A question about the angles

Force on your suspension becomes exponentially greater the closer to horizontal it gets. At 30 degrees, each side has a load approximately equal to your bodyweight. The reason to not go super taut on suspension isn't just for the sake of your suspension and ridgeline but also to avoid putting that much force on the trees. Not only can this increase the likelihood and severity of damage to the trees, in some areas with very shallow soil, you also increase the chances of that tree toppling especially if conditions get windy.

At 15 degrees from horizontal, the force on each side is almost twice your weight. At 10 degrees, it is almost triple. At 5 degrees it is 5.75x your body weight on each side. For a 180 lb human in a hammock, that's 180lb pulling on each tree at 30 degrees, 348 lbs on each tree at 15 degrees, and over 1000 lbs of force per tree at 5 degrees.

There is no good reason for having excessively taut suspension. A ridgeline should be used to maintain a consistent sag to a hammock regardless of variation in suspension angle, and a 30 degree angle will minimize strain on all parts of the hammock while still keeping the ridgeline taut.

It's important it you don't have to be 100% accurate, I just eyeball it.

Best way to check is the finger gun, thumb up and parallel to the tree, index finger pointed to the hammock. If your suspension goes from the tip of your thumb to the tip of your index finger you are good

I've snapped ridgelines from going too tight.

When the gap between trees is very wide it can be hard to get the straps high enough. This creates a tonne of tension when you get in. Do your best to get the straps higher and have a good angle. 30° is not critical by any means, and even 20° can be fine, adjust to what you find comfortable but keep the tension factor in mind.

Hang at 30 degree and have a ridgeline that basically tells you if you are too slack or too tight. This is hammock 101. I disagree with people who say tomato; tomahto—hang however taut you wish.

Every hammock model may hang slightly different. And every hammock sleeper may prefer it slightly different.

With time and experience, you’ll get a handle on what works for you. Don’t be afraid to play around with the angles a little to find your sweet spot.
