I have been handling 1.75 Spectra /Dyneema throwline for tie-outs for a little while. There are other throwlines of Dacron / Polyester and polyprop. I thought this would be a thread for some comments and tips on any / all of them.
Here is copied WV's response to an off brand throw line,"Chuck-It".
Not quite what we thought, but still good
Received my Chuck-it from Demostix today and set out to see how it compares to Zing-it for splicing. I used three different splicing tools, a loop turner, a piece of CAT-5 network wire, and a Cortland "No-Knot Tool". I expected to have difficulty with the loop turner, as it's a struggle to splice 1.75mm Zing-it with it. In fact, all three worked, but the loop turner made me struggle, as expected.
The surprise came when I went to taper the end before burying it. It was easy to pull out separate strands and cut them off, but in doing so I saw the outer sheath slide back, revealing a central core of parallel strands. I'm surprised that I was able to slide the splicing tools down the center, considering the line is not really hollow core. It's easy to miss. On a subsequent splice the core didn't reveal itself at all.
I'm not a fan of kernmantle construction, but I think this line will serve well as an economical alternative to Zing-it. WV
The maker includes these notes, which may be applicable to all throw lines, especially as regards tangling of 100+ ft lengths.
It is recommended that a throw line be broken in , and laid completely out and hand tended into a pile, and then repeat the operation, be careful to remove any twists and turns present. The trow line should then be hand flaked ....for initial use, making shure not to impart twist when flaking into the bag. It will be worth spending extr time to flake the line carefully before throwing or shooting. This should allow a tangle free working tool every time
I'm breaking in yellow-green fluorescent Chuck-It throw line radically by running new stuff from the hank or reel over the back of a knife a few times. This breaks the wax coating. It is much less stiff after doing this.
I attach it for tie-outs with bowline knots. Not so elegant as within an eye splice. I'll sacrifice some breaking strength with 450lb bs available.
Chuck-It is not as bright as Glowire. Be AM coffee, eye rest, or sleep I like the greater visibility in dim daylight of dawn / dusk. Glad I replaced 2mm braided gray-giveaway- polyester for that reason.
I have not tried yet to find out if it gives away stealth, by being so bright at great distance.
Other tips on this or other throw-line for tie outs?
For other repurposes?
Tips on ridgeline use. eg prussics?
