How do you determine load distribution when rigging multiple anchors?

• A. Distribute load equally regardless of geometry.
• B. Ignore geometry and rely on rope strength.
• C. Evaluate the geometry, test load paths, and ensure each anchor shares a portion of the total load.
• D. Only attach to the strongest anchor.

Answer: (C)

When rigging multiple anchors, the key concept is how the forces travel through the system and how the load is shared. The geometry of the setup—where the anchors sit, the directions the lines run, and the angles between those lines—defines the load path. By evaluating that geometry and imagining how the load would path through the anchors, you can configure the rig so that the total load is distributed among the anchors rather than being carried by a single point. This often involves creating an equalized or partially equalized arrangement that ties the anchors to a common point and directs force through all of them, while keeping the angles in a range that encourages sharing rather than concentration. This reduces risk and adds redundancy. Relying on rope strength alone ignores how forces actually move through the anchors, and concentrating load on the strongest anchor creates a single point of failure.
