It's called 'extrapolation' (look it up!). It's obvious
you have never exercised your brain and extrapolated
anything. This is a talent that is highly developed in
a real sailboat skipper. A small sailboat almost becomes
like an arm or a leg. It becomes an extension of one's
body and one can use input from the way it moves,
the heel, the roll, the sound of the water past the
hull, the sound of the wind, etc. to extrapolate
course and speed. If done regularly it becomes
second nature. Most any competent sailboat skipper
can do dead reckoning for long periods of time
using nothing but his senses even if he is below
most of the time.

From what I understood Donal to say, the person taking the test, is in an
enclosed space with no visual references and possibly muted noise, for the
entire time ..... not at all what you are describing.
What you describe is normal DR-ing, done by all, whether it be power, sail,
open cockpit or closed wheelhouse.

I once deduced my course so accurately and
made corrections as I went along only by
dead reckoning alone that after a passage of
18 hours from Beaufort N.C. I dead-centered
the ship channel through Frying Pan Shoals at
dawn - came close to hitting the sea buoy as a
matter of fact after ducking below to make
coffee and emerging to look over the bow at
it.

This is a talent NEVER developed by those who
sit isolated in a pilot house on the bridge.

G Once again, your lack of experience is showing. It's still and continues to
be obvious, that you have no conception of what goes on, onboard any type of
vessel, other than your own, and that you have little ability to relate that
experience to other circumstances, other than your own.
