The open water season dictates its own rules, and for the owner of an inflatable vessel, the issue of reliable parking becomes a priority. PVC boat anchor cable It's not just a piece of rope bought in the nearest market, it's a critical safety feature that determines whether you're going to be swept away by the current or the wind into open water. Many beginners underestimate the load of wind gusts and use too light or short ropes, often resulting in the loss of an expensive anchor or even a boat flip.
Unlike metal boats, where the weight of the boat itself extinguishes some of the jerks, PVC It has a minimum mass and sailing, so the requirements for the anchor system are specific here. The optimal breaking load of the cable should be at least 250-300 kg, even if the anchor itself weighs only 3-4 kg. In this article, we will analyze all the nuances: from the choice of material to the methods of fastening, so that your fishing or rest will pass without unpleasant surprises.
Well-chosen anchor-rope Not only does it keep you fixed, it also keeps you comfortable on the water, and if you're planning to catch on the current or in windy weather, you can't save on this piece of equipment, so let's look at what materials are available and why a regular household rope can cause an accident.
Materials of manufacture: nylon, polypropylene or chain?
The choice of material is the first and most important step. There are many options on the market, but not all are suitable for inflatable boards, the main competitors are polypropylene and nylon (polyamide), each of which has its own unique properties.
Polypropylene It's the most popular option because of its low cost and buoyancy, and it doesn't sink in water, which is convenient if you accidentally drop the bay overboard, but it has a significant disadvantage: low elasticity. When you have the sudden jerks that characterize the wave, polypropylene is not cushioning well, transferring the load directly to the duck or the crum bolt. It also wears quickly against the rough bottom.
Nylon cord It's more expensive, but it's perfectly anchored, it's very tensile, and most importantly, it can stretch under a load of 15 to 20 percent, and it works like a shock absorber, and it dampens the boat's snatch. flyboat This is critically important because it reduces the risk of an anchor duck breaking away.
- 🌊 Floating: Polypropylene floats, nylon sinks (important when choosing color and visibility in water).
- 🛡️ Wear resistance: Nylon is more resistant to abrasion against stones and shells than polypropylene.
- 💧 Water absorption: Nylon absorbs water and becomes heavier, polypropylene remains light.
Use of metal chain as the main cable for boats from PVC The chain has a huge weight that can damage cylinders if handled carelessly, and lacks the necessary flexibility. The only acceptable use of the chain is a short fragment (1-1.5 meters) between the anchor and the main cable to improve the angle of attack, but this is more relevant for severe conditions.
Calculation of cable length and choice of diameter
The length of the rope is a parameter that is often determined by eye, which is a gross mistake. There is a golden rule of anchoring: the rope should be at least 3 lengths of depth in the parking lot, and in windy weather or on the current - up to 5-7 depths, this ratio is necessary for the cable to lie down and pull the anchor horizontally, allowing the paws to burrow into the ground.
If you drop anchor with a short cable, it will just hang vertically or, worse, pull out of the ground with every gust of wind. For a river with depths of 3-5 meters, the optimal length will be the length. anchor-fail It's about 20 to 25 meters, and at great depths (6 to 8 meters), the supply should be even more impressive.
The diameter of the cable is directly related to its bursting load: too thin cord will cut the hands when sampling the anchor, and too thick will take up a lot of space and have a large sailing capacity on the water. The optimal balance for boats 2.5-3.5 meters in length is in the range of 6-8 mm.
When buying, pay attention to the manufacturer's labeling, often on coils or tags. Not only is the thickness of polyamide cords indicated, but the load on the tear is guaranteed. Do not take the cable "back to the back", always leave a margin of safety at least 2-3 times the weight of a boat with a crew.
⚠️ Warning: Never tie the anchor cable directly to an inflatable duck without insurance! If a strong jerk is made, the duck can snatch along with a piece of balloon, resulting in a rapid loss of boat buoyancy.
Scheme of anchor cable attachment to the boat
Fixing is the weak link of any anchor system. There are several basic ways to fix, and the choice depends on the design of your boat and the availability of standard elements.
The most reliable option is the use of squirt-boltIf the trench is plywood, the bolt must go right through the plywood with a wide puck and nut. Inflatable elements use special pads-petaks that are glued or welded to the cylinder. It is important to use only stainless steel or brass, because ordinary metal rusts in one season.
The second option is to fix the squirrel This method is less reliable, because the load is not on the axis of the boat, but at an angle, which can lead to a turn of the boat side to the wave. If there is no other way out, use additional carbines and make sure that the rope does not rub against metal parts.
☑️ Checking of the attachment reliability
A third method, often used on small boats without transom plates, is to pass the cable through a carry handle or under an inflated camera, but this is only permissible as a temporary solution in a very weak current.
| Type of attachment | Reliability | Risk of damage to the boat | Recommendation |
|---|---|---|---|
| Rump bolt in the transmutant | High. | Minimum | Recommended |
| Ducks on a cylinder | Medium | High (at jerking) | Only with insurance. |
| For the sack. | Low. | Medium. | Not recommended |
| Around the leer stand | Medium | High (rub) | Permitted temporarily. |
Nodes and connections: how to reliably connect the cable and anchor
Even the most durable. nylon cord Knowing sea knots is a must-have skill for any boat owner, and anchoring to the cable is best suited to the Anchor knot (or Boulin modification), which does not slide and is easy to untie after loading.
If you connect the main cable to a chain or vertebral, use reliable carbines with a clutch or knit the "Double Eight" knot.
Always leave a small supply of cable (10-15 cm) after the knot, which will allow you to tie the connection if the main section is overused or weakened at the most inopportune moment.
Avoid using simple school nodes that turn into a monolith under load and require scissors to untie. On water, when hands are wet and cold, this becomes a serious problem.
Rules for safe anchoring and sampling
The anchoring process requires a well-established sequence of actions: first, the boat is led nose-to-head against the wind or current (whichever is stronger); only after a complete stop and the boat starts moving backwards (reverse) the anchor slowly descends; you can not anchor from the nose on the move - the cable can wind on the engine propeller or get entangled in the cylinders.
When you sample an anchor, you have to be smooth. Pull the boat behind the rope with your hands, picking it with your rings to the bottom, but not wrapping it on your arm! This is a gross mistake that can cause your hand to break off when you jerk abruptly. The cable has to be stacked in a separate container or on the clean floor of the boat.
- 🚫 Don't rewind. A rope on the arm or leg is 100% risk of injury.
- 🔄 Control it. position of the boat relative to the anchor in the sample.
- 🧼 Wash it. Fresh water after each fishing trip, especially in salt water.
If the anchor is dead (stuck between the rocks), don't pull the boat sharply. Try to approach the anchor from different sides, changing the tension vector. Sometimes it helps to create a slack: get as close as possible above the anchor, let the cable sag, knock on it (if there is a sonar or just a mooring) to knock the anchor off the spot.
⚠️ Attention: In strong wind (more than 10 m / s), anchoring on light PVC boat It can be dangerous. The boat can start to rock very hard, creating dangerous angles of roll, and in such conditions, it is better to go to shallow water or to the shore.
Care, storage and typical errors
The durability of your equipment depends on proper care. anchor-rope Even if it looks dry, there may be moisture inside the fibers, which, when frozen in winter, will destroy the structure of the material.
The best way to store the cable is to assemble it, wound on a special coil or in a bag protected from direct sunlight. Ultraviolet is the main enemy of polypropylene and nylon, it makes them brittle over time.
Typical mistakes of beginners:
- Use too light anchor, which does not hold on to the flow.
- The absence of a vertebra, which causes the rope to twist into a tourniquet.
- Fixing the cable to unreliable structural elements.
Regularly inspect the cable along the entire length, if you notice "shaggy", rubbed areas or a change in color, immediately replace the damaged area or the entire cable. There is no room for compromise with safety on the water.
Can I use a regular chord for the anchor?
Technically possible, but highly discouraged: household cords (often low-quality polypropylene) have low resistance to abrasion and UV radiation, and they can suddenly burst under a load that is specialized for the purpose of using a new system of electrical equipment. anchor-fail I'd be full-time.
What is the optimal weight for a 3-meter long boat?
For a PVC boat with a length of 3 meters with one or two passengers, the optimal weight of the anchor is 3-4 kg. If you fish on a strong current, the weight can be increased to 5 kg, but not more so as not to overload the bow.
Should we lubricate the cable?
Special lubrication for anchor cables is not required and even harmful, since sand and dirt will stick to the sticky surface, accelerating wear. Just wash it with clean water after use.
What to do if the cable is entangled in the engine screw?
Turn off the engine immediately! Don't try to spin the motor to "swipe" the cable, it's guaranteed to damage the glands or the screw itself. Carefully choose the cable with your hands, if necessary, cutting it if it jammed the screw.
How to calculate the length of the cable for a depth of 5 meters?
Use the formula: Depth × 4 (for calm water) or Depth × 6 (for wind/current). For 5 meters, this will be 20 meters in calm weather and up to 30 meters in adverse conditions.
