Re: NOAA To Stop Printing Nautical Charts

The common problem with electronic charts is that they are very often not accurate. The positions of land masses are from the same, often misdrawn graphics in paper charts. Actual GPS points input using these charts as a guide may well put you up on a highway or a beach. I have been looking at anchorages along the ICW and how the NOAA images line up with actual GPS points as recorded in the Doyle's anchor guide. Some land masses are shown where there is actually 30' of water:-)
If you are placing complete trust in the video game, you may not notice that things are not as they should be. Dead reckoning traits that we old farts have come to internalize over the years, usually set off some alarm bells. Things like keeping an eye on depth, noticing ranges on things that should align, and reading the water, at least to me, are essential to being confident of position. There are more clues than just a computer screen to tell you if you are where you THINK you are.
