Stopper Knot
A stopper knot (or simply stopper) is a knot that creates a fixed thicker point on an otherwise-uniform thickness rope for the purpose of preventing the rope, at that point, from slipping through a narrow passage, such as a hole in a block. To pass a rope through a block, or hole, is to reeve it. To pull it out is to unreeve it. Stopper knots prevent the rope from unreeving on its own. They are also used to lower the chances of rappelling off the end of a rope. "Stopper" has three distinct meanings in the context of knotting and cordage. A decorative stopper knot may be referred to as a lanyard knot. A monkey's tail "is a permanent or semipermanent stopper that is put in the bight as well as the end. It is also called single throat seizing, seized round turn, clinch, and pigtail...A small round turn is first taken, and a throat seizing, in length about a quarter of the round of the clinch, is put in. The monkey's tail is preferred for the purpose just described because it doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Figure-eight Loop
Figure-eight loop (also figure-eight on a bight, figure-eight follow-through, figure-eight retrace, Flemish loop, or Flemish eight) is a type of knot created by a loop on the bight. It is used in climbing and caving. The double figure eight is used to put a loop in the end of a rope, or around an object. It is relatively easy to tie and is secure, but can become difficult to untie after heavy loading, and can jam badly in any rope type. Tying methods On a bight A figure-eight loop is created by doubling the rope into a bight, then tying the standard figure-eight knot. In climbing, this knot is used to save time when repeatedly attaching the rope to climbing harnesses, using locking carabiners, such as when a group of people are climbing on the same top-rope. Follow-through Alternatively, to tie the knot directly around an object, the follow-through method must be used. * Tie a regular figure eight knot with a significant amount of extra tail. * Loop the tail around the ...

Belay
In climbing and mountaineering, belaying comprises techniques used to create friction within a climbing protection system, particularly on a climbing rope, so that a falling climber does not fall very far. A climbing partner typically applies tension at the other end of the rope whenever the climber is not moving, and removes the tension from the rope whenever the climber needs more rope to continue climbing. The belay is the place where the belayer is anchored, which is typically on the ground, or on ledge (where it is also called a belay station) but may also be a hanging belay where the belayer themself is suspended from an anchor in the rock on a multi-pitch climb. Description Belaying is a critical part of climbing safety. Correct belaying methods allow a belayer to hold the entire weight of the climber with relatively little force and easily arrest falls. In its simplest form, a belay consists of a rope that runs from a climber to another person (the belayer) who c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nautical
Seamanship is the art, competence, and knowledge of operating a ship, boat or other craft on water. The'' Oxford Dictionary'' states that seamanship is "The skill, techniques, or practice of handling a ship or boat at sea." It involves topics and development of specialised skills, including navigation and international maritime law and regulatory knowledge; weather, meteorology and forecasting; watchkeeping; ship-handling and small boat handling; operation of deck equipment, anchors and cables; ropework and line handling; communications; sailing; engines; execution of evolutions such as towing; cargo handling equipment, dangerous cargoes and cargo storage; dealing with emergencies; survival at sea and search and rescue; and fire fighting. The degree of knowledge needed within these areas is dependent upon the nature of the work and the type of vessel employed by a seafarer.

Double Fisherman's Knot
The double fisherman's knot or grapevine knot is a bend. This knot and the triple fisherman's knot are the variations used most often in climbing, arboriculture, and search and rescue. The knot is formed by tying a double overhand knot, in its strangle knot form, with each end around the opposite line's standing part. Usage A primary use of this knot is to form high strength (round) slings of cord for connecting pieces of a climber's protection system. Other uses This knot, along with the basic fisherman's knot can be used to join the ends of a necklace cord. The two strangle knots are left separated, and in this way the length of the necklace can be adjusted without breaking or untying the strand.

Strangle Knot
The strangle knot is a simple binding knot. Similar to the constrictor knot, it also features an overhand knot under a riding turn. A visible difference is that the ends emerge at the outside edges, rather than between the turns as for a constrictor. This knot is a rearranged double overhand knot and makes up each half of the double fisherman's knot.

Rope Rescue
Rope rescue is a subset of technical rescue that involves the use of rope, be it steel or cable rope, or more commonly used nylon, polyester, or other type of rope. Principles The key to any type of rescue is understanding and identifying the principles which are involved. Once the principles are identified, appropriate techniques or methods, which fits the circumstances, can be determined and applied. More recently, noncommittal vertical rescue techniques have been introduced. These skills make it possible to rescue a subject from a vertical environment without exposing the rescue professional (volunteer or paid) to the danger or risk of the vertical environment. These techniques involve skills used to rescue an individual(s) from their precarious situation, without sending a rescue professional over the edge or suspending them from the rope and safety equipment. An example of one such technique is the ''clip, snip, and lower/raise'' technique. It is often used for fall recov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing
Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders) to small boulders. Climbing is done for locomotion, sporting recreation, for competition, and is also done in trades that rely on ascension, such as construction and military operations. Climbing is done indoors and outdoors, on natural surfaces (e.g. rock climbing and ice climbing), and on artificial surfaces (e.g. climbing walls and climbing gyms). The sport of climbing evolved by climbers making first ascents of new types of climbing routes, using new climbing techniques, at ever-increasing grades of difficulty, with ever-improving pieces of climbing equipment. Guides and guidebooks were an important element in developing the popularity of the sport in the natural environment. Early pioneers included Walter Bonatti, Riccardo Cassin, Hermann Buhl, and Gaston Rébuffat, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decorative Knot
A decorative or ornamental knot (also fancy knot) is an often complex knot exhibiting repeating patterns. A decorative knot is generally a knot that not only has practical use but is also known for its aesthetic or ornamental qualities.Owen (1994), p.125. Access date: 2010-02-18. "They can be used for practical purposes or pure decoration. Often originating from maritime use, "decorative knots are not only serviceable and functional but also enhance the ship-shape appearance of any vessel." Decorative knots may be used alone or in combination, and may consist of single or multiple strands.Penn, Randy (2004).

Ashley's Stopper Knot
Ashley's stopper knot, also known as the oysterman's stopper, is a knot developed by Clifford W. Ashley around 1910. It makes a well-balanced trefoil-faced stopper at the end of the rope, giving greater resistance to pulling through an opening than other common stoppers. Essentially, the knot is a common overhand noose, but with the end of the rope passing through the noose eye, which closes upon it. It may be multiplied to form a larger knot with more than three bights appearing around the knot. It is the result of implementing a double wall knot in one strand. Ashley developed this knot in trying to duplicate a knot he saw on a boat in a local oyster fishing fleet. When he had a chance to observe the knot up close at a later time he realized it was just a badly water-swollen figure eight stopper knot. Tying # Form an overhand noose, or simply tie an overhand knot around the standing part as shown. # Tighten the overhand portion of the knot around the standing pa ...

Stevedore Knot
The stevedore knot is a stopper knot, often tied near the end of a rope. It is more bulky and less prone to jamming than the closely related figure-eight knot. Naming In ''The Art of Knotting & Splicing'', Cyrus Day explains that "the name originated in a pamphlet issued about 1890 by the C.W. Hunt Company, which sold rope under the name 'Stevedore'. It was subsequently adopted by dictionaries, engineers' handbooks, and other works of reference, and it is now firmly established in books, if not in the vocabulary of seamen."Cyrus Lawrence Day, ''The Art of Knotting and Splicing, 4th ed.'' (Annapolis: Naval Institute Press, 1986), 40. Despite this history, many sources, including The Ashley Book of Knots, presume that the knot was used by stevedores in their work loading and unloading ships. The apparent aspect of the knot favored by transmission-line workers (to which the Hunt pamphlet was targeted) is the knot's remaining easily untied after heavy loading. It should also b ...
