What knot is used to connect two ends of a handline?

The Bowline is a preferred knot for connecting two ends of a handline because it forms a fixed loop at the end of the rope, which can be crucial when creating a secure connection that can bear weight or withstand tension. This knot is beneficial as it is easy to untie even after having been under load, making it practical for situations where ropes may need to be readjusted frequently.

While other knots such as the Square Knot do connect two lengths of rope, they are not as effective in maintaining their integrity under varying loads, which is often necessary in line work. The Clove Hitch is primarily used to secure a rope to a post or another object rather than joining two ends. A Half Hitch, though useful in tying or securing lines, is not effective on its own for connecting two separate lengths of rope, particularly in applications where reliability is essential.
