A simple knot that will hold under a load, the buntline hitch can be rapidly and easily passed through a ring or around a bar or spar. By splitting its back, it can be loosened easily. You can use it for attaching a Genoa sheet to the clew of a sail or a halyard to a shackle.
A. To tie the buntline hitch, take the bitter end behind and out through a ring. Come to the right of the working part to form a “U” around the working part, holding it in place with your index finger and thumb.
B. Bring the bitter end around and in front of the working part, behind the right limb of the loop and down through the newly formed loop.
C. Shape the knot, making sure it is a tight clove hitch on the working part, then cinch down tightly. The hitch will slide up toward the ring and tighten on the ring.
D. Finished hitch
