I've been reading this in passing and just tried to figure out what had
been talked about in the past. What's this about 30-60' snubbers? Huh?
I'd say that my snubber and virtually every snubber that I've ever seen
is in the 10-15' range. Who's got a 30-60' snubber and why would anyone
ever suggest that you need one?

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?

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.
