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] |
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. History Ship knowledge, ship stability and cargo operations Seamanship on a commercial level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
