....and if you go to Bowditch, you'll find another possible set of
groupings for the term "DR".
As I told jax, he had a definition, but not the absolute definition.
Thanks for bringing those up.

I think somebody is taking a beginning nav course.

Two references:

From the Dictionary of Nautical Literacy, published by International Marine ( a
division of McGraw-Hill)

Dead reckoning: The process of determining the position of a vessel by tracking
course and speed for a given time.
From the phrase, "deduced reckoning", the plot is called a "DR".

According to this source, Jax is half right. The process is called "dead
reckoning", but the hypothetical plot it produces can be called a "deduced
reckoning."

Then there's another source that indicates neither side of the argument has an
absolute leg to stand on:

From "The Sailor's Illustrated Dictionary"

dead reckoning (DR): The determining of a position by course, speed, and time
elapsed, but without a fix. A DR position is shownon the chart with a half
cirlce and a dot and the time the vessel was calculated to be in the position.
With any other information included, such as wind and current, it is called an
estimated position.
The term "dead reckoning" comes from "deduced reckoning" or "ded. reckoning",
which later became "dead reckoning."

According to this source, the hypotheticaly correct term realy is ded.
reckoning, (short for deduced). Unlike an assertion that anybody who knew squat
about navigation would never say "dead reckoning", those who are exposed to the
practice on an actual basis, in the real world rather than by reading about
boating, have probably never heard the technique called anything
except "dead reckoning."

the word "dead" can not be used in the context of DR, except in ignorance.

The expert speaketh.
Could you explain why? (and as per usual, I see you pulled the statement
out of context)

This is a real issue, for those who think "dead" is correct will also state
that ded reckoning is "dead bang on center", as in completely accurate, which
is a physical impossibility.


ROFLMAO

OK, jax .... we have you down to one word group for the discussion "ded
reckoning". NOW, give us YOUR definition of this word, so when the rest
of us with a bit more time navigating, will know the simplistic
methods/definition/words/process we must adhere to, should you start one
of your rambling discourses on the subject...... again .... in the future.

"ded" is the correct term, "dead" is not.



No entry in Lenfesty for "Ded Reckoning."

There is an entry for "Deduced Reckoning." It reads, "See Dead Reckoning."

No entry at all for "Ded" or "Deduced" in
Mckenna. Only for "Dead Reckoning".

Try Bowditch, you'll find some variations (at least in the older editions).
The point being that there are a number of definitions (if you will)
which tend to revolve around this term, and, as in many things
"maritime", many of them vary to some degree based on various national,
regional, vessel type (ship/navy/yacht), historical usage.
It is not as important that you have a specific definition for the term,
as it is that those discussing it, are aware there can be different
interpretations and that their discussion revolves around one particular
interpretation ...... something jax hasn't a clue, may be possible.

wake up, over the knee. it has been explained repeatedly in the last few dozen
posts on this thread.

pay attention, over the knee, on the off chance you might someday, somewhere go
out on the water.

way to go, gould, you found a source that thinks wondering around in a fog with
just a compass and a speed indicator will somehow keep you off the rocks.

or dum-dum, it used phonetic spelling of an ancient word.

geesh. some people's kids.

"ded" is the correct term, "dead" is not.

yeeeeeeeeeeeeeeeeeeeeeet, it is physically impossible to know where you are on
the planet using just a compass and a speed indicator. that some people
believe otherwise just goes to show you that some people are utterly ignorant.
the rocks don't care what you believe. not in the slightest.

"ded" is the correct term, "dead" is not.

gene, a reference point is a known quantity. that is the very definition of
the word "reference". if you don't know where it is it isn't a reference
point. and if you have reference points you are not DRing.

geesh. no wonder this guy can't convert inch-pounds to foot-pounds.

gene, you obviously don't know what the word "reference" means. go look it
up, you a***ole lazy clod, and then come back and try to ask your dumb,
idiot
dumb squat question again.

Have at it, genius, pick one....

ine:reference

... but none of them satisfy your usage's requirements.


What is a "specimin" ?

Of course someone that can't spell "specimen" should be expected to
express themselves using the proper word, either. Therefore, your
ignorant and inaccurate postings are understood, though not
necessarily forgiven.

Please try harder....

Maybe you should look up the concept "URL".... which is what I
provided and linked to a multitude of definitions... none, apparently,
that you have erroneously created in your own mind....

Sorry, reality is a bitch..... now you can go back to the safety and
security of JaxWorld.....
