I just joined today after lurking for a couple of weeks, and my head is spinning with all the information on webbing, buckles, ridgelines and two-way zippers. I don't even have a hammock yet! My husband and I have been talking about using hammocks to backpack in the White Mtns. (NH), where it's difficult to find a comfortable tenting spot. My other concern, besides making sleeping easier, is conserving weight. We currently have a 5# two-person tent, and I can see that hammocking for two may not beat that weight. But, I'm gathering estimates of the weights of the items we'd need to start hanging.
Which gets to my question: are any of you hanging two (or more) hammocks under one tarp, and how large is that tarp? How much does it weigh? Are you hanging the head-ends of the hammocks from the same tree, or the foot-ends?
