Dick, I couldn't agree more. Complacency is our worst enemy, and it is so easy for some to become completely reliant on such devices. I like this product for initial planning because it points out things you might not always be able to take into account easily, like currents for example. A known glitch that is being worked on now is that the near coastal routing can take the user inside some rather treacherous shoals. Logic tells us that other glitches are likely to exist within products of this nature, only to be found under the worst of circumstances. I like your warning about the level of competency required to even think about using such products.

In our book, use everything available knowing that no one tool is perfect. Then use your own skills, and powers of observation, to make sense of what the tools convey.
