Mason Line for Ridgeline
Anybody know about how much weight is borne by a hammock ridgeline under optimal hang conditions (30* angle)? I know it's not as much as I weigh, but I'm wondering if it would be less than half my weight? The reason I ask is because I'm hoping to use braided mason line for it. I haven't had the stuff fail on me before, but wanted to see if anybody's given this a try.
Mason's line is great for non-load bearing applications only. Max load of under 50lbs.
Actually a structural ridgeline takes a good bit of load. I know of several folks that have had a 300 pound test ridge break. One report I was given by a customer was of his wife getting whipped in the face when the ridgeline broke while she was in the hammock. 450-500 pound test is the lowest I would recommend. We use 1000 pound test dynaglide for our adjustable ridgeline. Don't think that mason line, even if it did not stretch like crazy would be a good choice.
No kidding! Is a structural ridgeline the kind with the whoopie slings threaded through a locked brummel fixed eye at both ends?

Structural ridges can be fixed length or made like a Whoopie sling for adjustment of the sag. They would usually connect at each hammock end onto the primary suspension. A key component to structural ridge is that it does not stretch as the stretch would change the lay/sag of the hammock as it stretches.
An example of a non structural ridgeline could be one that made out of shock cord and be designed to hang an organize, headlamp/lantern, glasses what ever off of. It could be any number of materials but is not used to form and maintain the shape of the hammock like a structural ridge would.
I use braided mason line as a ridge line. Hang your hammock properly at 25 to 30 deg and the stress on the ridgeline is quite light. I can reach up and twist the line through about 90 degrees without difficulty. Use a shallow angle and you load up the ridgeline enormously, in which case you would need dyneema or similar. So far I have not had a ridge line break, but I am really careful about the hang angleAttached is a chart of the stresses involved. Here is a link to a vid by Warbonnet guy showing just how you should hang your hammock.
