Bowline
The bowline ( or ) is an ancient and simple knot used to form a fixed loop 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. The common bowline shares some structural similarity with the sheet bend. Virtually all end-to-end joining knots (i.e., bends) have a corresponding loop knot. Although the bowline is generally considered a reliable knot, its main deficiencies are a tendency to work loose when not under load (or under cyclic loading), to slip when pulled sideways, and the bight portion of the knot to capsize in certain circumstances. To address these shortcomings, a number of more secure variations of the bowline have been developed for use in safety-critical applications, or b ...

Yosemite Bowline
A Yosemite bowline is a loop knot often perceived as having better security than a bowline. If the knot is not dressed correctly, it can potentially collapse into a noose,Youtube Video of failure with poorly dressed Yosemite bowlineYosemite Bowline not safe for climbing/ref> however testing reveals this alternative configuration to be strong and safe as a climbing tie-in. A Yosemite bowline is made from a bowline with the free end wrapped around one leg of the loop and tucked back through the knot, a final round turn and reeve commonly known as a "Yosemite finish." The knot's security is enhanced by preventing the bowline capsizing to form a highly dangerous slip knot. Additional safety is achieved by tying with a tail (see below). When finished, the working end forms a figure eight. Because of the danger of incorrectly dressing the Yosemite bowline and capsizing it even before it is set, it may be safer and less error-prone to use a standard or double bowline with a backup st ...

Cossack Knot
The Eskimo bowline, Cossack knot (russian: Казачий узел), reverse bowline, or 'anti- bowline' is in a class of knots known as 'eye knots' or 'loop knots'. The eye is formed in the end of the rope to permit attachments/connections. It is quite common in Russia and is often used instead of the bowline (ABoK #1010). In the simple bowline, the collar component forms around the 'standing part'. In contrast, the collar component of an Eskimo bowline forms around the outgoing eye-leg. On the first of arctic explorer John Ross' expeditions (1818) the Inuit (Eskimos) presented him a sled that contained several of these knots, showing that it is a genuine Inuit knot. The knot is not mentioned in ''The Ashley Book of Knots'' but in its Russian equivalent, the book "Морские узлы" (Marine Knots) by Lev Skryagin (1930–2000). The slipped version is known as Kalmyk loop. The Eskimo bowline is about as strong as and even more secure than the bowline, especia ...

Double Bowline
A double bowline (or round turn 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. Naming Though called "double bowline" by Clifford Ashley, this name is also reasonably descriptive of a different knot: the bowline on a bight The bowline on a bight is a knot which makes a pair of fixed-size loops in the middle of a rope. Its advantage is that it is reasonably easy to untie after being exposed to load. This knot can replace the figure-eight loop knot when tying into a .... Because of this ambiguity some sources differentiate by using one of the alternate names above. And at least one other source uses the name "double bowline" for a mid-line loop knot made by tying a basic bowline with a bight (knot), bight of rope instead of the end. Tying First, learn to tie the bowline by laying the working end on the standing part and twisting to form a loop (th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Bowline
The Portuguese bowline ( pt, Nó volta do calafate; also known as the French bowline and Lisbon surprise) is a variant of the bowline with two loops. The two loops are adjustable in size. Rope can be pulled from one loop into the other, even after tightening. The knot can be used as a makeshift Bosun's chair. Tying It is tied in a way that is similar to regular bowlines. File:Portuguese Bowline step 1.jpg, Make an overhand loop (loop with the working end on top). File:Portuguese Bowline step 2.jpg, Put the working end through the loop. File:Portuguese Bowline step 3.jpg, Put it through again. From here, the steps are the same as the regular bowline. File:Portuguese Bowline step 4.jpg, Put it around the standing end and back through the loop. See also *List of knots This list of knots includes many alternative names for common knots and lashings. Knot names have evolved over time, and there are many conflicting or confusing naming issues. The overhand knot, for example, is a ...

Bowline On A Bight
The bowline on a bight is a knot which makes a pair of fixed-size loops in the middle of a rope. Its advantage is that it is reasonably easy to untie after being exposed to load. This knot can replace the figure-eight loop knot when tying into a climbing harness. It is one of the two tie-in knots that are being taught by the German Alpine Club (DAV), generally being considered secure. Dangers 2011 testing shows that the knot might slip when only one loop is loaded. Cavers and canyoneers ought to fasten their cow-tail carabiner through both loops. Video with genuine ''et voilà!'' ending European cavers widely advocate the use of a figure eight twisted version of the bowline on a bight. Applications This knot can be used to provide a toe hold in the middle of a rope; to make an emergency bosun's chair; and to create an upper rope "block" to make a crude purchase by threading the rope round an anchor point and then back up through the loop. It is sometimes used in sport climbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knot
A knot is an intentional complication in cordage which may be practical or decorative, or both. Practical knots are classified by function, including hitches, bends, loop knots, and splices: a ''hitch'' fastens a rope to another object; a ''bend'' fastens two ends of a rope to each another; a ''loop knot'' is any knot creating a loop; and ''splice'' denotes any multi-strand knot, including bends and loops. A knot may also refer, in the strictest sense, to 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. History 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 (960–1279 AD) in China, later popularized ...

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. Etymology The name comes from the three loops that would be formed by tying this knot. Tying The knot is tied in the same way the original bowline is, except with a doubled rope (using a bight). An overhand loop is formed in the rope, the working end is passed back through that loop, behind the standing part of the rope, back through the loop and pulled tight. The working end (bight) forms a third loop, often larger than the two equal-sized loops. The size of the third loop depends on the length of the bight pulled through the loop. Bowline on the bight A bowline on the bight is a similar knot to the triple bowline. Instead of wrapping the bight around the standing end and then passing it back through the nipping loop, the two loops are passed through the bight so that it tightens on the standing end. It has only two active or available loops. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cowboy Bowline
The cowboy bowline or left-hand bowline, is a variation of the bowline loop knot. The cowboy bowline has the working end go around the standing part on the side closer to the loop and results with the working end outside the loop. In contrast, a regular bowline has the working end finishing inside the loop. (The "rabbit" goes around the "tree" in the opposite direction from normal.) ''The Ashley Book of Knots'' states that it is "distinctly inferior" to the standard bowlineClifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), p.188 #1034½. because of its similarity to the left-hand sheet bend.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 16. Various tests of the different versions' strengths show little difference; conjecture about either knot's vulnerability to some failure remain pretty much only that – conjectures. However, the left-hand bowline is much more stable under ring loading, as it then acts effectively as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Bowline
The Spanish bowlineThe complete guide to knots and knot tying — Geoffrey Budworth — p.190 — is a double loop knot that can be used to lift a person. For a conscious person, each loop is placed around a leg and the person holds onto the standing part of the rope. This knot can serve as a makeshift Bosun's chair. For an unconscious person one loop is placed around the arm pits and the second loop is placed around the knees. This knot has an elegant symmetry and can be tied quickly when mastered. Unlike the Portuguese bowline, each loop is separately fixed, which is a nice feature. It is a complicated knot however and if not properly tightened, it can slip. A fireman's chair knot is another double loop knot which is more practical, easier to tie and less prone to slipping although it lacks the elegance of a Spanish bowline.

Running Bowline
The running bowline is a knot consisting of a bowline looped around its own standing end to create a noose. The running bowline is strong and secure. It slides easily and can be undone just as simply. Tying Tie a bowline The bowline ( or ) is an ancient and simple knot used to form a fixed loop 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 ... in the end of a line with a small loop, and by appearance one then passes the standing part through the loop to form the noose. However, this method of forming the noose is practicable only for a short piece of line. Alternatively, one can tie the bowline tied directly around the standing part or, having tied the bowline first, one would form a bight in the standing part and pull it through the loop of the bowline.
