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.


Constrictor Knot Part 1 Start

Start with a turn around the object you are tying a Constrictor on.


Constrictor Knot Part 2

Continue around the object  like you are making a Clove Hitch.


Constrictor Knot Part 3

Tie a single overhand knot that’s under and held by the crossing coil.


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.
