Well a self rigged one basicly, I didnt even know that hennesy hammocks exsisted
they look pretty sweet I had to google them, my setup is basicly the same jsut done with in home pieced together stuff.
I have a 5 person hand swen jamican style hammock, its wider than it is long and you sleep in it either longway with one person on each end or shoulder to shoulder with your legs crossed and it holds up your heads.
I like it alot better than most hammocks cause 1, its more like a net, so very small stiching. 2 it can sleep 3 people very comfortably, 3 its really light and made out of some nylon like material and nearly impossible to tear and finaly b/c I can bnungee a hammock to a tree (no hammer or spike required), run a slack line above and drape a tarp ( if raining, or a mosquito net if needed).
The things to rember about this is that 1, you can get SOAKED from dew, and if you don't protect your ground side or exposed side of the hammock you will get COLD. I don't recommend this for unseasoned people or if your going anywhere below freezing.
