The Garda Hitch is one of many ways folks have used to suspend their hammock. It was adopted from climbers who use this as a simple “pulley/ratcheting” system to haul gear up and not slip.
Why Use The Garda Hitch
- Works with fairly slippery line such as Amsteel
- Can be used/attached close to the hammock, creating a drip point
- Fairly easy to tie (simple wraps)
- Adjusts quickly and easily
- Holds fast and doesn’t slip (for details, see test results below)
- Easy to take apart/dismantle
The Garda Hitch isn’t without its distractors, however. Some folks have worried about the pinching process weakening the cord over time, leading to cord failure.
To play devils advocate, any suspension system for a hammock is prone to wear over time, so no matter what technique or system you use should aways be inspected for wear and abuse. Those who hang often may need to replace their suspension every season. Climbers, for example, are especially conscious about wear and systematically replace ropes just to play it safe.
There isn’t a lot of documentation on breaking strength and load strain using the Garda Hitch. In truth, I don’t think it was ever envisioned that this hitch would be used to hold human weight. I asked a buddy of mine, David of Canny Designs (creator of the Loop Alien) if he would mind using his tools to do a fail test on the Garda Hitch.
The Bottom Line
The Garda Hitch held fast and worked well for a load under 400 lbs (181.4 kg) before slipping. Above this limit, the Amsteel began compressing and stretching, and slowly slipping, but it never failed. Failure occurred with the aluminum rings!
Recommendations
In certain circumstances, the Garda Hitch works well for hammocks. I would recommend it for hangers less than 250 lbs (113.4 kg) who are interested in this quick-adjusting system.
Here are the results:
The rings were anchored with a looped length of 1/8 amsteel (back woven fig 8 knot). The hammock side was 7/64 Amsteel. Rings were seamless aluminum SMC descender rings.The black mark on the rope in image 7 is from a marker. When I ended the test, that mark was exiting the rings all together but the system was still holding some tension.In images 5 and 10 you can see how the rings became misaligned allowing the rope to slip. Notice how the outer weave of the Amsteel was bunched up and the tail entry point.7/64 Amsteel started intermittently slipping around 2000n (449 lbs).Max 2608n (586 lbs) at this point the rings had separated enough that the rope just continued to slowly slip.Rope stretches on the 1st bend of the hammock side rope (see image10) some broken fibers can be seen.
