How to Tie the Double Dragon Loop
Usage
The Double Dragon Loop is a strong, reliable end-loop knot that excels in high-load applications where security and resistance to shaking loose are key. Unlike the Bowline, which can work itself loose under repeated movement, the Double Dragon Loop holds firm even with modern synthetic ropes. It’s a good choice for marine work, camp rigging and general utility, though it can jam under extreme loads, making it difficult to untie afterward. Keep it off climbing, rescue and any other life load. If you want to see the structure move before you tie it, the Knot IQ app animates it step by step.
Why Learn the Double Dragon Loop?
- More secure than the Bowline, especially in dynamic or synthetic ropes.
- Holds its shape on utility anchors and general rigging, as it resists shaking loose.
- Simple to tie and inspect, reducing the risk of user error.
- Holds up well under tension, making it a great load-bearing option.
Common Uses
- Camp & Utility Rigging: Creating attachment points that resist working loose. Not for climbing, rescue or any life load — see Security Level below.
- Boating & Marine: Attaching lines to fixed points where stability is crucial.
- General Utility: Great for applications requiring a secure and reliable loop.

Notable Features
- Highly Secure: Less likely to shake loose than a Bowline.
- Works Well with Synthetic Ropes: Holds firm even on slippery materials.
- Strong Load-Bearing Capacity: Ideal for anchoring applications.
Variations
- Double Dragon Loop (Mid-Line) vs. The Double Dragon Loop: A version tied in the middle of a rope rather than at the end, useful for creating in-line attachment points. The same evidence gap applies to it.
Similar Knots
Bowline vs. Double Dragon Loop
- Pros: A well-known, easy-to-tie loop that’s widely used.
- Cons: Can shake loose under repeated movement, especially in synthetic ropes.
Butterfly Knot vs. Double Dragon Loop
- Pros: Creates a strong and stable loop that can take multi-directional loads.
- Cons: More complex to tie than the Double Dragon Loop.
Perfection Loop vs. Double Dragon Loop
- Pros: Forms a small, compact, and strong loop.
- Cons: Less commonly used in load-bearing applications.
History
The Double Dragon Loop is a modern innovation, often compared to the Tugboat A knot. It does not appear in The Ashley Book of Knots, but has been studied extensively by the International Guild of Knot Tyers. Its ability to maintain security in slippery, high-modulus ropes makes it especially valuable in marine and general rigging settings. Unlike traditional loop knots, it resists working loose, making it one of the most reliable loops for modern applications.

Security Level
The Double Dragon Loop is highly secure in everyday use, making it one of the better fixed loops for load-bearing utility work. That reputation is informal, though. Treat it as a good utility loop, not a rated one, and use a knot rated for life load when a person or a dropped object is the consequence. Under extreme loads it can also jam, making it difficult to untie — consider alternatives like the Bowline when easy untying is a priority.
Downsides
- Can Jam: May become difficult to untie after heavy loads.
- Less Commonly Known: Users must ensure proper tying technique.
Structure (Step-by-Step Instructions)
- Make a loop in the rope’s working end.
- Pass the working end around the standing part twice to create a double wrap.
- Thread the working end back through both loops from underneath.
- Tighten by pulling the standing end while adjusting the loop.
- Ensure the knot is secure before applying load.
Count the wraps before you load it. A single wrap instead of two is not a weak Double Dragon — it is a different, capsize-prone slip-knot variant (the Tugboat A precursor). Two wraps, dressed flat and uncrossed, or start again.
FAQ
How does the Double Dragon Loop compare to the Bowline?
The Double Dragon Loop holds better in slippery ropes, while the Bowline is easier to untie after loading.
Can the Double Dragon Loop be used for climbing?
No. Its whole reputation is informal — use a knot rated for life load instead.
What makes the Double Dragon Loop better than the Perfection Loop?
The Double Dragon Loop is better for high-load utility applications, while the Perfection Loop is more compact.
Is the Double Dragon Loop difficult to untie?
It can be, especially if heavily loaded. Users needing easy untying may prefer a Bowline.
Important Notes on Safety
- Ensure proper tying technique to maintain security.
- Be mindful of potential jamming under extreme loads.
- Inspect the knot before applying weight.
- Verify two wraps every time — a single wrap makes a weaker, capsize-prone knot.
- Do not use it for climbing, rescue or any load where a failure hurts someone.
