Follow the path. Understand the limits.
Schematic rope paths do not inspect or certify your knot. Verify tying with an instructor. Do not approve climbing, rescue, suspension, towing or lifting with this app. The strength calculation is a hypothetical multiplier, not a prescribed retention value or working-load limit.
Model details & unit conventions ↗Tie a figure-eight stopper knot in four steps, recognise a correct one by its two lobes, and compare it with an overhand stopper. Practice only.
Tie a round turn and two half hitches around a fixed post or tree at camp, check the knot before you rely on it, and untie it after load.
Why published knot strength percentages disagree, why breaking strength is not a working load, and what the Knot bench retention figure does.
Guyline cord materials compared: nylon, polyester and UHMWPE on stretch, knot creep and friction heat, plus construction, diameter and reflective tracers.
Work out tarp guyline length from ridge height and stake distance, then add a ridgeline allowance for tree spacing, trunk wraps and knots.
