Prudence thrives on circumspection
as oft', the patient mind, reflective,
reveals ideals of some perfection
as mere illusions of perspective.

Here's a picture I posted a while back showing the three second bowline.

Note that the starting orientation is ambiguous, so it's hard to tell what's which!
If you teach this method, I think it's easier to learn. Instead of making the loop,
worrying about which way to make it then putting the tail through, you simply make a
"T" and twist your wrist, to form the hole and send the rabbit through.
Indeed this & similar quick-tying methods ensure that the rabbit's going
in the right direction. But one should couple such methods with careful
articulation of how the knot works--of how the loop
nips & holds the end bight, and how to easily untie it.
his rabbit would run around the tree the wrong way. From What I understand
this creates a bowline variation (Dutch or cowboy bowline) that is strength
compromised.
-----------
strength isn't affected but security. i was taught (and have read);
that on shipping docks, when using the bowline; if the end (or toggle)
rubs briskly against something, it can invert the knot, and the load
falls, many times killing workers below.
But all of you can do more than read, right? --i.p., you all have ropes
and knowledge of how to tie these knots (of which this extended lamentation
re knot knowledge pays hommage to)?! SO, can YOU generate this mythical
failure mode? --I can't. Indeed, the supposed failure comes exactly
in the way that some folks are recommending TYING the very knot!
(the slip-knot method) Oh, I can capsize the Bwl, and see the knot
then become an overhand noose and slide against the object--but not
to the point of what I'd call a failure. Release the end, and what
happens should be the retying of the Bwl, right? As in ...
i make the bowline with the slipknot method; using that method,
it is a lot easier to see how the knot could invert and release.
I'm with you up to the "invert" part; I don't see then how it can
"release", since under the supposed condition the original SPart
is secured to whatever was holding the load, and the end is now
secured by snagging to something. I don't see the original SPart
coming undone (it's anchored to a winch or whatever), so release
the end from the snag and ... viola, one is now tying the Bwl
via the "slip-knot" method--and presumably with a long enough
tail.
What am I missing?!
Now, what I CAN see happening is that the EYE of the Bwl gets
snagged (and I can morEasily see an open eye snagging than a
loosEnd of rope!), and then the Bwl is "ring-loaded"--such that
the knot is effectively a bend: a "Lapp Bend", if tied the
"wrong" way (Bwl end outside!), or a mis-tied Lapp bend if
the reg. Bwl was the knot. The latter can readily spill.
A Dbl.Bwl (with either rabbit
) should preclude spilling
on ring-loading; various securings of the tail--of which the
so-called Yosemite Tie-Off seems most dubious (yep!)--will
also preclude failure on ring-loading.
groundies learn a half hitch, girth hitch, truckers
hitch, clove hitch, right angle, square knot, bowline, bowline on a bight, butterfly knot,
cow hitch, timber hitch, becketts bend (sheet bend) and prussic. I won't give them a
raise until they learn these knots. The shortest time has been two weeks, the longest is
13 months and counting .
Climbers need to know these knots plus swabish, distel, VT, bowline with a yosemite tie
off, zeppElin [Rosendahl's] bend, running bowline (why is this more difficult than a reqular bowline?),
figure 8, running 8 and double fishermans knot.
----------------------
i'd extend JP's just make a list of half hitches, to an olde,
secure standard a round turn and 2 half hitches? The strength would depend on what
you were hitching to, any uneasiness about security
I'd extend it to give a knot-securing complement: the slip-knot stopper
(or the Overhand stopper--the Slip-knot is handy when the knotted end is long,
and one prefers to tie the knot in the bight).
Some of those above knots can be made secure by tying a stopper knot in the end,
such as for the Clove, Cow, & Timber hitches.
As for "becketts bend", that's "becket bend" (a becket being a generally u-shaped thing, such as an eye splice).
Also, prefer the Dble of each--which helps smooth over the issue
of whether to tie the same-side vs. opp.-side version of the Sheet bend.
