“as far as I can see, no matter how you’re attaching the whoopie sling to the tree strap, when you expand the whoopie sling to its longest, it’s making a big (seemingly inefficient) doubled up loop.”

You are correct, and I was very confused back when I posted these. 🙂 A whoopie sling, at it’s longest, will always be a big loop.

Look into something called a UCR – Utility Constriction Rope – if you really can’t stand to add an extra ounce or two (like by buying hummingbird’s suspension extenders.) It uses the same constriction principle as a whoopie sling, but not in a loop – CAREFUL though, if you don’t use it properly it can drop you like a rock. Some tutorials show how to add a “safety knot” that helps ensure the UCR doesn’t slide on you, I’d recommend that.

Here are some links-

(Sorry, I know this is from almost a year ago, but I just stumbled across this thread.)

I own a pair of Hummingbird tree straps and live in the redwoods, so I’d be very interested in making them longer at the same weight… Could you explain what you mean by switching around the straps? I see that end of the whoopie sling near the bury is larksheaded onto the strap. How would you change it? As far as I can see, no matter how you’re attaching the whoopie sling to the tree strap, when you expand the whoopie sling to its longest, it’s making a big (seemingly inefficient) doubled up loop. How could you reattach it to make it more efficient? Or by switching it around, do you mean that you undo the larkshead from the tree strap and attach it to the hammock’s continuous loop. Not making it effectively longer, just changing where you clip your carabiner… Could you clarify for me?

No.

The whooie sling. I was thinking there was some way to use the working end to attach the hammock if it were turned around, but it’d just slide all the way closed without ever cinching down.

Yes. That’s how I do it.

I’m not sure I follow you. A whoopie sling can be attached to the hammock side or the strap side and work the same. It doesn’t matter which side it’s on.

The hammock? No.
