Knot to tighten a rope

The tarp was smooth at six in the evening. By two in the morning, after the night dew, a belly of water sagged over the Unit's tent and the corner guy line lay on the ground. Very often the fault lies in the knot that was holding the tension. This guide shows which knot to tighten a rope fits each camp job: 15 knots, why each one works there, when to avoid it and how to test it. The step-by-step video is on each knot's page in the knots and lashings catalog.

🧭How does a knot to tighten a rope work?

Every taut rope has two ends doing different jobs. One is anchored to something solid, such as a tree, a stake or a pole. The other is the tension end, where you pull, adjust and lock off. A common mistake is to handle both with a plain overhand knot cinched down hard, which then neither tightens nor unties.

Tensioning knots work in one of two ways. Some create mechanical advantage: the rope runs through a loop tied in itself, like an improvised pulley, which is how the trucker's hitch works. Others rely on friction: turns around the standing part that slide when you push the knot and grip when the line pulls.

The material changes size too. According to the manufacturer Gossamer Gear, silicone-coated nylon stretches when wet, and dew or fog is enough for a shelter to sag by morning; with nylon guy lines, the effects add up. That is why a tensioning knot has to allow retightening.

⛺What is the best knot for tent guy lines?

Each guy line (the thin cord that runs from the tent fabric to the stake) has one end at the grommet and the other at the stake. At the tent end, the Figure 8 Knot forms a bulky stopper that will not pass through the grommet and keeps the cord from slipping out.

Adjustable hitches go on the stake end. The Midshipman's Hitch (ABOK #1855, in the Ashley Book of Knots), a variant of the taut-line hitch according to Wikipedia, slides along the rope when you push the knot and holds when the fabric pulls; the Animated Knots site warns that on slippery ropes, such as polypropylene and Dyneema, you should assume it will slip. The Adjustable Grip Hitch adjusts easily when slack and grips under load, but, according to the same site, it can come loose if tied close to a tree or a large object and slip under a hard jerk. The Adjustable Sling Knot, from the same family, appears in the catalog as a hitch that slides to adjust length and holds under load, leaving room to retighten.

To fasten the rope to a stake without threading the end, the Pile Hitch is tied in the bight and dropped over the top. It comes off very fast, but Animated Knots does not recommend it as a permanent tie. Tied in a series, it makes a rope fence between stakes.

🧺What is the best knot for a clothesline?

The clothesline belongs to the Trucker's Hitch: a loop in the middle of the rope becomes a pulley, the end goes around the tree, back through the loop and gets pulled. Animated Knots puts the theoretical advantage at 3 to 1, which drops to about 1.6 to 1 in practice because of rope-on-rope friction. That same friction holds the tension while you lock off the end with Two Half Hitches just below the loop.

At the anchor, the Bowline wraps the trunk with a fixed loop that does not choke and unties easily after being loaded. Its weak point, according to Animated Knots, is that it can shake loose when unloaded, as on an empty clothesline in the wind: check the knot before hanging the laundry. Two half hitches straight around the tree, always tied in the same direction, also anchor well.

One caution with the trucker's hitch: tied at the same spot on the rope every time, it can cause excessive wear, according to Wikipedia, so move the loop each time you rig it. Loads on vehicles fall under traffic law: see the guide to the knot for tying down a load.

🏕️What is the best knot for a tarp ridgeline?

A tarp or canvas sheet pitches smooth when it rests on a ridgeline, the rope between two trees that acts like the beam of a gabled roof. On the fixed side, the Round Turn and Two Half Hitches is the safe choice: the two wraps around the trunk hold the initial strain while you finish the half hitches with one hand, an advantage described by Animated Knots.

Anyone who pitches and strikes camp often prefers the Siberian Hitch: a figure eight around the standing part that releases with one pull and can be tied even with gloves on. According to Wikipedia, it was documented among the Nenets, a people of northern Russia, in a Swedish publication from 1991. Animated Knots rates it only moderately secure, great for the ridgeline and never for a critical load.

The tension side can also take the Farrimond Friction Hitch, a friction hitch that adjusts and releases with a tug on the end. Animated Knots credits the name to British actor Barry Farrimond, who reportedly demonstrated it in 2008 in Wales, and says it holds reasonably well on paracord; if it slips, an extra turn fixes it.

With the ridgeline set, the Prusik Knot comes in: two of them, tied with thinner cord, hold the ends of the tarp. It is named after Austrian mountaineer Karl Prusik and appears in an Austrian mountaineering manual from 1931. It grips when the loop is pulled and slides when you push the body of the knot, which lets you run the tarp to just the right spot.

🔓Which knots release fast when you break camp?

When you break camp, sometimes in the rain, nobody wants to fight a jammed knot. The Trucker's Hitch (Quick Release) gives the same tension and finishes with a slipped hitch that falls apart when you pull the end. According to Wikipedia, the slipped half hitch is the usual finish for the trucker's hitch when it needs to release easily; without the slip, it can jam under a heavy load.

The Highwayman's Hitch ties the rope to a bar or a branch and releases with a single pull. Its reputation as the getaway knot of mounted robbers has no evidence behind it, according to author Geoffrey Budworth, cited by Wikipedia. It can capsize and fall apart when the bar is much thicker than the rope: use it on a thin branch or a staff, never on a wide trunk.

The Clove Hitch starts almost every camp setup and comes off easily, but Animated Knots warns that, on its own, it slips and can also bind so tight that it will not untie. On a guy line that pulls sideways, finish it with half hitches. And coil up every loose end as soon as the knot opens: rope left on the ground becomes a trap.

🧪How do you test whether a knot will hold all night?

Test the tensioning knot at three moments: right after tying it, pulling hard close to the knot to see whether any turn creeps; with a short jerk in the middle of the rope, imitating a gust; and before bed, once the night dew has worked on the fabric. A hitch that creeps with every pull needs an extra turn or a different knot, and a tail that is too short can slip out when the rope gives.

The Companion class, starting at age 11, asks in item 3 of the Camping Craft section that the Pathfinder learn or review nine knots, including the trucker's hitch and the highwayman's hitch, according to the requirements of the South American Division (SAD) of the Seventh-day Adventist Church published on adventistas.org. The list for each stage is in the guide to knots by class, and the requirements with notes are on the Knots and Lashings honor page.

📋Table: which knot to use on each camp rope

The table brings together the guide's 15 knots, what each one does and the difficulty listed in the catalog. Take only the knots you can tie in the dark.

🛡️Where should you not tie, and how do you avoid accidents with taut lines?

A taut rope disappears in the dark, and a guy line or clothesline at neck or eye height knocks people down and hurts them. Keep lines out of walkways, such as the path to the restrooms, and mark each one with light-colored or reflective tape. Scout Life magazine, from Scouting in the United States, recommends reflective cord to prevent tripping at night.

Anchor only to live, thick trees. For hammocks, the Leave No Trace organization calls for a live trunk at least 6 inches (about 15 cm) across, attention to dead branches overhead and straps at least 1 inch (2.5 cm) wide, because thin material damages the bark. The rule was written for hammocks, which carry a person, and serves here only as a reference. A folded cloth between the trunk and a very tight rope is our own adaptation, in the spirit of minimum impact camping.

Never tie a rope to a power pole or an electric fence. Cemig, the power utility in the Brazilian state of Minas Gerais, advises that Carnival decorations should not be attached to poles and that no one should touch the wires, not even with objects. The rule is about decorations, but by analogy it applies to clotheslines and guy lines: a pole is not an anchor point. And no knot in this guide is meant to hold people: hammocks, swings, rappelling and zip lines call for certified gear and supervision by a trained adult; hammock rigging is covered in the guide to the knot to hang a hammock.
