Also check out ABOK #1727, #1994, & 2073 - all the same knot and the one I'd been calling a backward/upside down tautline hitch. Ashley calls it a Jam Hitch, Adjustable Jam Hitch, and the "opposite of the Midshipman's Hitch." A bit bulkier than a buntline but adjusts and holds.
This has been a long issue that I keep mentioning, but nobody has responded. For a
mid-air binder, you have been suggesting tie a backward Tautline (ABOK #1727). However, I have been tying a regular Tautline as a binder, except the Tautline is sliding in the opposite direction making the loop smaller. I can crank down on the tension because in order to tighten I pull the standing end in the opposite direction of the working end. In other words, I have more leverage. The final Half Hitch in the Tautline binder is held tight by the force of the coil, and the knot thereby remains secure. In fact, it's so secure that it really needs a slip in order to untie things. Again, I'm talking about a
mid-air binder.
Do I need to provide a pic?
