Some of you may know that that the Constrictor and the Double Constrictor can be tied on a bight (middle of a rope without access to the ends). So can the Boom! How do I know the Boom can be tied on a bight? Well, if I slide a Boom off the end of a pole, the whole thing comes completely undone by merely pulling the ends. I just have not yet figured out how to reverse the process.
I challenge someone to tie a Boom on a Bight. Pics may be asking for too much, but if it’s not too much trouble, then please do.
I had a feeling I was getting into trouble, here. mea culpa! :-\
Well, note that the next-to-rightmost turn can be moved out
around the rightmost & off the right end, and reduced to
a turn at the 2nd-from-left turn’s crossing point (i.e., reduce
down the freed turn back into rope still surrounding the
object, mentally);
now you can see that the rightmost turn can be removed,
and then the turns from the upper end unturned.
Reversing this,
one would make those turns from the upper end,
then form the turn/half-hitch-like of the lower end
and put it on,
then draw out sufficient material at that 2nd-from-left
crossing point to create the to-become-2nd-from-right turn
and move it out rightwards , around, into position
–which doesn’t have to be all so far “out” if just forming
the knot, or working at the end of the bound object.
What is not so desirable with this boom hitch is the
departure of the ends --i.e., their relative angles off
of the object (if to be jointly loaded), and the difficulty
of setting tight --which takes working.
Is this boom supported on something other than lines? Maybe you have access to the end of your boom but all mine have a topping lift or a quarter lift pair attached at one end, a goose-neck or other attachment to the mast or spar at the other end and a sail attached atop the boom in between the ends (or, if it is a gaff, then below the spar - but then that is a gaff and not a boom) - where exactly is this boom of which you are making a boom lift? Perhaps this is not really a boom but some sort of pole? I, of course, am being somewhat literal here looking at this being an actual boom. What have I been missing?
You may be misunderstanding. The challenge here is to tie a Boom on a Bight (in the middle of the rope without using the rope ends). Once the Boom is formed, the object is placed through the Boom and the Boom is tightened. An analogy is tying a Constrictor on a Bight like this:
My usual use for a Boom is for attaching rope to a flashlight, a wrench, an extension cord, a pill capsule or other item that does not have a convenient way to connect the rope (which is usually a bootlace). Wherever a Double Constrictor may be tied, that’s where I often tie a Boom instead. A Boom works well on circular items, but is certainly not limited thereto.
Imagine a sling with no access to the ends, and imagine I want to tie a flashlight to the sling by using a Boom. I have two options: I can disassemble the sling and tie the Boom normally, or I can tie a Boom on a Bight. Like any other knot, a Boom does take practice to dress correctly, but I believe the trouble is worth it.
However, this thread is not for discussing whether or not the Boom sucks for the applications I listed here. I’ve already determined, with my own hands and rope, that the Boom works well for my purposes. This thread is for figuring out how to tie a Boom on a Bight. 8)
Okay - the Boom is not but the challenge still stands - try the attached…
The instructions read:
Start with the cord leading over your fingers from top to bottom, bring the cord up behind your hand and trap it behind the first part to make a clockwise underhand loop (half hitch) over your hand.
Form a second half hitch, but now make it counterclockwise
Bring the standing part up over the back of your hand and cross over the working end
Form a bight with the standing end
Tuck the bight up through the second half hitch
Twisting the bight toward you make a second counterclockwise underhand loop
Slip the loop over your fingers, fair it and ?boom? ? it?s done!
Pics! That’s what I needed! I will try it out, thanks.
EDIT: OK, I did it. The first two pics and your written description helped. I can only understand pics 1, 2 and 6. Pics 3, 4 and 5 are confusing. Now that I get it, I can look at the pic in the original post and figure it out from that.
