The Bowline on the Bight is a versatile knot that forms two fixed loops in the middle of a rope, ideal for climbing, caving, and rescue operations. It is commonly used when neither end of the rope is accessible, providing secure footholds or emergency seating. The knot is easy to untie after strain and can support multiple people in hoisting scenarios. In caving, it's known as the 'Y-Hang' for free-hang descents with load distribution across two anchor points.
