Which configuration is used to achieve a secure anchor with minimal tension on the knot?

The tensionless hitch is specifically designed to create a secure anchor point while minimizing the tension exerted on the knot itself. This configuration allows the rope to bear the load without putting significant stress on the knot, which can be advantageous in situations where preserving the integrity and functionality of the rope is critical.

In a tensionless hitch, the rope wraps around an anchor point and creates friction, effectively anchoring it without compressing it tightly. This approach helps distribute the load more evenly, reducing the risk of damaging the rope fibers or the knot under heavy loads. It is often utilized in rescue scenarios to maintain the strength of the anchor and the rope used in the operation.

The other configurations serve different purposes. An anchor loop provides a method of connecting to a fixed point or other gear but may not reduce tension on the knot as effectively. The clove hitch is useful for securing objects or creating temporary anchors; however, it does not minimize tension as effectively as a tensionless hitch. Lastly, the double figure eight is designed for situations that require secure knots and backup options but does not focus on minimizing tension in the same way as the tensionless hitch does.
