Which measurement do I input into the tool? I was bored so I worked out the equations with the food end higher than the head end. Dear Derek, your calculator is wrong: But remember, this is HALF the distance between the trees, so you have to multiply by two.
Then your calculation is correct, but perhaps you could add the fact that the angle should be calculated with a loaded hammock: I was confused for a while. Bye and sorry for the misunderstanding, Lorenzo. The page works fine, but the numbers are all wrong. I rarely take a stool backpacking. I tried this with varying distances and the calculated heights and lengths are just all wrong, giving me similar results. What part do I not understand? Show me the numbers. What is the length of your hammock?
What angle are you hanging? Are you using a ridgeline? I went down to my subterranean laboratory and came up with some numbers. For the right angle, the strap lengths are way off. I can adjust the sit height by lowering the hanging point. Please email me directly so we can coordinate a good time. Do you think this is possible? Derek, first of all, great app! I have a probably silly question, but I have a cotton hammock and it seems to have no, or basically no suspension length.
After the cotton hook latches to the bolt on the wall, the webbing begins immediately… how should I use the app in this case? Should I consider the webbing part as the suspension length? Also, any good ideas on how to shorten this type of hammock, should I just tie knots? It looks like you have a traditional Brazilian or Mayan hammock. Those strings are called the nettles that all combine to the clew.
This is all part of the overall hammock length. Some of those hammocks can be as long as 14 feet or more. This is the length you use in the calculation.
The suspension is what attaches to the hammock and spans and distance to the anchor point. For some of my hammocks indoors, they just clip on to my bolts. Other hammocks need a short suspension to reach. I hope this makes sense. Do you hang the eye-bolt higher on the foot end? While camping, I usually will do a bit of both but was not sure how I would compensate indoors.
It depends on your hang distance. I just shift my body by putting my torso more center and my feet higher in the hammock. One question…I want to hang my hammock closer to 1 end than the other. My details are; — Distance between anchors 4.
I assume the above only applies if the suspension length required is even at each ends, if not, the different heign anchor points are required…Correct? How would you suggest I work that different suspension lengths with your calculator.
I have tried to adjust the actual distance between anchors 3. It gives me achor point at cm high. Then I readjust the distance 5m again until I have the required remaining suspension amount of cm.
This give me an anchor point of cm high. The calculator helps with a starting point, but you can modify from there for sure. Shortening one suspension length has a similar effect to raising one end higher than the other. Any advice on deciding how high to make the hang points or the highest ones — perhaps it could be built with a few different options available? And for those who are interested, ENO actually has 3 hammock stands coming soon, which is really cool!
I would use a set of the ENO wall anchors and then use a short cord loop where you could connect your hammock. If you put the anchor point at the highest point you reference, you could then hang your hammock at a higher angle 45 using the loop extender, or at a lower angle 30 by clipping directly to the anchor bolts. This is what I do in a few of my rooms to accommodate a few different hammocks and give me some flexibility.
I think I figured it out. I have to measure the angle with me in it, which gets easier when I have a second pair of hands. The numbers check out. Yes, the calculator looks at straight lines. I use the calculator and have your book also. We want to try some short overnight camping trips this year but do not like sleeping on the ground anymore.
I hung the hammock in the house and it worked out great using the calculator and a tape. My wife said this was better for her she has a bad back. Is it ok to do it this way or should I put in a new hook higher for the foot of the hammock? We are both in our 70s and did not want to hit the floor. Yes, taking the hammock off center has a similar effect of hanging one end higher.
The calculator make it a lot easier for me plus learning a lot from your book, I have also made some of your DIY gear from the plans on the web site. The walls are brick on one side, and sandstone on the other. Any guidance gratefully received. That sounds like a good idea. Using the right type of anchor bolts for the material is key. Any updates in future? The Google Play link needs to be updated.
The web version should work on any internet browser. Try tabbing to each input block or click into each one to see it change the result.
Wow, Derek is really on the job here! For my hammock, I over-engineered, which is to say, I went big without doing any calculations. I laid out the hammock on the ground to see where I needed the two pipes to be placed in order to hold the hammock at the right height and angle, knowing I could fine-tune the distance with a length of chain later.
When I take it down, there is nothing in the way, and only two pipes and the hammock to store. You want to get a straight line measurement, not necessarily loaded.
You can pull down the center of the hammock or put something light in the bottom to tension the hammock. Hey Derek How can I download that hammock calculator as a jpeg? Often, I find myself trying to hang a hammock off-center — closer to one tree than the other. So basically, I find the optimal hang for a centered hammock, and then end up adjusting the hang point and suspension length on each side to maintain the angle and move the hammock closer to one of the trees.
I just verified what I suspected with my indoor setup. I hang from rafters in my basement that are about I was considering a Wallaby, or something smaller, as a second hammock, and also as a possible hammock to hang from the backyard stand we have with the typical rope hammock with the spreader bars as my Roo is way too big.
This will tell me what I could expect from that. Hi, I have a 9ft hammock, and would like to buy a hammock stand for my bedroom. What is the shortest stand I could possibly get that would work comfortably with my hammock?
Hi, I purchased the calculator for my iPhone. I entered the hammock length ENO single nest as inches. Calculations happen and when I look the ridgline length is filled in as This makes sense as the length of the hammock stays the same and the curve of the hammock would shorten the ridgeline.
Am I missing something in the app? Using the numbers I input the numbers are different for susp length and hang point. Sorry the numbers are different between the app and the online calc with respect to susp length and hang point. Any thoughts on this. Think when I did this the suspension length came out wrong. The ENO is a fairly short hammock. I believe the default ridgeline length in the calculator is the same length.
I need to confirm that. Hi posted a bit ago. Purchased the app a ways back hanging an eno double nest indoors. The app and the online calculator give me different numbers The online version seems to calculate the ridgeline length and thus the suspension length is different Here are the numbers I am using Eno length of hammock inches Online says ridgeline becomes 97 App says ridgeline is If you find it difficult to install anchor points for your camping hammock, this hammock hang calculator from The Ultimate Hang will make it easier for […].
The last developer update was over a year ago on August 30, Has this app been abandoned or is it just un-updateable? Hope that there is hope for this app, as I would really like to make use of it.
Thanks for any clarification you can provide. Bruce, thanks for asking. The issue has been supporting all the different device resolutions. The developer has assured me that the new version fixes all this and we have been trying to figure out how to get it updated as soon as possible.
This distance prevents you from hitting the ground when you lay on it. This calculator could help with the […]. This calculator could come in […]. So for a given load at the bottom aka hammock, the straps from the tree to the hammock ends, do they take the same load, or is the load split between them?
Oddly, I see reviews of the lbs failing, due to, reviewer guessing, manufacturing defects? Hammock straps are often given a safety factor of 4: Be sure to check with the manufacturer first on how they make that claim.
Some just list the breaking strength e. This allows for the dynamic reality of hanging in a hammock. My mexican style hammock does not really have ridgeline length.
It looks like this: How should I measure? Knowing that, I would not have paid for it. Please update this web page. Or update the app, either way. But as it stands right now it is misleading to the point of fraud. It was an oversight. If you would like a refund, please submit to the iOS store. Please note that I am working to bring the clinometer back it was in the first version, but was too costly to update in the latest update.

Another variation is the sit swing, which holds the receptive partner upright in sitting position, rather than supine. The main purpose of sex swings is to make sexual intercourse more exciting and effortless. A sex swing may enable greater freedom of movement during intercourse or assist with challenging sex positions. Sex swings can enable individuals with a physical impairment or disability to enjoy a wide range of sexual activities.
Individuals with muscular weakness or arthritis may use a sex swing to reduce the strain on affected muscles or joints. It is important to follow the provided instructions when using a sex swing. Secure mounting is vital to avoid injury to the suspended partner from falling. The use of toggle bolts , such as would be used to hang a dreamcatcher, is not appropriate.
The spreader-bar hammock is easily recognized by wooden or metal bars at the head and foot of the hammock, spreading its width and allowing for easy access for casual use, such as in a backyard. Unfortunately, the spreader bars also make the hammock unsteady since the metacenter of the hammock when sleeping is very high. This style is generally considered less stable and less comfortable for sleeping than other styles.
A subset of this style is the single-spreader bar hammock, which uses a spreader bar on only one end and is much more stable. A variation of the single-spreader bar hammock has three attachment points, one at each corner of the spreader bar and one at the non-spreader bar end and is nearly untippable.
While the various styles of hammocks available today are similar in form, they differ significantly in materials, purpose, and construction. Mayan and Nicaraguan hammocks are made from either cotton or nylon string that are woven to form a supportive net.
Mayan Hammocks have a looser weave than Nicaraguan hammocks, and the supportiveness of the hammock "bed" depends on the number of strings and quality of the weave. Brazilian hammocks are made from cotton fabric and usually more durable than the string varieties.
Naval hammocks are usually made from canvas or strong cotton. They are intended to be durable and stand well the hardships of shipboard use. They usually are simple and undecorated but robust.
Venezuelan or jungle hammocks made today are generally of breathable nylon or polyester, and use dacron or similar non-stretch suspension lines.
They are "inline" hammocks; like the canvas naval hammocks of old, the occupant sleeps along the length of the hammock, rather than across it.
With their breathable false bottoms, drip strings, sandfly netting, and optional rainfly, they are one of the most secure hammocks against not only water entry, but also insect stings or bites.
Travel or camping hammocks are popular among leave no trace and ultra light campers, hikers, and sailing enthusiasts for their reduced impact on the environment and their lightness and lack of bulk compared to tents. They are typically made of sturdy nylon parachute fabric which may use ripstop techniques to improve durability.
Some hammocks feature a mosquito net and storage pockets. Some types offer a ridgeline to make set up easier, and may also include a slit for entry through the bottom of the hammock.
Special webbing straps called "treehuggers" are used to loop around trees in order to create attachment points for the hammock. For non spreader-bar styles, the way in which they are hung is critical for comfort. Generally, a higher attachment point is preferred as well as sufficient length between points, though these two dimensions can be adjusted to compensate for a lack in one or the other.
Though one can lie in a hammock lengthwise or across its width, most hammocks are best used with a diagonal position, as it provides the most room and support. Users with back and joint pains often report some relief from these problems when sleeping in a hammock in this manner.
