Slipped Buntline Hitch
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 and 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. History Simple and effective, the buntline hitch dates to the age of sail, when it was used to secure buntlines to the foot of the sailsBrion Toss, ''Chapman's Nautical Guides: Knots'' (New York: Hearst Marine Books, 1990), 39.Clifford W.

Clove Hitch
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. 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. Usage This knot is particularly useful where the length of the running end needs to be adjustable, since feeding in rope from either direction will loosen the knot to be tightened at a new position. With certain types of cord, the clove hitch can slip when loaded. In modern climbing rope, the clove hitch will slip to a point, and then stop slipping. When tied around a carabiner, the load should pull on the end closest to its spine. With smaller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sails
A sail is a tensile structure—which is made from fabric or other membrane materials—that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or bonded filaments—usually in a three- or four-sided shape. A sail provides propulsive force via a combination of lift and drag, depending on its angle of attack—its angle with respect to the apparent wind. Apparent wind is the air velocity experienced on the moving craft and is the combined effect of the true wind velocity with the velocity of the sailing craft. Angle of attack is often constrained by the sailing craft's orientation to the wind or point of sail. On points of sail where it is possible to align the leading edge of the sail with the apparent wind, the sail may act as an airfoil, generating propulsive force as air pa ...

Round Turn
A turn is one round of rope on a pin or cleat, or one round of a coil. Turns can be made around various objects, through rings, or around the standing part of the rope itself or another rope. A turn also denotes a component of a knot. When the legs of a loop are brought together and crossed the rope has taken a turn. One distinguishes between single turn, round turn, and two round turns depending on the number of revolutions around an object. The benefit of round turns is best understood from the capstan equation. Riding turn A riding turn is a section of rope that passes on top of another section of rope, often parallel or at only a slight angle to the section below. Examples of riding turns can be seen in both the constrictor knot and the strangle knot. The second course of wrappings in some seizing knots can be referred to as riding turns. The formation of an unintentional riding turn on a sailing winch can cause it to jam. Single hitch A single hitch is a type of knot. ...

Two Half-hitches
Two half-hitches is a type of knot, specifically a binding knot or hitch knot. One variety consists of an overhand knot tied around a post, followed by a half-hitch. This knot is less often referred to as a clove hitch over itself, double half-hitch, or full-hitch. The following three-step process for tying the two half-hitches is also explained in the image gallery below. Click on the images for high-resolution versions. # Begin by forming a clockwise loop around the pole, with the working end of the rope on top. Bring the working end through the loop. At this point, you have an overhand knot around the pole. #Bring the working end down and to the left. Loop it under the standing end. Pull the working end through the loop just formed, tighten, and slide the knot along the standing end up to the post. #A correctly tied two half-hitches resembles a clove hitch tied around the standing end of the line, not a cow hitch.

Bight (knot)
In knot tying, a bight is a curved section or slack part between the two ends of a rope, string, or yarn.. "Any slack part of a rope between the two ends, particularly when curved or looped." 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. Bight vs. open loop Sources differ on whether an open loop or U-shaped curve in a rope qualifies as a bight. treats bights and loops as distinct, stating that a curve "no narrower than a semicircle" is a bight, while an open loop is a curve "narrower than a bight but with separated ends". However, ''The Illustrated Encyclopedia of Knots'' (2002) states: "Any section of line that is bent into a U-shape is a bight."

Necktie
A necktie, or simply a tie, is a piece of cloth worn for decorative purposes around the neck, resting under the shirt collar and knotted at the throat, and often draped down the chest. Variants include the ascot, bow, bolo, zipper tie, cravat, and knit. The modern necktie, ascot, and bow tie are descended from the cravat. Neckties are generally unsized but may be available in a longer size. In some cultures, men and boys wear neckties as part of office attire or formal wear. Women wear them less often. Neckties can also be part of a uniform. Neckties are traditionally worn with the top shirt button fastened, and the tie knot resting between the collar points. History Origins The necktie that spread from Europe traces back to Croatian mercenaries serving in France during the Thirty Years' War (1618–1648). These mercenaries from the Military Frontier, wearing their traditional small, knotted neckerchiefs, aroused the interest of the Parisians. Because of the differe ...

Four-in-hand Knot
The four-in-hand knot is a method of tying a necktie. It is also known as a simple knot or schoolboy knot, due to its simplicity and style. Some reports state that carriage drivers tied their reins with a four-in-hand knot, while others claim that the carriage drivers wore their scarves in the manner of a four-in-hand, but the most likely etymology is that members of the Four-in-Hand Club in London began to wear the neckwear, making it fashionable. The knot produced by this method is on the narrow side, notably asymmetric. For United States Army Uniforms of the United States Army, uniforms, and United States Navy Uniforms of the United States Navy, uniforms that include a necktie, the four-in-hand knot is one of three prescribed options for tying the necktie, the other two being the Half-Windsor knot, half-Windsor and Windsor knot, Windsor. Tying The four-in-hand knot is tied by placing the tie around the neck and crossing the broad end of the tie in front of the narrow end. The ...

Trucker's Hitch
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. Variations The portion of the trucker's hitch which differs in the following variations is the method used to form the loop which the working end slides through to produce the mechanical advantage. The different methods of forming the loop affect the ease and speed of tying and releasing and the stability of the final product. The variations are presented in order of increasing stability. Sheepshank style loop This version of the knot uses a sheepshank-like construction, in this kind of application also known as a ''bell ringer's knot'', to for ...

Marlinspike
A marlinspike (, sometimes spelled marlin spike, marlinespike, or rchaicmarlingspike) is a tool used in marine ropework. Shaped in the form of a polished metal cone tapered to a rounded or flattened point, it is used in such tasks as unlaying rope for splicing, untying knots, drawing marline tight using a marlinspike hitch, and as a toggle joining ropes under tension in a belaying pin splice. Marlinspikes are usually about long, but may reach or more when used for working heavy cables and ropes. They are usually made from iron or steel, whereas fids, similar in shape and function, are formed from wood or bone. The marlinspike may be a separate tool or one item on a pocket knife. Sailors who become proficient at knot tying, splicing, and sewing using the marlinspike are said to have mastered marlinespike seamanship, earning them the right to be known as ''marlin spikes'' or ''marlinspike seamen''. Uses Marlinspikes are used: * As levers to open strands of laid rope w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
