Hitch (knot)
 | This article needs additional citations for verification. (July 2023) |
A hitch is a type of knot used to secure a rope to an object or another rope. Hitches are used in a variety of situations, including climbing, sailing, and securing loads. They are classified based on their ability to be tightened or released, their resistance to slipping, and their strength. Some common types of hitch knots include the clove hitch, the timber hitch, and the round turn and two half-hitches.
Physical theory
[edit]A simple mathematical theory of hitches has been proposed by Bayman.[1] It predicts whether or not a hitch will hold, given the diameter of the post, the diameter of the rope, and the coefficient of friction between the post and the rope. The theory has been extended by Maddocks and Keller, including an approximate treatment of knots that are not hitches.[2] For example, they predict that a square knot will hold when the coefficient of friction of the rope with itself is greater than 0.24. These predictions are approximately correct when tested empirically.[3]

|---|---|---|
| Adjustable grip hitch | A simple and useful friction hitch which may easily be shifted up and down the rope while slack. | 
|
| Alternate ring hitching | A type of ringbolt hitching formed with a series of alternate left and right hitches made around a ring | 
|
| Anchor bend | A knot used for attaching a rope to a ring | 
|
| Bale sling hitch | A knot which traditionally uses a continuous loop of strap to form a cow hitch around an object in order to hoist or lower it. | 
|
| Barrel hitch | The "barrel hitch" and "barrel sling," named for their use in hoisting cargo aboard ships, are a simple yet effective way to suspend an object. | 
|

| Garda hitch | A ratcheting knot used to disallow dual direction rope travel. | 
|
| Gripping sailor's hitch | A secure, jam-proof hitch used to tie one rope to another, or a rope to a pole, boom, spar, etc., when the pull is lengthwise along the object. |

|
| Hitching tie | A simple knot used to tie off stuff sacks that allows quick access as it unties quickly. | 
|
| Icicle hitch | A knot for connecting to a post when weight is applied to an end running parallel to the post in a specific direction. |

|
| Knute hitch | A knot used to attach a lanyard of small stuff to a marlingspike or other tool. | |
| Magnus hitch | A knot used to attach a rope to a rod, pole, or other rope. (See also Rolling hitch) | 
|
| Marline Hitching | A knot used to attach a rope to a cylindrical object. Similar in appearance to the Chain Hitch, but a succession of overhand knots. |
