Inflatable swimming facilities require a special approach to equipment, especially when it comes to fixing on site. PVC boat frog It is not just an accessory, but a critical element to ensure the safety of the vessel and the comfort of the crew during fishing or recreation. Unlike heavy metal anchors, which can damage cylinders if handled carelessly, specialized folding structures solve the problem of storage and operation.
The choice of a suitable model depends on many factors: the type of bottom of the reservoir, the size of the vessel and the strength of the wind. Incorrectly selected device can lead to the demolition of the boat in the fairway or, conversely, to the inability to quickly remove the boat from anchor. Cat anchor classic anchor-frog There are fundamental differences in design that must be considered when buying.
In this article, we will discuss in detail the design features, materials of manufacture and nuances of installation of anchors for such anchors. The opening angle of the paws in 60-70 degrees is optimal for hooking on a stony or slurry bottomHow to avoid typical beginner mistakes.
Design features of the anchor frog
Classical anchor-frog It's a monolithic or welded structure that looks like an inverted pyramid with paws. The main difference from other types of anchors is the way the legs are hooked: the paws work like claws, digging into the ground when the rope is pulled. Inflatable boats are important dimensions of the device, because it must be compact and not have sharp edges that can pierce the device. PVC fabric.
The weight of the product directly affects the holding power. For boats up to 3 meters in length, a device weighing 1.5-2 kg is usually enough, while for more overall models (3.5-4 meters) a weighted version of up to 3-4 kg will be required. pyre (rings) for mounting the phall: it must be reliably welded or cast together with the hull to prevent loss of anchor at a critical moment.
⚠️ Note: When buying, pay attention to the quality of welds. Uneven metal welding can damage the fabric of the boat when laid carelessly, so always use a protective cover or bag.
Some models are equipped with additional elements, such as folding paws to improve transportability, but the solid versions are considered more reliable, since there is nothing to break in them. Galvanic coating or high-quality painting protects the product from corrosion, which is especially important when used in salt water.
Materials of manufacture: steel, cast iron or lead
The durability and efficiency of an anchor depend on the material it is made of. steel St3 These products are highly durable and relatively low cost, but require careful maintenance after each operation to avoid rusting.
Cast iron frogs are heavier at the same size, which provides better initial fixation at the bottom. However, cast iron is more fragile: when hitting stones, the paws can crack. Lead models are less common because of the high cost, but they are ideal for the use of the metal. flyboatLead is softer and less dangerous in accidental contact with the sides.
- 🔩 Steel is durable, cheap, but is subject to corrosion without coating.
- 🏗️ Cast iron is heavy, holds well, but can split on impact.
- ⚖️ Lead is safe for PVC, very heavy, expensive.
- 🛡️ Stainless steel is ideal, but it is extremely rare in mass production because of the price.
The coating also plays a role. Epoxy paints hold better than normal nitro-emal, but over time they wear off against the stones. Hot galvanizing It's the best protection option that lasts for years, and if you're planning to fish on rocky rivers, you should go for models with thickened paws.
Comparison of frog and cat anchor
Often, newcomers get confused anchor-frog and cat-anchorThe cat has folding legs (usually 4 or 6) that press against the central spindle, which makes it very compact to transport, but less reliable on stained or heavily overgrown bottoms, where the legs can simply slide over the surface.
The frog, in turn, has a fixed angle of opening of its legs, which guarantees instant hooking, and it works better on current and wind, because the structure tends to burrow into the ground, rather than just catching on to it. PVC boats The cat can be more dangerous because of the movable sharp elements, which are more difficult to control when styling.
| Characterization | Anchor frog | Cat anchor |
|---|---|---|
| Construction | monolithic | Folding paws |
| Engagement | Tall (stones, silt, grass) | Medium (better on stones) |
| Safety for PVC | High (if there is a cover) | Low (many sharp ends) |
| Transportability | Medium | Great. |
Can a boat anchor be used for an inflatable boat?
It is strongly discouraged to use a full-fledged boat anchor (such as admiralty anchor) on a PVC boat. In addition to its heavy weight, it has sharp horns that are guaranteed to damage cylinders if handled carelessly, and its holding power is excessive for light boats.
When choosing between these two types, use the environment. If you fish fast or in areas with dense vegetation, the frog will be more reliable. For rare trips to calm water and the need for maximum compactness, you can consider the cat, but with caution.
Installation of anchor anchorages on the boat
The proper organization of the anchorage is a guarantee of safety, you can't just throw the anchor to the bottom of the boat, because when you jerk it can break through the cylinder or fly overboard with the flap. anchor-bolt The anchorage should be in the bow, strictly in the center or with a slight shift, so that the boat does not turn sideways to the wave.
To install the bolt in a tray board or inflated balloon (if a special holder is used), a hole is drilled. In the case of inflatable elements, special pads are used, made of durable rubber, which are glued to the cylinder. two-componentPVC, and allow it to be completely polymerized before loading.
☑️ Checking the anchor assembly's readiness
⚠️ Warning: Never tie the phala directly to an inflated cylinder without a special protective pad. Friction of the rope under load instantly heats and melts the material, leading to depressurization.
If the boat is equipped squirt-boardThe ram can be mounted directly on it, but make sure the board can withstand the jerk. For large boats, it is advisable to use an anchor bracket that takes the mounting point outside the side, preventing the rope from friction against the cylinder.
Rules for safe anchoring
The anchoring process requires a sequence of actions: first the boat is brought against the current or wind, then the anchor is dropped, and only then the tile is ejected. The anchor end should be at least 3-4 depths in the parking lot to provide the necessary tension angle for the hook of the paws.
Use of use buyrepa And if you're anchoring in a rocky bottom or a snag, if you're anchoring the main anchor, you can pull it back and you can pull it out without diving. frogThose who like to cling to stones.
- 🚣 Always carry a sharp knife attached to the boat in case of need to cut the falt.
- 🌊 Consider the tide or change in water level due to the operation of the hydroelectric power station, so that the boat is not carried away in shallow water or dragged to depth.
- 🧶 Use a flap made of a floating cord (polypropylene) so that if lost, it can be seen and picked up.
You need to pull the boat off the anchor, you need to jerk back from the direction of the hook. If the anchor is sitting dead, don't pull the boat forward, it can turn it over. It's better to go around the parking lot and pull in the opposite direction.
To quickly recoil the anchor from the depths, tie a thin line to its spindle (upper part), which will go to the float on the surface, which will allow you to turn the anchor and release it from the hook in one movement.
Accessory maintenance and storage
Metallic products require maintenance, especially after contact with salt water. anchor-frog You have to wash it with fresh water and dry it, and even galvanized coatings lose their properties over time, and corrosion can start at the welds.
Keep the anchor in a dry place, preferably in a separate bag of dense fabric, this will not only protect the anchor itself, but also protect the rest of the things in the boat from dirt and rust. pyre And the place of attachment of the rope: the metal can be rubbed or oxidized.
⚠️ Warning: Do not keep a wet anchor in a closed backpack or a boat bag. Humidity will lead to rapid development of rust, which can spread to the metal elements of the boat itself (furniture, fun switches).
If corrosion is found on the surface, clean it with a metal brush and coat it with corrosion-resistant compound or paint, and regular maintenance will extend the life of the accessory for decades.
The main principle of safety on the water is the reliability of the anchor system, saving on the quality of the anchor or disregarding the rules of its installation can cost you boats or even your life.
What weight anchor to choose for a boat 3 meters long?
For a 3-meter inflatable boat with a crew of two, the optimal weight of the anchor is in the range of 2.0-2.5 kg. This will ensure reliable parking in moderate winds and currents. If you plan to fish alone in calm water, you can limit yourself to 1.5 kg.
Can an anchor frog be used on a strong current?
Yes, the design of the thigh has proven itself well on the current, as it tends to burrow into the ground. However, for rivers with a rapid flow (more than 1.5 m / s), it is recommended to use an anchor with a margin of weight or use two anchors mounted from the nose and aft (in tension).
How to replace an anchor frog in an emergency?
As a last resort, you can use a bag of rocks or sand tied to a rope, and this improvised anchor has good holding power at any bottom, but it is heavy to transport and is not designed for repeated use.
