Knots safe to tie into HH suspension

[peterhase]

I use a trucker's hitch and it works well. Fast to tie up and pull down. I tie in different parts of the suspension ropes every time, so I can't imagine it wearing out any time soon. Something else will break before the suspensions ropes do

Up until a few months ago, I used the standard figure 8 lashing that Hennessey recommends, but found that it was a real PITA to get tightened. Recently, I've taken to using a lark's head to attach a descender ring into the stock line a short distance from the hammock. I then run the rope through the webbing, back to the ring and tie off with a trucker's hitch. It is soooo much easier to set and adjust. I've made some whoopie slings that I'm planning on putting on (possibly this weekend), but this set-up works really well, too.

The reason for the lashing is that most knots tend do jam after an all night hang. The lashing does not do that because all the turns over each other decrease the load at the actual pinch point. If you use a simple bow knot it will hold without damaging the rope or letting you down but you can have a very hard time untying it. If you want ideas look at any of the knots used for tying monofilament line to fishing tackle and make it slippery by passing a bight instead of the bitter end through the pinch point. All the one's I have seen use multiple rope passes to lessen the tension at the pinch.

You do not need to hang the Hennessy twang tight. The ideal is to have the ridge line under light tension when you are hanging in it. Anything more is just stressing the system for no reason. The length of the ridge line establishes the sag in the hammock so once it has tension it is working.

FWIW the Hennessy rope is not amsteel and does not have the same problems amsteel does in knots.

Well, sort of. You do want to avoid tight knots and knots around very small hardware with amsteel. I've read that there is some number of times the diameter of the amsteel you want hardware to be (I think it's 4, but don't quote me on that), and the less tight the bends in the particular knot are, the better.

Yep its called D/d or diameter to diameter ratio. Basically the tighter the turn that a rope, cable or sling had too make around a point the more it reduces the WLL (working load limit) of the rope. It's usually 5:1 for synthetics materials but specialty materials can be stronger or weaker. Here's a site that explains it pretty well.

You can try a marlin spike hitch-- if it holds then after hanging all you gotta do is remove toggle and the hitch is gone. Use a toggle that is smooth so it won't pick your rope when removing toggle. Sometimes I put extra wraps in marlin spike hitch

[trekkingnut]

marlin spike hitch is a good choice

I do this but with the figure 8 lashing:



There is a prusik loop on each end on the ridgeline that I use to adjust before tying in the figure 8's.

Each to undo just open carabiner and slide figure 8's off.

Hope this helps.

I've tied a triple fisherman's bend knot in my hennessey suspension, just because I trust that knot completely and have used it for other hammocks. I'll never get it untied of course, but don't plan on needing to

[Phantom Grappler]

You want the best knot for the task. If you have a choice between two or more knots that hold about the same--I choose knots that are tied in the bight and quick release. A knot that is tied in the bight( without having access to either end ) can be tied faster especially if there is excess rope. And quick release is faster to untie--I add half hitch to bight in quick release knots to "lock " them against accidental release. And you want knots that are jam resistant. Good luck.

Expedition Asym of mine gets two descender rings.I use a Dutchable clip,JRB Triglide,and/or climbing rated carabiner in the mix depending on how far the straps need to extend.
