Ropework
Ropework or marlinespike seamanship are umbrella terms for a skillset spanning the use, maintenance, and repair of rope. Ropework is used by seafarers, climbers and military personnel. Included are tying knots, splicing, making lashings, whippings, and proper use and storage of rope. While the skill of a sailor in the Age of Sail was often judged by how well he knew marlinespike seamanship, the knowledge it embraces involving docking a craft, towing, making repairs underway, and more is still critical for modern seafarers. Whippings A whipping knot is a means of holding the cut end of a rope together to prevent fraying and ensure ease of use. The simplest form is the common whipping. Constrictor knots can serve as temporary whippings while cutting ropes, as can a few layers of adhesive tape. Other fray-prevention techniques include back-splicing, aglets, or the application of a rubberized adhesive coating, resin, or paint to the cut end. Some modern synthetic fibers, ...

Lashing (ropework)
A lashing is an arrangement of rope, wire, or webbing with linking device used to secure and fasten two or more items together in a somewhat rigid manner. Lashings are most commonly applied to timber poles, and are commonly associated with cargo, containerisation, the Scouting movement, sailors, and gardeners. It has been imagined that the first lashing made by humans was wrapping a few strips of bark around a stone to hold it to a tree branch to make an ax to hunt and build with. In modern times, the same methods are used, but strips of bark and vines have been replaced with natural and synthetic fiber ropes. Scouts and campers use lashings to build camp gadgets and improve their campsites for comfort and convenience, including the building of rafts for transport and competitive events. Lashings are also used in pioneering, the art of creating structures such as bridges and towers, using ropes and wooden spars. There are still areas in the world where lashing spars (or poles ...

Common Whipping
The common whipping is the simplest type of whipping knot, a series of knots intended to stop a rope from unravelling. As it can slip off the rope easily, the common whipping should not be used for rope ends that will be handled. This whipping knot is also called 'wolf' whipping in some parts of the world. The ' Hangman's knot' is a variation of this whipping knot. The benefit of a common whipping is that no tools are necessary and the rope does not need to be unlaid. The problem is that it will slide off the end of the rope with little provocation. Other whippings avoid this by interleaving the whipping with the strands of the rope and creating friction with the strands to avoid slipping. Normally a natural fibre rope is whipped with twine. The size of the rope dictates the size of the twine. Any twine can be used, but tarred two strand hemp (marline) is preferred. Artificial-fibre ropes should have their ends fused by heat rather than whipped to prevent unravelling. Proc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knot
A knot is an intentional complication in Rope, cordage which may be practical or decorative, or both. Practical knots are classified by function, including List of hitch knots, hitches, List of bend knots, bends, List of loop knots, loop knots, and Rope splicing, 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 (knot), 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 Topology, 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 ...

Marlinespike
A marlinspike (, sometimes spelled marlin spike, marlinespike, or rchaicmarlingspike) is a tool used in marine ropework. Shaped in the form of a narrow metal cone tapered to a rounded or flattened point, it is used in tasks such as unlaying rope for splicing, untying knots, drawing 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. Historically a separate tool, the marlinspike is integrated in specialized versions of folding rigging and pocket knives. 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: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rope
A rope is a group of yarns, Plying, plies, fibres, or strands that are plying, twisted or braided together into a larger and stronger form. Ropes have high tensile strength and can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, String (structure), string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural fibre, natural or synthetic fibre, synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Splicing (rope)
Rope splicing in ropework is the forming of a semi-permanent joint between two ropes or two parts of the same rope by partly untwisting and then interweaving their strands. Splices can be used to form a stopper at the end of a line, to form a loop or an eye in a rope, or for joining two ropes together. Splices are preferred to knotted rope, since while a knot typically reduces the strength by 20–40%, a splice is capable of attaining a rope's full strength. However, splicing usually results in a thickening of the line and, if subsequently removed, leaves a distortion of the rope. Most types of splices are used on three-strand rope, but some can be done on 12-strand or greater single-braided rope, as well as most double braids. While a spliced three-strand rope's strands are interwoven to create the splice, a braided rope's splice is constructed by simply pulling the rope into its jacket. Types of splice *Back splice (or end splice) – A splice where the strands of the end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whipping Knot
A whipping knot or whipping is a binding of twine or whipcord around the end of a rope to prevent its natural tendency to fray. Some whippings are finished cleanly, as by drawing the bitter end of the cordage beneath the whipping itself. Others are tied off or have the end(s) of the twine sewn through the rope. According to ''The Ashley Book of Knots'', "The purpose of a ''whipping'' is to prevent the end of a rope from fraying ... A whipping should be, in width, about equal to the diameter of the rope on which it is put ... wo sailmaker's whippings a short distance apart, are put in the ends of every reef point, where the constant 'whipping' against the sail makes the wear excessive; this is said to be the source of the name ''whipping''."Ashley, Clifford W. (1944). ''The Ashley Book of Knots'', p.547. Doubleday. . The other type of stopping knot is a seizing knot. Whipping is suitable for synthetic and natural stranded and braided lines, including 3-strand rope, 4-strand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sailor
A sailor, seaman, mariner, or seafarer is a person who works aboard a watercraft as part of its crew, and may work in any one of a number of different fields that are related to the operation and maintenance of a ship. While the term ''sailor'' has its etymological roots from sailing, that is a time when sailing ships were the main mode of transport at sea, it now refers to the personnel of all watercraft regardless of the type of vessel, boat or ship. It encompasses people who operate ships professionally, be it for a military (navy) or civilian (merchant navy) or for Sailing (sport), sports or recreation. In a navy, there may be further distinctions: ''sailor'' may refer to any member of the navy even if they are based on land, while Seaman (rank), ''seaman'' may refer to a specific enlisted rank. Additionally, fisherman are seen as a distinct type of sailor, that is those engaged in fishing. Sailors have existed from the earliest periods in history as people as people used b ...

Age Of Sail
The Age of Sail is a period in European history that lasted at the latest from the mid-16th (or mid-15th) to the mid-19th centuries, in which the dominance of sailing ships in global trade and warfare culminated, particularly marked by the introduction of naval artillery, and ultimately reached its highest extent at the advent of steam power. Enabled by the advances of the related age of navigation, it is identified as a distinctive element of the early modern period and the Age of Discovery. Periodization Like most periodic eras, defining the age is inexact and serves only as a general description. The term is used differently for warships and merchant vessels. By the 14th century naval artillery was employed in Europe, documented at the Battle of Arnemuiden (1338). The 15th century saw the Iberian naval ventures all the way along the African Atlantic coast and across the Atlantic Ocean, starting the Age of Discovery. For warships, the age of sail runs roughly from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constrictor Knot
The constrictor knot is one of the most effective Binding (knot), binding knots.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 224-225.Brion Toss, ''The Complete Rigger's Apprentice'' (Camden, Maine: International Marine, 1998), 10-13.Geoffrey Budworth, ''The Complete Book of Knots'' (London: Octopus, 1997), 136-139. 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. History First called "constrictor knot" in Clifford Ashley's 1944 work ''The Ashley Book of Knots'', this knot likely dates back much further.Cyrus Lawrence Day, ''The Art of Knotting and Splicing, 4th ed.'' (Annapolis: Naval Institute Press, 1986), 112. Although Ashley seemed to imply that he had invented the constricto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adhesive Tape
Adhesive tape is one of many varieties of backing materials coated with an adhesive. Several types of adhesives can be used. Types Pressure-sensitive tape Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or solvent for activation and adheres to surfaces with light pressure. Typical adhesives are polymers such as acrylates, natural rubber, natural, and synthetic rubber. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term "adhesive tape" is used for these tapes. Water-activated tape Water-activated tape, gummed paper tape or gummed tape is starch- or sometimes animal glue-based adhesive on a paper backing which becomes sticky when moistened. A specific type of gummed tape is called reinforced gummed tape (RGT). The backing o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
