The water bowline is a type of knot designed for use in wet conditions where other knots may slip or jam.

Knot method of fastening or securing linear material, such as rope, by tying or interweaving

A knot is an intentional complication in cordage which may be useful or decorative. Practical knots may be classified as hitches, bends, splices, or knots. A hitch fastens a rope to another object; a bend unites two rope ends; a splice is a multi-strand bend or loop. A knot in the strictest sense serves as a stopper or knob at the end of a rope to keep that end from slipping through a grommet or eye. Knots have excited interest since ancient times for their practical uses, as well as their topological intricacy, studied in the area of mathematics known as knot theory.

Although similar in finished appearance to the double bowline, the water bowline is formed with a clove hitch as the loop in the standing part of the rope. This is similar to the double bowline, which puts the running end through a round turn. The additional friction from the clove hitch increases the security of this knot.

Double bowline

A double bowline is a type of loop knot. Instead of the single turn of the regular bowline, the double bowline uses a round turn. This forms a more secure loop than a standard bowline.

Clove hitch type of knot

The clove hitch is a type of knot. Along with the bowline and the sheet bend, it is often considered one of the most important knots and is commonly referred to as a Double Hitch. A clove hitch is two successive half-hitches around an object. It is most effectively used as a crossing knot. It can be used as a binding knot, but is not particularly secure in that role. A clove hitch made around the rope's own standing part is known as either two half-hitches or buntline hitch, depending on whether the turns of the clove hitch progress away from or towards the hitched object.

Although the name clove hitch is given by Falconer in his Dictionary of 1769, the knot is much older, having been tied in ratlines at least as early as the first quarter of the sixteenth century. This is shown in early sculpture and paintings. A round turn is taken with the ratline and then a hitch is added below. The forward end is always the first to be made fast.

The difference between two half hitches and the clove hitch is that the former, after a single turn around a spar, is made fast around its own standing part, while the latter is tied directly around the spar.

The Water Bowline can be tied very quickly by throwing two half hitches over the working end and then running the working end around the standing line and back through both half hitches. This is illustrated in the three pictures below.

Bowline type of knot

The bowline is an ancient and simple knot used to form a fixed "eye" at the end of a rope. It has the virtues of being both easy to tie and untie; most notably, it is easy to untie after being subjected to a load. The bowline is sometimes referred to as King of the knots because of its importance. Along with the sheet bend and the clove hitch, the bowline is often considered one of the most essential knots.

Constrictor knot

The constrictor knot is one of the most effective binding knots. Simple and secure, it is a harsh knot that can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn. The double constrictor knot is an even more robust variation that features two riding turns.

Truckers hitch hitch knot

The trucker's hitch is a compound knot commonly used for securing loads on trucks or trailers. This general arrangement, using loops and turns in the rope itself to form a crude block and tackle, has long been used to tension lines and is known by multiple names. Knot author Geoffrey Budworth claims the knot can be traced back to the days when carters and hawkers used horse-drawn conveyances to move their wares from place to place.

Taut-line hitch hitch knot

The taut-line hitch is an adjustable loop knot for use on lines under tension. It is useful when the length of a line will need to be periodically adjusted in order to maintain tension. It is made by tying a rolling hitch around the standing part after passing around an anchor object. Tension is maintained by sliding the hitch to adjust size of the loop, thus changing the effective length of the standing part without retying the knot.

Sheet bend bend knot

The sheet bend is a bend. It is practical for joining lines of different diameter or rigidity.

Running bowline

The running bowline is a knot consisting of a bowline looped around its own standing end to create a noose.

Half hitch overhand knot

The half hitch is a simple overhand knot, where the working end of a line is brought over and under the standing part. Insecure on its own, it is a valuable component of a wide variety of useful and reliable hitches, bends, and knots.

Triple bowline

The triple bowline knot is a variation of the bowline knot. The knot can be applied to emergency situations, such as mountain rescue.

Buntline hitch hitch knot

The buntline hitch is a knot used for attaching a rope to an object. It is formed by passing the working end around an object, then making a clove hitch around the rope's standing part, taking care that the turns of the clove hitch progress towards the object rather than away from it. Secure and easily tied, the buntline hitch will jam when subjected to extreme loads. Given the knot's propensity to jam, it is often made in slipped form.

The buntline hitch, when bent to a yard, makes a more secure knot than two half hitches, but is more liable to jam. It differs from two half hitches in that the second half hitch is inside instead of outside the first one.

Axle hitch

The axle hitch is used to tie a hitch in a hard-to-reach place, or for extra security by having a double hold on an object. When the initial bight is passed around the object, the rest of the knot can be completed out away from the cramped location. The knot is finished with a bowline knot or other reliable knot that connects the working end to the standing part.

Halter hitch

The halter hitch is a type of knot used to connect a rope to an object. As the name implies, an animal's lead rope, attached to its halter, may be tied to a post or hitching rail with this knot. The benefit of the halter hitch is that it can be easily released by pulling on one end of the rope, even if it is under tension. Some sources show the knot being finished with the free end running through the slipped loop to prevent it from working loose or being untied by a clever animal, still allowing easy but not instant untying.

Two half-hitches type of knot

(The picture on this account is not correct; the are free smartphone apps available to learn how to properly tie two half hitches) The two half-hitches is a type of knot, specifically a binding knot or hitch knot. It consists of an overhand knot tied around a post, followed by a half-hitch. Equivalently, it consists of a half-turn around a post followed by a clove hitch of the running end around the standing part.

Bight (knot) curved section or slack part between the two ends of a rope

In knot tying, a bight is a curved section or slack part between the two ends of a rope, string, or yarn. A knot that can be tied using only the bight of a rope, without access to the ends, is described as in the bight. The term "bight" is also used in a more specific way when describing Turk's head knots, indicating how many repetitions of braiding are made in the circuit of a given knot.

Snuggle hitch

The snuggle hitch is a modification of the clove hitch, and is stronger and more secure. Owen K. Nuttall of the International Guild of Knot Tyers came up with this unique hitch, and it was first documented in the Guild's Knotting Matters magazine issue of January, 1987. Generally, hitches are used to attach a line to another rope or spar, pole, etc., and are usually temporary. Thus, they should be relatively easy to untie.

Harness bend

The harness knot is a general purpose bend knot used to join two ropes together. The knot can be tied under tension and will not capsize.

Swing hitch

Swing hitch is a way to tie a swing rope to a branch or other horizontal beam. Ashley describes it in ABOK as "... firm, strong, secure, and easily untied once the load has been removed."

History of knotting

Knots and knotting have been used and studied throughout history. For example, Chinese knotting is a decorative handicraft art that began as a form of Chinese folk art in the Tang and Song Dynasty in China, later popularized in the Ming. Knot theory is the recent mathematical study of unknots.
