Why using three trees ? Since you're already using spreader bars at both ends, i guess it's not for structural reasons. Is it for stability ? How does this hammock behave when only one person lays on one side ? What about a hammock with only two anchor points ? Would it be necessary to hop in it and get off it at the same time as your partner ?
I went hammock camping for two weeks with my girlfriend and we really miss sleeping together, so this is what i'm planning to make, and i'm wondering if it is possible or a total aburdity (don't laugh at my MSPaint skills) :
[Edit:] Oops, sorry, i read the entire first post and had my question answered.
Still, can the central rope be adjustable as i planned ? Or is it another absurdity ?
Maybe with an adjustable central rope, one can warn the other he or she's getting off the hammock, loose the central rope and let the other person rest in the middle of the hammock, effectively avoiding tilting while still using two trees ?
We are both about the same weight.
Nice drawings! I think you ask some good questions. Yes, it is all about stability and ease of use. But I ended up asking the question from the opposite perspective.
"Since I know I will need three trees, do I really need spreader bars at the head end?"
I think the short answer is NO.
"Can the central rope be adjustable"
Good idea. I ended up using a section about 12"-15" of very thick shock cord added to the end of the cord. This allowed some movement and flex. To me it was a solution that could be set once, rather than adjustable during use. I try to simplify the design if there is an opportunity to do it, so that was the answer that was working for me.
Here is an important finding regarding the central support rope and the flat lay of a double bridge. Allow the central rope to exit at the level of the knees and continue to the apex of the foot triangle free from the fabric bed, and in a similar way from above the shoulders. This gives better results than allowing the central support to form a simple arc. It will allow you to keep the lowered foot for flat sleeping- like a bridge hammock.
