    Single Line-No Hardware-Structural Ridge-Half Whoopie-Fully Adjustable-Suspension

    Guys I need some opinions, I have this idea for a suspension but I need to know if this is going to work before I order some Amsteel. I love the single line suspensions but I want one more adjustable and I want to use as little line as possible so I came up with this, will it work?

    1. Start with the tree huggers, single loop sewn in the end, feed the other end in the loop pull tight.
    2. Add a toggle on the free end.
    3. Then I created (in my mind) a half whoopie, basically it is about 24 inched of Amsteel used to create a loop on one end (this goes on the Toggle) Then I take ridgeline and burry it in most of the half Whoopie.
    4. The Ridgeline is a single length of Amsteel, what I hope to accomplish is to have say 10 feet (5 on each side) for adjustability. To do this with a common Whoopie you would need 20+ feet of line (10 on each side).
    5. Create two continuous loops, use the loops to tie Prusik knots on the ridgeline, then Larks Head to the Hammock. Prusiks are adjustable.
    6. A 20’ length of Amsteel gives just less than a 20’ Adjustable Span.


    Parts List
    2- Treehuggers
    2- Toggles
    2- Half Whoopies (24” of Amsteel)
    2- Continos loops (18” of Amsteel)
    1- Ridge Line (about 20’ of Amsteel) Calc ulate this: Your custom Ridge Line Length plus whatever you want your adjustability to be.

    My Major Questions:
    • Will a Prusik hold on Amsteel? The small diameter might require multiple wraps.
    • Is the holding power of the bury going to hold in this configuration, will it take more bury length?

    Your half whoopie is actually a UCR (utility constrictor rope). Prusiks will hold on amsteel, but once you get it to hold it will probably lock up, if it slips just add more turns.
    I'm think 11" of bury will hold just fine. Careful with UCR's tho' as they are easily unlocked by a bump on their tail. Leave the tail long and tie a barrel knot around the srl then when you milk the bury pull on the barrel (it acts like a cord lock) and that should help keep it loaded.
    Good luck,

    I think I've seen on one of Grizz's videos, he connected that loose tail to a prusik to keep tension on it. Another option for you...

    yup, here it is...

    That looks great to me, its very similar to what I have.
    I have a continuous loop through each channel a through a rap ring. Then a woopie from the ring to the tree strap, and a ucr between the rings as a Srl.
    The rings look neat and clean and should work for the underquilt, if I ever made one or buy one.
    Your use of the pressick is very nice and probably a smidge lighter..
    Order lots of amsteel. It's fun. I got a 600' roll last week. I'll use it to replace the deck lines on my kayaks, and store enough in the boats to line them around rappids.

    How about just tie a toggle into your line at the tree hugger on each side. or a prussic knotted toggle?

    One could use shorter/lighter tree huggers, make the half whoopies longer, and thus attach to larger trees.

    Would the prusiks be helped by simple knots in the SLS at the proper distance? I wonder how much knots derate the line vs. a prusik that may or may not hold. I suppose a soft shackle can double as a prusik?

    A UCR, huh?

    Hmmm, just might try that. Lighter and simpler is a worthy goal. I like my system's ability to keep the tarp flying high in the summer. But it's not summer!
