awesomeforsale.com/ The bowline has a couple key features that make it effective. Here I use some of those features to create a new knot. At least new to me.
@zchuss1 so "the bowline" isn't the greatest... but the "yosemite finish bowline" or "the water bowline" or "the double bowline" is the greatest? if it is a variant of a type of knot, then it is still that type of knot.
0:26 The bowline knot is thought to have been first mentioned in John Smith's 1627 work A Sea Grammar under the name Boling knot. Smith considered the knot to be strong and secure, saying, "The Boling knot is also so firmly made and fastened by the bridles into the cringles of the sails, they will break, or the sail split before it will slip." Another possible finding was discovered on the rigging of the Ancient Egyptian Pharaoh Khufu's solar ship during an excavation in 1954.
This feels like a prequel to a video talking about how knots reduce the strength of cord and why. I'm paused just before the tie breaker. My intuition is that the strength loss of a knot is a factor of bend radiuses. The bowline has the turn wrapping around two cord thicknesses, and the bite wrapping around 1. These operate in tandum so the ultimate strength loss of them together should be between them, and I think leaning more towards the strength of the turn because it's relieving some of the weight the bite would bear. The test knot has a turn around a single cord thickness, and 3x turns around two cord thicknesses, which are sharing the load. The 3x turns gives more total length at 2 thicknesses, and 1x turn is on 1 thickness so it's weaker than the bowline's equivalent. More compromised-length should yield more, but I don't think that would make it more likely to fail; more-compromised length should yield more over the same length, which does mean it's more likely to fail. I think the test knot should be weaker -- but there's a lot of factors here. *click play* I'm seeing the test knot yield more, and that's allowing it to spill, now it's not holding tension in the way described. Now it's trying to pull the barrel apart perpendicular to the coils, but the single turn has converted into a tensioning mechanism that converts this spreading force into tightening the barrel so the bite can't pull through. Now the radius in question is the loaded lines bending around the mouth of the barrel, ~90 degrees each, and that's equivalent to the bowline's bite... Once the test knot spilled, I think it became equivalent to the bowline in terms of strength loss... via this analysis anyway...
The weak point of your knot is the same as the bowline: it's not under tension, but coming apart or slipping when there is a lack of tension or a repetitive push-pull. After all, that's why the bowline isn't used in sailing neither for anchoring nor docking, and never used in climbing (climbers invented several "safe" variants of the bowline e.g. Yosemite bowline). A better loop knot, if not the better knot ever, is the "zeppelin" bend, but used to tie a loop. But it's not as easy to tie as the bowline, and because we don't have access to both free ends, it's also trickier than the base zeppelin bend itself. It would be awesome if you "reverse-engineered" the zeppelin knot the way you did here to solve those problems!
I'm not sure what sailer doesn't use bowlines including myself for most tasks. Climbers use the end bound single bowline and the easiest stable bowline is the Scott's locked bowline. PACI recommends about 5 bowlines that are stable and locked down. I highly recommend reading their paper on the good ones. Nothing wrong with the zeppelin though.
bowlines are used all over the place in my experience in docking and anchoring. it’s important to load them first. and if you’re nervous you can throw two half hitches in but i never really knew how much that really helps. and then you can yes go for a better knot. never had a problem, never seen a problem with a proper bowline that’s been loaded a bit for anchoring or for docking.
Bowlines are simple to untie and quite good. The Scott's locked bowline variation makes it very secure, yet easy to untie. I found this interesting but will stick with the bowline.
@@paddor Scott's is very easy to check and very easy to untie. It is very secure. The bowline is a knot, it is not intended to be permanent, for that, use an eye splice. Experienced climbers find it as secure as a double figure-8 but much easier to untie.
@@tanguerochasthere's a guy on UA-cam who's partnered up with how knot to channel and he's found a way to make a figure 8 that loosens after being loaded... Really awesome video..
I have a knot I have used for years you can test, I use it for attaching things to my work and camping bag, no idea if it's been invented or used before I have never checked...its very similar as to how you do you adjustable loop but mine will complete spill when released...I do not have the rope spare to be breaking it on the lorry as it's already spliced to hell. Having watched the video I observed the knot twisting, try adding a 360 twist and throwing it over the slipped loop, this should stop the slack being pulled out and stop the knot from twisting....and this is one I will try with a pallet drag as that stutters and really tests a knot stability. I think if this works in heavy rope it may be my go to knot for pallet lashings and ridgline.
Great video! Thanks for taking the time to explain why the knot is tied the way it is. I feel like your brain sees the world differently than me, I understand quite a few structural and mechanical things BUT, topologies or whatever the science of ropes is called breaks my brain.
The ReLoop works great on small diameter poles or hooks, but if wrapped around larger diameter poles the ReLoop works itself loose and does not hold. Try it and see. Maybe I’m tying it wrong. Thanks for this new knot.
Also it is probably better suited for a more static even application. In the slow motion you can see it moving around wanting to untwist. So in a real world situation getting jerked, bumped, jostled, rubbing across something, it would probably be more likely to get enough slack or get knocked back through the loop and untwist and fail.
would tying the end to the line being pulled, just a little half itch or something, to redirect the direction the rope/know lays on itself, reduce the affect of the rope sawing on itself?
Never load a bowline from anything other than the standing part. If you load it on the loop, using it as a binding, it can capsize into a slip knot with a poor grasp of the bitter end and zero reliability.
Why oh why do people insist on tieing a bowline with the bitter end sticking directly inside the working loop.l!? Why! It's asinine to willingly place the tail inside the work zone, when all you need to do travel around the main line the opposite direction on the end tie off, and the tail will spill to the outside of the entire knot. But no inside the work zone for everyone!
To minimize the risk of having it snag on to something. Important for maritime use, that's why Ashley recommend against putting it on the outside. Tied the other way it is often called a cowboy bowline
This whole video just proved to me how genius the bowline knot is.
Bowline always fails in my job because of the stuttering of weight....if I have to use it I finish it with a yesomite.
@@zchuss1 Still a bowline. A Corvette with a supercharger is still a Corvette, no?
@@GlueChickeN10 I would argue that if a knot has to be altered in order to fulfill its purpose, maybe it's not as good as it claims.
@zchuss1 so "the bowline" isn't the greatest... but the "yosemite finish bowline" or "the water bowline" or "the double bowline" is the greatest? if it is a variant of a type of knot, then it is still that type of knot.
@@stevenpannozzi9151 ok let's use logic here.... If the bowline is the greatest loop knot in the world..... Why are there others.
I greatly appreciate that you show your experiments whether they succeed or fail.
Awesome, extremely quick to tie. I like the way you test the knots for reliability. Thanks for your continuous innovation, Brent!
Thanks Flynn
Part of the benefit of using a bowline is someone can look at it and go "that's a bowline" interesting video again thanks.
Another way to think about the bowline, is just a sheet bend built on itself! Love them both
Gosh your rope tying is incredible. I wish to remember all of these like you do
What are your other two wishes?
@@1neAdam12 wish 2... ten more genie-inhabited lamps; wish 3... set the original genie free (no point re-imprisoning it)
Very romantic. Both knots held tight to each other even after their ropes were gone.
I’d love to see more theory videos
It may seem like a simple thing, but having two colors on each side was maybe the most helpful thing about this video vs everyone else's.
You are SUCH A GEEK and I love it 🥰
I really liked the tensile tests. Please make more videos like this. Thanks.
The last test “was a tie” 😂 an unintended pun! 🤣

"it's a tie" -- I see what you did there 🤣
Great stuff, thank you! Random: I just did a quick test of this with dyneema, figuring it would surely slip, but it actually worked.
Great!. Thank you for sharing...

I was trained to tie that Knot differently, where the lead end is routed to the outside of the loop, not the inside, as shown in this tutorial.
I have a knot I have used for years you can test, I use it for attaching things to my work and camping bag, no idea if it's been invented or used before I have never checked...its very similar as to how you do you adjustable loop but mine will complete spill when released...I do not have the rope spare to be breaking it on the lorry as it's already spliced to hell.

Please do a video on inuit or kalmyk knot. Mongolians use it. Most used knot in Mongolia
Amazing!
A bowline is a sheet bend tied in one piece of rope, which gives the loop.
Do you think adding a second turn to the constrictor loop to distribute the friction across a wider area of the rope would help?
Great video! Thanks for taking the time to explain why the knot is tied the way it is. I feel like your brain sees the world differently than me, I understand quite a few structural and mechanical things BUT, topologies or whatever the science of ropes is called breaks my brain.

"It's a tie." ...Oh you so funny.
How would you compare it to using a Slipped Sheet Bend (by tying to itself) to create a loop?
Wasn't the bowline found on an ancient Egyptian ship that was found? I heard that on the internet so I KNOW it's true, 😂. Cool video,
would tying the end to the line being pulled, just a little half itch or something, to redirect the direction the rope/know lays on itself, reduce the affect of the rope sawing on itself?
The bowline is basically a sheet bend with a loop.
I think the first verified bowline was found as part of the kufu ship buried at the base of the great pyramid
Ancient Egyptian boats in the valley of the kings
Double the loop on the bowline, much stronger.
Two knots in a shootout
…
It’s a tie 😂
What if you added more counterclockwise turns? Will it make the knot stronger?
4 minutes you almost had a bank robbers hitch
If you’re looking for requests, could you make a sheath for the marlinspike?
I’d bet the oldest bowline ever found was on Ötzi the Iceman.
How does this compare with a kalmyk loop?
What are you calling this knot
👍🏻🇨🇦
It's looking like you're elongating a round profile, like you mentioned in another video, by looping twice.
Can this knot be quick-released? It looks like it might work by pulling on the end of the rope
I just tried it and assuming you can pull the slip out (there's 3 round turns holding onto it!), then yes the whole thing will come undone.
That's the point of feeding a bite through a loop at the end. In almost any knot, end it with a bite and you get a quick release.
Egypt.
Never load a bowline from anything other than the standing part. If you load it on the loop, using it as a binding, it can capsize into a slip knot with a poor grasp of the bitter end and zero reliability.
Why is it that the only thing anyone talks about is strength. If you are worried about strength alone you need to rethink your entire rig.
If you put a stopper knot on either knot it ain’t going anywhere
The bowling just like most everything began in africa. They discovered the 1st bowl and not on one of the. Egyptian pharaohs boats.

An imbalance of leg load will cause problems. There are simpler solutions.

Yep, that's how I was taught. Tied it that way 1000's of times in my career, each year.
