Does not pick a knot

This page does not pick a knot for you. DNA, molecules, quantum braids and vortices stay off Decide.

Schematic — the Alberto Knot family, shared by 2 knots in this catalogueFinished structure. Leader folded into a bight; braid wraps up the doubled section and back down over itself.

When this family fails, it fails as these. The recovered end still outranks the name.

FG / Alberto family

Braid wrapped onto a heavier leader, then locked so the join cannot hinge.

  • !Hinge at the material transition — the join clicks, then parts
  • !Wraps not packed on the heavier line before the lock
  • !Lock or tag on the wrong side of the braid, so the column unzips
Fails when
  • !Pulled up too loosely, so the wraps creep along the leader the first time it is loaded hard
  • !Braid tag exits the loop the wrong way, so the wraps stall and bunch
  • !Seated dry, or by pulling the braid tag instead of the braid standing line
  • !Wraps run past the leader tag onto a single leader strand
Geometry
  • Gapped or bunched first-set wraps

    The return cannot hide the gaps and the barrel pulls apart

    Alberto grip is even braid friction on the doubled leader · step 02

  • Barrel left short of the leader bight

    Walks on the first fish

    A hard opposing seat is the lock; an open Alberto is unfinished · step 05

  • Re-entry in the wrong direction

    Leaves a hinge instead of a locked barrel

    The tag must re-enter the loop the same way it entered · step 04

  • Leader loop left as a hinge

    The join clicks, then parts, under a hard run

    Inline barrels, not a folded bight, carry Alberto load · step 04

If you saw this
  • Pulls apart at connection

    Check

    • ?Barrel should look compact and uniform

    Then

    • Retie with tension
    • Consider FG after practice or Double Uni for speed
  • Return wraps cross randomly over outbound wraps.

    Check

    • ?Look for: Return wraps cross randomly over outbound wraps.

    Then

    • Retie keeping outbound and return ordered.
  • Tag exits the wrong side of the leader opening.

    Check

    • ?Look for: Tag exits the wrong side of the leader opening.

    Then

    • Retie with correct exit path.
  • Finished barrel can be pushed or telescoped after seating.

    Check

    • ?Look for: Finished barrel can be pushed or telescoped after seating.

    Then

    • Seat firmly wet; add wraps if material is slick.
  • Junction hangs in smaller guides.

    Check

    • ?Look for: Junction hangs in smaller guides.

    Then

    • Dress tags; consider FG or slimmer join for that rod.
  • Finished check failed — return wraps cross randomly over outbound wraps

    Check

    • ?outbound and return wraps stay ordered
    • ?tag exits through the leader loop in the required direction
    • ?finished barrel is compact without crossed braid

    Then

    • Retie. slip or uneven load concentration.
  • Gapped or bunched first-set wraps

    Check

    • ?The return cannot hide the gaps and the barrel pulls apart
    • ?Inspect step 02

    Then

    • Retie. Do not dress a defective structure and call it seated.
  • Barrel left short of the leader bight

    Check

    • ?Walks on the first fish
    • ?Inspect step 05

    Then

    • Retie. Do not dress a defective structure and call it seated.
  • Re-entry in the wrong direction

    Check

    • ?Leaves a hinge instead of a locked barrel
    • ?Inspect step 04

    Then

    • Retie. Do not dress a defective structure and call it seated.
Same family

Same failure class, different geometry. Open the plates — Diagnose still starts from the symptom.

This failed — start Diagnose

What holds it

  • ·A bend captures two working ends. Holding is constriction and the seated wrap or barrel — not a closed-knot invariant.
  • ·Unequal diameters and slick pairs (braid to fluoro) are material problems. Crossing number does not rank FG against a Double Uni.

What topology does not predict

  • ·A Jones polynomial does not pick a braid-to-leader family.
  • ·Published retention bands stay as cited on the knot record. This page does not invent one.
  • ·Guide-click and tag-trim are field geometry, not topology.

Not for

  • ·Attaching a single line to a spar or cleat — that is a hitch
  • ·Reading this page as a recommendation from Decide
  • ·Absolute thinnest guide-friendly profile (FG wins)
  • ·Two equal mono lines

Same pattern, different job
