Does not pick a knot
This page does not pick a knot for you. DNA, molecules, quantum braids and vortices stay off Decide.
Finished structure
No drawing of this exact knot yet. The written steps are the reference.
When this family fails, it fails as these. The recovered end still outranks the name.
Directional bite on a standing part — slide-test before you trust it.
- !Turns on the wrong side of the load
- !Failed slide-test, still used
- !A clove where a rolling or icicle third turn was the job
- !The riding turns are on the side away from the pull, so the hitch walks along the rope without gripping
- !The turns were not pushed hard together before loading, so it creeps a little at a time
- !The spar or loaded rope is slick, such as Dyneema or Spectra
- !The pull comes off at an angle instead of along the spar, dragging the turns out of shape
Turns on the wrong side of the load
Hitch will not grip and slides off
Both first turns must sit on the load side · step 01
Clove instead of rolling third turn
Wrong hitch — walks under along-line pull
The third turn is what makes it a rolling hitch · step 02
Failed slide-test, still used
Snubber walks and dumps the load back on the windlass
If it walks on the test, do not trust it · step 04
Hitch slides down the standing part
Check
- ?Two load-side turns
- ?Pull along the standing part
Then
- →Add a turn
- →Do not use on HMPE without a different plan
Turns on the wrong side of the load
Check
- ?Hitch will not grip and slides off
- ?Inspect step 01
Then
- →Retie. Do not dress a defective structure and call it seated.

Same failure class, different geometry. Open the plates — Diagnose still starts from the symptom.
What holds it
- ·A hitch is object-dependent. Remove the spar, cleat, ring or pile and the structure is usually the unknot.
- ·Bayman / Maddocks–Keller describe a no-slip regime from wrap count and friction. The prediction is approximate, and only for hitches.
What topology does not predict
- ·Closed-loop knot invariants (Jones, Alexander) do not say whether a clove hitch will walk on a smooth spar.
- ·No manufacturer working load is implied by wrap count.
- ·Wet, iced, or HMPE covers change friction — topology is silent.
Not for
- ·Joining two free rope ends — that is a bend
- ·A standing loop that must survive after the object is gone
- ·Slick HMPE standing part
- ·A hitch that must hold both ways equally
Same pattern, different job
