I purchased a Grand Trunk hammock a couple years back (not sure of model tag lists min.weight 300lbs and is very light.) I've used it a few times as a cat-nap gig on some trips where others were carrying large tents.
My problem is that on a recent trip, while only carrying my hammock, the tent would NOT stay off the ground! Every time I sat in it, it would strech all the way to the ground. I tried stringing it in multiple ways (as tight as I could get it, with a little slack, etc.) when I returned home from the overnight I purchased slap straps (was using DIY straps from 5mm rope) with no success either.
Has anyone else ever experienced this issue? I can't seem to figure out what's changed from the last time I use it a year or so ago when it worked fine!?!?!

Excuse me the "hammock wouldn't stay off the ground"
Not sure why I typed tent lol.
I think you were using 5mm climbing rope which is designed to stretch under load by 10 to 15% its original length to absorb shock during a fall.

LOL... I don't mean to laugh rgardin12 but the "word picture" is making me giggle... :) I hope someone can help you out. Sounds like Rasty might be on to something.. maybe?
The slap straps will stretch also.

Get some spectra cord, or some 1-inch seat belt webbing, or both. The 5mm rope will stretch a lot, as will slap straps (as noted above.) Or look at whoopie slings and straps at BIAS (http://buttinasling.com/suspension.html).

Freudian slip.
Deep down you're a tent guy.
Well, it is a "hammock tent" so either works. I just like using "hammock" to separate myself from the ground-bounders. The first couple of times I used my Hennessy Hammock it sagged a lot. I learned the proper knots and got it to behave. It stays where I put it, now.

Your probably right lol. I love the comfort of a hammock but over the years I've never gained a true level of confidence in them.
I am going to give it one more go and try to figure this out otherwise I'll prolly just stick to the ground lol
Rasty is correct, and the slap straps are made of material that will stretch also. Watch these videos they should help http://www.youtube.com/watch?v=d7NZVqpBUV0 Shug knows his stuff and check out hammock forums for multiple suspension systems that will work http://www.hammockforums.net/forum/forumdisplay.php?f=86 Happy hanging :)

You need to use the correct grear for the job. Have you attended a group hammock hang ? You can learn alot about hammock setups at one. Sounds like you were using nylon cord and or straps that will streach,

Plus Shug is very entertaining!
If you give up on the hammock, and go to the ground, give me a shout. Good enough price and I will buy it. :)

Well this question has been answered well I too had that issue once... The ropes and straps may have to be replaced - stretch the knots tighter and wear it in... the stretch will stop with use.

I see you've got some good answers. Nylon bad. Climbing rope bad. Twisted line (instead of braided) bad.
And no, the stretch won't stop, since it's designed into those products on purpose.
Also, what about the angle of your hang? The distance between your trees? Size and strength of trees? All these can add to a hammock getting too low.
The "proper" angle of a hang is 30 degrees. Less than that (too taut to start with) and the physics/geometry/leverage of things multiplies your weight. So, start with a good hang angle and the hammock will drop less.
And yes, Shug and www.hammockforums.net are GREAT sources of info.
Enjoy your "tent in the air" or as my wife calls mine, your "bear pinata!" :D

I also have GT hammock. I puchased a separate suspension system (http://www.jacksrbetter.com/shop/hammock-suspension-system-complete-set/) from JacksRbetter and haven't looked back. It will solve all your problems :-)

As a cheap, if heavier alternative, you can use over sized line (3/8 nylon), and avoid the stretch. It has worked for me, though I'm looking into better alternatives.

sounds like I just need to do some more reading.... I'm just not sure how I didn't run into this issue with the same gear the first 2 or 3 times I took it out.
