So...... what the hell do you need all THIS crap for?

Because I run systems on research vessels.

G Kinda guessed something like that.

Personally, after a short period of time, I'd probably tell you just
where
you could shove your data, as it seems you are ready to blame the
helmsman
on scanty information, for something which may well NOT be his/her doing.

Ummm, Joe was saying that the helmsman could have been playing games
because he could get back on course before anyone figured it out. I'm
pointing out that - those days are GONE.

Actually those days were gone long before the newer systems. However, for
this type vessel the helmsman does little more than monitor things at sea as
the ship will be on autopilot 99% of the time and if the ship was on "hand"
steering, all of his actions would be watched.
(Not to say he couldn't screwup/oversteer, but odds are this is a
mechanical/electronic glitch since the action to induce a 15deg roll would
be a considerable, uncorrected screwup...... unlikely.)

My suggestion FWIW....analyze/collect your data ...... then ask the
people
on the ships what it means

Heh. Got news for you, *I* tell *them*.

G It's a two way street. When lucky enough to have this type of data, you
can generally get much more from it if you analyze it together, rather than
seperately.


I've seen it all, my friend. I've had the fun of hand steering an
icebreaker down leads in the pack, leaving a course track that looked
later like a drunken snail trail (similar to my normal helming, in
fact, but what the hell, they pay me...). I don't make assumptions
(except that most scientists are of limited competence outside their
specialty) until I have all the facts. WRT this thread, perhaps you
might consider the wisdom of that, before you flame me for something I
didn't say.

PDW

My first job in "65" was on a research vessel (long gone) and I've had
numerous occasions to observe the "scientist" "deckie" relationship since.
As for flaming you....G nah.....I just responded to what you *did* say,
and you'll note that in my first post I stated that I'm going to be
interested in finding out what really was the cause of this, once the
investigation is complete.
