DR practice
jeffies, you are an idiot. please be quiet.
Hey jaxie, its also physically impossible to know absolutely where you are
even
with outside references. Its all a matter of how much uncertainty you're
willing to accept.

now, listen up, shen, one more fricken time. **IT IS PHYSICALLY IMPOSSIBLE

KNOW WHERE YOU ARE MOVING TO/FROM RELATIVE TO THE WATER AROUND YOU WITHOUT
**OUTSIDE** REFERENCES.
that is a fact of physics, shen. if you personally have so far been lucky
to
have not crashed into anything when you were drunkenly, blindly wandering
around in a fog in a rocky channel, that means only that you were lucky.
That
time. you didn't know where you were even if you thought you did. you
just
got lucky, that is all.
it is a physics thing, shen. you know, those damned laws of physics as
voted
on by corrupt politicians.
it
only involves speed,time, and heading,
shen, that *IS* the definition of ded reckoning. what you describe
"improved"
DR is in fact pilotage, a whole different breed of cat.
No jaxass. That is YOUR limited definition of DR.
What I described is NOT piloting, as piloting involves fixes.
In truth, the two can be and frequently are, used in conjunction, but
that's
beyond you -you're still at the "definition" stage.
