What is the knot efficiency of a tensionless hitch?

The knot efficiency of a tensionless hitch is considered to be 100%. This means that the hitch maintains the full strength of the rope when under load, as it does not significantly alter the rope's characteristics compared to other knots that may cause some degree of strength loss.

A tensionless hitch relies on the friction created by the rope against an anchor point, allowing the load to be distributed evenly without compromising the integrity of the rope itself. This property is particularly beneficial in rescue and climbing scenarios where maintaining maximum strength is critical.

In contrast, other knots can introduce complexities and reduce the operational strength of the rope due to the nature of the knot itself, which can create stress concentrations or friction points that weaken the rope, resulting in lower efficiencies. The efficiency of a knot should always be considered when planning any rescue or climbing operation to ensure safety and reliability.
