Finding a reliable anchor for an inflatable board is not just about buying an accessory, it's about safety and comfort on the water. Many beginners mistakenly believe that for an easy ride. flyboat Any cargo found in the garage will do, but the practice shows otherwise: an improperly selected cargo boat can damage cylinders, not keep the boat on the current or simply get lost in the depths, leaving you drifting.
In this article, we will analyze the physics of the anchoring process, compare different designs and determine which option will become the most important. The best solution for your model of watercraftYou will learn why the weight of an anchor depends not only on the displacement of the boat, but also on the type of bottom, and also get practical tips on organizing an anchor site.
Well-chosen equipment will allow you to feel confident even when the wind is stronger or on a strong current. Let's consider the key specifications that should be paid attention to first, to exclude situations where anchor It becomes a burden.
Selection criteria: weight, material and construction
The first thing that an PVC boat owner faces when choosing an anchor is a weight dilemma: An example that is too light will not be able to hold the vessel in gusts of wind, and an overly heavy one will create problems when lifting and transporting. There is a proven empirical formula that says that the weight of the anchor should be approximately 10% of the boat's carrying capacity or 1 kg per 1 meter of hull length.
However, blindly following the numbers can lead to errors if you do not consider the material of the product. Steel structures are high density, so with a smaller volume they provide the necessary weight. Aluminum analogs are lighter, but require more volume to achieve the same mass, which can be inconvenient for storage in a small volume. transporter-bag.
The design is also crucial. PVC boards are critically important to lack sharp edges and protruding parts that can pierce the balloon if handled carelessly. The ideal option should have a folding design or compact shape that allows it to be placed in the nose handle without damaging the rest of the equipment.
Overview of types of anchors for inflatable vessels
The market offers many modifications, but for flyboat There are several specific types that are most relevant, and each has its own advantages depending on the operating conditions and the type of bottom of the reservoir.
The most popular option is considered cat anchorIt's a classic that's proven to be very successful because of its foldable design, and four or five horns are very reliable for almost any ground, from silt to rocky bottom, and when folded, it takes up the minimum space, which is critical for small craft.
The second most popular type is fungus-anchorIt's ideal for slurry or sandy bottoms, where it works like a suction cup, but on hard clay soil or among rocks, its effectiveness drops dramatically, and its main advantage is absolute safety for cylinders, thanks to its round shape without sharp corners.
There are also plow and rack designs adapted for PVC. They provide excellent holding power, but often require longer phalin and careful handling. Some models are equipped with special soft paws or plastic linings.
- 🐙 Cat anchor: universal solution, folds, holds well on stones and grass.
- 🍄 Mushroom: Safe for cylinders, ideal for a sluggish bottom, but heavier at the same volume.
- ⚓ Plow (Denforth-light): High holding power on the sand, but may require protection of sharp edges.
- 🪨 Concrete cargo: It is a cheap option, but requires careful packaging to avoid damage to the boat.
⚠️ WARNING: When using homemade concrete or metal cargoes, be sure to wrap them in a soft cloth or place them in a tight bag. Any sharp ledge under tension can cause puncture. PVC material.
Calculation of weight and length of anchor rope
Many people ignore the importance of the length of the anchor rope (whalin) by focusing only on the weight of the load. This is a gross mistake. Even the heaviest anchor will not work effectively if the angle of thrust to the bottom is too large. For reliable fixation, the angle between the faline and the bottom should be minimal, so that the legs of the anchor crash into the ground, rather than pulling up.
The optimal length of the rope should exceed the depth of the reservoir in the parking lot by 3-5 times. If you anchor at a depth of 3 meters, the length of the rope should be at least 9-15 meters. The use of a short splint leads to the fact that the boat begins to prowl at the slightest wave, and the anchor constantly plucks from the bottom.
The following table can be used to calculate the weight, which takes into account the length of the vessel and the expected conditions:
| Boat length (m) | Min. anchor weight (kg) | Recommended weight (kg) | Type of bottom |
|---|---|---|---|
| 3.0 | 3.0 | 4.0 | Il, sand. |
| 3.0 - 3.6 | 4.0 | 5.0 - 6.0 | Grass, clay |
| 3.6 - 4.2 | 5.0 | 6.0 - 8.0 | Rocks, flow |
| more than 4.2 | 7.0 | 8.0 - 10.0 | Universal. |
In such circumstances retaining The usual cargo may not be enough, and the boat will begin to demolish.
Formula for calculating the length of the falin
For calm water, multiply depth by 3. For windy weather or currents, multiply depth by 5-7. Never tie anchor short "stretching" - this is a guarantee of breakdown.
Materials: Which is better – steel, aluminum or composite?
The choice of material directly affects durability and usability. Steel anchors are typically coated with zinc or enamel to protect against corrosion. It's a durable and inexpensive option, but it's prone to rusting at the chipping sites. Steel is heavier, which is good for holding power, but worse for carrying.
Aluminum alloys (e.g., duraluminum) do not rust and are much lighter than steel. However, to ensure the right weight, an aluminum anchor must be larger in size. This can be uncomfortable for compact boats. Also, aluminum is softer, and when hit by stones, the paws can deform.
Modern composite materials and stainless steel AISI 316 They're premium. They don't require painting, they don't fear salt water, they look aesthetic. But they can cost up to several times their normal value. For most amateur anglers, the optimal balance is painted steel or quality silumine.
If you often move between bodies of water with different depths, buy two anchors: light for shallow depths and heavy for great depths or currents. No one wants to carry extra pounds on fishing.
Organization of anchor and installation of rims
Just throwing an anchor into the water is not enough. You need to properly equip the boat. A critical element is having reliable rims (rings) to fasten the phalin. The regular rings on PVC boats are often only designed to fasten the boat to the transom or temporary mooring and may not withstand the thrust of the anchor in the wind.
For safe anchoring, it is recommended to install an additional anchor If the boat is designed to be, it is better to carry the falin through a rim gak or a special duck, so that the end can be quickly released if necessary, and the fastening should be done using wide petal linings so as not to damage the fabric of the board.
The falin itself must be made of a synthetic material that does not rot or absorb water (nylon, polypropylene). The use of chains between the anchor and the rope on inflatable boats is not recommended due to their weight and the risk of damage to the balloon when lifting.
☑️ Checking the anchor system
⚠️ Warning: Never tie the anchor end to a transom or elements that are not designed for heavy loads. In high winds, the boat can turn the side to the wave, which dramatically increases the risk. tippingThe anchor is always fixed to the nose!
Safety Techniques and Frequent Errors
One of the most dangerous mistakes is anchoring at the stern. This is strictly forbidden for outboard inflatable boats. If the boat turns lag to the wave, it becomes unstable and can easily flip over, especially if there are people on board. Always nose to the wave or the current.
Another problem is the bearded anchor, and if you're fishing in overgrown water, the anchor can get stuck in the snags or the grass, and in that case, having a snatch end (buerkna) will save the situation, and it's an extra thin cord tied to the top of the anchor, and if the main anchor is stuck, you pull at the breakaway end, change the angle of thrust, and release your paws.
Don't forget to check the condition of the anchor before each trip. Rust, weakened hinges at folding models or rubbed falin can fail at the most inopportune moment. Security The water depends on the little things.
The main rule of anchoring on a PVC boat: fastening only for the nose, the length of the phalin is 3-5 times greater than the depth, the absence of sharp edges on the cargo.
FAQ: Frequently asked questions
Can I use a cat anchor on a rocky bottom?
Yes, cat anchor is great for rocky bottoms, as its paws can catch bumps. However, there is a risk of getting stuck. In such cases, it is recommended to use a detachable end or choose a model with thin but strong legs that can be straightened by the force of the hands in the event of a hook.
What is the optimal diameter of the rope for an anchor?
For PVC boats up to 4 meters long, the diameter of a nylon or polypropylene cord is considered optimal 6-8 mm. The thinner will cut hands when sampling, and the thicker one will take up excess space and have sailing on the water.
Do I need to lubricate the hinges of the folding anchor?
Yes, moving parts must be periodically lubricated with silicone lubrication or WD-40 to prevent them from acidifying from salt water and dirt.
Why doesn't the anchor keep the boat flowing?
Most likely, the ratio of the length of the phalin to the depth (small length), the anchor is too light for current strength, or the type of bottom does not correspond to the design of the anchor (for example, a smooth bottom and an anchor without spikes).
