Choosing an anchor for a 360 cm inflatable vessel is not just about buying a weighting, it is about safety and comfort on the water. Boats of this size have a certain sailing capacity and wind demolition, so an improperly selected mass or type of anchor can lead to the demolition of the vessel in shallow water or, conversely, to the loss of expensive equipment.
Many owners PVC 360 They make the classic mistake of relying on intuition or advice from vendors in fishing shops, where the range is often limited to cheap Chinese models, but to effectively park in the current or wind, you need to consider many factors, from the material of the bottom of the reservoir to the way the shipwreck is attached to the inflatable cylinder.
In this article, we will analyze the physics of the process, calculate the optimal weight and choose a design that is ideal for your use case, whether it is fishing on the river with the current or calm fishing on the reservoir.
Calculation of the optimal weight of the anchor for the boat 3.6 meters
The first and most important parameter is mass. There's a common misconception that the heavier the anchor, the better it holds. For inflatable boats, it's not quite that: Being overweight creates problems in lifting and transporting, and lack of mass will keep you from catching the ground.
The classic formula for calculating the weight of anchor (W) in kilograms is as follows: W = k * P, where P is the displacement of the vessel in tons, and k is the coefficient depending on the conditions (usually from 50 to 70). PVC 360 With the engine, fuel, equipment and crew, the total displacement rarely exceeds 600-700 kg (0.6-0.7 tons).
If you put the values in the formula, we get that for calm water is enough anchor weighing 3-4 kg. However, if you plan to fish on the current or in windy weather, the k factor increases, and the required weight can grow to 5-6 kg.
And you also have to consider wind demolition, and a boat that's 3.6 meters long, with a tent or a high visor mounted, acts like a sail. anchorage It must compensate not only for the inertia of the boat, but also for the constant pressure of the wind.
Types of anchors: what is better for an inflatable board
The market offers many designs, but not all of them are suitable for flyboatThe main problem with classic sea anchors is the risk of damaging cylinders when lifting or storing. Let's look at the most suitable options.
One of the most popular types is the anchor. Halla. It has good holding power on sand and gravel, but has protruding paws that can scratch PVC if handled carelessly. denforthIt has a flat design and two long legs, working perfectly on soft ground.
- ⚓ Danforth anchor: Ideal for sand and silt, compactly folds, but may not catch on a rocky bottom or overgrown grass.
- ⚓ Cat anchor: The versatile 4-legged version is good for rocky bottoms and thickets, but requires careful lifting so as not to tear the fabric.
- ⚓ Floating anchor (parachute): It doesn't go down, it keeps the boat on the water resistance, it's great for trolling or fishing in the plumb, it's absolutely safe for the sides.
PVC 360 boats also have stainless steel or collapsible galvanized steel anchors, which reduce the size of the boats during transportation, which is important for laying in a hazelnut.
Why not take cast-iron "pancakes"?
Cast-iron weights or "pancakes" work only on their own weight. On a hard clay bottom or overgrown grass, this structure simply slides over the surface without providing reliable fixation. In addition, the rough surface of cast iron can damage the protective layer of PVC when rubbed against the side.
Materials of manufacture and their impact on the operation
The choice of material is a trade-off between cost, weight and durability. 3.6 meters The weight of the equipment plays an important role, as often the equipment has to be carried to the water on foot.
Steel anchors (especially galvanized ones) are the gold standard. They're durable, heavy and relatively inexpensive. However, steel is prone to corrosion, and if you don't thoroughly dry and lubricate the anchor after every fishing trip, the rust can stain the boat floor and clothing.
Stainless steel is the perfect option, but it's expensive. It doesn't rust, it doesn't look aesthetically pleasing, it doesn't soil the boat. Aluminum anchors are very lightweight, which is good for carrying, but bad for holding power: to get the right weight, an aluminum anchor has to be very bulky.
| Materials | Weight (relative) | Corrosion | Price. |
|---|---|---|---|
| Galvanized steel | Heavy. | Medium (requires care) | Low. |
| Stainless steel | Heavy. | Missing. | High. |
| Steel is painted | Heavy. | Tall (soon rusting) | Low. |
| aluminum | Light. | Missing. | Medium |
When buying, pay attention to the quality of welds and painting. Cheap models often have sharp edges that must be treated with a file before using it. PVC.
Anchor rope and rope: critical elements
The anchor itself is only half the system, the other half is the anchor rope, and using a thin line or a rotten rope negates the benefits of even the most expensive anchor.
For a boat 3.6 meters long, the optimal length of the line should be 3-4 lengths of maximum depth at the parking lot. Usually 20-30 meters. The material should be floating or sinking? For classical anchors, it is better to use a sinking synthetic cord (polyamide, nylon) so that it does not get tangled under the feet and does not float.
⚠️ Attention: Never tie the anchor end directly to the transom or handle of a PVC boat! When a strong jerk (for example, if the anchor catches a snag and the boat carries the current) this can lead to a boat flipping or the handle being ripped out of the cloth. Use the anchor snag on the nose.
The diameter of the cord should be sufficient to be able to hold it confidently with your hands even in a wet state (usually 6-8 mm).
☑️ Checking the anchor system before exit
Techniques of installation and lifting of anchor
The correct anchor installation ensures that it will be buried in the ground, and not just lying on the surface, you need to approach the parking lot against the current or against the wind.
Put the anchor down, let it touch the ground, then slowly pull back, pulling the cord. When you give it the required length, pull the cord with a jerk to the legs of the anchor. denforth or Halla. They hit the ground, and then you can fix the phalo on the duck.
When you lift an anchor from a silted bottom, you often have a situation where the anchor is sucking. Don't pull vertically upwards, you risk turning the boat over. Get as close to the anchor as possible, pick a slack, then move to the side to change the angle of thrust, and jerk the anchor out of the silt.
For a rocky bottom where the anchor can get stuck between the stones, it is useful to use a webbing load or a special design with a ring on top of the anchor, allowing it to be pulled by the rod, freeing the paws.
Use a carbine with a vertebra between the anchor and the cord, which will prevent the rope from curling and will allow the anchor to quickly unfasten in an emergency if it is jammed in stones.
Safety and storage of equipment
After fishing, the anchor must be cleared of silt, sand and algae, and the dirt, when dried, turns into an abrasive, which will rub against the cylinders of the boat the next time it is used.
Keep the anchor separate from the inflated boat. When folded, the paws of the cat anchor or Danforth should be fixed or protected with a cover so that when shaking in the trunk of the car, they do not penetrate the PVC fabric.
⚠️ Warning: Do not store the wet anchor cord in a sealed bag or bag for a long time. Synthetics can "bloom" and the metal cable inside (if used in combination) will begin to quickly rust, weakening the structure.
Check the rim bolt on the bow of the boat regularly. PVC 360 If you notice that the fabric around the roach has begun to thin or deform, stop using immediately and go to repair.
The safety of the PVC boat depends not so much on the weight of the anchor as on the reliability of the mounting of the rim bolt and the correctness of the anchoring technique.
Can I use a 2 kg anchor for a 360 boat?
The 2 kg anchor is only possible under ideal conditions: no wind, no current, and no soft, viscous bottom (silt, clay) under any other conditions (wind, current, sand) such anchor will be ineffective and the boat will begin to demolish. For universal use, it is recommended to weigh from 3.5 to 5 kg.
Which anchor is best for trolling on a 3.6 meter boat?
The classic bottom anchors are not suitable for trolling, because they need to be raised and lowered all the time. The best solution is a floating anchor (parachute), which creates resistance to water, allowing you to hold the boat's nose against the wave or current, and easily folds into a small bag.
Do I need an anchor shaft with a chain for an inflatable boat?
The short piece of chain (0.5-1 meters) between the anchor and the main cord is useful. It presses the anchor paws to the bottom, improving the hook, and protects the synthetic cord from rubbing against sharp stones. However, for light boats PVC 360 is not strictly necessary if you use a quality nylon cord.
