Undoing a hitch from 100 feet away

[macbeth]

Is there a reliable knot or some other way of doing this ? Basically, I want to drag articles to a block that's 100 feet away from me at the far end, using continuous rope, back and forth, and then with out moving from where I am, pull a control rope, or some other device, that will undo the hitch.

You can set up something like this:

Tie a cord to the toggle (a marlinspike is sometimes used for a toggle), then give it a tug when you want it to disconnect.

Another way is to use a snap shackle and a tether on the release trigger.

If i understand, you have a "clothesline" made of two blocks and you want to tie something to it at your end then wheel it out 100 foot and drop it. Correct. how heavy is object? if it is lighter you could just use a slip knot and a 100 plus feet of rope.

As shown here: Slip Knot | How to tie the Slip Knot | Basics Knots

But the short tail here would be your long end. Hopefully you don't pull it apart getting it to the other end.

Perhaps a better description of your goal will help to get you the right knot.

Go to your local library and take a look at Ashleys book of Knots (probably in the reference section) he has most knots and cordage solutions. A classic book.

Or just a snatch block?

Thanks for responses. Enough to give me ideas. End of thread from my perspective.
