Default Demonstration footage of boat anchors

A few observations:

Humm...but wouldnt that apply to the Rocna too?
It would seem to and was one of my first thoughts of this test.
that is probably why an anchor with a mini float attached to it tend
or seems to be effect in keeping it in a good or better setting
position.


Mini floats have the drawback of detracting from the anchor's overall weight
underwater, and also are difficult to construct with any decent amount of
durability.

I would think that the Bulwagga would be righted on the bottom every
time given it design.


The Bulwagga has three flukes mounted in an equilateral arrangement. This
means there is no right way up

The drawback is that only 2 of its 3 flukes are ever in use. Furthermore its
design is difficult to make strong enough (flukes are just flat plate - catch
one in rock or coral and see what happens). It is however an excellent,
superior alternative to Danforth-type anchors.


I do believe that any anchors performance can be enhanced with the use
of a kellet or Anchor Catenary.


waynebatrecdotboats is largely correct is his assertations that kellets are
of little ultimate use. They suffer from a catch-22 whereby they work well in
light conditions, but by the time conditions are bad enough that you care,
the rode will have been pulled nearly tight, and the kellet will make next to
no difference - and of course it is at this point that you would probably
like it to.

Do not rely on catenary from either chain or kellet to absorb shock. Use a
nylon snubber to do this.

Kellets are good at reducing your swing radius, and their functionality
really ends there. Put the weight of the kellet into the anchor instead, so
you have a larger anchor, and you will see a much better return on ultimate
holding power.

A good angle of pull on the anchor should be attained by the use of adequate
scope.

Those interested in the theory can study the math he

That site considers most factors involved and arrives at a sensible
conclusion with regard to "the best rode" that we can support on the basis of
experience.
