Most secure "slip" knot?

There are various knots that can be undone/"slipped" by pulling on the loose tail.

My question is which of these is most secure? Which will hold best with a jerky high load?

Re: Most secure "slip" knot?

I often use a clove hitch with a slip on many things and never had it jerk loose with load. Also use a slipped taught line hitch too for adjustable stuff like canvas.

A lot probably depends on the type and size of line used, though.

I use a taught line or for my best work a hangman noose.

Re: Most secure "slip" knot?

I may be using the wrong termonology. I do not mean a slipping loop. I mean something that when I tug on the end it will Untie itself.

Re: Most secure "slip" knot?

I understood you that way. The slipped taught line still has a half-hitch to undo after tugging the end, but for that knot, the half-hitch is usually not tight against anything so it is easy to undo. The clove hitch is often around a piling, so this usually requires manually lifting off the loops due to friction.

Bight on a bight? Slippery Zepp?

Most secure knot for what purpose?

Re: Most secure "slip" knot?

From the context I assume you mean a slip knot to fasten the end of a line to something like around a piling and not tying to ends of a line together like a line around a furled sail on the boom.

For the former, not a completely slipped knot but very secure I tie one half hitch and a second slipped half hitch. Pull the tail and the second half hitch drops away but you have to pull the tail through to untie the first one.

For the later, a single slipped reef knot.

That is what I do too.

I also use this when a full taut line hitch is unnecessary. If there is load on two half hitches, particularly jerky loads, then they tend to slide down the line until tight against what you secured around. This makes it difficult to pull the tail through the first half hitch when undoing. The taut line generally doesn't slip like that.

I always tie two half hitches tight against what I secure it around. I use taunt line hitch too, just not nearly as often. About the only times I can think of are when putting up the sun-shade and clearing a winch override.

This works for me unless I think I need something more "secure" to which I would add a couple of round turns prior to the hitches.

But I think undoing this is probably more complicated than what you're looking for.

Maybe a buntline hitch with a slip hitch at the end would serve you better?

I like the highwayman's hitch: http://www.animatedknots.com/highwaymans/
It works well to avoid snagging a bitter end when leaving a dock singlehanded.

Re: Most secure "slip" knot?

I use a knot to tie up my horse to the fence but have no clue what the name is. It won't come loose if he pulls back on it but if he panics all I have to do is pull on the open end and it lets loose but I still have a hold of him with the rope. I know it has a name....just don't remember it.

Found it....it's the mooring hitch....at the same website as above.

I had forgotten about the Highwayman's knot. Hadn't thought about it in years. I like it.

Grog seems to think the Tumble Hitch is the best of the bunch, but still not to be trusted without supervision.
