Turle Knot
Traditional fly terminal seating around the eye for alignment.
Intermediate · Monofilament / Fluorocarbon
Connection card
Turle Knot
For line → hook.
A collar around the hook eye so the fly sits in line with the tippet.
This card does not say how strong the knot is. A retention figure comes from a bench, in one material, at one diameter, tied by somebody who ties it all day — and the line in your hand is none of those. What it does tell you is whether the thing you have just tied is the thing the record describes.
What this plate is telling you
Traditional fly terminal seating around the eye for alignment.
Save this as a picture and it works with a dead signal and a nearly dead battery, which is when a joint is most often tied badly. The rest of this page — the steps, the seating sequence, the failure modes and the bench — is for the evening before.
Why this knot
What it earns its place with, what it costs, and what to reach for instead.
- Maximum strength critical tippet (modern compact knots often preferred)
- Braid
- Tying it on a fly with a straight eye
- Making the loop too small for the fly to pass through
- Passing the tag through the loop once instead of twice
- Pulling tight before the loop is fully behind the eye
- Orvis KnotBeginner
Ties tippet to a hook or fly with a small knot built on a figure eight
- Davy KnotBeginner
Tying a small fly to tippet with a quick, compact knot
- Improved Clinch KnotBeginner
Tying a hook, lure or swivel to monofilament line
Before you start
- ·For flies with a turned-up or turned-down eye. On a straight eye, use another knot such as a Davy or a clinch.
- ·Leave several inches of tag, about 10 cm (4 in), for the loop and the double overhand.
- ·Make the loop a little larger than the fly. The whole fly passes through it before the final pull.
- ·The knot closes around the fly's head behind the eye, so the tippet leaves the eye in line with the shank.
Step 1 of 4 · move 1 of 1. Thread the fly onto the tippet and slide it well up the line
Space plays or pauses. Keys 1, 2, 3 and 4 set the speed. Arrow keys change the move.

01.1
Thread the fly onto the tippet and slide it well up the line
- Hold:
- Left hand holds the tippet, a hand's width from its end
- Move:
- Right hand threads the fly on and pushes it up the line, out of the way
You should now see: The fly hangs on the tippet well clear of the end, with about 10 cm of tag to tie with, and its eye is turned up or down.
Thread the fly onto the tippet and slide it well up the line, leaving several inches of tag, about 10 cm (4 in), to tie with. Check the fly has a turned-up or turned-down eye.
The fly slides freely on the tippet, well clear of the tag, and its eye is bent up or down from the shank.
Starting on a fly with a straight eye. You can see the eye in line with the shank, and the Turle is meant for turned eyes.
Fix: Use a different knot for straight-eye flies, such as a Davy or a clinch.
Why: The Turle's loop closes around the fly's head behind the eye, so the tippet comes out of the eye in line with the shank. A turned eye leaves room for that.
- No loop formed to collar the eye — You cannot Turle without the loop. The loop around the standing part is the collar.

Tying procedure — Turle Knot
Step 01 / 4
Thread the fly onto the tippet and slide it well up the line, leaving several inches of tag, about 10 cm (4 in), to tie with. Check the fly has a turned-up or turned-down eye.
You should now see: The fly slides freely on the tippet, well clear of the tag, and its eye is bent up or down from the shank.
If it goes wrong: Starting on a fly with a straight eye. You can see the eye in line with the shank, and the Turle is meant for turned eyes.
Fix: Use a different knot for straight-eye flies, such as a Davy or a clinch.
Why: The Turle's loop closes around the fly's head behind the eye, so the tippet comes out of the eye in line with the shank. A turned eye leaves room for that.
1Tag end, about 10 cm2Fly, slid up the tippetStep 1 of 4 · move 1 of 1
Thread the fly onto the tippet and slide it well up the line
Hold: Left hand holds the tippet, a hand's width from its end
Move: Right hand threads the fly on and pushes it up the line, out of the way
You should now see: The fly hangs on the tippet well clear of the end, with about 10 cm of tag to tie with, and its eye is turned up or down.
Step 02 / 4
Double the tag back along the tippet toward the fly, then bring the tag behind and over the doubled line to make a loop.
You should now see: An open loop in the doubled line, large enough for the whole fly to pass through later.
If it goes wrong: Making the loop too small, or crossing the tag in front first instead of behind, so the overhand in step 3 twists and the loop will not open over the fly.
Fix: Undo the tag and form the loop again, behind and then over, a little larger than the fly.
Why: This loop is the part that goes over the fly and grips its head, so its size decides whether the fly can pass through.
1Large loop at the fold2Tag, back along the tippetStep 2 of 4 · move 1 of 2
Double the tag back along the tippet, toward the fly
Hold: Left hand pinches the tippet where the tag will lie beside it
Move: Right hand folds the tag back and lays it along the tippet toward the fly
- 1Behind, then over the doubled line2Small loop
Step 2 of 4 · move 2 of 2
Bring the tag behind the doubled line, then over it, to make a loop
Hold: Left finger and thumb hold the doubled line and the large loop
Move: Right hand takes the tag back, behind the doubled line and over the front
You should now see: A small loop beside the doubled line, closed where the tag crosses behind and then over it, and the large loop still wide open.
Step 03 / 4
Pass the tag through the loop twice to tie a double overhand knot, and tighten that overhand while leaving the large loop open.
You should now see: A small, tight double overhand knot on the tippet, with the large loop still open and able to slide.
If it goes wrong: Passing the tag through only once, or pulling the loop closed while tightening the overhand, which leaves no loop to put over the fly.
Fix: If the overhand has only one pass, undo it and add the second. If the loop has closed, slide the knot back along the tippet to open it.
Why: NetKnots shows the Improved Turle with a double overhand. The second pass gives the knot more grip on the tippet than a single overhand.
1Two passes through the loop2Small loopStep 3 of 4 · move 1 of 2
Pass the tag through the small loop twice, round the doubled line
Hold: Left hand holds the small loop open against the doubled line
Move: Right hand passes the tag through the loop, then through it again
- 1Double overhand, tightened2Large loop, still open
Step 3 of 4 · move 2 of 2
Pull the tag to tighten the double overhand, keeping the large loop open
Hold: Left hand holds the tippet and keeps the large loop open
Move: Right hand pulls the tag until the overhand closes on the doubled line
You should now see: A small tight overhand on the doubled line, and the large loop still open; pulling the tippet slides it smaller.
Step 04 / 4
Slip the loop over the fly so it sits behind the eye, then pull the tippet to draw the knot tight against the eye. Trim the tag.
You should now see: The knot sits behind the eye around the fly's head, and the tippet comes out through the eye in line with the hook shank.
If it goes wrong: Pulling tight before the loop is fully behind the eye. The knot sets on the front of the eye and the fly hangs at an angle.
Fix: If the knot has set on the eye rather than behind it, cut it off and tie again, checking the loop position before the final pull.
Why: Seated behind the eye, the pull comes straight down the shank, which keeps the fly riding level.

Step 4 of 4 · move 2 of 2
Pull the tippet to draw the loop tight behind the eye, then trim the tag
Hold: Left hand holds the fly
Move: Right hand pulls the tippet until the loop closes on the head, then trims
You should now see: The knot sits behind the eye round the fly's head, and the tippet leaves through the eye in line with the shank.

Seating sequence — where failures are born
The step list compresses the finish. Run these phases in order, one at a time.
01 Moisten
Wet the structure before any load reaches it.
Zero. Nothing tightens yet.
02 Load
Take up slack slowly until the wraps begin to gather.
Light and even — both ends moving together.
03 Dress
Watch the wraps stack in order; stop and back off if any cross.
Hold, do not pull. Correction happens here or not at all.
04 Set
One continuous pull to full seat — no sawing, no jerks.
Firm, single direction, standing line against the terminal end.
05 Trim
Cut the tag square, leaving a short stub proud of the knot.
None. Never trim under load.

Field notes — dark, cold, gloves
- ·Retie by feel first, light second — the seat is a tactile event, not a visual one.
- ·Gloves off for the dress phase. Fabric hides a crossing wrap.
- ·Wrong twice in a row means the material or the hardware is fighting you. Change one, not your technique.
Turle Knot — finished-state checks, on the shared reference layout
When this family fails, it fails as these. The recovered end still outranks the name.
Fine tippet at the eye, or fly-line to leader with a tube or nail.
- !Hitch path around the eye instead of through it
- !Single pass where two were the job
- !Gap at the tube or nail on a fly-line join
- !Pulled tight before the loop is behind the eye, so the knot sets on the front of the eye and the fly hangs at an angle
- !Double overhand tied with only one pass, which grips the tippet less
- !Tied to a straight-eye fly, with no room behind the eye for the loop to close

Nothing logged on this knot yet, so it starts on the bottom rung.
Good light, dry hands, a table. Until the sequence is automatic here there is nothing for the harder rungs to test — you would only be learning that difficult conditions are difficult, which you already knew.
How · Tie it, check it against the list, log it. Five clean and the ladder opens.
Nothing marked. Log it clean, or mark what happened first.
Strength, and where the number comes from
Not established
No published break test; the knot is chosen for fly alignment and no publisher states what it costs in strength.
Percentages come from published tests on their own line, their own knot-tyer and their own pull rate. Yours is a different system. Treat a figure as a reason to test, not as a result you already have.
