Why do you need a swivel and when to use it?
A swivel is a small but extremely important device that is found in both fishing gear and automotive accessories. In fishing it prevents line twisting, which is especially important when fishing with spinning or feeder. In automotive applications, swivels are used in tow ropes, fastening straps and even in some load securing systems to prevent lines from twisting when loaded.
The main problem that beginners face is improper fastening of the swivel to the fishing line or cable. The knot must be reliable, but at the same time not weaken the strength of the base material. For example, the classic “figure eight knot” is suitable for monofilament, but can slip on braided line. And in automobile cables, an error in knitting can lead to rupture under load up to 50% of the declared strength.
In this article we will look at 5 proven methods tie a knot on a swivel, their pros and cons, as well as typical mistakes that even experienced fishermen and drivers make. Let us separately focus on choosing a swivel for a specific task - after all, not every swivel is suitable for sea fishing or towing a car weighing 2+ tons.
Types of swivels: which one to choose for your task
Before tying a knot, you need to understand which swivel is suitable for your situation. They differ in:
- 🔹 Material: brass (the most common, corrosion resistant), stainless steel (for sea fishing), plastic (lightweight, but cannot withstand heavy loads).
- 🔹 Size: No. 8–No. 14 for fishing (the thinner the line, the smaller the swivel), No. 16–No. 30 for cars (depending on the diameter of the cable).
- 🔹 Mounting type: with eyelet, with latch, with screw clamp (the latter is often used in tow straps).
- 🔹 Load: fishing ones can withstand 5–30 kg, automobile ones - from 1 to 10 tons.
For fishing for predators (pike, pike perch), it is better to take swivels from stainless steel with increased strength — they will not bend during a sharp bite. A brass swivel with screw clamp, but be sure to check it for breaking load (must be at least 2 times the weight of your car).
Top 5 swivel knots: step-by-step instructions
Now let's move on to practice. Below - 5 most reliable nodes, which are suitable for different types of fishing line and cables. Each of them was tested for strength and ease of tying.
1. Improved Clinched Knot
This is the most popular knot among anglers. It is suitable for monofilament and fluorocarbon, but not recommended for braid (may slip). Strength - up to 90% of the breaking load of the fishing line.
Thread the line through the eye of the swivel|Make 5-7 turns around the main line|Thread the end of the line through the loop at the eye|Moisten the knot and tighten|Trim the excess end (leave 2-3mm)-->
Pros: Knits quickly and is secure when tightened correctly.
Cons: May weaken on wet line, not suitable for thick cables.
2. Palomar Knot
A universal unit that is suitable for any types of fishing line, including braid. Strength - up to 95%. Often used in carp fishing and for attaching large swivels.
- Fold the line in half and thread the loop through the eye of the swivel.
- Tie a simple knot without tightening it.
- Thread the swivel through the loop and wet the knot.
- Tighten while holding both ends of the line.
Advice: If the line is thicker than 0.3 mm, make a double Palomar knot for extra security.
3. Uni Knot
This unit is suitable for braided fishing line and thin cables. Its strength reaches 85–90%, but it requires care when tightening.
Why is Uni better for braid?
Braided fishing line has a smooth surface, and classic knots (for example, “Clinch”) slip through it. "Uni" creates additional friction due to several turns, which prevents self-unraveling.
4. Bowline Knot for cables
A classic sea knot used in automotive cables and slings. It does not tighten under load and is easy to untie after use.
Important: to tow a car, the “Bowline” unit must be duplicated with a control unit, since it can weaken during jerking.
5. Rapala Knot
Specialized unit for swivels with eye and baits. It allows you to maintain the natural play of the bait, as it does not limit its movement.
Where to apply: ideal for fishing with wobblers and spinners, where freedom of movement of the bait is important.
For braided fishing line, always use knots with additional turns (Uni, Palomar), since the smooth surface of the braid reduces friction in the knot.
Typical mistakes when tying knots on a swivel
Even experienced fishermen and drivers sometimes make mistakes that lead to loss of fish or line breakage. Here are the most common:
- 🚫 Line end too short after the knot (less than 2 mm) - the knot can come undone.
- 🚫 Dry line when tightening — friction damages the fibers, reducing strength by 20–30%.
- 🚫 Using the wrong node (for example, “Clinch” for braid).
- 🚫 Twisting the line when knitting, this weakens it by 15–25%.
⚠️ Attention: If you are using a swivel with screw clamp (eg in a tow rope), never hand-tighten it. Use pliers to ensure even load distribution. Otherwise, the clamp may rotate under load.
Another common problem is swivel corrosion. Even stainless steel oxidizes over time, especially in seawater. Before each use, check the swivel for rust and mechanical damage. If he has lost more than 10% of its original weight due to corrosion, it needs to be replaced.
How to check the strength of a knot: test before use
It is not enough to just tie a knot - you need to test. Here's how to do it:
- Visual inspection: the knot must be smooth, without twists or creases in the fishing line.
- Slip test: Pull the main line and the end - the knot should not move.
- Load: For fishing gear, hang a weight equal to the weight of the intended catch (for example, 5 kg for pike). For an auto cable, load it to 50% of the maximum load (for example, if the cable is 3 tons, check at 1.5 tons).
| Line/rope type | Recommended node | Max. load (breaking load) | Test before use |
|---|---|---|---|
| Monoline (0.2–0.4 mm) | Clinch, Palomar | 85–95% | Suspend a load of 3–5 kg |
| Braided (0.1–0.3 mm) | Uni, Palomar (double) | 80–90% | A sharp jerk (imitation of a bite) |
| Steel cable (6–10 mm) | Bowline + control | 70–80% | Load 50% of max (e.g. 2 t for 4 t cable) |
| Synthetic cable (8–12 mm) | Figure Eight Knot | 75–85% | Tensile test (no jerking) |
⚠️ Attention: if you use a swivel in tow rope, after the load test, inspect the metal for microcracks. Even a small crack under load can lead to instantaneous rupture when towing.
Tips for caring for swivels and line
To make your swivel and line last longer, follow these recommendations:
- 🧼 After every fishing rinse the swivels in fresh water (especially after sea fishing).
- 🛢️ Lubricate metal swivels silicone grease Once a season - this prevents corrosion.
- 🔍 Please check before use ring mobility — if it sticks, replace the swivel.
- 🧵 Store fishing line with swivels in dark cool place — UV rays destroy nylon.
If the swivel begins to “squeak” when rotating, this is a sign of wear. Don't wait for it to jam - replace it right away, especially if you plan to catch trophy fish or tow a car.
For car cables the rules are even stricter:
- 🚗 After towing in rain or snow dry the cable, otherwise the metal will begin to rust from the inside.
- 🔧 Check once a year weld strength on a swivel (if it is welded).
- 📦 Store the cable in sealed caseto avoid dirt getting on the mechanisms.
Frequently asked questions about swivels and knots
Can I use the same swivel for mono and braid?
Technically yes, but the nodes will be different. For monofilament, “Clinch” or “Palomar” is suitable, and for braided line, “Uni” or double “Palomar” is better. Also note ear size — for braided it should be wider, since it is thicker than monofilament with the same breaking load.
Which swivel should I choose for towing a car weighing 2.5 tons?
The best option is a swivel made of brass or stainless steel with breaking load of at least 5 tons (double safety factor). It is better to choose a model with screw clamp and an additional safety ring. Examples of reliable brands: Trakker (for fishing and light ropes), Knot Right (for cars).
Why does a knot in a braided rope keep getting untied?
Braided line has smooth surface, so classic knots (for example, “Clinch”) do not hold well on it. Solutions:
- Use knots with additional turns (“Yuni”, “Palomar”).
- Wet the knot before tightening special gel for fishing line (increases friction).
- Check the swivel eye for wear - sharp edges can cut the line.
Is it possible to tie a swivel without knots using clamps?
Yes, for thick cables (from 8 mm) often used crimp sleeves or screw terminals. However, this method has disadvantages:
- Clamp can damage the cable fibers if installed incorrectly.
- Over time, the clamp becomes loose, especially when subjected to vibration (for example, when towing off-road).
- Not suitable for dynamic loads (jerks), as it does not absorb shock.
If you choose a clamp, be sure to use additional insurance (for example, wire bandage).
How many swivels can be used in one tackle?
Fishing gear usually has enough 1–2 swivels:
- One is between the main line and the leader (prevents twisting).
- The second is in front of the bait (if it is rotating, for example, a spinner).
More than two swivels worsen tackle sensitivity and can get confusing. Exception - bottom gear (for example, a feeder), where sometimes 3 swivels are installed to attach the feeder, leashes and sinkers.
