I didn't see anywhere, where Jeff introduced "pilotage" in a way to
change the definition.



..... and you, typically, took it out of context, and created a new
argument, which was unrelated to the discussion at hand, and tried to
pawn it off as "someone else said".
Lame attempt, try again.

over the knee, if you expand the definition to include gps charterplotters,
anything is possible.

same same if you expand the definition of breakfast eggs to include three
bricks of 24-k gold, you would be rich.

DR is speed vs time vs direction pointed, and your best guess as to where that
puts you. that's it, nothing more.

Some people believe that guessing as to current direction and strength and
guessing as to boat drift due to wind speed and direction improves their best
guess as to where they are, but it doesn't.


Oh boy here we go again.

You are wrong when you say "DR" is never dead on (but that's beyond

absolutely not. it is physically impossible. period. (except by random
chance, but that defeats the definition).

ROFL. Jax, we all ready know you don't understand the terms used in
"DR", or how it can be applied/used, and the possible variations in
meaning that others may have for the term and it's use.
How then could we expect you to understand that "DR" can be "dead on" in
many cases, but your total lack of experience and low levels of
comprehension put this possibility way beyond your ability to understand?

Too confused to state that in Layman's terms and present a viable counter
point???

like Ragu, "It's in there".

jax, you really,really do need help with "reading comprehension".
You can't just take what someone writes and interpret it to suit your
needs or point of view ..... go back and read what he said, then before
you write something, take the time to think what it means.

It is the height of stupidity (and thus just at your level) to claim that
aviation regulations have some relevance to sailing.


There is absolutely no qualitative difference between navigating an airplane
and navigating a boat, except the airplane also has an instrument to tell you
how far above the ground you are. none.


Don't know too many planes that can stop in midair and hover till they
figure things out....... (just for starters)

No jaxie, I didn't mention "known ladmarks" and I wasn't referring to
"pilotage." Its very simple: any DR plot begins with a known reference point
called a "fix." If you knew anything about DR you would understand that. I
would guess that most pilots know what their starting point is - that's a
reference point.
