I was talking w/ a longtime cruiser and he said he uses Google Earth to get a satellite view of whatever harbor he is approaching (South Pacific) and uses that to get familiar w/ the approach. Just saves the screen shot to pull up later even if he has no WI-FI.
Since Charts and Chartplotters are not always accurate, your GPS may put you on a reef.
Now I'm wondering if you use GOOGLE EARTH and the gps function together to place your boat on the display is THAT accurate? In other words, when the little icon shows up on the satellite view is that really what I'm doing?
I know the GPS on my phone shows where I am on the satellite view. It usually has me within 2 parking spaces when I'm sitting in my truck!
Works pretty well on the Bay too.
