Rigging a No-sag Hennessy Hammock Tarp

Rigging a No-sag Hennessy Hammock Tarp

My first camping hammock was theHennessy Expedition Asym. It was the hammock that converted me to staying off the ground when I went camping. However, I was often frustrated that I couldn’t keep the stock tarp taut, particularly when I got in the hammock. I could make everything look amazing and beautiful on the outside, but once I got inside, the hammock settled and the tarp went slack. Limp. Frumpy.


My solution at the time was to remove the tarp from the hammock and pitch itseparatefrom the hammock, but there are still a few advantage to having the tarp connected to the hammock suspension:

  • Easier set up and take-down (especially when using a sleeve or SnakeSkin style stuff sack)
  • 没有吊床和tarp悬架之间的冲突
  • The tarp is always centered over the hammock
  • 没有磨损树皮上的篷布线
  • Lighter (ounces to grams)

将篷布连接到吊床悬架不限于轩尼诗吊床模型。你可以在篷布上钉anyhammock so long as the suspension extends long enough to provide a connection point. For example, you can connect a tarp to whoopie slings using a prusik knot on the non-moving side of the adjustable loop.


The ‘trick’ to rigging a no-sag Hennessy Hammock tarp—to keep the tarp taut even when the hammock is loaded—is all in how you hang the hammock. Traditionally, the Hennessy is shown being pitched very tight across the anchor points. However, the tighter you pitch the hammock, the higher the horizontal “pulling” forces, which in turn, stretch the suspension components more. That stretch lengthens the suspension (a lot or a little), which changes the hypotenuse and the point where the tarp用过的成为,从而使其松弛。




tarp连接点还可以进一步安排up the hammock suspension, which keeps the tarp taut when the hammock is loaded.


But, don’t take my word for it—give it a try and tell me what you think.

    YES!!! Thank you.

  2. Coy Starnes says:

    谢谢德里克,我一直挂着我的轩妮尼宽松,但你提到的那样松动。主要是因为它对悬浮液的压力较低。我将在下一个挂起上使用此方法。现在我唯一的问题正在寻找一些轻量级的油漆罐,我将被设置... .jk

        How does increasing the angle to 30 degrees affect the diagonal lie. It would seem to be more banana like and less flat.

        • 你需要一个美好的一天,所以你可以铺设对角线。当你对角地穿过织物的偏见时,你遵守符合人体工程学的。当你尝试挂吊篮时,你就陷入了茧和过度伸展的膝盖和脚踝的茧中。

  3. 丰富 says:

    If I was using a daisy chain tree strap (I have the python straps), wouldn’t I just be able to clip in the hammock on a rung above the one I have hammock clipped into?

    • Derek says:


      You can estimate this angle by using your hand–extend your thumb upwards to the sky and point your index finger toward your hammock. With a little weight in the hammock you can measure more accurately, but you are trying to line up the suspension by touching the tip of your thumb and the tip of your index finger to the suspension while keeping your index finger horizontal and pointing to the hammock.

      Boy, that was easier to draw or demonstrate than to type

      You can use my hammock hang calculator to estimate the anchor point but for an average distance of 15 feet, you’ll need to attach your webbing about 6 feet high.

      If you hang lower than that and just try to clip in to a loop closer to the tree but further up the daisy chain you’ll only tighten the suspension. You actually want to loosen it in a manner if speaking.

      Let me know if that makes sense.

    I don’t have a HH just the old ENO and a kelty noah`s tarp. But I tried this out this afternoon. It worked great! Thanks for the best ideas!

    • Derek says:

      Tim, it should work but we might be missing a detail. Give me your specs and I’ll try to work it with you. How far apart are your anchor points? Are you using a Hennessy? How big is the hammock and how long is the hammock ridge line?

    • Derek says:

      Okay, I’m doing a little test here.

    • Michael Johnson says:

      I have the same problem with my deep jungle asym zip: When the hammock is hung at a 30⁰ angle (measured with a protractor), the ridge line drops into my face and the bug net is useless.



  6. Coy Starnes says:

    Ok, tried it last night, it worked great for awhile but the winds picked up around 3 AM and it ended up looking real bad this morning. I’m talking wind that makes the tarp go crazy floppy. It looked good shortly after I set up and tried it and was still looking ok when I woke up at midnight. I think I need to attach with something stronger then the factory prusik.

    • Derek says:

      是的,检查他们幻灯片的容易程度。我切换到klemheist结,他们工作得很好。另一件可能有助于一件事就是将半英寸脚踏板上的拖网进一步到达线路,远离吊床,所以当从Prusik / klemheist卸下线路到吊床时更加松弛,如果这是有意义的。

      I’m curious to hear if the winds pulled the prusik loose.

  8. 迈克戴维斯 says:

    Nice explanation Derek. A few years ago I did a stupid thing (don’t ask) and broke my Hennessey ridge line. My dilemma, how long should the repaired line be? I called Hennessey and they gave me a ball park dimension. I used the broken line ends and spliced into them with new cord from Hennessey. Also using Whoopies. I have the Asym ? Model that I had converted to full zipper from bottom entry (kept the bottom entry feature, just in case) so, here’s the question. How would you set up your Hennessey, and then adjust the length of your ridge cord for a perfect fit? I too have the bug netting wrinkle like some others have mentioned. Are you glad you started this thread???? Lol

    • Derek says:

      I’m surprised that Hennessy didn’t have an exact length for you. The bug netting is cut to fit so you don’t want the ridge line too long otherwise you risk ripping the net.

      The standard length is around 83% of the length of the hammock. For a 10 ft hammock that provides a ridge line of about 100 inches. This is a good average for Hennessy hammocks.

  9. tom says:

    Well done – very educational. I’ll be trying this with my HH and DIY hammocks. Thank-you.

  10. David B. says:

    Derek, I’m just getting started with the HH Expedition and just purchased the larger Hex fly to replace the smaller one that was included. If you had your druthers, would you pitch your tarp like you’ve shown here or fashion a separate ridge line like you’ve shown on your post about Using a Continuous Ridge Line? Which method do you prefer? Thanks!

    • Derek says:

      David, great question. There are cases for both variations, and you may find that one method works better than the other depending on the situation. Where speed, efficiency, and weight are optimal, you may want the “connected” version where the tarp is attached to the hammock suspension. With Snake Skin-style stuff sacks, the entire system works very well together.

      Pitching the tarp separate is particularly nice if you have a variety of tarps or hammocks that you switch between for different types of trips. For example, if you have a nice tarp but you have a “basic” hammock for winter use and a mosquito hammock for the summer. Pitching separate also gives you a few more pitching options.

      最好的原因是什么you决定 - 什么适合您。我目前真的很喜欢一体化的系统,因为我倾向于简单,高效的系统。当我第一次使用轩尼诗时,我的大挂起是篷布并不总是合作。现在我有一个解决篷布绷紧的解决方案,我发现它是一个非常可行的选择。我喜欢篷布总是以吊床为中心,无论我如何挂吊床。

      • David B. says:


        Thanks for your reply. I agree that I will have to test both methods and see which works best for me. You’re video also convinced me to rig my garage in some fashion so I can test setups more easily in a nice, controlled environment. I appreciate your insightful posts and very detailed instructions sheets.

  11. says:

    I’m an avid backpacker and just getting into hammock camping. I’ve been considering the Hennesy Expedition as my starter hammock. Thanks for the video, this is great stuff!

    Just a quick comment on the anchor point load (see comment at 5:35 in the video) that may not mean anything to anyone but me. For a 40 lb weight centered in between the two anchor points, an 8˚ hang angle should create about 140 lbs of tension in the cable. The 90 lbs mentioned here correlates more to a hang angle between 12 and 13˚.

    书呆子解释。也许这对携带木门中的计算器并想知道在他们设置时,他们的吊床上的人是有用的。每个锚点共享40磅的一半(每磅)。您可以使用几何形状计算电缆中的张力并使从锚杆和吊床向下的向上力的向上力。张力* sin(悬挂角)= 20磅。重新排列等式以获得:张力= 20 / SIN(悬挂角)。


    Thanks again for the explanation!

  12. 吉米 says:

    Excellent post. Thanks for the walkthrough. Of course Hennessy hammock makes good gear but all the better when it’s done right.

  13. Justin says:

    Ok this seems like a silly thing to have to point out, but doesn’t adding that much sag cause the tarp to be useless against anything but straight down rain? When I go camping it seems the rain comes horizontal. Doesn’t all the green you can see at 11:23 get wet?

    • Derek says:

      No, not silly at all. First, I need to point out that this technique is not restricted to asym tarps. The concept of attaching a tarp to the hammock suspension is what’s really interesting here. Many folks are skeptical about the minimal coverage on an asym tarp, and in some cases rightly so. I’ve been using asym tarps for years in adverse weather and can attest that they can work very well, even outside ideal, rain-coming-straight-down conditions. The video doesn’t illustrate well how the occupant will move the hammock away from the low-coverage area. That said, I’m not trying to convert anyone to minimal tarps, but rather show how to attach a tarp so it won’t sag once you get in. A hex, diamond, winter, or rectangle tarp will provide more coverage an can all be attached his way. I also used the Hennessy monsoon tarp connected directly to the suspension and it worked famously.

      正如我已经指出的那样,角度不需要exactly 30-degrees, so you can get the tarp closer to the hammock if need be, but not as close as folks try with a near horizontal hammock hang.

      I hope this helps.

  14. 吊床体验 says:

    How does this change the comfort of the Hammock? I like the flat position the HH offers, does this pre-angling change the final sleep position?

  15. Coy Boy says:


  16. Trekker44. says:

    好的,我用我的A-sym UltraLite尝试了这个。这对我来说并不理想。它确实稍微加剧了一定的速度,但它在臭虫网上引起了大量的凹陷。它还使睡眠位置更像是后院吊床 - 在中间非常悲惨。我必须在半夜重新装修。我喜欢这个吊床的舒适性,但它比我即将放弃的帐篷更难以置上。谢谢你的想法。我同意完全扁平的线路对装载力不好。

    • Coy Starnes says:

      Is this a Hennessy hammock? If so then I would have thought the actual hammock body would still be about the same lay due to the set distance between the ends of the hammock. Yes, putting in more sag will shorten that distance a little but not much. Anyways, before you give up on hammocks you might try one more time with a little less angle. Even a 20 degree sag will help keep the fly tighter than the way I used to pull mine almost banjo string tight.

      • Trekker44. says:



        • Derek says:


    • 我评论了我对脊线弯曲到脊线弯曲的解决方案的解决方案,以悬挂在30英寸的角度时,但如果我以更紧的角度悬挂吊床(轩尼诗似乎似乎推荐)。它确实留下了Bug网中的对角线折叠,但保持它的脸部。

      The suspension cord is strong enough for a flat hang angle, and there’s nothing magically right about 30⁰ beyond that being the angle at which the tension on each suspension line is equal to the total load—pick an angle that is steeper than the very flat angle Hennessy’s videos show but shallow enough for a comfortable sleeping position and you might be happy.

  18. al says:

    Thanks for your analysis and solution of the sagging-fly phenomenon ! Better self-flattering than fly-fluttering…
    I used to hang my first generation non-asym Hennessy (with a bigger fly) and very straight by passing an extension of the prusiknot through the anchorpoint and back to the fly. This made for a a selftightening fly suspension system when the hammock was loaded.

  19. C neill. says:



    我使用您所显示的30度角法在侦察吊床旁边的露营地面设置了我的Hennessey Hammock。


    Your hanging method saved us and I am not kidding. I have used my Hennessey probably 50 times plus and have had leaked problems because I didn’t understand the reasons why.

    Your video was the difference and I can’t thank you enough.

    • Derek says:

      Thank you! This was reassuring. I’ve been reading comments of people who I don’t think watched the video and I’ve been considering making a follow-up (I still might). I’m glad it worked for you!

  20. Powell says:

    Hi Derek, Just stumbled across you site and really like the info. I have the XL deep Jungle but I do not sleep well on my back like a banana and get back pain. Decided to do this next Rubicon run using the hammock as a tent with a 4×6 air mattress under it, and it may rain on us in 2 weeks. Also thinking to set the tarp high sit under with out it touching my head. any suggestions? Thank you in advance, excellent write up., Powell

    • Derek says:

      Did you see my post on how to stay comfortable in a hammock? If you sleep diagonally you will flatten out. Much more cozy. I’ve got other tips in that post.

    • Derek says:

      Using the hammock as a bivy is certainly possible. I’d rather hang it up but go for it! Use trekking poles or sticks to hold up the tarp.

  21. 约翰尼 says:

    How is the lay on the HH? Any flatter than others? I’ve been using a Treklight double hammock for a couple years but I’m considering going back to the ground unless I can find something that lays flatter. Not a fan of the kyphotic alignment, hyper extended knees, head pushed forward positioning that I get with the Treklight. I’m wondering if the asymetrical cut might make a difference? Thanks!

    • Derek says:

      The HH won’t help those concerns. It’s a tad smaller inside. A flatter hammock would be the warbonnet blackbird or the UK hammocks xpedition. The foot box and larger size helps a lot. For a completely flat lay, I would go with the Warbonnet ridge runner.

      • 约翰尼 says:

        Thanks Derek. I’ll definitely give those some thought. The ridgerunner is an interesting idea…I’ll have to compare the weight with my current setup.

  22. Coy Starnes says:

    约翰尼, to add to Dereks comments, I find that the bigger hammocks definitely lay flatter than the smaller ones. And by bigger, I mean longer, although wider helps too. I’ve tried several sizes of Hennessy Hammocks and a couple of other brands like Speer and Crazy Creek and the bigger ones always felt the most comfortable. Same for my homemade ones. I have not had the opportunity to try a Warbonnet but Derek has so I would trust his input.

  23. 弗农 says:

    德里克,你知道HH是左右y hammock, or does it matter, I’ve heard that the asym design dictates this to a degree (I am a right side sleeper due to sinus issues).

    • Derek says:

      The HH hammocks have a head left, feet right design. I’d have to check if they offer a flipped design but I don’t think so.

  24. Greensleeve. says:

    Would an HH benefit from the addition of a structural ridge line?

  25. Greensleeve. says:

    Thanks, Derek. I wasn’t clear on that point.

    Any plans to put on any hammocking seminars in Georgia?

    • Derek says:


      • Greensleeve. says:

        吊床开始与我在玛丽埃塔的儿子的侦察部队抓住。两个周末前我的第一堂课和我倾向于轩尼诗重新(经典和邮编),我的Webelos II投球,由临时篷布覆盖。(他在即兴创生间是一个自然的。)他们从来没有在吊枕以外但却爱过它。


        Meanwhile, do you think the Expeds will do just fine for our upcoming mission trip to Haiti? Or should we spring for hammocks, Hennessy or otherwise, with “jungle” in their branding?

        • Derek says:


          If you wanted to sponsor a hammock clinic, it might be best to work with the district or council to get broader support and attendance. I only ask for travel expenses, if possible, to cover fuel, meals, etc.

  28. 马特G. says:

    I think I see another benefit to using a prusik (or klemheist) on the non-moving side of the whoopie sling’s adjustable loop: no more pulled-through whoopie slings! I made four whoopie slings a couple of years ago, and it took just two microseconds of stupidity and carelessness to bring that number down to two. By leaving the prusik/klemheist cord in place, the adjustable loop can’t pull through. Is there something I’m missing here?

  29. Expat in Japan says:

    Thanks for a very informative site, and for this article. I think it’s the solution for a problem I’ve been wrestling with.

    In order to hang in wide open spaces with trees really far apart (for breeze, sun, views, and whatnot) I use slightly unusual suspension: long lengths of static cord tied to each end of my tree straps. I throw one end up over a high branch, pull the tree strap up, and have it wrap around trunk. Then I just connect both cords to one end of my hammock. The second cord adds weight but it makes it easier to retrieve it during takedown.

    Cheers again!

  30. 马特G. says:

    While I was lying in my hammock this morning, feeling the wet spots in my underquilt and feeling sorry for myself, I lamented that I couldn’t adjust the tarp tension while IN my hammock. But then I thought, well, why not? What if I: (1) tie a small bowline in the end one of the tarp lines and run it out to the prusik loop on my whoopie sling suspension, and then back under the fly to the center; and (2) take the other tarp line out to the prusik loop on the other whoopie sling and back under the tarp to meet the bowline in the center. Now I sit in my hammock and tension the tarp from there (running the second line through the bowline and back to a butterfly knot to get a little extra mechanical advantage). The lines will also serve as a ridge line. I’ll try it later today after the rain stops. Does anybody see any flaws in this plan?

    • Derek says:

      Sounds like an interesting idea! Let me know how it works and we can illustrate it.

      • 马特G. says:

        Thanks for the encouragement, Derek. So far I have discovered a gripping knot which works better for me than either the Prusik or the Klemheist. It’s the Distel knot, and I found some people on Hammock Forums talking about it. The other two knots work well on the bury part of my whoopie slings, but not a single thickness, and not two single parts side by side. I am using 3/32″ paracord on 7/64″ Amsteel with no slippage so far.
