Anchoring tried Anchor buddy???
 

"Anchor weights, (also known as chums, kellets, sentinels, anchor
angels) have been used for generations to anchor boats more securely.
They almost double the holding power of the anchor and reduce the
working load of the anchor by up to 50%. They are an advanced
technique in safe, secure anchoring."

A handy gadget to have, but not a necessity. It is useful if you find
yourself anchoring in limited scope situations. However, I wouldn't
feel happy relying on one in high winds since its advantage goes away
when the rode is stretched tight.

It is if you do any serious cruising. Close in anchoring with limited scope
is a way of life.

Right.

However, I wouldn't feel happy relying on one in high winds since its
advantage goes away when the rode is stretched tight.

No one suggested that a kellet is advantageous in this situation. In a high
wind
situation one must let out additional scope. No substitutes for that.

I guess I'm not a serious cruiser. When an anchorage gets too crowded
for proper anchoring, I move elsewhere.

The web site makes a number of claims that might lead one too believe
you could get by with a smaller anchor in a blow. "reduces loads by
50%", etc.

Do you have a point?

This is the reason why the minimum anchor should not be used; if you
plan to anchor overnight (i.e. unattended) you should always go up at
least one size. My primary should hold up to 50 or so knots, but I
would generally have a second anchor set if I expected that.

My point is that what you call a "working anchor" does not become a
storm anchor simply by adding a kellet.

The above was quoted from the URL that was provided as a reference.

I think, and believe that it is common that - winds in excess of 40
knots you would be using more than one anchor and the URL:

http://www.fortressanchors.com/2nd_anchor.html

Illustrates 6 different anchoring situations, with 3 refering to storm
conditions.

I know more than one experienced crusier that do infact have a storm
anchor...the old Hershoff style fishermans anchor that was about 70
lbs which they called their "storm achor" generally these can be taken
apart and stored below.

Also many experienced crusiers go for one or two levels oversize from
that which is recomended for their boat as an anchor. And have an
min. or 2 and some asy many as 4 anchors.

An important factor in anchors is their ability to reset, it is
believed that "fluke"style anchors are NOT as good or capable as a
Bruce or CRQ style anchors, in ther resetting ability. Althought the
fortress exceeds them in holding power, with these style anchor the
bahamian style mooring makes sense....and why fortress includes a
discussion on secondary anchors.

GPS's and some depth sounds have anchor alarms.

This is the reason why the minimum anchor should not be used; if you
plan to anchor overnight (i.e. unattended) you should always go up at
least one size. My primary should hold up to 50 or so knots, but I

I didnt suggest that...but that "as the wind

as quoated from fortress anchors

The kelt does 2 things effectively:
1
It acts as a snubber
2
Keeps the chain on the bottom (when not in sorm conditions) and
exponentially increases the holding power (vertical pull out) of the
anchor.

I havent used this tech. myself but the cantanery principle does make
alot of sense to me. Is a kelt necessary? Since I dont know of many
that use one, probably not as they use other means of snubbing the
anchor line, if at all. If I had the experience of using one, then I
would decide if it was necessary. Thats why the original post sought
others thoughts, either in principle or from usage experience.
Still, i like the idea and it is something that you could probably
make yourself....I like those kind of ideas....

OK, no point but you just want to review everything you've read about
anchoring. That's OK, this all gets covered here every 2 or 3 weeks,
it seems.

Large Fortresses are gaining favor in this regard - more bang for the
buck (or pound). However, in a major storm the wind will shift, so
you need more than one anchor that can handle a serious load. A
friend is fond is fond of pointing to a small Danforth he keeps on the
stern and saying, "That's the anchor that held us in the 'Storm of the
Century.' "

He now carrys a large Fortress in the bilge, but for that storm he had
an array of three anchors set - the largest a 35 pound plow. All had
large scope - I think the Danforth was set in a mud bank so at low
tide it actually had negative scope!

1
It acts as a snubber

In light air it has similar effect. In heavy air, however, its
"snubbing power" evaporates. This is not a problem if rope is
included in the rode, but an all chain rode needs a proper snubber.

Of course, I'm not saying not to use the kellet in heavy air, only
that it shouldn't be relied on. In this case it acts as though you
had slightly more (or larger) chain.



2
Keeps the chain on the bottom (when not in sorm conditions) and
exponentially increases the holding power (vertical pull out) of the
anchor.

"Exponentially"??? I think not. In fact, it adds little if proper
scope is used. Its utility is also diminished if you use a
significant amount of chain on the rode. In other words, it can be
very useful if you use 6 feet of chain and 3:1 scope. If you have 50
feet of chain an always use at least 5:1 scope, the utility is diminished.



I havent used this tech. myself but the cantanery principle does make
alot of sense to me.

The "catenary principle" is often used when discussing anchors. It is
nonsense, only used by those who think a mathematical sounding word is
needed to explain what's going on. A catenary is the shape assumed by
a chain suspended by its two ends. A suspension bridge is the classic
example; a chain anchor rode is another. However, the reserve holding
power of a chain is in the part that is still lying on the ground, not
the part that is lifted up and is in the catenary shape. The reason
is this: if a rode is assuming the catenary shape, the difference
between that and fully extended (i.e. "rod-straight") is small, maybe
a foot or so. The "reserve" is in the distance the boat can move when
hit by a wave, not the force it takes to straighten out to chain.
Thus, when someone draws the picture with the nice curve, and says
"look at this catenary, that's what gives the smooth ride and holding
power," it means they don't really understand what's going on.

The kellet works because it forces the rode out of the catenary shape.
The rode can be viewed as two parts separated by the kellet: The
part nearest the anchor sees a shallow approach so it acts as if the
scope were larger. The part near the boat acts as if the rode had a
larger chain at the anchor end, which needs a larger force to lift it
off the bottom. However, both of these affects diminish in stronger
wind, as the kellet is raised and the rode straightens.


Is a kelt necessary? Since I dont know of many
that use one, probably not as they use other means of snubbing the
anchor line, if at all. If I had the experience of using one, then I
would decide if it was necessary. Thats why the original post sought

As I said at first, handy but not necessary. They are most useful if
you use minimal chain and scope. They can also be handy in reducing
the tendency to swing. I used one often on my first boat, which was
too small to carry all the ground tackle I wanted, and didn't have a
windlass. I used one a few times to reduce horsing on my second boat,
but also found I could just drop a weight to the bottom on very short
short scope to accomplish the same thing - this is sometimes called a
hammerlock anchor. Now I rely on a good anchor, 50 feet of chain,
and a windlass, and use a second anchor for security.

BTW, the friends I mentioned earlier have lived mostly at anchor for
the last 25 years. They frequently deploy a kellet. They've tried a
number of shapes, I think they now they use a set of diving weights
strapped around the rode. I'll ask them about it the next time they
pass through. (They're wintering now in Newfoundland!)

As it turns out my cruising friends just sent an email asking me to
pass on their web site to interested friends:

Ed has written a page about kellets, which he calls a sentinel:

That's misleading. In my limited experience using a kellet (once, and
it was an improv), you can extend the useful grip of your anchor, and
somewhat lessen the scope without loss of anchoring due to the simple
action of altering the geometry of the catenary.

But as someone pointed out, if the rode goes taut, you just have a
heavier rode.

It's an occasionally useful stop gap and a wee bit of insurance if,
say, you are anchored with a 15 lb. Danforth or equivalent "lunch
hook" and the wind pipes up. Lowering a kellet can buy you additional
prep minutes to depart or to ready a more appropriate anchor.

YMMV,
