The tensionless hitch gains its name from the use of a figure 8 loop at one end that is clipped to the standing end with no tension. It preserves most of the rope’s breaking strain. It is designed to bear a lot of load, that is, humans. It does not pose a significant stress on the rope. The anchor for the rope, it could be a tree, pipe or post, should be very secure as the knot applies rotational forces on it. It finds mention in The Ashley Book of Knots.
How to Tie a Tensionless Hitch
For this, you need to make 4-5 turns around a post. Hence, ensure you have enough length of rope.
- The diameter of the anchor should be at least 8 times that of the rope.
- The number of turns around the anchor should be increased if it is polished and smooth.
- Any corner or edge on the anchor reduces the strength of the rope in proportion to the sharpness of the bend.
- The figure 8 loop is strictly a safety mechanism that is attached to the standing part with a carabiner.
- For additional safety, you can tie an overhand knot around the standing part before the final turn around the anchor.
- Instead of the carabiner, you can use a figure 8 follow through.
