You wanna talk about wild claims of knowledge laughed at by seventh
grade kids, here are some of jox's claims:

By definition, the Earth's surface is planar.

An ICBM has no navigation system.

There's no outside reference when using DR to navigate.

It costs $15,000/year to make 10gals of water/day with a shipboard
watermaker.

You must use an isp to read a usenet newsgroup.

The human head can take about a 7 G blow before death becomes certain.

A rhumb line is a straight line on any chart, Mercator chart (sic) or
otherwise.

A rhumb is distance between two points one compass point apart.

Alternators are (for all practical purposes) capable of only producing
one voltage, no matter the rpm.

If you can see outside reference points, then you KNOW where you are...

There is no such thing as a north seeking gyro.

Yes Jox, you are a riot.

Wow, I should have paid more attention to Jax's ramblings, they ARE
quite humorous! Now, in context, did he REALLY say that the earth's
surface was planar? The rest I can put off to just not knowing, but
that one is just foolish!

no, base kisser, the statement was made that across the distance from NYC to
Phildelphia the surface of the Earth is less than a meter or so from planer and
therefore there is no need to calculate curvature to know the distance to sail
a boat. "steve" didn't understand that .

"steve" also doesn't understand the meaning of the word "ballistic", which has
too many sylables. nor does he understand what deduced reckoning is, but
thinks it means watching for lighthouses and nav marks.

no does "steve" have any rational clew what cost accounting is (nevermind it
has been a thoroughly understood business principal for more than forty years),
nor does he have anyremote clew that differences (there are many, many, many)
between a generator and an alternator.

no does he have an rational clew how a gyroscope works.

"steve" has not shown himself to be rational.

If you can see outside reference points, then you KNOW where you are...

"steve", who is not known for rational thought, makes that claim that the above
statement is false, in essence saying that if you can see where you are you
still don't know where you are.

why "steve" says that is anybody's guess.

Here's the original reference, which, ironically, was in another thread
back in 2001 where Jox was also confused over Junger's description in
"The Perfect Storm".

http://groups.google.com/groups?selm...0mb-fz.aol.com

Excerpt:

In his book, "The Perfect Storm", Sabastian Junger makes note that the
(nervous) crew of doomed fishing vessel "cleaned the spark plugs" in the boat's
diesel engine before they set off. That single line instantly branded the
story as fiction and Junger as someone portraying himself as an expert he most
definitely was not. I understand that his portrayal of the thoughts of someone
near to drowning were also substantially at variance with reality. I
understand quite number of other variances exist in Junger's book as well.

I'm not sure Sabastian Junger is a mariner you'd want to go to sea with. I
know for an absolute fact that I wouldn't trust the navigational abilities of
anyone who claimed (nay, insisted) that vectors are "3 dimensional".

btw, if vectors are "3 dimensional", just how can they be used at a point on
the Earth's surface (which by definition is planer).

Spark plugs in a diesel = three dimensions for a vector. Tain't right, Marsha.
Tain't right.

The claim has been made by a poster on this ng who calls himself "steve"
that
diesel engines as used on commercial fishing boats are often torn down for
a
major overhaul after every trip to sea, about 700+ engine time.

Anyone here have experience with diesel engines in commercial fishing
boats?
do those guys really trust their lives to engines that won't go even a
thousand
hours? Anybody know why they do this?

A rebuild is done when necessary (obviously). I have heard that a 2-stroke
Detroit will last around 2500 to 3000 hrs (according to a specific owner).

Depends on the Detroit.

2-cycle DDs that are naturally aspirated will often run well past 10,000
hours with nothing more than routine maintenance and perhaps an injector
change or two.

Turboed engines are another matter. The basic rule of thumb appears to be:

0.5hp/cid or less - 5,000+ hours (10k is not unreasonable)
0.7hp/cid - 5,000 hours is reasonable to expect.
0.8hp/cid - 2,500 hours is reasonable to expect.
0.9hp/cid - 1,500 hours is reasonable to expect.
1.0hp/cid+ - You have grenades with the pins out in your bilge.
Do not drop the spoon.

A 6-71 has 426cid, and a 6V92 has 552cid. Do the math.

I know of one guy who claims 2,500 hours on 625HP DDEC-II 6V92, and is
****ed off that he's smoking a lot at this point and is generally exhibiting
signs that the engines are worn out. My reply to him is that he's been damn
fortunate and that a lot of engines of that size at that rating don't make
1,000 hours before they go "bang".

Karl, there you go being rational and what all. You are going to confuse those
what think that "naturally aspired" 2-stroke diesels don't have a supercharger
installed.

"Every trip to sea" could mean a month for some fishermen. Regardless of how
many hours are put on the engine during each trip, I'd think it would be
foolish not to do major preventative maintenance. Ever been 200 miles from
land?

Or is "steve" out to lunch?

Having grown up in the industry, I can say I've seen many DD's, Cats but
not to many sCummins run with well over 15.000hrs without a major O/H.
Longliners routinely leave their main runnng while offshore, They
usually start setting gear at sunset till late at nite, since the gear
is drifting after the last bouy/beacon goes over the side they need to
stay with the set till sunrise when haulback commences.

Some not all Offshore draggers will shut down and bring the nets back
aboard in the evenings if the catch drops off.4-7 days is the usual
trip, unless they do processing as well.

Offshore Scalloper's never shut down, its a 24hr operation with the crew
working shifts, and even the cook helps out with the haulback, culling,
and shucking, Depending on the area (Atlantic) the trip limits are set
by the co-op's, Like New Bedford won't buy from a boat thats been to sea
more than 10 days, but go down to Hampton,Va and the trip limits are 21
days.
Thats the way it used to be anyway. UD

thanks, dan, for the info.

now, we have the poster who calls himself "steve" claiming that commercial
fishing boats such as the Andrea Gail would "tear down" their engines after
nearly every trip of 4 to 7 days, about 100 to 170 hour engine usage.

of course. still, though, not sure just how one might clean the plugs on a
diesel engine, as the poster who goes by the handle of "steve" claims.
