For those of you who consider 9.2 oz of smart phone an essential element of your trappin's, there are a gob of angle apps. Doesn't solve the math but it will tell you when you have 30 degrees.
what in heaven's name are you talking about? does this have anything to do with hammocks?
yes.

Yes,it is relavant but its still easier to just hang the hammock and adjust to suit comfort
There's a coincidence of the recommended 3Odegree hang angle, the recommended length of the hung hammock compared to the total length, and natural optimal packing, as in the hexagonal honeycomb chamber.
I was interested in a possible mathematical basis an engineer or biologist might know.
Since we're all different shapes, YMMV, but it is surprising that for most the 30 degree and 5/6 rule is so close to optimal.
When calculating the tension in the suspension, 30° makes the maths very easy and mean each rope experience a force equal to the weight is the hanger.

Would the maths be simpler if you consider the cat curve to be a section of a larger circle and the straight line length the cord intersecting the larger circle with a tangential angle of 30°? Give me a few minutes at work (when I get a free period tomorrow) and I'll go through this theory. If a none has more free time or is more polished on circle geometry and cords.

I'd wager the 30° angle is due to the simple weight call it leads to.
At 30° the tension in EACH suspension arm is euqal to the weight in the hammock, a 200lbs hammock means each arm of the suspension experience a tension of 200lbs.

Found this Thread to be quite interesting. After reading all the math and looking at all the calculations, I think I like Chems answer for the 83%. I think the end goal is the angle created between the end of the hammock and the "flat bed" one creates once in the hammock.
I think by having a ridgeline that is 5/6 the hammock length you get a flat bed that is up to 5/6 the hammocks length with the extra 1/6 of material allowing for the angle down to that bed while not putting so much stress as to overcome the "flat lay". Won't that angle always be the same regardless of "bed" length up until you surpass ridgeline length?
Sorry I loved this thread and had to throw in my 2 cents
