Where it fails
Watch out
Both hitches must turn the same way. Opposite turns make a cow hitch, and it slips.
- Leave a tail. Four to six inches so it cannot pull through.
- Heavy or jerking load? Take one full wrap round the post first. The wrap takes the strain.

Four knots cover nearly every job on a homestead, a campsite, or a truck. The rest are on the knots page, picked by the job.
Questions this answers
Tap a question for the short answer.
How do you tie two half hitches?
Pass the end over the rail and down behind it. Bring it across the front of the standing line, round behind, and down over itself: that is one half hitch. Make a second one below it, turning the same way. Slide both up to the rail and pull tight. Leave a four to six inch tail.
What are two half hitches used for?
Tying a rope to a post, stake, rail or ring, including square or slick ones where a clove hitch slips, and the fixed end of a tarp ridgeline. It ties and unties under tension, which most knots will not.
What is a round turn and two half hitches?
The same knot with one full wrap round the post taken first. The wrap takes the strain, so it is the version for a heavy or jerking load, a boat on a line, or a tarp in wind.
Which knot ties to a post under tension?
Two half hitches. You can tie it while the standing line is already pulling and untie it the same way. Take a round turn first if the load is heavy.
How do you back up a clove hitch or bowline?
With half hitches from the tail. For a clove hitch that might roll loose, two half hitches with the tail round the standing line, snug to the hitch. For a bowline that will sit slack, one or two half hitches with the tail round the loop leg, tight to the knot.
