Quick Answer
A dynamic rope with a diameter between 7mm and 10mm works best for ridgeline knots due to its strength, durability, and flexibility.
Choosing the Right Rope
When selecting a rope for ridgeline knots, consider the environment and the type of shelter you will be building. A dynamic rope is ideal for camping and backpacking applications, as it has excellent shock-absorbing properties and can withstand the stress of wind and rain. Look for a rope with a diameter between 7mm and 10mm, which provides a good balance between strength and flexibility.
Key Rope Characteristics
A dynamic rope should have a minimum breaking strength of 22 kN (4,900 lbf) and a diameter that is not too large, as it may be difficult to work with in tight spaces. A rope with a diameter of 8mm or 9mm is often the best compromise between strength and ease of use. When selecting a rope, also consider its material – nylon or polyester are popular choices due to their durability and resistance to abrasion.
Setting Up the Ridgeline System
Once you have selected the right rope, you can set up the ridgeline system for your shelter. Start by attaching the ends of the rope to the anchors or trees, making sure to leave enough slack to accommodate the sag of the tarp. Next, tie a series of knots to secure the tarp to the ridgeline, using a combination of bowlines and prusiks to create a stable and secure attachment system.
