What kind of hookup is used on the participant?

• A. A standard figure-eight knot
• B. A Bowline on a Bight with a double over-hand safety knot connected at the back belay loop and the back chest loop with two supersafe carabiners
• C. Clove hitch
• D. Reever knot

Answer: (B)

The idea being tested is using a multi-point, redundant hookup to keep a participant securely attached. A Bowline on a Bight creates two fixed loops from a single rope, which are then clipped to with two carabiners. Adding a double overhand safety knot helps prevent those loops from slipping or coming undone under load, giving you a secure backup. Connecting these two loops to both the back belay loop and the back chest loop distributes the load and provides two separate attachment points, so if one point or carabiner were to fail or gate-open, the other still holds. Using two locking carabiners (supersafe) further protects against accidental opening and reduces the chance of cross-loading. This setup emphasizes safety and redundancy, which is essential for participant hookups in adventure settings.

The other options aren’t as reliable for this purpose: a standard figure-eight knot is great for tying into a rope but doesn’t give two dedicated attachment points or the redundancy required for a harness hookup; a clove hitch can slip or shift under movement and load changes; and the Reever knot isn’t a standard, proven choice for secure harness connections and lacks the built-in redundancy of this setup.
