The taut-line hitch is type of knot, being a modified version of the two half hitches. Template:Knot-details
Uses
It is useful for tensioning lines where the tension may need to be periodically readjusted. It is typically used to secure loads on vehicles, and to secure tent lines.
The taut-line hitch does not work well with some modern synthetic lines that are excessively slick or which do not knot well, though it can usually be made to function by tying more than the basic three half-hitches.
The taut-line hitch is used in arboriculture to climb trees. The climber grips the tree with his legs, thrusts his pelvis upwards and pushes the knot up the rope. To decend the climber merely has to pull downwards on the knot.
Tying the taut-line hitch

- Pass the line from the load, loop it around the anchor, and take the free end and loop it around in a half-hitch; that is, loop it around the standing line and pass it through the loop formed.
- Then pass it through the loop again in the same direction, so that there are two passes of the line through the loop.
- Then tie another half-hitch on top of this, in the opposite direction; that is, pass the free end around the standing line above the hitch just tied, but going around in the direction opposite to the previous half-hitch. Then pass it through the loop formed and tighten.
The taut-line hitch is easily adjusted. To tighten the standing line, grasp the standing line with one hand just on the anchor side of the hitch, and pull against the load; then grasp the hitch with the other hand and slide it towards the load. Or to loosen, slide it toward the anchor. The knot can be repeatedly adjusted as needed.
