jeffies, go READ it again, this time let your wife explain it to you.

what did you say your degree was in again?

You seem to be having serious comprehension problems, jaxie. Time for
another refill
of meds.

The chart in the New England Ropes brochure is quite clear, at least for
anyone with a
4th grade education. They don't bother to mention elongation below 4%. The
chart
shows "working elongation" of over 20% for filament nylon 3-strand. The
terms
"destructive" and "deformation" are never mentioned.

There is some feeling that after a major stress, perhaps over 25% of tensile
strength,
nylon rode should be replaced. This not a problem for a snubber, which can
be
considered sacrificial. This makes a good case for downgrading a primary
rode and
replacing it after a major blow.

jeffies, are you a lying sack of squat, or just too stupid to read your own
cites?

4%, dood, your cite states, just like I said. Unless, of course, *you*
don't
know what destructive elongation is. What did you say your degree is in?
we
would like to hear you say it again.

Yet another topic where jaxie can show his ignorance. NE Ropes says at
15%
of
breaking strength elongation is 15%. Marlow has similar numbers. But
what
would
they know?
http://www.neropes.com/techdata/3strand.pdf

One can debate whether 15% of tensile strength is a proper safety factor,
but
for a
snubber its not that critical. This works out to snubbers in the range
of
30 to 60
feet. Personally, the need to rig snubbers was one of the issues that led
me
to stop
using all-chain and go to a mixed chain/nylon rode.

ten foot of stretch on standard twisted nylon is about 150' to 250' of
nylon,
except under line breaking conditions.

Even more important than the "droop" is the limited (almost
non-existent)
extension
available to an all chain system. What its really needed is enough
nylon
to
allow for
5 or 10 feet, or more, of stretch.

The problems is
that above 35 knots of wind or so you have a straight rode.

Uhm, maybe for your boat. In fact, just last weekend I was anchored
out in 30 gusting 45 and neither chain+rope rode was bar-taut. On the
other hand, I was wishing I had a bit more chain on both because I
didn't have quite enough out for the weather (7:1 on a 7.5kg Bruce,
and 5:1 on a 25lb. CQR) as I'd anchored 8 hours before the peak of
the
blow.

To get a reasonable amount of shock absorption with all-chain, use a
chain hook on about 30-40' of light nylon laid line and veer out a
few
more feet of chain. You'll get all the spring you want, but if
there's
much fetch you don't want too slack a chain to save your bows from a
beating.

I've never used either a kellet or buoy, but I'd like to experiment
with both. Who has used which?

See Complete Book of Anchoring and Mooring by Hinz page 113. On the
ABYC
hypothetical power boat of 45 feet and 15 foot beam the cantenary has
1
foot of
"droop"per 100 feet of rode at 30 knots and 0 feet at 40 knots. If
your
boat is
smaller and has a smaller section it may be a little higher.

Hinz advocates the use of chain riding stoppers for all chain boats.
He
points out
that all chain rodes are very good at parting or destroying something
in
high winds.
They are also sufficiently noisey in high wind conditions to make
sleep
difficult.
