Rolling Hitch
The rolling hitch is a knot (see also Magnus hitch) used to attach a rope to a rod, pole, or another rope. A simple friction hitch, it is used for lengthwise pull along an object rather than at right angles. The rolling hitch is designed to resist lengthwise movement for only a single direction of pull.Clifford W. Ashley, ''The Ashley Book of Knots'' (New York: Doubleday, 1944), 292. A common usage while sailing is for rigging a Stopper knot#Nautical usage, stopper to relax the tension on a sheet (sailing), sheet so that a jammed winch or Block (sailing), block can be cleared. Naming At the turn of the 19th century the knot now known as the "rolling hitch" was called the "Magnus hitch" or "Magner's hitch", and the name "rolling hitch" referred to Round turn and two half-hitches, two round turns and two half-hitches. In 1841 Richard Henry Dana, Jr. used the present-day names in his work ''The Seaman's Friend'', and subsequent authors have continued to use this terminology.Ri ...

Taut-line Hitch
The taut-line hitch is an adjustable loop knot for use on lines under tension. It is useful when the length of a line will need to be periodically adjusted in order to maintain tension. It is made by tying a rolling hitch around the standing part after passing around an anchor object. Tension is maintained by sliding the hitch to adjust the size of the loop, thus changing the effective length of the standing part without retying the knot. It is typically used for securing tent lines in outdoor activities involving camping, by arborists when climbing trees, for tying down aircraft, for creating adjustable moorings in tidal areas, and to secure loads on vehicles. A versatile knot, the taut-line hitch was even used by astronauts during STS-82, the second Space Shuttle mission to repair the Hubble Space Telescope. Naming The adjustable loop forms of the rolling hitch and Magnus hitch, in addition to being called either of those two names, have also come to be known various ...

Richard Henry Dana, Jr
Richard Henry Dana Jr. (August 1, 1815 – January 6, 1882) was an American lawyer and politician from Massachusetts, a descendant of a colonial family, who gained renown as the author of the classic American memoir ''Two Years Before the Mast''. Both as a writer and as a lawyer, he was a champion of the downtrodden, from seamen to fugitive slaves and freedmen. Early life and education Dana was born in Cambridge, Massachusetts, on August 1, 1815 into a family that had settled in colonial America in 1640, counting Anne Bradstreet among its ancestors.Sullivan, 1972, p. 98. His father was the poet and critic Richard Henry Dana Sr. As a boy, Dana studied in Cambridgeport under a strict schoolmaster named Samuel Barrett, alongside fellow Cambridge native and future writer James Russell Lowell. Barrett was infamous as a disciplinarian who punished his students for any infraction by flogging. He also often pulled students by their ears and, on one such occasion, nearly pulled Dana's ear o ...

Adjustable Grip Hitch
The adjustable grip hitch is a simple and useful friction hitch which may easily be shifted up and down the rope while slack. It will hold fast when loaded, but slip when shock loaded until tension is relieved enough for it to again hold fast. It serves the same purpose as the taut-line hitch, e.g. tensioning a tent's guy line. This knot is also called the adjustable loop and Cawley adjustable hitch. It was conceived 1982 by Canadian climber Robert Chisnall. Tying The working end is wrapped inwards around the standing part (A-B) twice (1). Then another turn is made around both parts and a bight is pulled through the last wrap (2, 3) for the slipped version (left image), or just the end for the non-slipped version (right image). The knot needs to be pulled tight to actually grip (the slack is pulled out of the windings and the knot pulled tight at C and D). By pushing the knot along the standing part in direction of A, the line can be tightened. The grip can be improved by addin ...

Cow Hitch
The cow hitch, also called the lark's head, is a hitch knot used to attach a rope to an object. The cow hitch comprises a pair of half-hitches tied in opposing directions, as compared to the clove hitch in which the half-hitches are tied in the same direction. It has several variations and is known under a variety of names. It can be tied either with the end of the rope or with a bight. History A simple and useful knotted structure, the cow hitch has been known since at least the first century when described by Greek physician Heraklas in a monograph on surgical knots and slings. Known under a variety of names, this knot has been used both on land and at sea. The common alternate name "lark's head" is attributed to Tom Bowling (pseudonym) in the 1866 work ''The Book of Knots'' which is presumed to have been adapted from a French manuscript; lark's head is a literal translation of the French name for the knot, ''tête d'alouette''.Ahsley, p. 11. Variations The underlying ...

Half Hitch
The half hitch is a simple overhand knot, where the working end of a line is brought over and under the standing part. Insecure on its own, it is a valuable component of a wide variety of useful and reliable hitches, bends, and knots. Two successive half hitches tied around an object makes up the common clove hitch. Two successive half hitches tied around the standing part of a rope is known as two half-hitches or double half hitch. One instance where a half hitch stands on its own without additional embellishment is when added to a timber hitch to help stabilize a load in the direction of pull. A timber hitch is tied on the far end of the load to bind it securely and a half hitch made at the forward end to serve as a guide for the rope. In this instance, the half hitch combined with a timber hitch is known as a killick hitch or kelleg hitch. The knot is attractive to the eye and so is used decoratively for French whipping which is also known as ''half hitch whipping''. S ...

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. ...

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 ...

The Ashley Book Of Knots
''The Ashley Book of Knots'' is an encyclopedia of knots written and illustrated by the American sailor and artist Clifford W. Ashley. First published in 1944, it was the culmination of over 11 years of work. The book contains 3,857 numbered entries (the final number, "3854", is added to by three "1/2" #s (794.5, 1034.5, & 2585.5) and, in later editions of the book, #1425a for Hunter's Bend; and one number has no entry) and approximately 7,000 illustrations. The entries include knot instructions, uses, and some histories, categorized by type or function. It remains one of the most important and comprehensive books on knots. Use as a reference Due to its scope and wide availability, ''The Ashley Book of Knots'' has become a significant reference work in the field of knotting. The numbers Ashley assigned to each knot can be used to unambiguously identify them. This helps to identify knots despite local colloquialisms or identification changes. Citations to Ashley numbers are usua ...
