I am in the market for digital charts of the Bahama Islands. It is my
understanding that Maptech or what's left of it supplies these on CD-ROM. I
was also told that some editions of the Bahamas CD-ROMs included charts for
Bermuda and /or Monty Lewis' Explorer charts, or some combination of these.
If there are any users here familiar with these packages, I'd appreciate
hearing what is available, and which chart format is used for which sets of
charts (i.e., which charts will run under which charting software package,
etc.). All details appreciated.

The very, very best charts of the Bahamas are in the Explorer chart
books, available at West Marine among others. The good news is that
they are also available in electronic format via C-MAP-NT chips.
There is a USB card reader available for the CMAP chips which comes
bundled with software that converts your laptop into a chart plotter.
I mostly use it offline for planning purposes but it does support GPS
input and could be used for navigation. The Explorer charts, either
paper or electronic, are far better than Maptech's, no comparison at
all.

If you have a CMAP compatible chart plotter, be sure to order a
compatible chip and card reader combination.
