    I would go with Polyester webbing. 3500 lbs breaking strength. You gonna need it if you've got 400 lbs to support. I used polester webing for a year and it finally started tearing around the rings. So I upgraded to polyester. Polyester doesn stretch anywhere near as much as polypro.

    Also forget 1200 strength rope go ahead get the 1900 lbs stuff or above.

    Fabric? I'd use two layers of 1.9 ounce ripstop. Your talking 400 lbs here man, not 250 or 260 lbs.

    If you want to stay alive, overengineer the thing. Then try to cut down weight.
    Forget those stinking knots. Go with the ring/buckle supports and figure 9 tarp tensioners.

    Both of the hammocks I made so far as tests have been whipped, not knotted.

    The doubled material one is likely stronger, and somewhat redundant. When it's under tension each is supporting half the load. It's unlikely though that if one fails the other will be enough to keep you up, the second then would have to support the full weight.

    I also used polyester webbing rated at 1500 lbs for the supports on the doubled one, using a larkshead just below the whipping.

    On the 1.9oz version I am currently using the ringbuckle system. The ringbuckles are attached to the same rope which makes up the whipping, using something similar to a sailor's whipping, but with an overhand knot underneath the whipping itself. The ridgeline is attached to the other end of the whipping rope in pretty much the same manner. I've had no issues with this as yet, though I've only been using it for a few weeks. Long term durability is still in question for the integrated support/whipping that I'm using right now.

    I'm still not sure I like the ring buckle system as yet. I'm trying to find a technique for hanging/tying it up that is as easy to undo as it is to tie. I'm currently thinking the ringbuckles with the webbing going completely through both rings, then putting a loop through the locking ring so that I can simply yank it and it will slip out. I would tie the loop around the tensioned support in a slipped overhand knot.

    I'll have to see if I can find the cord for my camera and get some pictures posted at some time to better show what I'm explaining. Having two people in the hammock wasn't the most comfortable of conditions, but it could be done pretty well if you're both on your side.

    You were joking right? 50 lb load limit? There is now way in the world I'm gonna try that tarp tensioner. It's already a big enough risk to run Dual Ring but that? Na, I trust the knots. I do use ring, btw.

    I'm sure he meant using the figure-9's for hanging the tarp seperately, not the hammock itself. That's what I use them for, and they work quite nicely.

    Okay, that makes sense. Do they tear into the rope at all?

    Not that I've seen, and I've been using them for a while now. Including two trips with 30+ mph static winds. In fact on one trip (remember this one, Tim?) the wind pulled two of my MSR Groundhog stakes out of the solid-frozen ground...no damage to my tarp or tie-out cords though. As far as I can tell, the 9's didn't even slip.

    In my limited experience with them, no.

    I use the plastic line tensioners from REI with my tarp and they work great. Those metal one's have a fairly sharp looking point. I was concerned about it poking a hole in my netting or hammock when stuffed in the sack.

    They aren't that sharp. Also, I agree with the above posts that the 9's aren't really abrasive to the rope.

    Use a strong biner on the end of the support rope, leave the webbing in the buckles. Loop the support rope with the biner around the tree as many times as necessary to take up the slack. Clip the biner, adjust at the ring as necessary. To undo, just unclip the biner, and roll it all up into your preferred snakeskin, bishop bag, ... Really easy.
