I agree, its good to get a look at an inlet or harbor. I would not *rely* on it though, Google Earth Images can be out of date by a year or more.
EarthNC does overlays. Here is an example of
Ocracoke (pamlico side)
- "charts" (no overlay),
- "satelite" (to overlay charts on the google earth view)
- "map" (to overlay charts on a map view)
