Why do you fear modern ways of navigating? If you should ever
decide to expand your horizons, you might embrace some of the
newer technology available.

Did you read what John wrote? People who trust their GPS blindly, hit
things that are not in the database. The database for the bay here is
pretty much useless anyway unless you just accept "don't go there" as
an answer.
The other issue is, if your electronics fail, do you just drop anchor
and call sea tow, hoping they can triangulate your position on their
radio or something?
I know people who think their Garmin Chart Plotter is all they ever
need. They don't even have a compass and no charts on board ... if
they could read them in the first place.

If that chart plotter craps out they are screwed, particularly at
night.

OTOH I navigate at night using local landmarks (radio towers, condos,
mangrove islands I recognize) and simply knowing where I am and where
I am going.

Greg, your feelings are pretty much exactly how I felt when I first got
into ocean boating. But once I graduated to the larger boats equipped
with GPS, chart plotters and radar I realized that technology had much
to offer over the old ways.

I still had paper charts aboard and obviously a compass but found that
the only time I had to use the charts was to program way-points into
the chart plotter before getting underway in the morning. Never had
to revert to navigating by charts and compass alone.

I saw that the Navy is going back to teaching celestial navigation to
their crews so somebody must think it is important. I suppose someone
pointed out the GPS satellites might only last a couple days in a real
war.
I am not saying these new things are not handy. I am just saying
everyone is depending on technology too much and forgetting basic
skills. It is not just boating. Stand next to a broken cash register
and watch the kid try to make change. It is scary.

Wars may be fought with joysticks but they will be won by a guy with a
rifle on the ground. You just have to look at Iraq to see that. We
bombed the **** out of them but we needed to occupy the country to
actually change anything, even if it was for the worse.

The Navy is teaching the basics of celestial navigation at the
Academy only to midshipmen but it's in no way intended to be a serious
navigation tool or method. Part of the reason is a public relations
thing after a Navy ship ran aground, but it had nothing to do with
failure of GPS or other electronic navigation systems.
In other words .... it was operator error.

Today, if the GPS system went down, half of our precision guided
weaponry wouldn't work either ... or be totally inaccurate.

To put your mind at ease: :-)


Military navigation systems (including those aboard ships) are not
necessarily dependent on GPS. The systems developed originally for
nuke subs are now part of the navigation systems aboard surface
ships, missles, etc. The system is called "Inertial Navigation System"
(INS) and can work in concert with GPS or independently without GPS.

Over the years the components and computers used for INS have been
perfected, miniaturized and are incredibly accurate even without
GPS input.
