Level for me. Haven't had trouble sliding.
Level for me. Haven't had trouble sliding.
I hang the foot end a bit higher, originally because of the sliding issue.
Another benefit: I have been sleeping with my feet raised for years, to reduce swelling in my legs, mostly due to being severely overweight. As I have approached the 200's (Going Down), that is less of a problem, but I still benefit from the slightly raised legs.
I usually have my foot end a couple of inches higher. I like to be more toward the head end of the hammock and having the feet higher seems to help keep me there.
I thought I was wrong once, turns out I was wrong about that.
For me feet end higher I tend to wiggle toward the foot end if I don't hang it higher. I also figure my center of mass is going to go to the lowest part anyway so I may as well account for that.

How about a little science?
I always bought into the idea that our center of gravity (CG) is generally in the upper half of our body. If true, you would hang the foot end of the hammock a little high so that when your CG slid to the low point of the hammock curve you'd be centered. (Raising the foot moves the low point towards the head end).
However, the Physics Fact Book (http://hypertextbook.com/facts/2006/centerofmass.shtml) says:
-A person's center of mass is slightly below his/her belly button, which is nearly the geometric center of a person.
-Males and females have different centers of mass- females' centers of mass are lower than those of males.
-The average ratio of center of mass to height in females is approximately 0.543 and the average ratio of center of mass to height in males is approximately 0.560.
So in reality our CG is just a little above our standing center point. Hanging the foot end higher still makes sense but it probably doesn't need to be much higher. If I'm feeling ambitious I might try the math to figure out just how much higher.

I don't know how to vote. If i am in the BB, then my feet are a little higher. If i am in the bridge, then i am level.
Experts are the ones who think they know everything. Geniuses are the ones who know they don't.
You need seek no rocky summit, for these high places are within you.
Feet a few inches higher in the BB as when i have my UQ on if i slide down a little my feet pop the footbox out of the UQ....! plus after a good hike its good to elevate your feet to rest!

I haven't paid very close attention to this, but I seem to lay relatively level when resting. When I had a foot injury I did keep my feet elevated though.
Using a vector graphics program (TouchDraw for iPad) I modeled the difference btw flat and foot end high. The person is modeled close to scale with the belly button showing approximate center of gravity. Small red triangle shows the low point of each hammock. Raising the foot moved the low point about 4-5" towards the head end.
This model isn't the most scientific but it was a fun exercise.

On the "scientific-ness" of the poll - bad news: To give as accurate a picture as possible, the poll should be given to a random sampling of hangers. As it's being done, all the samples are volunteer, thus negating any randomness. That is, instead of getting a random sample, no matter how large, you are only getting people who want to participate. Thus the poll will not be a truly accurate representation of levelness in hammock users.
But who cares? It's fun anyway!
