I love this type of analysis even though I could never attempt it myself. Many thanks for performing the experiments and making this video. Cheers from Down Under.
Thanks for watching. SRS = Single Ring Suspension. The guy who thought it up wanted to be able to use trees that are closer together than a whoopie sling allows. So the 10 inches or so of bury on the whoopie sling is replaced with about 2 inches of ring and wraps. More or less.
Thanks again for the great Video and welcome back. That being said I have been using SRS using Spyderline on an 880lbs rated replaceable Link with no deformation to the line like you have seen on the amsteel
You have no idea how many different new ways I just learned to hang a hammock just by watching this vid. 4 of which you didn't show. 😉 Much to my son's dismay, my mind is swimming with more comfortable and convenient ways to hang my hammocks. Looks like I'm gonna teach him the basics of friction knots
Great intermission but dang by the time you had the first ring done I would have had my hammock setup done already. But in saying that I found out something new about hammocking, which it is my preferred method of camping. Thumbs up from me
My personal choice is permanently fixed ring at the hammock end, cord with fixed eye looped over a Marlin Spike hitch, run to the run and tied off using some slippery knot (e.g. slippery buntline hitch). Embrace the knot!
Enjoyed watching this classic video again. I love the way you operationalized and modeled the final question. Very interesting results. Bravo! Respect and regards, Chris AKA kitsapcowboy
Awesome episode Prof. I have two questions. 1- Why would anyone wan to use a single ring suspension when the whoopie only and NO RING means less weight. Two rigs would be too much weight so I don't understand why take the rings. 2- What is SRS? thanks for the videos. Big Fan.
I have gravitated (scientific term) toward using rappel rings in conjunction with a titanium marlin spike on my Warbonnet Ridgerunner. The original pentazoid buckles that come with the WBRR I find problematic for my older fingers to deal with undoing especially when cold and wet or when the suspension is cinched down tight to flatten the lay of my bridge hammock. Therefore, I found that I prefer larger dual rap rings instead of the OEM pentazoid buckles. However, I have found that although the fatter rap rings are indeed easier to adjust and undo, they may slip under load. So, I found that I could loop a bight of the flat webbing back through and slip a marlin spike through the webbing bight. The results were both secure and by removing the spike and pulling on the webbing it all comes undone, a great combination. My next experiment was with a single rap ring replacing the dual rap rings. I wrap around the single rap ring three times; position the hammock as desired; form a loop around the marlin spike inside the single ring; and complete with a half hitch around the spike on the outside of the rap ring. Envision a clove hitch around the marlin spike with the rap ring in the middle. The advantages are that I can easily adjust the length of the suspension and hammock tension/height by first sliding the hammock suspension through the triple wraps followed by locking into place with the marlin spike (easy peasy); It easily comes undone by pulling the marlin spike out regardless how much tension is on the suspension (great for old/cold fingers); It reduces the weight and space by one rap ring on each end; and there aren't any squished amsteel weak spots. Maybe I should make my first youtube video, eh?
This is wonderful! I'm loving the modeling and good science you have. I'm an engineering student so this is my kind of hammock analysis! hahaha thanks for doing all this.
I'm assuming this did not use periodic boundary conditions, so edge hammocks need to be fully contained within the area, and can't span around the edges?
I tried the SRS on a stock HH and the cords looked good. Could be the same with Spyderline, especially if you avoid the evil wrap closest to the hammock. Hang on!
your last words make me thinking.... what if I need to hang my hammock higher than I willing to fall? say in specific mission on hostile area or in area that there are a lot of wild and dangerous animal? what kind of setup do you recomend?
As density increases over a random distribution, competition and ecologic carry capacity would factors to consider dependant on species, canopy size etc...
True that. I'm having fun thinking about how to alter the random placement model to accommodate. It's easy enough to imagine altering a sequential placement model, as one places 'the next' tree the placement is not uniform spatially but accounts for biological factors, some of which may suggest affinity...common seed spread perhaps, some which reflect competition. In the longer run (long enough for trees to grow large enough to hang from) competition will dominate affinity. Musing.... thanks for the insight.
In this video, you seem a bit limited in your choices of termination... why all the hardware? Why not just use simple cordage and straps? Why use an old style gathered hammock? You might mention water... there have been experimental studies (on TH-cam) of methods to eliminate water flowing or seeping down the support of a hammock. The result was awesome! A simple drip string (larks head) worked best! NO hardware worked well, if twisted... and who could guarantee not twisting a little?
I'm hardly recommending this approach, indeed I put this together to argue that its not a recommended idea. Perhaps I was too subtle. I go over cordage and straps in other videos. Choice of hammock hardly matter when what you're trying to do is assess a connection technique that might be applied regardless of hammock type. I find that the hanging tail of a whoopie sling or UCR placed at the hammock end of the connection rather than the tree does a fine job of working as a drip-line. cheers
ProfessorHammock LOL I'm a bit of a dunce for not picking up on your "subtle" hint! I loved the analytical approach to making a decision, not just flying by the seat of your pants. Most people have never even considered the constraints! Does that observation give away that I'm an engineer? Thank you for your reply!
The dutvh biner have sharp, relative, edges compared to a round rod. I have SMC rings and if I was really anal would use a sub ounce climbing biner. This is not the same way to use a RING suspension as you had showed in your suspension 2 video a while back.
dutch's long carabiner is for tarps not suspension, a professor should know that, his suspension carabiner is solid. obviously hostility there. boo for you
Dutch is a buddy, and we have a running thing knocking each other in videos. Guy humor straight out of high school. This professor does know what is proper and improper use of life-critical equipment.

What a great video! Thanks for the scientific approach + modeling!
Not your average hammock tester. I like it. Thanks for the computer model as it confirms a few thoughts I've had myself.
thanks, your appreciation is appreciated
thank you. this video was quite help full

Love all of your tutorial vids.
I would like to see a video of how you hang your personal set up from beginning to end
My personal choice is permanently fixed ring at the hammock end, cord with fixed eye looped over a Marlin Spike hitch, run to the run and tied off using some slippery knot (e.g. slippery buntline hitch). Embrace the knot!
is this gonna be on the final?
Bravo! It would be fun to do something with game theory and hammock hanging!
glad you like it! Analysis of models is an acquired taste....
I had fun too! Warmed my heart it did to have one of those things bust dramatically on the first try. Hammock science with a visual attraction.
Super video!

Hey, I have some of those same books from your desk!
+Jake Tarren Ha! I'm betting it is either Kleinrock, or Schneier. Classics.
+ProfessorHammock both actually! Also, you're videos are pretty great, so keep going off on engineering tangents, I actually learn a lot.
I'm assuming this did not use periodic boundary conditions, so edge hammocks need to be fully contained within the area, and can't span around the edges?
Thanks! I like making 'em, time's the issue these days. Horray for Christmas break!

I appreciate it. I like modeling and simulation...!
your last words make me thinking.... what if I need to hang my hammock higher than I willing to fall? say in specific mission on hostile area or in area that there are a lot of wild and dangerous animal? what kind of setup do you recomend?
You would have to hang the same way climbers hang in a portaledge.

Oh Yeah, Aloha and Happy New Year!
Awesome I missed you PH :D
He has a master's degree...In hammock! Great to know you are another hammocking fan of Ask Dr. Science!
Why not use a taught line not?
ENO slap strap
