I know there are some people here with math backgrounds. How do you guys calculate this?
If you take the standard ratio of ridgeline:hammock length of 83%, the distance of the lowest point of the hammock to the ridgeline length should be definable as either a function of ridgeline length or hammock length. I don't think the shape of the hammock when loaded is a catenary curve as you are laying diagonally and at least attempting to lay flat, right? I would guess that the shape when sitting is closer to an isosceles trapezoid with the bottom length being the width of your backside and the shape when laying is an isosceles trapezoid with a bottom length equal to your diagonal lay length (plus some fudge for not laying completely flat.)
Among other things, I'm trying to back into strap height and I'm getting significantly different results than dejoha's calculator (~56in vs ~72in for a 89.5in ridgeline on a 15 foot tree span) I'm thinking that this is the most likely place I might be screwing up since everything else should be basic trig functions.
I'm calculating more things than the calculator provides, so that's why I'm doing it on my own.
