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
Drawn from a rope model of this knot: which strand passes over which comes from where the rope actually lies.
When this family fails, it fails as these. The recovered end still outranks the name.
A round turn or stacked turns take the load; the lock only keeps them there — and still breaks by hand.
- !No round turn — the lock is asked to carry surge
- !Turns not stacked, so the hitch walks on a tide
- !Expected to jam when the job was a release-able dock line
- !Left bare on a boat that surges or swings on its line
- !Tied round polished metal or wet plastic
- !Second turn taken the opposite way round
- !Tail left short, so it pulls through the turns as the hitch slips
Turns not crossed
This is not a clove and will not hold
The second turn must cross over the first · step 02
Spread / walking clove
Walks off the rail under cyclic load
A clove holds only while the turns stay stacked · step 03
Left unattended on a tide
Fender or line on the bottom
Animated Knots: not a mooring plan · step 04
Hitch walks off the spar
Check
- ?Turns stacked and dressed
Then
- →Back up or replace with round turn and two half hitches
Turns not crossed
Check
- ?This is not a clove and will not hold
- ?Inspect step 02
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
- ·Unattended mooring
- ·Cyclic snatch
Same pattern, different job
- Diagram in reviewConstrictor Knot
Add a riding turn and the clove becomes a constrictor that jams.
