hawser bowline, extra step winding the collar legs on

is this feasible, or nay.

here the working end will double up, and be winched onto the s.part, i think; forms u-turns, or an s-shape?

the third example might need a bit of babysitting while tying it, but fun to watch if nothing else :slightly_smiling_face:

can’t see it (or bends) in the Ashley book, but it could be obscure?

… i have been taking a closer look at bowlines, influenced by the forum chats ! and learning from the clear text and illustrations from PACI thanks agent_smith

4mm poly cord cover

3mm dyneema, an brief ball-park test on car jack to see what happens. the markings on the tails each started out at 15mm from their exit, (hand tightened maybe 15kg) and have moved about 8mm and 3mm, but i don’t know what the weight on the jack was. possibly 40kg.

Hello Alana

Very good demonstration and analysis including also video with quite observable tying techniques.

I’m looking into your second marlin spike-like configuration, and starting with good news first, i maintain that, the knot is stable, secure with a rock solid core in its final energy stable state and it is generally a fine method to stabilise a crossing knot.

However, i see that you are using a small diameter, relatively soft rope, and with only hand tightening (cinching), your core is subjected to some modifications that alternate its initial form, until the energy stable point is reached.

This very state shown in your illustration, looks like a blop of ropes, with no actual access point to interact with after being subjected to a serious level of loading (more than 40 kg).

A folded bight structure and also severely compressed by SP, impedes the loosening process to a serious extent.

Try to imagine the state of this core with a stiffer large diameter static rope, in heavy stress conditions.The loosening situation could be achieved only with the use of the right tool, such as a hammer.

That’s also the reason that i do not dare delving into your third configuration, because more complexity in the nipping component, would be no less than a very stiff and hardly manageable core.

In my opinion, it would be great only for light weight.

Very smart, marlin spike manipulation tying techniques, i’ll give you that.

I believe these structures are not well documented, the closest thing i have seen is the following Alan Lee’s marlin spike loop, where the returning structure is actually a loop and not a bight.Maybe the loop is a more effective returning binder with less distortion?Can’t be 100% sure.

Glad to see you exploring bowlines :smiling_face_with_sunglasses: .

Another video of the original creator Alan Lee testing his marlin spike loop with a small diameter soft rope up to destruction!Easy loosening with this type of rope.

Glad to see you exploring bowlines :smiling_face_with_sunglasses:

it’s contagious!

thanks Kost_Greg for assessing these knot forms and detailed commentary!; and, they aren’t bowlines anymore?

I’m very glad to know the good news first, that the marlin spike-like knot passes as stable.

and then the bad news that they are prone to blop, especially demo knot #3, under heavy stress … i could see what was happening, and you were able to word it

with no actual access point to interact with

i’ve learnt much! thanks for (digging up) the Knotting Knots’ video and Alan’s video, great. i wouldn’t know how to find such, as it’s difficult to search for something when you don’t know the name of what you’re looking for - that’s why i ask here :slightly_smiling_face:

The components that form your core, suggest by definition, that they are quasi-bowlines, with a TIB nipping structure equivalent to unknot, hitched with a returning bight structure, but i have a hard time supporting their bowline qualification within the broader sense of the bowline concept, as we have conceived it.

Yet, the interaction is quite important and might point to other directions.

For instance, if i apply your brilliant marlin spike method, as shown in the following image, with the loop placed under the SP this time from the other side, as indicated by the white arrow, another configuration is formed,

which is subsequently WE hitched in hawser-like and marlinspike fashion ,

Now if you load the above structure and perform a slight maneuver such as a collar flip, you get a more conventional bowline, which i think Dan Lehman would appreciate :smiling_face_with_sunglasses: (EBSCB).

oh, that is a great tweak, the tail to the inside; i had tied it and missed recognising it as aesthetic - but it is! i had just gone along with the direction that the W.E naturally went (least resistance). but it appears that the tail to the inside resembles the usual bowline, and is more secure than before?; because the (..consults PACI diagram..) entry leg is sitting on the exit leg and clamping it down in a tidy manner.

the way you’ve tied it with the SPart ‘segment behind’ brought through and folded to the right, makes the knot form up and balance itself out in an intriguing way. it’s a beauty. i will stare some more at it. so different from if the tail is tied to go outside. also, notice that if the tail is pulled out by one tuck, it becomes a cowboy bowline (of your knot, both: tail to the inside, and tail to the outside).

quasi-bowlines

=) happy to have it in a category now.

having a re-tie of my quasi-bowline, but with the WE coaxed to sit inside the eye, it is an instant improvement :blush:. there are piles of variants, and good to find the picks. photo: i just posed the WE behind itself to hold it there for the photo. all it wants to do is move to the outside. arrow points at snug-looking contact? (good)

reminds me of Xarax’s Bingo bend, with shapes in it that he called ‘hooks’
