Knots and Lashings Honor

Recreational Activities

Requirements

  1. Define the following terms:
    • Bight (loop)
    • Running end (working end)
    • Standing part (fixed end)
    • Overhand knot
    • Eye loop (knotted loop)
    • Turn (loop)
    • Bend (fold)
    • Lashing
    • Joining of ropes
    • Whipping (working end)

    Answer: 1) Bight: the U-shaped fold made in the middle of the rope, without the parts crossing. 2) Running end: the free end of the rope, the one handled to make the knot. 3) Standing part (fixed end): the main/larger part of the rope, which remains stationary while you work with the end. 4) Overhand knot: the simple knot, the basis of many other knots. 5) Overhand loop (loop with a knot): the fixed loop formed when a knot is tied over the bight. 6) Turn (round turn): the loop made by wrapping the rope around an object or itself. 7) Curve (bend): the fold made in the rope when it changes direction. 8) Lashing: the knot (or set of turns and frapping turns) used to join/secure pieces, such as poles. 9) Bend (rope join): the knot that joins two ropes, splicing them to form a longer one. 10) Working end: the end of the rope that is actively handled when making the knot. — Knowing the terminology is the basis for learning any knot — written instructions use these terms; the working end is the active tip that performs the movement; the standing part is the rest of the rope. In scouting, these terms have been standardized internationally since 1907 (Baden-Powell) and are taught in every Pathfinder club.

  2. Know the precautions for the conservation of ropes.

    Answer: Rope care: store them dry (dampness rots them), coiled in wide loops (without knots), away from direct sunlight (UV degrades nylon), away from chemical products (fuels, acids), inspect them regularly for cuts/wear, take them out of use if damaged, wash them with water/neutral soap every 6 months. — UV sunlight is the worst enemy of synthetic ropes — they lose 50% of their strength in 2 years of direct exposure; nylon and polyester rot in a humid environment (mildew); chemical products weaken fibers invisibly. Inspect by flexing the rope — stiff or frayed spots indicate internal damage. Taking it out of use is a safety decision.

  3. Describe the differences between static and dynamic rope. List at least three uses for each one.

    Answer: Static: low stretch (1-5%), strong and stable — used in rappelling, hoisting loads, rescue, climbing (technical ascent). Dynamic: stretches 30-40%, absorbing the impact of a fall — used in sport climbing (to protect the climber in a fall), mountaineering, alpinism. Using the wrong one is dangerous and can break. — Dynamic rope is designed to withstand a 'fall factor' (FF up to 1.7-2): it stretches to absorb the peak force without injuring the climber; static rope breaks under a strong dynamic fall because it does not absorb impact. Typical diameters: static 9-11 mm for rappelling; dynamic 8.5-10.5 mm for climbing. Each type is UIAA-certified for specific use.

  4. Identify the following types of rope. Make a report describing the negative and positive points for the use of each one:
    • Polyester
    • Sisal
    • Nylon
    • Polypropylene

    Answer: 1) Polyester: POSITIVE POINTS — strong, low elasticity (does not stretch much under load), good resistance to UV rays and abrasion, maintains performance when wet; NEGATIVE POINTS — it is heavier and generally more expensive than polypropylene. 2) Sisal: POSITIVE POINTS — a natural fiber, cheap, with good knot grip and easy to handle; NEGATIVE POINTS — rough (can hurt the hands), rots with moisture, gets moldy, and loses strength when damp. 3) Nylon: POSITIVE POINTS — very strong and quite elastic, absorbing impacts and sudden loads; NEGATIVE POINTS — degrades with prolonged exposure to the sun and loses part of its strength when wet. 4) Polypropylene: POSITIVE POINTS — light and floats on water, does not absorb moisture, and is cheap; NEGATIVE POINTS — sensitive to heat (melts/weakens) and to sunlight, and is less resistant to abrasion. — Polyester is the most dimensionally stable synthetic, ideal for static load ropes. Sisal (Agave sisalana) is a natural fiber used in rustic settings; it loses up to 30% of its strength when wet and rots. Nylon (polyamide) has an elongation of 15-30%, great for cushioning falls, but weakens with prolonged UV radiation. Polypropylene is the only synthetic that floats on water (density <1), used in light nautical applications, but it melts from 165°C and degrades rapidly under the sun.

  5. What are some advantages and disadvantages of synthetic rope?

    Answer: Advantages: high strength, durability, they do not rot, they tolerate moisture, they are lighter, flexible, and offer a variety of elasticity. Disadvantages: they degrade under prolonged UV rays, melt with heat, can slip in some knots, cost more, and generate microplastics when they wear out. — Synthetic ropes (nylon, polyester, polypropylene, kevlar) have replaced natural fibers (sisal, hemp, cotton) in almost all technical applications due to their superior tensile strength (up to 5x more than sisal per mm²) and immunity to bacterial rot. However, photodegradation by UV rays can reduce strength by 50% in just 6 months of direct exposure. Heat above 150°C melts most of them. The smooth surface requires specific knots (figure-eight, prusik) because some traditional knots slip.

  6. According to the Bible, which type of static rope is the most resistant? Cite the Book, chapter, and verse.

    Answer: It is the rope formed by a threefold cord (three interwoven strands), according to Ecclesiastes 4:12: 'Though one may be overpowered, two can defend themselves; a cord of three strands is not quickly broken.' The text shows that the union of three strands is more resistant than two or one alone. — Ecclesiastes 4:9-12 deals with the strength of unity. Verse 12 uses the metaphor of the cord braided in three strands (in Hebrew, 'chut hameshulash') as a symbol of strength. Technically, traditional laid ropes use three strands twisted in the opposite direction to that of the threads, distributing the tension among them and preventing fraying — which gives greater strength than two-strand ropes. Spiritually, it is often interpreted as the union between husband, wife, and God.

  7. Do the following on a rope:
    • Short splice (Splice)
    • Eye splice (eye Splice)
    • Back splice (back Splice)
    • Finish the end of a rope with a double Manrope knot, a Diamond knot, or a Matthew Walker knot
    • Single Manrope knot
    • Pig knot (hog knot)

    Answer: Short splice: joins two ropes by interweaving their strands. Eye splice: forms a permanent loop at the end. Back splice: finishes the end, preventing fraying. Double rose knot / Matthew Walker: a decorative finishing knot. Single crown: a simple termination by unraveling and re-twisting. Stopper knot: a retention knot at the end of a rope. — Splices are joins made by interweaving the rope's own strands, without using knots, retaining up to 95% of the original strength. The short splice joins two ends; the eye splice forms a fixed load loop; the back splice seals the end. The Matthew Walker and the Double Rose knots are decorative ones typical of sailors, forming a rounded 'head' at the end. The Stopper knot, on the other hand, is just a volumetric increase to prevent the rope from passing through a pulley or hole.

  8. From materials found in nature, or with string, make two ropes at least 2 meters each:
    • A three-strand one
    • A triple-braided one

    Answer: For the three-strand one: separate it into three long strands, fasten the ends, and wind each one clockwise; then twist the three together counterclockwise until forming the 2m rope. For the triple braid: use three strands and alternately cross the outer one over the central one, forming a flat or cylindrical braid. — The three-strand laid rope is the classic ropemaker's method: each strand is twisted individually in the opposite direction to that of the final twist (laying), creating internal tension that keeps the strands interwoven under load. The triple braid crosses strands alternately — similar to hair braids — producing a more flexible structure, but one less resistant to tension than the laid rope. Useful natural materials: banana tree fibers, sisal, embira (bast), thin bamboo, coconut palm straw.

  9. Describe at least 3 plants that can provide material for making a rope.

    Answer: Sisal (Agave sisalana): a strong and durable fiber used in rustic ropes. Banana tree: fibers from the pseudostem, flexible and abundant. Embira / imbé: a vine of the Atlantic Forest, with resistant fibers in the inner bark. Others: hemp, jute, cotton, linen, bamboo, coconut palm straw, agave, nettle, and titica vine. — Plants with long fibers in the stem, leaves, or aerial roots are historical sources of cordage. Sisal (Agave sisalana) dominates world production. The banana tree provides fibers extracted from the beaten and shredded pseudostem. Embira (several species of Annona, Cecropia) is traditionally used by indigenous peoples in Brazil. Hemp (Cannabis sativa) and jute (Corchorus capsularis) were commercial standards. Cotton and linen give fine fibers, more used in string. Titica vine (Heteropsis flexuosa) is valued for its durability.

  10. Make from memory at least 20 of the knots below, telling the evaluator the name, what it is for, and its limitations. Make a report describing each one, citing what it is for and situations in which it should be used:
    • Anchor bend
    • Bowline
    • Double bowline
    • Square knot (reef knot)
    • Granny knot
    • Hangman's knot (noose)
    • Butterfly knot
    • Sheet bend (ordinary knot or adjustment knot or doubled hawser)
    • Constrictor (contraction knot or double clove hitch)
    • Double sheet bend (double ordinary knot)
    • Figure-eight knot
    • Fisherman's knot
    • Double fisherman's knot
    • Hunter's bend
    • Cat's paw
    • Thief knot (granny knot, or left-hand knot)
    • Clove hitch
    • Prusik knot
    • Running bowline (sliding bowline)
    • Fireman's chair knot (sailor's chair knot)
    • Chair knot
    • Sheet bend
    • Slip knot (running knot)
    • Reef knot
    • Surgeon's knot
    • Timber hitch
    • Overhand knot (single knot for joining)
    • Looped knot
    • Stopper hitch (round turn)
    • Monk's knot
    • Masthead knot (handcuff knot)
    • UIAA knot (Munter hitch)

    Answer: Each knot in the list fulfills a specific function. Classic examples: the Bowline makes a fixed rescue loop; the Double Bowline creates an improvised seat; the Square (reef) knot joins two equal ropes without tightening; the Hangman's/Gallows knot secures loads with a coil; the Butterfly gives a loop in the middle; the Constrictor tightens under tension; the Figure-eight is a retention and anchoring knot in climbing; the Fisherman's joins thin lines; the Prusik slides loose and locks under load; the Clove Hitch ties to masts; the Hunter's Bend joins bungee cords; the UIAA is a braking knot in rappelling.

  11. Correctly make the following lashings:
    • Square lashing
    • Diagonal lashing
    • Parallel or round lashing
    • Simple continuous lashing
    • Double continuous lashing

    Answer: Square lashing: joins two points crossed at a right angle (90°), very resistant to perpendicular forces. Diagonal lashing: joins crossed pieces at any angle, ideal when there is a tendency to spread apart. Parallel/round lashing: joins two parallel pieces or extends one. Continuous single lashing: ties several pieces in a row. Continuous double lashing: the same, with double ropes, more reinforced. — Lashings are techniques for joining poles using ropes, fundamental in Pathfinder pioneering. The square lashing is the basis of towers and tables, with alternating turns and fraps (tightening wraps). The diagonal lashing is used when the poles would tend to spread apart — the turns follow the diagonal between the pieces. The parallel/round lashing joins poles to lengthen them. The continuous single lashing joins multiple poles into a palisade (fences, rafts). The continuous double lashing increases strength using two parallel turns, ideal for heavy loads.

  12. Make a board with at least 25 knots.

    Answer: A backing board (wood, cork, or canvas) with 25 knots tied in real rope, fixed and identified by a label with the name of each one. It is recommended to include varied knots — retention (figure-eight, fisherman's), anchoring (bowline), friction (prusik), joining (square, sheet bend), lashings, and decorative — grouped by category, displayed for practical review. — The knot board is a practical display used by instructors. The backing is usually a smooth wooden board or coated MDF, on which each knot is glued/pinned with tacks and identified by a small plaque. Good practices: group by category (retention, anchoring, joining, friction, decorative); use distinct colored ropes per category; keep at least one characteristic knot from each family. It has become standard in museums and Pathfinder bases as a permanent pedagogical resource.
