Quick Answer
Paracord is strong enough for shelter lashings, but like any cordage, its strength depends on the specific type, condition, and technique used.
Choosing the Right Paracord
When selecting paracord for shelter lashings, look for Type III or Type VII, which have a minimum breaking strength of 550 pounds and 850 pounds, respectively. These types are more suitable for load-bearing applications like lashings. Avoid using Type I or Type II, which have lower breaking strengths of 300 and 450 pounds, respectively.
Tying Effective Lashings
To create strong lashings, use a secure knot like the Bowline or the Alpine Butterfly. The Bowline is ideal for vertical lashings, while the Alpine Butterfly is best for horizontal lashings. When tying lashings, overlap the cordage by at least 6 inches to ensure a strong, stable connection. For added security, use a turnbuckle or a tensioning device to tighten the lashings. Aim to maintain a tension of about 10-20% of the cordage’s breaking strength.
Load-Bearing Considerations
When using paracord for shelter lashings, consider the load-bearing capacity of the structure. For a typical lean-to or debris hut, lashings should be able to withstand winds of up to 50-60 mph (80-97 km/h). To determine the required breaking strength, calculate the load in pounds per inch of lash length. For example, a 10-foot (3.05 meters) long lashing with a 6-inch (15.24 cm) overlap would require a minimum breaking strength of 5,000 pounds (22,680 Newtons) to withstand a 50 mph (80 km/h) wind.
