343.1 | PS series on anchoring | RDF::RDF | Rick Fricchione | Tue Jun 24 1986 13:06 | 14 |
| Practical �ailor has had a series on �ochors and a.cho.ing in their
last tXree i#sues. They have some tables whic( you can run thpo=gh
to figure _ut holding strength, a.cigr size, etc. It '`s quote
helpful. Sup.osingly they liked liGhtreight (i.e. Danforth) qUite
a bit. The weed and grass ,roblem arf dealt with on the article aPso.
In general they he,d the same opinion of CQRs, and didn't favor
Bruce too much either. Get the PS issue, or send me mail and Ill
photocopy it and send it to you interoffice mail.

343.2 | I favor CQRs | PULSAR::BERENS | Alan Berens | Tue Jun 24 1986 13:25 | 35 |
| Anchors and anchoring has been discussed previously in these NOTES. From
my experience and published reports, it appears that the CQR anchor is
the only anchor that will reliably reset itself if accidentally tripped.
In a couple of surveys of serious cruising sailors, all (as I recall)
use a 35 lb or heavier CQR as the primary anchor. Danforths tend to be
used as backups, perhaps due to the difficulty of stowing them on bow
rollers. Danforths also tend to plane in a strong current.
A recent issue of Practical Sailor reported on the anchors used by PS
readers, some 25% of whom either never anchor or never anchor overnight.
Only 9% reported using Bruce anchors. The vast majority use Danforths or
CQRs. I have heard some negative comments on Bruce anchors (there was a
comment to this effect in these NOTES).
Any anchor will have problems on a weedy bottom if it is too light. A
heavy anchor is needed to get through the weeds to the bottom. Due to
its substantial fluke area, a Danforth would have, I suspect, more
trouble with weeds than a CQR.
Various tests have shown that CQRs set quickly and hold very well. The
secret with any anchor is lots of scope -- like 7:1 minimum. A long
length of chain between the anchor and the nylon rode (assuming you
don't use all chain) helps holding and reduces chafe (we've buried 40'
of chain in Maine mud). Test results can be misleading, as holding power
varies substantially with bottom characteristics, scope, etc. The
overwhelming preference CQRs noted above is a strong recommendation.
If you buy a plow, get a CQR. The CQR is forged, the rest cast or welded
(ie, much less strong).

343.3 | Choose according to environment | GRAMPS::WCLARK | Walt Clark | Tue Jun 24 1986 14:38 | 22 |
| Alan prefers CQR, I prefer the Danforth (on my boat under the
conditions I cruise).
My reasons: I mostly anchor in sand/mud (rarely heavy weeds) and
the Danforth holds well there. Getting a Danforth to set in weeds
takes patience (very slow backing down -IE drifting at first) but
will work. I have never had a Danforth drag on me once set.
It is light (I have a boat that would suffer underway with an
equivilant CQR on the bow) which means I dont mind dropping/retrieving
and stowing the anchor from the cockpit (I can also use the sheet
winches to help break it out of the bottom and dont need an anchor
windlass).
Caveat:
If I had a larger boat needing an anchor in the 35+ lb range regardless
of type, assuming she carried her beam well forward to support
the weight of anchor/chain/windlass gracefully on her nose, I would
probably opt for the all chain-CQR myself since it handles weeds,
snags and setting quite well.

| See note 146.11 for a comment about Danforth and Bruce anchors.
One small request to anyone asking for advice: Generally you get some. I
for one would be interested in knowing what you finally decide to do,
and why. In this case, what anchor will/did you get, and what influenced
your decision?

343.5 | A vote for the fisherman | IMBACQ::SIEGMANN | | Wed Jul 02 1986 15:22 | 14 |
| For my regular working anchor I use a 45# fisherman type Hereshoff with
a bit of chain and 200' of 1" nylon. It sets in almost anything
with no hassle and will hold even on short scope if needed. I've
had the rode wrapped around the fluke all night in a strong blow
in Cuttyhunk (35-40 mph) and never knew it. On the other hand test
show that # for # the Danforth wins and indeed during winter mooring
I use a 35# ht, a 20 kilo Northill (I love this but not in weeds),
the 45# fisherman and a 45# CQR (I don't trust this one..). The
fisherman will move but not break out under duress and it stows
nicely up forward. My boat is a traditional ketch, wood, 35lod
10+' beam and full (well almost) keel.

343.6 | one CQR please | RDF::RDF | Rick D. Fricchione | Sun Nov 30 1986 19:04 | 15 |
| I've just opted for a 45# CQR for my O'Day 40. The swaying factor
for me was the reset capability of the CQR. The Bruce apparently
does not reset as well, and often needs to be pulled up and cleaned
in order to reset properly. If I read PS correctly, I would have
had to go to a66# Bruce to get the same holding power. Thanks,
but no thanks..
Besides Marine Exchange had one cheap. :-)
My second anchor is a Danforth 22S. It was my primary on t 33 I
had before this boat. I also carry a Danforth 12S for chuckles
(It was a good stern anchor on the 33).

343.7 | What about the new Danforth Deep-Set Plow? | MOORED::GERSTLE | Carl Gerstle | Tue Mar 29 1988 15:16 | 27 |
|
Just when I thought it was safe to buy a 25 lb. CQR as my new primary
anchor, Rule Industries (Danforth) had to bring out their new Deep-Set
plow clone to confuse me. Rule claims to have twice the holding power
with half the weight of an equivalent CQR. For my C & C 26 then, Rule
suggests their P700 (14 lbs.) anchor.
Granted, more weight (according to Alan's formula in 373.0) should
be better in an anchor, however the thought of lugging a 25 lb. anchor
and 20' of 3/8" chain around does little to make me feel happy. Does
anyone have substantiated information about the new Danforth plow
anchors?
Presently, I am using a Danforth 20H, which I know to be substantially
more than I _should_ need. The motivation to add a CQR/Plow is to
provide the usual 2nd good anchor, and especially an anchor which
will re-set itself reliably. My boat tends to sail quite a bit on
the anchor and although I have yet to accidentally break the 20H out,
I would surely sleep better at night with a plow down on the bottom.
Does Practical Sailor have any guidance on judging the holding power of
similar anchors? Any words on trusting a new anchor versus the tried
and true CQR? My new CQR is ready and waiting at Boat / US, the
question is ... should I bother getting it?

343.8 | Enough already | CSSE::COUTURE | Abandon shore | Tue Mar 29 1988 15:50 | 11 |
| Carl,
My opinion is that if you've got a 20lb. high tensile Dansforth
on a 26 foot boat, you're at overkill already for your cruising
area. My old O'Day 25 rode out Gloria on a 13lb. Danforth standard,
10:1 scope and weighted.
Tsk, tsk, next thing you know you'll be looking at power windlasses,
then more battery power to operate it, then a generator to keep
the battery charged, then a . . .

| re�-.2: ..... holding power of Danforth Deepset .....
Yes inde�dy, Danforth (Rule) does publish some impressive numbe~s. But,
if the holdinf power of�an�ancfo~ is i function of the area`of ivq
flukes, I don't see why�a Deeps�v gould hohd so mech better than any

muck muah denser a lit<le deeper? The recent CQR ads a~e also touting
very high iolding powe~ (well in excess of those reported in Practical

controlled tests before buying a Deepset.

343.10 | No Overkill Here | SALEM::MCWILLIAMS | | Wed Mar 30 1988 08:54 | 18 |
| re: 343.8
I would heartily disagree that having oversize ground tackle is
overkill. If you want to sleep well at night, there is nothing better
than knowing you have enough scope and enough weight on the hook that
it will reset easily.
We have a 25' and carry a Danforth 13, and a CQR 25 both with 300' of
1/2" rode with thimbles on the end so that in a pinch I can shackle
them together for more scope (or for use as trailing warp).
We I looked into getting the CQR for the boat, supposedly a CQR 20
would be sufficient for the boat, but upon asking around, I found that
many people had problems setting a CQR 20into certain types of bottoms
and suggested that we go with the heavier CQR 25.

343.11 | Flexibility is the design key | EXPERT::SPENCER | John Spencer | Thu Apr 21 1988 09:53 | 18 |

Deepset anchors have shanks with greater flexibility, and I understand the
theory is that this design helps both to reduce shock loads on the anchor
and to absord greater side forces before transferring them to the
fluke/bottom interface, thereby reducing the likelihood of breaking out
over time.
Whether this holds true in practice remains to be seen. I second Alan's
vote for some independent tests.
John.

343.12 | Any more input on the Danforth Plow? | WONDER::BRODEUR | | Thu Jan 30 1992 12:16 | 13 |
| Since the last few replies in this note referred to the "new" Deepset
Plow by Danforth, and I am considering bying a used one I wondering if
there were any comments concerning this anchor now that it has been
around for some time. PS recently did 2 articles on anchors and the
bottom line on the Danforth was that it was similar to the CQR in
design and holding power but they felt the quality and workmanship were
below the CQR standards. BUT I have the chance to pick up a 35lb
Danforth plow at "a good price" and was curious about peoples
experiences if any. I do know thaty Danforth asks top $$$ for there
plow (lb for lb much more money than the CQR). After reading and
talking to folks I think the Delta 35 would be my choice is I were
willing to buy a new anchor but.....
