C-Map EPROMS have a few inherent problems......

1 - What do you do if the unit or batteries fail? No chart to
plot.....Not good...

2 - You can't draw on a C-Map plug the location of that new sandbar
you found 500 milliseconds after the keel did. I suppose you could
put a few waypoints around it, though.....

3 - The damned things are like the paper chart, though, in that they
are way too expensive to update often.....(see 2).

4 - You can scan your buddy's C-Map plug into your laptop like you can
that new chart he got. Oops....we're not supposed to scan in the
charts WE paid to draw, are we. I've given away a secret...damn.

Yeomans work really neat with your GPS on that paper chart:

It's as accurate as the width of your pencil lead.......even from a
cheap GPS.

Is a GPS map like the Garmin 176C a good alternative to carrying NOAA maps?
I live in the Chesapeake and would like to not have to carry large maps
around with me.

Worth the expense if I have the money?
