Constrictor Knot

Constrictor Knot

The Constrictor Knot is a knot that should be in every boaters skill set.  This knot can be used for emergency repairs and quick whipping on the end of a line to keep the line from unraveling until a permanent repair can be made.  The Double Constrictor is a variation that clamps a bit harder.  The Constrictor is a binding knot that is difficult to untie, many times it needs to be cut off.  The Constrictor can be tied easily and quickly either right or left handed.  A Single Constrictor is a variation of the Clove Hitch with a single overhand knot tucked from the outside  to the center under the crossing wrap section.

The Constrictor Knot can crush fragile objects.

Finished Constrictor Knot Part


Move the two turns close together and pull the knot down snug and you have a knot that will bind down onto what it is tied to.

Tie the ends around a marlinspike, screwdriver or other object to help you apply more tension to the knot without hurting your fingers.

Finished Single Constrictor Knot.

The Constrictor can be used as a quick whipping for the ends of lines (I prefer the Double Constrictor as temporary whipping on lines that will be used). I use a Constrictor Knot when I need temporary whipping when braiding three strand line or other times I need a quick secure binding temporary knot, I use a Double Constrictor if the knot needs to be permanent.
