Also Dutton's Navigation and Piloting , thirteenth edition. Index,
deduced reckoning..see dead reckoning.

Section 8 Dead Reckoning
Introduction 801 " Dead Reckoning (DR) is one of the four main
divisions of navigation.....The term is derived from deduced or ded.
reckoning, the process by which a ships position was deduced or
compared trigonometrically, in relation to a known point of
departure.....

DR Defined 802 " Dead Reckoning is the process of determining a ships
approximate position by applying to its last well-determined position
a vector or a series of consecutive vectors representing the run that
has since been made using only the true courses steered and the
distance run as determined by log, engine revolutions, or calculations
from speed measurements, without considering current....."

"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".

guys, you can argue idiocy all you want, but it does not change the fact that
"dead" as used the context of navigation is incorrect usage as to what the word
"dead" means.

Absurd. You have nothing of significance as an authority, and you
certainly are no authority.

Is that particularly different than arguing with an idiot?

but it does not change the fact that
"dead" as used the context of navigation is incorrect usage as to what the
word
"dead" means.

With all that hogwash, you must own some very clean pigs. The meaning of any
word is what it is commonly understood to communicate. Nearly all naigators use
the term "dead reckoning" and understand what it means. Parsing the word "dead"
is a useful exercise only for NG trolls and those of us stupid enough to
respond to them.

grouch, because the word is misused and because the "common" usage of the word
implies high end precision, a whole generation of sailors believe it is
perfectly safe to wonder around among the rocks in fog, with just a compass and
speed indicator onboard. In fact, the USPS teaches that very nav system as
indeed a precision nav system. Nevermind, that just 25 years ago boats stew
ped enough to be caught near the rock in fog often ended up on the rocks before
the fog lifted.

you can call it Santa Claus, if you wish, but it ain't.

Are you saying "Bowditch" is misusing a term of navigation?
The only person who thinks it implies high end precision, is you. To imply high
end precision the term would have to be Dead-on Reckoning.

All your post do is confirm that you have done little if any navigation.

Tell ya what you do ..... start writing letters to all those writers and
publishers of books, on the subject of navigation; all the marina
operators; port authorities; sailors, etc., and tell them JAXAshby says
the are to henceforth use only the term "ded reckoning" when discussing
"DR" and that it only applies to speed/time/heading.
Come back in a couple years and let us know how your campaign is going .....

There you go. And since JaxAss has no credentials whatsoever in any
field, I'm sure the publishers will cite him in their upcoming editions.

hoary, this idea/this discussion is not new with me. It was once part and
parcel of all valid sailing courses.

we have a start, don't we?

actually, many, many, many writers have said the very same thing I said. It
is perhaps less of an issue today because gps's can be had for under a hundred
bucks, new.
