How to Tie the Exploding Release Knot
Usage
The Exploding Release Knot is a remote quick-release rig for holding a boat or floatplane at a dock so it can be freed with one pull on a tail line. The pilot or operator secures the craft, routes the free tail back to the cockpit or dock position, and when it's time to go, one sharp tug makes the whole hold "explode" open — the craft is released instantly, and nobody has to walk back to the knot.
It belongs to the family of exploding knots: rigs built so a single deliberate pull releases everything at once, leaving no tangle behind. That makes it a tool for attended, temporary holds only — it is explicitly not a knot for leaving anything tied up unsupervised.
Why Learn the Exploding Release Knot?
If you ever launch a small boat solo, or hold a floatplane at a dock while you climb aboard, the problem this knot solves is real: you need the line to hold right up until the moment you're in position, then let go completely without you returning to it. A remote single-pull release turns a two-person departure into a one-person job.
Learning it also teaches the core tradeoff behind every quick-release rig — a lesson worth practicing on the cord in the Knot Tying Kit before you ever trust it dockside.
Common Uses
Aviation
- Holding a floatplane or aircraft at a dock or tie-down point, released from inside the cockpit by pulling the tail line — attended use only, with the tail kept reachable and untangled.
- Securing an aircraft during loading, then freeing it remotely once loading is complete — not a substitute for a proper tie-down during the loading period itself.
Boating and Docking
- Temporary small-boat mooring with a remote release for a solo launch or departure — attended, short holds in light conditions only; never under real tension or in high wind without a backup.

Notable Features
- Total Remote Release: The rig releases entirely with one sharp tug on the tail line from a remote position — cockpit, dock, or a safe standing distance.
- No Return Trip: There is no need to go back to the knot to untie it, which is the whole point for a solo operator.
- Sudden Disengagement: Useful in situations that call for freeing a craft completely and instantly, such as a one-person launch.
Similar Knots
Highwayman's Hitch vs. Exploding Release Knot
Across aviation and marine sources alike, the Highwayman's quick-release hitch is the most commonly cited real-world "exploding type" knot doing this same one-pull-release job. It comes with a well-documented caveat: in the IGKT's quick release knots discussion, Dan Lehman notes that a heavy load lands directly on its toggle bight, which can collapse and pull through instead of releasing cleanly.
- Advantage: Far better documented, widely taught, and proven for the same one-pull-release job.
- Disadvantage: Heavy loads bear on its release toggle, a known weak point for clean release.
Exploding Clove Hitch vs. Exploding Release Knot
The exploding form of the Clove Hitch is a sibling from the same family, built on a known base knot with a fully documented structure.
- Advantage: A confirmed, step-by-step documented structure on a familiar base knot.
- Disadvantage: Tied at the anchor rather than rigged for release from a remote position.
Two more relatives in the same quick-release family are the Long Release Hitch and the Exploding High Point Hitch.
Security Level
Low, by design. This rig is not load-safe: it should not be used under tension or in high wind without a backup, and never for high-risk mooring where a premature release would cause damage. The same light-pull sensitivity that makes remote release possible means a snag on the tail line can release it by accident — so it is a hold for attended, temporary, light-condition use only.
Downsides
- Accidental Release: A snag or unintended pull on the tail line can release the whole rig unintentionally.
- Not Load-Safe: It should not be used under tension or in high wind without a backup.
- Tail Discipline Required: The tail line must stay accessible and untangled along its whole run, or the rig either fails to release or releases when you don't want it to.
Structure
This is best understood as a release technique rather than a single fixed knot shape: a line is secured with a slipped, nipping hold, and one free tail is routed back to the operator so that a single pull collapses the entire hold at once. Bear Essentials' rule for exploding knots: a rig built to release on the lightest deliberate pull can never refuse an accidental one — if you need a hold to survive unattended, you need a different knot, not a backed-up exploding one.
History
The "exploding" name traces to Peter Suber's 1997 essay Six Exploding Knots, which coined the term for knots that untie completely, tangle-free, with one tug of a ripcord. The exact problem this knot addresses — holding an aircraft so a lone pilot can release it remotely — was worked through by real practitioners in a 2012 International Guild of Knot Tyers forum thread, years before this knot got its name. The specific name "Exploding Release Knot" appears in no knot book or database Bear Essentials has searched; it joins Suber's terminology to that genuine aviation use case, and the name itself originates with the Knot IQ app.
How to Tie the Exploding Release Knot
The steps below describe the rig at the technique level — how the release is set up and used. To see the exact tie in motion, the Knot IQ app walks the rig through step by step — the clearest way to learn a release whose whole job depends on how the tail is routed.
Step 1
Secure the anchored object — aircraft or boat — with a slipped, nipping hold, leaving a single free tail routed clear back to the operator's position: cockpit, dock, or a safe standing distance.
Step 2
Confirm the tail is untangled and free of snag points along its full run before relying on the rig.
Step 3
To release, pull the tail sharply from the remote position — the hold collapses and the object is freed instantly, with no need to return to the knot.
FAQ
Is the Exploding Release Knot safe to use under load or in high wind?
No — it should not be used under tension or in high wind without a backup, and never for high-risk mooring where a premature release would cause damage.
Can this knot release itself by accident?
Yes — a snag or accidental pull on the release tail can release it unintentionally, which is the tradeoff for being able to release it instantly on purpose.
Important Notes on Safety
This rig is not load-safe: do not use it under tension or in high wind without a backup, and never for high-risk mooring where a premature release would cause damage. It can release unintentionally if the tail is snagged or pulled — the same single-pull sensitivity that makes remote release possible makes accidental release a documented risk of this design class. Keep the tail line accessible, untangled, and clear of wind, prop wash, and foot traffic, and only use the rig for attended, temporary holds.
