Is there some advantage you found using the two pieces of rope as opposed to attaching the rings directly to the carabiner?
Plus I get absolutely zero slippage this way - and hanging is a breeze - set the tree huggers, set my 'biner, pop the loop over the gate and yank, done.... Next!
That's a really interesting approach. I guess the only downside, if using the stock suspension cords, would be that it significantly shortens the possible distance between trees right?
You would be correct that it shortens the maximum possible distance between tress. However, it isn't a permanent setup, so if I found that I needed more length then I could either remove the rings altogether or just move the rings up the line towards the trees. The rings are only there for convenience, and if convenience suffers due to available trees then I just switch to whatever is most convenient at the time.
How were you connecting the rope to the rings and what size were the rings?
Also of interest:
* What kind of hammock and were the suspension lines stock or DIY Install?
* How old were the suspension lines? (Suggesting maybe the sheath simply rotted to the point of failure)
* How were you looping/lashing the rope though the rings? (Suggesting maybe too much friction in a single point)
* How often did you keep the rings in the same place? (Suggesting repetitive injury to the ropes at the same point - iow, did you always look for trees 12 feet apart and hung your lines the same way every time)
* How often do you inspect your lines? Was there noticed deterioration? (Suggesting the injury to the rope wasn't visible for one to notice, thus no care taken to prevent hitting the deck)
* Was this (just by chance) an attempt to purposefully test your suspension lines to a point of failure? (Suggesting an attempt to "see how many licks it takes to get the center of a Tootsie Roll Pop")
I ask all of these questions merely out of an inquisitiveness towards the opportunity to learn failure points for the various ropes in use out there. In my younger days I rock climbed and rope maintenance wasn't optional, it was the difference between life/death. However many a folk would climb without ever conducting any review/maintenance, sometimes they won, sometimes the rock won...
Point is, I know what to look for in climbing gear, and I wouldn't suspect any difference in the lines used on hammocks, but in the off chance that it was -
....pictures or it didn't happen...
As WetRivrRat suggested maybe I put too much friction in a single point.
I have the UL Explorer, the ropes are pretty thin and don't work with the garda hitch (two rings). later i found all the people talking about how it is bad for the ropes. I have made a new method, only using one ring on each side. i tie a doubled figure 8 on the end of my ropes, put a single wrap on a pretty small rap ring, then feed it through the end of the rope through the webbing and stick a biner on the figure 8. You just clip the biner to the ring and it stays adjustable, havne't had any slippage as far as i can tell. doesnt need slippery half hitches either. Saves time and a little bit of weight not carrying 2 more rap rings. i'll take some pictures later and post them.
