The Carrick bend is a knot used for joining two lines. The single carrick bend is a bend used in large rope In practice the free ends are seized onto their standing parts The diamond knot (or knife lanyard knot) is used as a decoration and joining knot in a cord with a loop such as a Whistle lanyard. The Ashley Book of Knots is an Encyclopedia of Knots first published in 1944 by Clifford Ashley. KNOT (1450 AM) is a commercial Classic Country music Radio station in Prescott Arizona, broadcasting to the Flagstaff - Prescott It is particularly appropriate for very heavy rope or cable that is too large and stiff to easily be formed into other common bends. [1][2] It will not jam even after carrying a significant load or being soaked with water. [3] The Carrick bend's aesthetically pleasing interwoven and symmetrical shape has also made it popular for decorative purposes.

Etymology
This knot's name dates back to at least 1783 when it was used by M. Lescallier in Vocabulaire des Termes de Marine. [1] Its origins prior to that are not known with certainty. There are several possible explanations for the name "Carrick" being associated with this bend. The Elizabethan era plasterwork of Ormonde Castle in Carrick-on-Suir shows numerous Carrick bends molded in relief. Romance and reality The Victorian era and the early twentieth century idealised the Elizabethan era Ormonde Castle (Caisleán Urmhumhan is a Castle on the River Suir on the east side of Carrick-on-Suir, County Tipperary, Ireland Carrick-on-Suir (Carraig na Siuire is a town in County Tipperary, Ireland. Or the name may come from Carrick Roads — a large natural anchorage by Falmouth in Cornwall, England. Carrick Roads is located on the southern Cornish coast in the UK, near Falmouth. A harbor or harbour (see spelling differences) or haven, is a place where ships may shelter from the Weather or are stored Falmouth (Aberfal is a town Civil parish and Port on the River Fal on the south coast of Cornwall, England, UK. Cornwall ( Kernow ˈkɛɹnɔʊ is the most southwesterly county of England, on the Peninsula that lies to the west of the River Tamar England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland The name may also have been derived from the Carrack, a medieval type of ship. A carrack or nau was a three- or four- masted Sailing ship developed in the Atlantic Ocean in the 15th century by the Portuguese [4]
Variations
The eight crossings within the Carrick bend allow for many similar looking knots to be made. The lines in a "full" or "true" Carrick bend alternate between over and under at every crossing. There are also two ways the ends can emerge from the knot: diagonally opposed or from the same side. The form with the ends emerging diagonally opposed is considered more secure. [1]
Unfortunately, with so many permutations, the Carrick bend is prone to being tied incorrectly. In several fields of Mathematics the term permutation is used with different but closely related meanings [3]
Appearance
Capsized
The Carrick bend is generally tied in a flat interwoven form shown above. Without additional measures it will collapse into a different shape, a process known as capsizing, when tightened. This capsized form is both secure and stable once tightened, although it is bulkier than the seized form below. When knot is allowed to capsize naturally under tension, considerable slippage of line through the knot can occur before tightening. The knot should be set carefully before loading. [5]
Seized
In the interest of making the Carrick bend easier to untie, especially when tied in extremely large rope, the ends may be seized to prevent the knot from collapsing when load is applied. This practice also keeps the knot's profile flatter and can ease its passage over capstans or winches. A capstan is a rotating machine used to apply Force to another element notably used on board ship and on dock walls for heaving-in or veering ropes cables and hawsers A winch is a mechanical device that is used to pull in (wind up or let out (wind out or otherwise adjust the " Tension " of a Rope or Wire rope [6]
The ends are traditionally seized to their standing part using a round seizing. For expediency, a series of double constrictor knots, drawn very tight, may also be used. The Constrictor knot is one of the most effective binding knots. [2] When seizing the Carrick bend, both ends must be secured to their standing parts or the bend will slip.
Decorative uses
In the decorative variation, both standing ends enter from one side and both working ends exit from the other. In this configuration the knot is known as the Josephine knot (macrame) or double coin knot (Chinese knotting). Macramé or macrame is a form of Textile -making using Knotting rather than Weaving or Knitting. Chinese knotting ( is a decorative handicraft arts that began as a form of Chinese folk art in the Tang and Song Dynasty (960-1279 AD in China This form of the Carrick bend is found depicted in heraldry, sometimes with the tails of heraldic serpents woven (or "nowed") into this knot. Heraldry in its most general sense encompasses all matters relating to the duties and responsibilities of officers of arms. In Heraldry and Vexillology, a charge is an image occupying the field on an escutcheon (or shield [7] In heraldry the knot is associated with Hereward the Wake and is known under the name "Wake knot". [4]
The knot can be tied using doubled lines for an even flatter, more elaborate appearance.
Security
The fully interwoven diagonal Carrick bend is the most secure variation. All other forms are inferior[3] and not recommended as bends. [1]
Although the Carrick bend has a reputation for strength, some tests have shown it to be as weak as 65% efficiency. KNOT (1450 AM) is a commercial Classic Country music Radio station in Prescott Arizona, broadcasting to the Flagstaff - Prescott [1]
