The Anatomy of Rope
3 parts of a knotted rope End Standing part
The inactive length of the rope Bight
Between working end and standing part
Stopper Knots
Used to keep rope from slipping out a hole or a knot
Overhand Knot Simplest and smallest of all knots Used in small cords and twine It jams and is hard to untie
How to Tie: Make an overhand loop Pass end under and up through
the loop
Stopper Knots (cont’d)
Used to keep rope from slipping out a hole or a knot
Figure Eight Knot Larger, stronger than an overhand knot Does not injure rope fibers
How to Tie: Make an underhand loop Bring end around and over the
standing part Pass the end under and up through the loop
Binding Knots
Used to tie one or more objects together Square Knot
Good temporary knot Unties easily when either free end is pulled
How to Tie: Pass the left end over and under the right Curve the left end towards the right Cross the right end over and under the left Remember: “Left over right, right over left”
Loop Knots
When security comes first Bowline
“King of Knots” Never jams or slips
How to Tie: Overhand loop with end held toward you Pass the end up through the loop, then up behind the standing
part Then down through the loop again
Hitches
Temporary fastenings that untie readily Half hitch
Used for fastening to an object for a right-angle pull Two Half hitches
Just two half hitches (it’s that easy!) Quite secure Used for mooring and on fishing hooks
How to Tie: Pass the end of the rope around the object Tie an overhand knot to the standing part Repeat once more above the first knot
Hitches (cont’d)
Temporary fastenings that untie readily Clove hitch
The “general utility” hitch Used to fasten a rope around a post or stake Best used at the middle of a rope
How to Tie: Make a turn with the rope around the object and over itself Take a second turn around the object Pull the end up under the second turn so it lies between the
rope and object
Bends
To tie two ropes togetherShould be used on ropes of same size and texture
Sheet Bend To join light and medium ropes Unties easily Does not injure rope fibers Not best for heavier ropes
How to Tie: Make an overhand loop with the end of one rope Pass the end of the other rope through the loop Pass that end up behind its standing part And down through the loop again
Fisherman’s Knot
To tie two ropes together Joins small rope, twine, and fishing line
Very strong and easy to undo Can be used to form a loop in one strand of rope
How to Tie: Lay the two ends together in opposite directions Tie an overhand knot in the end of each around the standing
part of the other
