light the next morning. The lightening excuse to learn astro is
BS. Learn it because you want to or take a couple extra handheld
GPS. Practice dead reckoning. Know where you are all the time.

Let's see...... calculator gone, long hand star calc's....add a
minute or two to the solution.
digital watch killed..... in that case I'm probably dead too so what
do I care.... always have a mechanical clock that you know the
error...no big deal, was done for years.
lights out?....lite a candle or wait till daylight.... what the hell,
it's offshore navigation, what's the rush....


And how did you check the error on that deck watch? Radio? What was
the error and how much does it change daily? Can't just do the time
check anymore. Damn lightening.


With all due respect Gary, I think you need a refresher course on
celestial. I wear a "windup" watch, and have two windup ship's
clocks. All of them are accurate to a minute a month, and have a pretty
consistent error rate. I generally set them once a week, so the error is
well under a minute. So, would you care to tell us what the expected
error would be for both Latitude and Longitude?

To be honest, I don't really buy the lightning argument either. But I'm
not sure some find fault in celestial because it is not accurate to 3
meters.

Jeff,

I'd be very interested in your opinion of where to get an inexpensive
but reliable "windup" clock/watch ?

Thank you,
Courtney
