How much does chain stretch and is it important?
 

Some people on a thread below claim -- in essence -- that chain has no need to
stretch in an anchoring environment any more than it needs to stretch when used
to tie a boat to a dock or a rock on shore, while others claim chain
"stretches" at a rate of double digit percent of its length and thus is just
fine.

So, I ask of these people to tell us what the shock load is on a boat jerking
up and down a three foot wave, its chain rode pulled tight. Compare the
"stretch" of that chain with the stretch of an appropriate mixed rode in terms
of orders of magnitude difference in shock loads.

hint: it is a bunch. it is also so easy to understand than millions of high
school boys across the can do explain it.

What an asshole.
You obviously do not understand why you should pay out 4xdepth of chain.
A little understanding of force vectors then explains why the chain
cannot be pulled tight.

Please show the quote where *anybody* has posted that chain
stretches.

gene, *YOU* did. you may not understand that you did, nevertheless you most
certainly did claim chain stretches, for you claimed that an all chain rode
will not pull an anchor loose or the deck chocks off when the wind and waves
pick up.

The ONLY way for that to NOT happen is for the chain to stretch.

So, gene, just how much do you think chain stretches?

your narrow minded and
unsupported posits.

not my posits, gene, but rather the posits (your term) of the physicists, oil
rig designers, US Navy and every other person able to pass a high school
science course.

Please show the quote where I said I used an all chain rode.

the statement was not that you actually use anything at all to anchor, but
rather that you stupidly argue that all chain rode will not jerk the anchor
and/or deck chocks loose when the wind and waves pick up.

Physics, indeed!

yup, that is where the physics and mathematics of catinaries is taught.

You should have sat through a few intro classes of
logic, instead.

never took any *intro* courses in logic at the college level, but take quite a
number of upper level logic courses. (had the *intro* well covered in high
school)

so, NON-asshole, wanna explain to us the forces of catenaries?

Of course you don't want to even try. Obviously, by your statement below, you
don't have a clew of the forces involved. (dumb cluck that you are, you are
not even aware that the math and physics of the for forces on the catenary of
nylon rode is the very same as a chain rode).

Yawn, yet another classic Jax-Ass who gives a **** string of posts.

You still have that crappy little sailbote?

gene, STOP posting drunk. you talk in squared circles when you are drunk.
knock it off for a couple days and then come back.

Silly and foolish.... non-scientific and clearly erroneous conclusion.
The shortest distance between two points is a straight line..... too
bad gravity screws up your "ideal" scenario. Please return to Physics
101 and retake for passing grade..... thank you... goodbye....
