Quick Answer
Paracord stretches when wet, and this can affect its use as a reliable cordage solution, especially in critical applications like securing gear or creating life-saving systems.
Paracord’s Hydrostatic Properties
Paracord, like many other cordages, experiences significant stretching due to hydrostatic pressure when submerged in water. This effect is more pronounced in the 550 type paracord, which has a relatively high tensile strength and a braided construction that can absorb water. When wet, a 10-foot length of paracord can stretch up to 30% of its original length, making it less suitable for applications that require a stable and consistent tension.
Practical Considerations for Wet Paracord
When working with paracord in wet conditions, it’s essential to take into account its increased stretchability. If you’re creating a paracord system, such as a makeshift tow line or a secure attachment point, consider using a backup or redundant system. For example, you can use a secondary cord or a more stable material like webbing or rope to supplement the paracord. Additionally, always inspect the paracord for signs of water damage or wear before relying on it in a critical situation.
Preparing Paracord for Wet Conditions
To minimize the effects of wet conditions on paracord, it’s crucial to prepare it properly. Before submerging the paracord in water, make sure it’s dry and free of any knots or tangles. You can also apply a waterproofing treatment to the paracord to help protect it from water damage. However, keep in mind that no treatment can completely eliminate the effects of hydrostatic pressure, and it’s always better to err on the side of caution when working with paracord in wet conditions.
