Choosing the right anchor for an inflatable boat is not just a matter of convenience, but a critical safety feature on the water. Many beginners make the mistake of buying the first cargo they get or using unsuitable weight structures that can cause the boat to be blown down by wind or current into a danger zone. Safe parking It depends on many factors, including the type of bottom, wind strength and specifications of the boat itself.
Unlike metal boats, where the weight of the anchor can be tens of kilograms, for example, the weight of the boat is very high. PVC-boat There are strict weight limits to avoid damaging the sides and bottom when lifting. The wrong device can simply slide over the silt or sand without providing a fixation, or, conversely, get stuck dead, creating an emergency situation. In this article, we will discuss in detail what type of attachment will suit your vessel.
The modern market offers a wide range of models, from classic cats to modern folding structures with plastic paws. Understanding the physics of the process and the technical specifications of various types of anchors will allow you to make informed choices that will ensure a relaxing fishing or rest.
Key criteria for choosing an anchor device
The first and most important parameter is the weight of the anchor. There is a rule of thumb that the mass of the anchor should be approximately 10% of the displacement of the boat, but for inflatable boats this figure is often adjusted in a lower direction to avoid damage. Optimal weight It usually ranges from 1.5 to 4 kg, which is enough to hold a boat up to 4 meters long in moderate weather.
The second critical factor is the design of the paws and their ability to submerge. The bottoms of the bodies of water can be vastly different, from viscous silt and soft sand to stony beds and thickets of grass. There is no universal solution, but some models show better results. hookability on heterogeneous surfaces.
⚠️ Warning: Using an overly heavy anchor on an inflatable boat can cause cylinders to break down when lifting, especially in windy weather when the boat starts to roll from side to side.
Also, the material of manufacture must be considered: Steel anchors are strong but corrosive if they are not coated properly; aluminum alloys are lighter but less durable when hit by rocks; plastic elements reduce the risk of damage to the side, but may be less durable under extreme loads.
Overview of the main types of anchors for PVC boats
The most popular option among inflatable boat owners is the cat anchor, a classic design consisting of a central spindle and four sliding legs. Cat anchor It's convenient because it takes up a minimum of space when folded, and its legs can be stretched or squeezed as needed, but it has a significant drawback: it doesn't hold well on a solid clay bottom and can get stuck between rocks.
Another common type is the plow or the Admiralty anchor in miniature, which is very penetrating and can be held securely on sand and silt. Plow anchors. They often have fixed legs, which makes them more cumbersome when stored, but more efficient when operated, and they're less prone to rope overlap, which happens to cats.
- 🦀 Cat anchor: It is ideal for storage in a bag, versatile, but can slide on a smooth bottom.
- ⚓ Danforth anchor (mini): excellent engagement on sand and silt, compact, but afraid of rocky bottom.
- 🪨 Gravitational anchors: just loads, effective only on a very viscous bottom or in the absence of current.
- 🌿 Broad paw anchors: They are designed specifically for snatching grass and snags.
And one of the things that we're talking about today is the folding anchors, which have a rotating mechanism, and they combine the compactness of a cat with the efficiency of a plow, and when you pull the faline, the paw turns, allowing you to pull the anchor out if it's stuck in the ground. innovation It greatly simplifies the process of lifting the anchor from deep places.
Calculation of weight and length of anchor rope
Many anglers mistakenly believe that the heavier the anchor, the better. In practice, for a PVC boat with a length of 3 meters, it is enough to weigh 1.5-2 kg, and for a 4-meter boat - 2.5-3 kg. Exceeding this weight will not give a proportionate increase in reliability, but will create unnecessary problems during operation. retainer design.
The length of the anchor rope (falina) should be 3-5 times the depth of the reservoir where you plan to park, this is necessary so that the thrust falls on the anchor horizontally, pressing its legs to the bottom, rather than pulling them vertically up. demolition Even if you have a heavy anchor.
| Boat length (m) | Recommended weight (kg) | Cord diameter (mm) | Min. length of falin (m) |
|---|---|---|---|
| 2.0 – 2.8 | 1.0 – 1.5 | 3.0 – 4.0 | 15 |
| 2.9 – 3.6 | 1.5 – 2.5 | 4.0 – 5.0 | 20 |
| 3.7 – 4.5 | 2.5 – 3.5 | 5.0 – 6.0 | 25 |
| 4.6. and more | 3.5 – 5.0 | 6.0 – 8.0 | 30+ |
The material of the faline also matters: Synthetic cords (nylon, polypropylene) are strong, rotten and easily washed off dirt. The chain is used rarely and only as a short stretch (1-2 meters) between the anchor and the cord to provide horizontal force on the paws. The optimal choice for most PVC boats is a wicker synthetic cord with a diameter of 4-6 mm.
Anchoring technique and safety
The correct anchoring technique ensures that the boat does not go round and confuse the gear, approach the parking place against the current or against the wind, slowly ejecting the falinha. When the boat is at the right point, the anchor is smoothly lowered to the bottom, after which the boat is allowed to go a little forward so that the anchor lay down correctly, and only then select the slack and fix it. duck-falina.
☑️ Safe parking rules
Never tie the falin to yourself or to a part of the body! In the case of a sudden jerk of the boat, this can lead to serious injuries or even drowning. flat-bolt Or special attachments on the transom or the bow of the boat, and if the boat is anchored in a violent storm, there is a risk of water filling the cockpit across the board.
⚠️ Warning: With strong winds or currents, the angle of roll of the boat can increase, and water will start to overflow over the side, in such conditions, prolonged parking at one anchor is dangerous.
To improve safety in difficult conditions, it is recommended to use a two-armor scheme (in stretch) or combine the anchor with an etched motor, which allows you to stabilize the boat and eliminate rotation around the axle, which is especially important for overnight stays or strong waves.
The problem of stuckness and solutions
The worst thing is that the anchor gets stuck in a snag, a rock, or a bottom thicket, and trying to pull it out by force can damage the boat or lose the anchor along with the phalin, and in these cases, the "kick-off" method helps. ring-top anchors (if the design permits) or a special uncoupling system is used.
If the cat anchor is stuck with its paws, try slowly pulling the boat right above the anchor, swinging it from side to side, and then pulling it in the opposite direction. Often this allows you to release your paws. For a rocky bottom, it is better to use an anchor with a single horn or a special structure that, when stuck, simply flips over.
What if the anchor is stuck dead?
If standard methods don't work, you can use buoys. You can tie an empty plastic canister or buoy to the falina, which will allow you to return to the place of loss later, cut the falin at the anchor itself (if you have a harpoon knife), or try to pull it out with a more powerful boat, changing the thrust vector.
It's important to always carry a sharp knife with you, fixed in an accessible place. In an emergency, when the anchor rope is wound on the engine screw or entangled in a way that threatens safety, the only solution is to cut the rope. anchor-lineWe can try to get the anchor later.
Care, storage and preparation for the season
The anchor, like any other equipment, requires maintenance. After each foray, especially into salt water or muddy water bodies, it must be thoroughly washed with fresh water. Metal parts should be dry-wiped and, if necessary, lubricated with anti-corrosion compounds to prevent rust that can stain the boat and clothes.
It is better to store the anchor in a separate bag or case, so that the sharp edges of the paws do not damage other things in the trunk or the boat itself.loop" at the most inopportune time.
- 🧼 Wash the anchor with fresh water after each use in salt water.
- 🔧 Regularly check the place of connection of the spindle and paws for cracks.
- 🧵 Check the slack for signs and signs.
- 📦 Keep your equipment in a dry, ventilated room.
Use bright tape or shrinkage on the spindle of the anchor-cat, which not only protects the metal, but also makes the anchor more visible at the bottom if you have to look for it, and also helps you quickly navigate which side it lies on.
Regularly checking equipment before the season will avoid unpleasant surprises on the water. Make sure that all moving parts are free and the rope has not lost its strength under the influence of ultraviolet light and time.
Final selection recommendations
Choosing the best anchor for your PVC boat is to find a balance between weight, dimensions and the type of bottom you most often plan to fish or relax on. folding-cat anchor Weighing about 2-3 kg with a reliable synthetic phalin of sufficient length.
The golden rule is that the weight of the anchor should be sufficient to hold, but not excessive to avoid damaging the boat; the length of the faline should exceed a depth of 3-5 times for horizontal effort.
Don't skimp on materials. Cheap metal can burst when loaded, and a thin cord can rub against seashells. Investing in a quality anchor is an investment in your safety and comfort on the water. Remember, in an emergency, it's this little piece of metal that can save your boat from being carried away into open water or into dangerous rocks.
Can I use a heavy stone or sandbag instead of an anchor?
The only way to use a stone or a sandbag is to drag it along the bottom, and only on a very viscous sludge, and the main disadvantage of this anchor is that it has no legs to bury in the ground, and on sand, clay or currents, it will simply drag it along the bottom without providing a safe parking lot, and a sharp stone can damage the bottom of the boat when lifting.
Which color of falin is better to choose?
The best way to choose a falin is to choose a bright, contrasting color (orange, yellow, bright red) that will allow you to always see its position in the water, notice in time if it gets tangled under the boat or by the screw, and easily find its end if it accidentally falls overboard. Dark colors (black, dark blue) merge with the water and can cause an accident.
Do I need to lubricate the thread on the collapsible anchor?
Yes, if your anchor design involves disassembly or has movable threaded elements, it is recommended that they be lubricated periodically with graphite lubrication or WD-40, which will prevent metal parts from sticking to each other due to corrosion, especially after contact with salt water, and will allow you to quickly disassemble or fold the anchor at the right time.
Why doesn't the anchor hold the boat, even though it's heavy?
The problem is often the wrong angle of thrust, because if the falin is too short, it pulls the anchor vertically upwards, pulling it out of the ground, instead of pressing its legs horizontally, and the anchor can slide if its paw type does not match the bottom type (for example, a smooth cat on slippery clay), in which case it will help to increase the length of the falin or change the type of anchor.
