Going fishing or waterwalking without a reliable means of stopping is a risk that can cost you not only the catch, but also expensive equipment. Boat anchor It's a critical piece of equipment that keeps the crew and the craft safe in a variety of environments, whether it's a quiet lake or a river with fast currents. Many beginners make the mistake of relying on random objects like sandbags or old brake discs without understanding the physics of the process and the real loads on the hull.
Correctly selected and installed anchor This allows you to lock a boat at a given point, resisting wind and current, and in this article we will discuss in detail how to calculate the weight of a cargo, what types of anchors exist for different types of bottom, and why the length of the rope is more important than it seems at first glance. Safety at sea It starts with proper training.
Ignoring anchorage rules often leads to drifting in shallow water, rocks or, worst of all, under the propellers of passing boats. anchorage This will help you avoid these situations and feel confident even when the wind is getting stronger, so let's figure out what your boat needs.
⚠️ Attention: Using an insufficiently heavy anchor or a too short rope is the most common reason for a boat to de-anchor at the wrong time.
Calculation of anchor weight and type selection
The first thing a boat owner faces is the weight of the cargo, and there's a common misconception that the heavier, the better, but for inflatables. PVC Overweight can be a problem in transportation and storage. For the classical calculation of the mass of the anchor in kilograms, it is customary to use the formula where the weight of the boat is divided by 100, but this is only true for calm water.
If you plan to fish in rivers with the current or in windy regions, the mass should be increased. Gravitational anchor It operates by its weight, while paw models (e.g., Hall or Denforth anchor) use ground engagement to reduce their weight while maintaining efficiency. Inflatable boats up to 3 meters long are usually enough to carry a weight of 3-4 kg, whereas for metal or large PVC boats (4-5 meters) the weight can reach 7-10 kg.
It's important to consider not only the weight, but also the type of bottom. For mud, you need broad legs, for rocky, you need to be able to catch bumps, and for sand, you need the sharpness of the entrance. cat anchorIt does not always provide perfect grip on a solid bottom.
When choosing between a purchased product and a homemade one, remember the reliability of the materials. lead anchor or concrete can crumble or break when hit by stones, whereas factory models made of stainless steel or galvanized iron undergo rigorous tear and corrosion tests.
Types of anchors for different conditions
The market offers many designs, each of which is sharpened for specific tasks. Cat anchor It remains the leader among inflatable boat owners due to its folding design and versatility, it is easy to retrieve in a hazelnut and is suitable for most types of soil, although on a very hard slurry bottom it can simply slide over the surface.
A more advanced option is anchorIt has great holding power on sand and clay, thanks to its two wide legs, but it has a significant drawback: it doesn't work well on grassy bottoms or where there are lots of rocks, because the legs can't reach the ground, and it also requires more storage space.
For professionals and lovers of trophy fishing is interesting fungus-anchorIt's perfect for a muddy bottom, where it's sucked in like a cork, giving it a dead grip, but it can be extremely difficult to pull it out of there without a special sampling mechanism, which makes it less popular with fast-fishing enthusiasts.
The secret to Denforth's anchor success
The main element of Denforth's design is the transom bar at the bottom, which causes the paws to stick into the ground at an optimal angle. If the bar is deformed, the anchor will not work.
And we must not forget that anchorage They're not used to stop, but to braking drift and keep the boat nose to the wave, and they're an indispensable safety tool in stormy weather when you have to wait out the weather.
Anchor rope: length, material and tooling
Even the heaviest and most tenacious anchor will not work if it is tied with a short rope. The basic rule is that the rope length must be 3-4 times the depth in the parking lot. This is necessary so that the thrust force acts horizontally, pressing the anchor's legs to the bottom, rather than pulling them up. nylon-fail preferably, since it has elasticity and extinguishes the jerks of the boat on the wave.
The chain as a continuation of the rope (the so-called "cat stop") is used on large boats, but for small boats, a strong rope with a diameter of 6-8 mm is enough. Polypropylene cord cheap and does not sink, but quickly rubbed, whereas the capron phala is stronger, but requires careful handling so as not to injure the hands during the sampling.
Always tie a thin safety rope (a cutaway molt) to the anchor ring. If the anchor jams in the rocks by pulling that rope, you turn it over and release it without diving.
The rope attachment to the boat should be reliable. Anchor rum It should be set so that the boat does not turn over when it snags. It is best to attach the phala to the bow dip, passing it through the duck for fixation. Never tie the anchor end to parts that may not withstand a jerk, such as a guardrail or handles.
Armor setting and sampling techniques
The anchoring process requires a sequence of actions: first, the boat goes to the chosen place against the current or the wind, the engine is silenced, and the boat is allowed to slowly return, at which point the anchor is smoothly lowered to the bottom, controlling the unwinding of the rope, a sharp throw of the anchor can confuse the tangle around the screw or damage the bottom.
When the required length is given, the thack is pulled and fixed on the duck, the boat should turn its nose against the elements, if the boat turns sideways, then the anchor is not caught or the current is too strong for a given weight of cargo, in which case the procedure is repeated by adding the length of the rope or changing place.
☑️ The algorithm of correct formulation
The anchor is sampled only after the boat has reached a point above the anchor. It is dangerous to pull the anchor at the limit while sitting in the boat, you can lose your balance and fall overboard. If the anchor is dead, use the method of brute force of arms, pulling the boat to the anchor, not the anchor to the boat.
Comparative table of specifications of anchors
To make it easier to choose, let's look at the basic parameters of popular models in a comparative table, and the data will help you navigate the ratio of weight, strength and applicability.
| Type of anchor | Weight (kg) | Type of bottom | Holding power |
|---|---|---|---|
| Cat folding. | 2-5 | Universal. | Medium |
| denforth | 3-6 | Sand, silt | High. |
| fungus | 4-8 | Il, clay | Very high. |
| Plow (USA) | 5-10 | Sand, rock | High. |
| Sandbag | Anyone. | il | Low. |
As you can see from the table, cat anchor It loses to specialized models in holding power, but wins in compactness. Plow anchors. (CQRs) work well on a rocky bottom, but are harder to transport, and the choice is always up to the user depending on the operating conditions.
Security and frequent errors
One of the most dangerous mistakes is to tie the anchor end to the transom of an inflated boat, and in strong currents or winds, the boat can turn around and pull water over the side, leading to a rollover. Anchor rum It should be strictly in the nose, and it is also dangerous to wind the end on the arm, which, if you jerk abruptly, can cause serious injury or pull a person overboard.
⚠️ Warning: Never tie an anchor phala to the transom of an inflatable boat! it's a guaranteed way to flip over on a wave or current.
Another problem is the use of rotten or parched ropes. Natural fibres They lose strength quickly, and an old chapron can burst at the most inopportune moment. Regularly check the condition of the falt for scuffs and knots that reduce strength by 40-50%.
The safety principle is that the anchor should hold the boat, not the boat anchor, and if the boat is stronger than the anchor, you swim, not stand.
Don't forget to use the signal lights if you're planning an overnight stay at anchor, and the rules are that the anchored vessel should be visible to other traffic participants. anchor-fire A white round fire can cause a collision in the dark.
Care and storage of equipment
After every fishing trip, especially on salt water, the anchor and rope must be washed with fresh water, and metal parts, even if galvanized, are susceptible to corrosion. Rust Not only does it spoil the appearance, but it also weakens the structure, making the metal brittle. Periodically lubricate the moving parts of folding anchors (for example, cats) with graphite lubricant or oil.
The rope should be stored in a dry, ventilated place, rolled up in coves, soaked in a sealed synthetic faal can begin to vent and lose its properties. Anchor system The collection takes up a little space if you use folding models, which is especially important for owners of small cars.
How to calculate the length of the rope for a depth of 5 meters?
For a depth of 5 meters, the minimum length of the rope should be 15-20 meters (ratio 1:3 or 1:4). It is better to have a reserve of 30 meters, since the bottom relief can be unpredictable, and the current carries the boat farther from the point of production.
What if the anchor is stuck dead?
Don't pull the boat sharply. Try to approach the anchor from different angles, changing the angle of thrust. If you have a thrust line, use it. In extreme cases, you have to dive, but only if it is safe and visible.
Can a car drive be used as an anchor?
It's possible, but it's not efficient. It's a very sailing disk, it doesn't get well into the ground, it's holding power is much lower than a specialized anchor of the same weight, it's a fishless version.
Which color is the best rope?
Bright colors (orange, yellow) are better visible on the water and will not be lost if they fall overboard, but the white or blue rope is less noticeable in the water, which is important so as not to frighten the fish and not interfere with the view, but it is easier to lose.
Do I need an anchor in shallow water?
In shallow water, a boat can blow up rocks or reeds, where it is difficult to get out without damaging the bottom, anchoring the position even at a depth of 0.5-1 meters.
