Building bowlinesque, double loop, anchor systems
« on: April 25, 2023, 02:51:40 PM »
This is a very easy and yet effective way, to build a double eye knot for anchoring, towing, e.t.c.

It can be done by combining a bowline and an anti-bowline, side by side together using one nipping loop with four rope diameters inside it.

One can start with a simple cowboy bowline, leaving a long tail component in order to create the second eye, and nip the returning tail in an anti-bowline fashion.

There are many other ways to restrain the returning line into the nipping loop, like ampersand, fontus or triskel, and they all form a super strong,resistant to cycling loading, dual loop, knot, with very easy system equalization through the bowline collar.

It is not TIB (tiable in the bight) of course and only OEL, (one end loadable), but i'm sure there can be other profiles with those extra properties.

New ideas in this concept are welcome.

When it comes to TIB, EEL, double splayed loops, bowline-like structures, i could not fail to mention the depicted Karash variation, which i find very stable to flogging forces, even more than a butterfly derivative.

The secondary loop's complexity has been decreased by one unit/order, without having any effect on the overall stability of the whole structure, compared to the conventional Karash configuration with the two equivalent link components.

If one removes whichever of the two links, there will always be a bowline.

Starting with a simple Karash bowline, in cowboy style, the long tail is tucked under SP, capturing both collar legs for the nipping loop formation, and follows the SPart, side by side down through the collar.

I don't have a TIB method yet, but i presume that the knot points to an inline profile , interweaved with overhand and figure eight components.

Another double loop variation, that builds a second bowline around a fixed point, using a long tail component.

The secondary eye, is usually tied with a retraced bight, which is tucked back through the two collars, in a yosemite tie off.

Since this method adds plenty of bulkiness in the system, i was thinking about a simpler and easier way to lock down the tail, staying as bowlinesque as possible, such as the Scott's locked technique.

It's not only that it adds 5 rope diameter inside the nipping loop, it is also TIB, with a super easy in the bight, TIB tying method.

It's an easy task to figure it out, if the knot is reverse engineered.
