Aussie Quickie

Australian quickie

Joining braided main line to a fluorocarbon leader. Tie a Bimini twist in the braid first; NetKnots says the leader then goes on in a matter of seconds.

Finished structure

Drawn from a rope model of this knot: which strand passes over which comes from where the rope actually lies.

  1. Tie a Bimini twist in the braid, then lay 15 cm (6 in) of leader beside the doubleThe braid is doubled by a Bimini twist, with an open loop at the left end of the double. The thicker fluorocarbon leader lies alongside the double, its end reaching past the loop toward the Bimini.

    Move 1 of 1Tie a Bimini twist in the braid, then lay 15 cm (6 in) of leader beside the doubleYou should now see: A firm Bimini at the base of the double, an open loop at its far end, and the leader lying alongside.

    Step 01

    Tie a Bimini twist in the braid to make a doubled section with a loop at its end, then lay about 15 cm (6 in) of leader alongside the doubled braid.

    You should now see

    A firm Bimini at the base of the double, an open loop at its far end, and the leader lying along the double with its end reaching past the loop.

    If it goes wrong

    Starting from single braid, or from a loop made with a quick knot instead of a Bimini. The leader wraps have too little to grip and the join slides under load.

    Fix: Tie a Bimini twist first. If its wraps have gaps or the loop slips when you pull it, cut it off and tie the Bimini again.

    Why: The leader wraps grip two strands of braid at once. The doubled braid gives them enough bulk to bite on, and the Bimini keeps the double from pulling apart.

  2. Starting just behind the loop, wrap the leader round the double 13 times toward the BiminiThe leader is wound thirteen times round both legs of the doubled braid, starting just behind the loop and working toward the Bimini. Its end leaves the last wrap on the Bimini side.

    2Thirteenth wrap
    Move 1 of 1Starting just behind the loop, wrap the leader round the double 13 times toward the BiminiYou should now see: Thirteen even wraps on the double, the first close behind the loop, the leader end at the wrap nearest the Bimini.

    Step 02

    Starting just behind the loop, wrap the leader around the doubled braid 13 times, working away from the loop toward the Bimini.

    You should now see

    Thirteen even leader wraps on the double, each touching the next, the first close behind the loop and the leader end at the wrap farthest from it.

    If it goes wrong

    Wraps crossing over each other or spreading apart, or wrapping toward the loop instead of away from it. A crossed wrap shows as a bump in the coil.

    Fix: Unwind back to the last clean wrap and lay the rest side by side again, moving away from the loop.

    Why: Wrapping away from the loop leaves the leader end at the far end of the coil, so it can come back along the wraps and through the loop in the next step.

  3. Bring the tag back along the wraps, pass it through the loop and pinch it thereThe leader's tag runs back along the near side of the thirteen wraps to the loop and goes down through the middle of the loop, where it is pinched.

    Move 1 of 1Bring the tag back along the wraps, pass it through the loop and pinch it thereYou should now see: The tag through the loop and held in the pinch, with all 13 wraps still in place on the double.

    Step 03

    Bring the leader tag back along the wraps to the loop, pass it through the loop, and pinch it there between thumb and finger.

    You should now see

    The leader tag through the loop and held in the pinch, with all 13 wraps still sitting in place on the double.

    If it goes wrong

    Taking the tag around the loop instead of through it, or loosening the pinch. The wraps spring open as soon as the tag is let go.

    Fix: Rewrap any wraps that opened, pass the tag through the middle of the loop again, and keep pinching until the leader is pulled in the next step.

    Why: The tag through the loop is what the wraps close down on. Once the leader is pulled, the coil traps the tag and cannot unwind.

  4. Hold the double and pull the leader, tag hanging free, then pull both lines hardWith the braid held still and the leader pulled, the thirteen wraps close up against each other into a tight barrel on the double, trapping the tag in the loop.

    Trim the leader tag closeThe finished Aussie Quickie: a tight barrel of thirteen leader wraps on the Bimini-doubled braid, the braid leaving to the right and the leader to the left, with the tag trimmed short at the loop.
    Move 2 of 2Trim the leader tag closeYou should now see: The leader coils packed into a neat barrel on the double, and a short trimmed tag at the loop.

    Step 04

    Hold the doubled braid firmly and pull on the leader, letting its tag hang free. When the coils have closed up, pull very hard on both lines, then trim the tag close.

    You should now see

    The leader coils packed against each other in a neat barrel, the tag standing out from one end, and no movement in the coil under the hard pull.

    If it goes wrong

    Pulling on the tag instead of the leader, or trimming before the hard pull. The coil looks finished but slips the first time a fish loads it.

    Fix: If the coil moves under the hard pull or the wraps bunch unevenly, cut the knot off and tie it again from the Bimini loop.

    Why: Holding the braid still while pulling the leader lets the coils close in order from one end. The hard pull on both lines sets them before the tag is cut.

Failure modes

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

Double-line wrap join

Leader wraps a Bimini double, then the tag returns through the loop.

  • !Too few wraps on the double — the leader walks
  • !Tag never returned through the loop, so the column dumps
  • !Tied on a single strand instead of a Bimini
Fails when
  • !Leader wrapped on single braid or a loop made without a Bimini twist, so the join slides under load
  • !Tag passed around the loop instead of through it, so the wraps spring open
  • !Coils not set with a hard pull on both lines before trimming, so they slip when a fish loads them
Geometry

  • Loose early braid wraps on the leader

    Walks later even if the lock looks tidy

    The first wraps are the bite — slack braid will not hold · step 02

  • Incomplete lock hitch

    Braid walks on the leader under a run

    The lock is not optional on this slim join · step 03

  • Long stiff tags left for the guides

    Click-through and then a dumped join
