Can you navigate (lat and long) at night with a sextant and a compass, but
without a nautical almanac, sight reduction tables, the time of day, and
without knowing the names of the stars? The sextant has an error, but you
don't know what it is, just that it's off. You can keep your modern watch,
but you just replaced the battery and the time is wrong.

Does someone own a sextant? What model? I'm thinking about picking one up.

Are you talking about finding one location with one measurement or by
taking several measurements over a period of time? What degree of
error is acceptable? What a screwball question - do you even
understand what you are asking?

Get a cheap one, you probably will never master it as an instrument
and never understand the mathematics behind it.

You're another sockpuppet asshole, given the link you posted.... nothing to
say, with a lot of time on your hands. You're quite pathetic.

Keep changing identities if it makes you feel more like a man.

Why do you need all that stuff? The south pacific islander types
followed the appropriate star in the appropriate constellation and got
along just fine!

Did they? Maybe we just don't know how many of them got lost. ;-)

Well, possible. Of course those times it didn't quite work we didn't
hear about it...
