One long rope or heavy spectra cord with two prussik loops attached...(allows for nearly all types of hammock ends to be used)...the rope allows for hanging from two anchor points WAY apart, the hammock is tensioned on the loops attached to the rope......as the hammock sags, the rope serves double duty as the Tarp ridgeline.....(weight will be an issue for the ultralighters / I understand that - maybe...How heavy would 25 to 30 feet of Spectra cord capable of safely supporting a hammock be?)
a link or two to prior discussions would be appreciated....
Not to discourage you or anything, but ....
I hang my tarp from a ridge line using Prussiks. Makes it easily adjustable. So in my constant search for easier and simpler, like you, one day in the distant past (more than 12 months back), I thought why not do the same thing with my hammock - hang the line tree-to-tree, 2 Prussiks, and hang the hammock from the Prussiks.
So I took some 2.8 mm (approximately 1/8") diameter Spyderline for the tree-to-tree line and used more 2.8 mm Spyderline for the 2 Prussik loops. I know, I know, same diameter, but since this isn't a climbing application, I thought it might work.
Used the Spyderline because of the polyester sheath over the dyneema core.
Strung the line, hung the hammock from the Prussiks, slid the Prussiks to adjust and thought "this is great".
Slowly and gingerly sat on the hammock, then slowly and gingerly swung my legs aboard and slowly and gingerly laid down.
Ahhh - I like this.
Then I shifted my weight.
Heard this horrible screeching noise and simultaneously dropped a few gut clenching inches.
Slowly and gingerly I swung my legs out of the hammock and slowly stood up and started breathing again when my weight was free of the hammock.
Checked the line and Prussiks. The foot end Prussik had slipped and slid about 3" to 4". The polyester sheath where the Prussik had slipped was smooth as glass and quite warm to the touch. Not the usual rough exterior. Tried to slide the Prussik back to it's original position. I couldn't budge it.
Unhooked the hammock and tried to untie the Prussik that had slipped. Very difficult to untie. The heat caused by the sliding Prussic had literally melted the polyester sheath of the tree-to-tree line and the Prussik cord and melted the two lines together.
I then took another line, 1/4" diameter, polyester sheathed dyneema core line and used that for the tree-to-tree line and the 2.8 mm Spyderline for the Prussiks.
That combination worked very well. Got in the hammock and vigorously bounced around. No slippage. The Prussiks adjusted easily and held very well.
Then I held that 1/4" diameter line coiled in my hand and decided that for car camping it would make an excellent suspension system. But for backpacking - way too heavy and the bulk of the required length left little room for anything else. The 1/4" diameter line is even more bulky than webbing.
So - conclusion: when using a method of transport in which the bulk and weight of the 1/4" diameter line isn't much of a consideration, the Prussiks on a line is an excellent means for hanging the hammock.
