We have been using
google earth for the past few years as an additional source for
navigation. In fact this has led us to tuck into numerous places in the
Sea of Cortez that are not in any guide
books. Using it when not connected to the
internet and a
GPS interface has been the closest thing to real time that we have seen. But with that said like all
navigation you better have your eyes open as well. In addition now
openCPN has a GE add on it makes it that much better. Lastly the GEKAP program allows you to make
charts from GE
screen shots. Fantastic stuff.
Certain areas are only passed over by GE at a much higher altitude thus missing some of the detail.
Safe sailing
