I threw out all the navnet info so not really sure. The PO showed me his raster charts that looked interesting, but he didn't remember how to down load them and I gave up on that ideas and went with Navionics on a tablet, which I thought was pretty good for the second year. I was pretty old school. In the 80's I spent 18 moths out cruising the Bahamas with a sextant and hand held compass, and a chip log and sounding lead. In the mid 90's got a lat long magellan handheld and thought it was the cats meow. I didn't get a charting handheld until about 2010. I still carry paper charts and except for two small areas of the new garmin where the fishing bottom contours were yellowed out, was pretty pleased with it. (and glad I still had the navionics on the tablet for those two areas. (here's a pic of the yellow at Portland Island. that should be contours and soundings.
in "Fogust" it's pretty nice to have. I turn it on in some crossing situations. Had to alter course early this year as I watched the approach of a newer American tug that should have been the give way vessel, but I slowed and altered course, and watched from a boat length away as he crossed. (no one at the helm or in the main helm cabin.)
