I am trying to figure out what kind and how much cord I need for my hammock. I have a GTP Nano 7, which is 9' long, and I have a ridgeline on it that is 8' long. My tarp is 9' long. I am trying to find appropriate cord for the hammock, but I am uncertain how long I should make the lines. To connect to the trees, I am using some straps with a Marlin Spike hitch, and I am using a trucker's hitch on the cord to suspend it.
What I would like to know is:
1) How long should the cords be on each side of the hammock?
2) What strength of cord should I use (I am in Europe, and everything I see in shops has the weight rating listed in kN, and I have no idea what to do with that).
I am also interested in the length people use for the ridgeline for the tarp.
I appreciate any help!
