About the tugboat Scott’s locked variation, yes it is very secure with a super easy tying method, but as i mentioned previously, i’m not so sure about its ease of untying, even with loads, so much as 6 or 7 times X bodyweight.
You see, it’s like loading Scott’s knot from its most complex component, the returning structure, adding 50% additional strain, which at some point will definitely induce jamming.
When i see a profile like your SymmetricalScott, with so neatly organised, very easily inspected components, i usually have great expectations about its functionality.
The same stands for the knot at reply#16, which is a combination of two good techniques in nipping loop stabilization, EBSB, and simple lock.
I’m not sure about the use of the bight collar encircling the returning line, but i don’t feel like fiddling with it and ruin the symmetry of the knot.
The only thing that concerns me, is the squeezing conditions inside the nipping loop, caused by the end bound (or myrtle) turns as they hold very tight the nipping loop’s crossing point.
Not exactly the best part of the knot to interact with, after heavy loading, compared to a U fold is it?
Hopefully, the pliability of a bowline-like loop is not being compromised in such a good and very compact knot.
Excellent, way of synthesizing the components!
