You are (relatively) new around here.

The first thing to do is to plonk Jax into a nice padded
killfile. The second is to kill/ignore any thread
containing responses to him. Jax is a clueless boatless

Once you have our number one problem sorted you should take

~~ much snippage ~~

I got it - I missed the link you posted the first go 'round.

Interesting discussion.

What's a kellet?


A kellet is "that weight" we've been talking about. If you don't
incorporate "the weight" in the anchor rode, via chain, it can be
artificially applied by using a kellet. Weight is what makes the
catenary functional. As the following link describes, once the
catenary is pulled tight enough to start lifting the shank of the
anchor, the holding ability of the anchor *rapidly* decays. The
greater the weight of the rode, the more holding power and (within
reason) the more shock absorbing power .

Got it. Thanks.

I knew what it was, but I couldn't recall.

What happens during the interaction of forces on the rode would be

a way to simplified look at it is to consider the chain/rode/line to have

weight in
the center point and check how much strain it put on the end points when

the
weight hangs 20 feet, then 10 feet, then 5 feet, then 1 foot, then 1 inch,

then
1/10th inch. Just use trig to figure the forces.

So.... we just used intuitive trig to figure out why (1) we use scope
with an anchor and (2) why we don't tie boats to the dock with chain.
Now *that* is some real science......

And your "simplified look" does not apply.... an anchor rode does not
employ both ends at the same "Y" value.... therefore assumptions of
Y=Y'=0 do not obtain and is, therefore, the root cause of your lack
of understanding in this area. There isn't *anything* *attached* to
the middle.


But wouldn't the strain be equal at the arthimetical center and can be
equated to weight? It's really just another to figure energy
transfer, right?

I'm not totaly familiar with this so if I mess this up, it's an
electronic engineer with a math degree playing at mechanics, but
catenary defined means the shape of the line (or in this case rode) as
a curve. A funciton of strain would be weights at either end. Strain
can be defined as stored energy which is, I would think, distributed
evenly along the line to the end points. One way to define how much
strain is being applied would be to add weight to the middle and
measure the deflection.

At that point, it becomes a trig function - yes/no?


Yes. My point is that Jax keeps talking about this particular catenary
(and if properly applied, it isn't truly a catenary) as though both
ends are supported and hanging.... they aren't. The point of the
anchor rode is to fall from the boat at some small angle and end up at
the anchor at least parallel to the sea bed.

*********************ANCHOR

Don't know if this "graphic" will work, but this is what one should
have, not a true catenary..... if this is expected to hold the
anchor.


the forces get out of hand ********VERY******** quickly. Even worse, is

that
the weight in the middle (or chain) has momentum as the boat rocks, so the
"natural" position of the weight overshoots and makes for seriously high
g-loads.


There is no weight "in the middle" (other than the weight of the rode)
.... so you put two anchors on the same rode? Odd.

Using that concept, most people use kellets and think it is a good and
useful idea.


What's a kellet?


A kellet is "that weight" we've been talking about. If you don't
incorporate "the weight" in the anchor rode, via chain, it can be
artificially applied by using a kellet. Weight is what makes the

Look around after a squall and see which boats "dragged" anchor (i.e. pulled

Your math is wrong.


Starting with boat travelling at 8 ft/sec, a 2 g force will require 6
inches to stop the boat, and the boat will come to a stop in 1/8th of
a second.

To stop a boat travelling at 8 ft/sec within 1 second, the force
required is 1/4 g and the distance to stop is 4 feet.

To move a boat starting from standstill to 8 feet away within 1
second, the accelleration needed is 1/2 g and the speed attained at
the end of that 1 second of accelleration would be 16 ft/sec.

v(t)=at, d(t)=(1/2)at^2 and all that.

JAXAshby September 23rd 04 02:20 AM

the accelleration needed is 1/2 g

1/2 G (note the capitization) means a 11,000# strain on a 22,000 # boat. you
got 11,000# chain/chocks/anchor on your boat.

btw, yo-yo, the G-loads can be one hell of a lot higher than 1/2.

A wave surge isn't causing multi-G shock loads, jackassby.


Ok, let's see where we are. Jax admits that chain has shock absorbing
ability as long as it is a catenary... that it hasn't been pulled
straight.

Jax avers that all "rope" rode is "better" because it has shock
absorbing capability.

So, they both have shock absorbing ability until they are pulled
straight. Well, duh! The last thing we want to do in either scenario
is pull all the slack out of the rode... to do that would destroy the
ability of the anchor to hold, anyway.

Assumption that an anchor is some sort of immovable object isn't very
bright... even for Jax. Most all chain rodes won't support the kind
of tensions that Jax imagines take place, either. (But, then, this is
the sort of silly argument that Jax raged concerning sailors being
snatched into with safety gear... ah, but I digress.)

Jax has adopted some figures that 2G's will be developed in moving a
boat 4 inches at 8 feet per second.... yielding a 40,000# pull on a
20,000# boat.... obviously flawed, because no standard rode (chain or
line) or anchor is going to hold.... let alone standard deck hardware
and attachments... and boats *do* anchor. Thus, we can conclude that
Jax's figures and position are flawed and must be reconsidered. If
this scenario were anywhere near accurate, anchoring, per se, would be
operationally impossible. I suggest that Jax post his equations and
sources for numerical evidence, in the future, if he cares to make
such observably irrational conclusions and sway anybody to his
understanding of nature.

The point that seems to be overlooked is that what makes an anchor
*hold* is securing the anchor to the bottom while maintaining the
shank of the anchor parallel to the bottom. This is the whole
argument for sufficient scope. The material forming the rode can
either enhance or aggravate this situation. As I have previously
posted... and provided links to ...... scientific studies have shown
that when the shank of an anchor is pulled above the horizontal to 10
degrees the maximum holding power has been reduced to 60%, at 15
degrees it is down to 40% .. 10 degrees of yaw can increase pull by
60%.


Thus, one limiting factor in all of this is the ability of the anchor
to hold the bottom. A large anchor may only have a holding power of
3500#. Using an all line rode, this may decay to about #2100 or even
1400# depending on scope or rode angle. A 5:1 scope yields about an
11.3 degree angle and a 7:1 scope yields about 8 degrees... and thus,
has a tendency to raise the anchor shack to this angle.

The line/chain splice may further reduce rode strength from 12%-25%.

A kellet, line/chain, or all chain rode serves to solve the root
cause of anchor pull out.... the lifting of the shank. This is best
done by properly sized chain or a kellet.... if maximum holding power
is sought. Obviously, an all line rode will suffice in most instances
and often, a line/chain rode is employed simply for the purpose of
abrasion resistance.

To date,

Jax has posted no documentary evidence that any statement he has made
is either correct or germane,

Jax has posted no formulae or germane mathematical support of his
argument (straw men of 20,000# boats being jerked by a 40,000# load
notwithstanding),

I see no support for Jax's immovable object (anchor) theory,

I see no evidence that any ground tackle found on any boat other that
something bordering a ship will support anything remotely close to
40,000#

nobody has posted any documented evidence of deck hardware being
damaged solely by using an all chain rode,

nobody has posted anything documented or observable that would suggest
that an all chain rode has less holding power than an all line rode
nor that a properly sized all chain rode subjects a boat to any more
or less shock absorption than all line rode.


Rather than merely strike a pose as Jax has done, here are my:

Assumption that an anchor is some sort of immovable object isn't very
bright.


genie, who taught you that anchors are supposed to move?

JAXAshby September 24th 04 03:49 AM

yielding a 40,000# pull on a
20,000# boat.... obviously flawed, because no standard rode (chain or
line) or anchor is going to hold....


yup, but the nylon places the load of considerable time and distance.
therefore the shock load is several orders of magnitude lower.

let alone standard deck hardware
and attachments.




JAXAshby September 24th 04 03:52 AM

If
this scenario were anywhere near accurate, anchoring, per se, would be
operationally impossible


you, perhaps, have noticed that all the boats which drag -- due to an Act of
God -- in a storm are on all chain, or mostly chain with a few feet of nylon?

Of course you haven't. you have never seen a storm, except hidden in the back
of the closet in your bedroom at home.

JAXAshby September 24th 04 03:54 AM

I suggest that Jax post his equations

D = 16 T^2

S = T * A

A (one G) = 32 ft/sec^2

you can find these equations in a junior high school science class for advanced
students.


JAXAshby September 24th 04 03:55 AM

As I have previously
posted...


because *you* have posted something -- anything -- proves nothing at all.

what a self-centered turd you are for even suggesting such.

JAXAshby September 24th 04 04:01 AM

I see no evidence that any ground tackle found on any boat other that
something bordering a ship will support anything remotely close to
40,000#


therefore, genei clown, if *you* anchor on all chain and drag down on someone
injuring them you deserve to go to jail.

you need stretch, yo-yo. don't use all chain. unless of course you like you

they most certainly have. not here among the junior high school set, but it
has be documented far and wide, and with specific pictures.

this ain't rocket science, little boy. just ordinary knowlege for those with
an upper two digit or low three digit IQ.

there you go, genei. you WANT an anchor to move. It is called "dragging" and
it is NOT an Act of God. It is criminal negilgence if you injure someone with
your deliberate attempts to hit them by anchoring in an obviously irresponsible
way.

jail time, dood, for you.

but, genie, you don't ever anchor longer than a short to time fish, do you? In
other words, you zero point zero experience anchoring.



Doodles, the odds of YOU having any great degree of experience anchoring
in bad weather, with ANY particular set up, are in the realm of "slim to
none".

the accelleration needed is 1/2 g


1/2 G (note the capitization) means a 11,000# strain on a 22,000 # boat.


Capital G is the universal gravitational constant. Lowercase g is the
gravitational accelleration constant, the constant describing the
force which accellerates a mass towards the Earth's center as measured
at the Earth's surface. g is not constant everywhere on Earth because
Earth is spinning and because Earth is not a perfect sphere.

When one discusses forces on a body, one may compare these forces to
the force due to gravity, because gravity is familiar. A 2 lb mass
experiences a 2 lbf downward force from gravitational attraction on
Earth, thus a 1/2 g force (note lower case) would equate to 1 lbf. It
would not be possible to know what a 1/2 G force would be without
knowing the mass of the planet and the distance from the center, which
is why g is typically used instead of G since g already has that
information factored in.

you
got 11,000# chain/chocks/anchor on your boat.
btw, yo-yo, the G-loads can be one hell of a lot higher than 1/2.


The issue is indeed over the forces and whether the anchoring is
designed to withstand them and/or to minimize them.

Starting with boat travelling at 8 ft/sec, a 2 g force will require 6

1/4 second, not 1/8th. one hell of a difference.

but thanks for googling for hours trying to make an unproveable point.


Oh, quite provable indeed. I'm not aware of any specific links on
Google which would lead one to the equations involving accelleration,
velocity, distance and time, but it seems like you're interested
enough to research it for yourself. I remember them from high school
physics class many years ago, so there was no need.

The relevant relations here are v=at and d=(1/2)at^2. In this case,
we're specifying a=2g and solving to get an 8 ft/sec change in
velocity. Plugging in 32 ft/sec^2 for g and my (correct) answer of
1/8th second for t, we get

v= 2*32 ft/s^2 *1/8 sec = 64/8 ft/sec = 8 ft/sec, which was the
velocity given as the starting condition.

d= (1/2)*2*32 ft/sec^2 *(1/8 sec)^2 = 32/64 ft = 1/2 ft = 6 inches.

You had originally stated that for 2 g and 8 ft/sec, stopping distance
would be 4 inches; that math was questioned. I have provided not only
the correct stopping distance but the correct time. I stand by my
math.

in other words, odor vader, you contributed not a thing to the discussion about

not surprising, for you have never posted anything remotely related to sailing

Ah, I see your problem. You have already substituted the accelleration
constant g into d=16t^2 and multiples of g were apparently not dealt
with properly. Use d=(1/2)at^2 and you might get better results.
