I am a righter of wrongs, I hang down from above, I am coiled like a snake, I am tight as a glove. What am I?

Question

Like a snake of twisted birth,
Coiled ut not to strike.
Hurled at men caught in the brine,
Or linked up to a spike.
Stops the horse that seeks to roam,
Or holds a sheet out on the foam.
What is it?

Answer 1

The answer is a noose
