A bivouac hammock weighs only a few hundred grams. Robustness is not its strong point. Badly used, it deteriorates very quickly. With some precautions, it can nevertheless be continued for a long time.
In the middle of the jungle, a band of adventurers cut its way to the machete. After several days of progression, they are in a remote and very wild area. In the evening they climb their bivouac. Sliding into his hammock, Indi in an instant finds himself on the ground. His poorly maintained hammock just broke. The possibility of sleeping on the ground does not enchant it, and when one knows the kind of fauna sometimes teeming and unfriendly that walks on the soil of a tropical or equatorial forest, one understands it.
– Euhh Kiki, we took a spare hammock?
– Well no !
– You gotta fix it, is there glue?
– No more…
– Ouinnnnn !!!!
– Calm down ! We will make an emergency hammock with your tarpaulin.
– Phew, saved thanks Kiki!
To avoid this difficult scenario, you must try to spare your hammock. A best nylon hammock, when it has a snag, tears in the same way that a stocking is made. Here are some precautions to take:
- Avoid getting into your hammock with a blunt object (shoes, frontal, Swiss Army knife, sticks). By sleeping on a hard object this one will exert an overpressure on the already very taut fabric.
- Do not leave sand at the bottom of his hammock, it would act like an abrasive on the stretched canvas
- Do not overtighten the hammock. According to the triangle of forces, the more the hammock is stretched and the greater the force exerted on the hangers is once the hammock is loaded. The weight to be supported can reach several times the weight of the user. If your fastening rope is at an angle of 30 ° to the horizontal, the weight of the user will be applied on each side. If this angle is only 10 ° with respect to the horizontal, (it must be strained!), It is practically 3 times the weight of the sleeper that applies to each point of attachment!
- Untangling the lines. If the lines are tangled, the weight will not be well distributed. Some will bear many more constraints than others.
- As soon as the canvas has a wear or tear, repair (see repair section)
- Avoid the web or lines hitting the ground or a branch. With the weight of the user it would be holed (cut off for the lines) very quickly. If the hammock inevitably touches something you have to put a piece of cloth or plastic between the hammock and the relief in contact.
How to repair your hammock?
You must know that a hammock can very quickly tear itself apart, but when a hammock is broken, it can be easily repaired. Even when your hammock completely splits in its width to form two distinct parts in a journey, with a little neoprene glue you are able to restore it and fulfill its function until the end of the journey. When the hammock tears in this way, it is enough to put neoprene glue on a strip of 2 cm width along the tear on each part of the hammock and to overlap the 2 bands. A reinforcement piece can also be bonded to the critical areas (in the center of the tear and on the edges). When you spot a snag, cut a piece of cloth, coat it with neoprene glue, coat the area around the snag and stick the patch. A neoprene glue (soft) is essential because it will have to withstand the deformations of the fabric.
If a line breaks, repeating the line is tedious. It is possible to make a connection node with another end of cord. The length of the entire triangle of strands must then be readjusted to prevent the repaired strand from being of the same length.
The ultimate solution if you can not sleep on the ground (equatorial forest) is to make a rescue hammock with its cover. A simple and fast technique is to grip each end of the tarpaulin by tying it with the tie rope (like a candy). It’s really troubleshooting (that said, we saw people who lived in this type of hammock for weeks).
