on this. We have gone through the Bahamas
from north to south a couple of times with Navionics
charts which are not wonderful but with the Explorer chartbooks (which are incredibly good). We have used the Navionics
most of the time but when there are concerns with depths, for example, we use the chartbooks and the Mark I eyeballs. It is a very easy place to pilot by eye. An example of our usage was entering the lagoon
on the south side of Mayaguana. You have to go in for close to an hour to get near the town dock
. We used the chartbook and eyeball to get in but kept a track running on the plotter that made it easier to get out (or if the light was not good).
