What describes a Dynamic Belay System in terms of points of contact?

• A. Two points of contact: the harness and the belay anchor point.
• B. Three points of contact: the harness, the belay anchor point, and the belayer.
• C. One point only.
• D. Four points including rope.

Answer: (B)

The idea being tested is how a dynamic belay system is structured in terms of what remains in contact during a catch. In a dynamic belay, three points of contact keep the system connected and able to absorb shock: the climber’s harness (where the rope attaches to the climber), the belay anchor point at the top (where the rope is redirected and fixed to a solid point), and the belayer (the person managing the rope with a belay device). This setup allows energy from a fall to be managed through the climber’s harness, the fixed top anchor, and the controlled action of the belayer, reducing peak forces through rope stretch and controlled deceleration. Having only one point would offer little control or redundancy, while four points would introduce an extra contact that isn’t part of the standard three-way load path.
