Please don't regard him as an "expert"; he's getting quite old and thinks that "fadiddling fumble-putz" is a more accurate description.

    This is a really bad idea. It assumes that the charts are correct. I have a Navionics chart chip of France that was issued in the spring of 2011, and it does not show a large seawall at my marina that has been in place for AT LEAST 5 years. If you used this feature with this chart, on a dark and foggy night, you would have a hell of an accident, comparable to that one outside Charleston a few years ago.
    Bad idea. Make people do their own routing. I know that they can still make this mistake if the charts are incorrect, but letting the machine make the decisions is not good.

    I disagree pretty strongly, rxc. All the autorouting functions out there clearly suggest that their results should be checked by the operator, and they should be. But starting with a suggested route is easier than starting fresh, and probably results in fewer errors. Heck, a lot of boaters never make routes, and if this helps them get started, all the better.
    And no charting software or experienced navigator I know assumes that charts are always correct. I for one believe in using every source and aid available, but trusting none. Last summer I documented a breakwater in foggy Jonesboro, Maine, that hadn’t made the official NOAA charts or any electronic facsimile in over ten years, and it still wouldn’t be charted except that I made such a fuss! http://goo.gl/N7OGH
