jeff, if you have a known reference (sic) point, then you are not deducing
anything at all.

knowing the direction you are pointing and your speed through the water gives
you no known reference (sic) points at all. none.

btw, "known reference points" is a double redundancy saying the same thing over
again twice. reference points are by definition known. if you don't know what
they are and where they are they are not a reference point.

Of course DR requires a known reference point. If you weren't so convinced
navigation is impossible without a GPS you might learn how it works.

Now, now, jax .... don't get yer spandex speedo in an uproar .....
simply stated, you just don't know enough about actual navigation to
have the ability to carry on an intelligent discussion on the subject.
BTW, next time you look up "dead reckoning", "ded reckoning", "deduced
reckoning", read the whole definition.
Although I doubt you'll be able to comprehend the possibilities .......
