How to Tie the Ashley Mid-Line Loop
Usage
The Ashley Mid-Line Loop puts a fixed, directional loop in the middle of a rope — no rope ends needed. It is built by tying a clove hitch on a bight and pulling a bight through, which leaves you with a loop that holds firmly when pulled from the standing part — the side of the rope under load — and comes undone with little effort even after heavy strain.
Why Learn the Ashley Mid-Line Loop?
Most people know this structure under another name: the cowboy bowline — a bowline with the tail finishing on the outside of the loop instead of the inside. That one flip changes the knot's behavior in a way worth understanding, and the mid-line construction means you can drop this loop anywhere along a rope for tensioning systems, hauling, and hanging gear.
Common Uses
Camping and Bushcraft
- The anchor loop in a trucker's hitch for tensioning tarps and shelters — its quick-release character means the system unties easily when you break camp. For tarp tie-outs, a dedicated line like our 1.8mm Reflective Guyline pairs well with it.
Search and Rescue
- A temporary mid-rope loop for hauling or attaching pulleys — for non-critical loads only, where weight isn't life-safety.
- Some vertical rescue teams use the long-tail form for stretcher rigging, with a tail of at least 6.5 ft (2.0 m) doubling as a backup connection and tag line.
Household / Workshop
- An everyday mid-line loop for hauling or hanging gear.

Notable Features
- Forms Mid-Rope: The loop is tied without access to either rope end.
- Strong Directional Hold: Excellent grip when pulled from the standing end.
- Very Easy to Untie: Opens with a push of the collar, even after hard loading.
Similar Knots
Alpine Butterfly Knot vs. Ashley Mid-Line Loop
- Advantage: The Ashley Mid-Line Loop unties exceptionally easily even after strain, and is faster to tie.
- Disadvantage: It is less stable than the Alpine Butterfly Knot under multidirectional tension — for a mid-line load that may pull from an unknown direction, use the butterfly.
Bowline Knot vs. Ashley Mid-Line Loop
- Advantage: Measurably better resistance to ring loading — a sideways pull on the loop itself.
- Disadvantage: A touch less stable under shifting, multidirectional pulls, and easy to mistake for its more famous parent, the Bowline Knot.
Other mid-line loops worth knowing: the Farmer's Loop, the Span Loop, and the Artillery Loop.
Security Level
Secure when tensioned from the standing-part side — that direction is the design case. A peer-reviewed 2020 test, Revision of Commonly Used Loop Knots Efficiencies (Šimon, Dekýš & Palcek), measured this tail-outside form resisting roughly 6.9 times more ring-loading force than the standard bowline — about 2,550 lbf (11.33 kN) versus about 365 lbf (1.63 kN) — while also documenting a tendency to loosen spontaneously under cyclic loading. Bear Essentials' read: this knot is a directional specialist — Ashley judged it on every-which-way mooring pulls where the exposed tail is a liability, while modern ring-load testing judged the one case its geometry is accidentally built for, and both verdicts are right about different loads.
Downsides
- Not Bi-Directional: The loop can collapse if loaded from the wrong direction.
- Loosens Under Pulsing Load: It tends to work loose under cyclic loading, so add a backup for anything consequential.
- Easily Confused: It looks nearly identical to a standard bowline — the only tell is which side the tail exits.
Structure
Underneath, this is a bowline-family knot: a single nipping loop that clamps shut under load. The defining difference from the standard bowline is that the tail (or the reeved bight, in the mid-line construction) sits outside the eye rather than inside it — the same structure you get from a clove hitch on a bight with a bight pulled through.
History
Clifford Ashley catalogued this tail-outside structure in The Ashley Book of Knots (1944), calling it "distinctly inferior" to the standard bowline — sailors, he noted, often tied it by mistake when mooring. Under the name Lapp Knot, the same structure has a documented history in Lapland, where it was used for hitching reindeer to sledges and suspending sheath knives.
How to Tie the Ashley Mid-Line Loop
Step 1
Form a clove hitch on a bight of the rope — no rope end needed.
Step 2
Reeve a bight of rope through the clove hitch to form the loop.
Step 3
Dress and set the knot to complete the fixed mid-rope loop. Check before loading: the tag end should sit on the OUTSIDE of the loop — if it sits inside, you have tied a regular bowline instead.
That inside-versus-outside check is the whole difference between this loop and a regular bowline, and it is worth learning to spot on sight. The Knot IQ app keeps the bowline family side by side so you can confirm which one you have actually tied. There are also end-tied and snap-style ways to reach the same knot; we'll cover those in their own guides. To drill it at home, the practice cord in our Knot Tying Kit is ideal for reps — practice cordage only, not rated for load-bearing or rescue use.
FAQ
What is the difference between the Ashley Mid-Line Loop and a standard bowline?
One thing only: the tail exits on the outside of the eye instead of the inside. Everything else — the nipping loop, the collar — is identical.
How do I know I tied it correctly?
Look at the tag end before setting the knot. On the outside of the loop means it is correct; on the inside means you tied a regular bowline instead.
Can I use it for climbing or rescue?
Not for life-critical loads. It can loosen under cyclic loading and can collapse if pulled from the wrong direction, so its rescue uses are limited to non-critical hauling and long-tail rigging with a backup connection.
Important Notes on Safety
This knot may capsize if it is not loaded from the correct direction — always tension it from the standing-part side. Because it tends to loosen under pulsing loads, back it up (a half-hitch with the tail around the eye legs, or a long backup tail) for any consequential use, and never rely on it alone for life-critical applications.
