Inflatable watercraft owners often underestimate the importance of reliable water supply. anchorageYou can rely on a boulder tied to your nose or a sandbag, but a quiet fishing or a rest on the water depends on how confidently your boat is when the wind is amplified or the current is in the right place. anchorage It can lead to drifting into the fairway, rupture of gear or even turning the boat over in stormy weather.
In this article, we will discuss in detail the physics of the retention process, help calculate the optimal weight of the cargo and choose a design that will not damage. PVC tubesYou'll learn why classic cat's paw can be dangerous for inflatables and what modern solutions the market offers. parachute-anchor or drake You will feel confident even in an unfamiliar water.
Before we move on to specific models, we must realize that anchor It's not just a load, it's a complex mechanism for interacting with the bottom, and the retention rate depends on the angle of the thrust, the length of the rope, and of course the weight, and ignoring those factors turns the anchor into a lottery, where losing can cost expensive equipment or safety.
Calculation of weight of anchor for PVC boats
The first mistake of beginners is to buy an anchor that is too heavy just in case. flyboat The problem is that overweight is dangerous primarily for transom and sides, and it also makes it difficult to sample gear. There is an empirical formula that allows you to determine the minimum mass required: the weight of the anchor should be approximately 10% of the displacement of the boat.
For standard two-seater models up to 3 meters in length, a weight of 3-4 kilograms is enough. boat (3.2-3.6 m), the best solution would be an anchor weighing 5-6 kg. Flagship or Cayman. length of more than 4 meters, require 7-8 kg or more, especially if you plan to fish on the course.
It is important to consider not only the length, but also the sailing of your boat. The high sides and the installed awning significantly increase the wind load, requiring heavier loads. anchorageAt the same time, in a strong current, the decisive factor is not so much weight as the shape of the anchor, which ensures the engagement of the bottom soil.
Below is a table that helps to orient in the choice of mass depending on the dimensions of the boat:
| Boat length (m) | Recommended weight (kg) | Typical models | Conditions of operation |
|---|---|---|---|
| 3.0 | 3 - 4 | Aqua, frigate-300 | Lake, weak current |
| 3.0 - 3.6 | 5 - 6 | Master, Orca 360 | River, middle course |
| 3.6 - 4.2 | 7 - 9 | Flagship 420, Solar | Reservoir, wind |
| more than 4.2 | 10+ | PVC catamarans | Open water, storm |
Remember, the weight is for classic metal anchors. anchor-chain Or combinations, the calculation can vary. It's always better to have a small margin of traction, but not overload the mass of the product itself.
Types of anchors: from classics to modern developments
The market offers many designs, but not all of them are suitable for PVC boatsThe traditional cat anchor, which consists of a central rod and four folding legs, is the most popular because of its compactness. However, it has a serious drawback: the sharp edges of the legs can easily pierce a balloon in a sloppy sample or on the wave.
A safer option is considered to be anchor It's a flat heel design that provides great engagement on the sandy and slurry bottoms, and the paws are often protected by plastic linings or rounded, minimizing the risk of damage. material of the boat.
- 🪂 Anchor-parachute (Drift Anchor): Ideal for braking the demolition of a boat by wind or current, works in the water column without touching the bottom.
- ⚓ Gravitational anchor: Simple load (pancake, weight), which holds solely at the expense of mass; good on a rocky bottom, where engagement is impossible.
- 🐙 Octopus anchor: Folding structure with soft or rounded paws, specially designed for inflatable vessels.
⚠️ Attention: Never use anchors with sharp teeth or rusty surfaces without pre-treatment and protection. Any barb on metal when you pull a rope works like a knife for your PVC.
Special attention deserves They're very convenient for transport in the trunk of a passenger car, but they require careful assembly before they get on the water, and the reliability of the joints in these models is a critical parameter that you need to check before every fishing trip.
Specificity of the parachute anchor for PVC boats
Anchor-parachuteThe drift anchor, or drift anchor, is a cone-shaped device made of strong fabric that opens up in the water under the pressure of a stream. Unlike bottom anchors, it does not lie on the ground, but creates a powerful hydrodynamic resistance, which allows the boat to not lag to the wave, but gently turn its nose against the current or wind.
Use of use drift-anchor This is especially true when trolling or spinning in windy weather, and it stabilizes the boat, keeping it from cluttering around, and it reduces the risk of waves flooding through the side. PVC It is also a way to avoid impacts on the hard bottom relief, since the anchor-parachute works in the water column.
The size of the parachute is strictly the length of the vessel. Too large a cone can put excessive strain on the dice and transoms, especially when jerking. Too small simply will not perform its stabilization function. Usually for boats 3-4 meters long, models with a diameter of 60-90 cm are used.
How to properly store the anchor-parachute?
After use, the fabric must be thoroughly washed with fresh water (especially after fishing at sea or in flowering water) and dried in the shade. You can not fold a wet parachute - the fabric can sprinkle, and metal rings can rust. It is better to store it in a straightened form or in a free bag.
An important element of the system is fella A parachute anchor uses a floating cord to avoid getting tangled in the engine propeller, and the phala is typically 2-3 lengths of the boat hull, but can be adjusted depending on the wind.
Schemes of anchoring: nose, stern or board?
The correct anchoring scheme is a safety issue, and the classic rule is: anchor is always placed from the noseThis allows the boat to stand up with its nose against the wave and wind, which is the most stable and safe position for any vessel, including the boat. flyboat.
Anchoring from the stern is not recommended for PVC boats. In this position, the boat turns to the wave with a flat transom, which dramatically increases the risk of flooding the water into the cylinders and subsequent rollover. In addition, the load on the transmolator plate may exceed the permissible values, damage to the anchorages.
But there is a two-anchor scheme, where one anchor is placed from the bow and the other from the stern, which is necessary to fix the boat in a narrow riverbed or in a strong lateral wind, in which case the boat is rigidly fixed at the course, but this scheme requires experienced handling and reliable anchor-royme both ends.
- 🌊 From the bow: The basic and safest circuit, the boat cuts the wave with a sharp nose.
- ⚓ In stretching (nose + stern): For current and wind from different directions, it requires caution.
- 🛑 From the stern: Prohibited from PVC boats in the wave, high risk of tipping over.
When choosing a mounting point on the nose, it is important to use regular swan-robs Or special ducks, located as close as possible to the longitudinal axis of the boat, anchoring to the handle for carrying or to the elements of the soft bottom is unacceptable - the load can tear these elements.
Equipment: rope, rim-gak and chain
The anchor itself is only half the story. The other half is the anchor. anchorageFor PVC boats, use is critical squirrel This device is mounted on the nose and allows you to choose the anchor without dragging a dirty, wet rope and the anchor itself through the side, risking damage to the balloon.
The best way to use the foal is a synthetic cord (nylon, polypropylene) with a diameter of 6-8 mm. Nylon is good for its elasticity, it extinguishes jerks, but absorbs water. Polypropylene does not sink or absorb moisture, but is less durable at small diameters. The optimal length of the rope is 30-40 meters, wound on a compact motif.
☑️ Checking the anchor system before exit
The use of a short chain (3-5 meters) between the anchor and the rope makes a double sense. First, the chain weight presses the lower part of the anchor to the ground, improving engagement. Second, it weights the lower part of the system, changing the angle of attack of the paws. However, for light PVC boats, the weight of the chain should be minimal, so as not to overload the nose.
⚠️ Attention: When sampling an anchor on a PVC boat, never wrap a rope around your arm! With a sharp jerk or boat course, this can lead to serious brush injury or even pulling a person overboard. Use gloves and reel.
Safety and maintenance
The operation of the anchor equipment requires regular maintenance. After every fishing, especially in salt water, the anchor and rope must be washed with fresh water. The metal parts should be lubricated to prevent corrosion, which over time reduces strength. anchorage.
Pay special attention to the places where the rope is attached to the anchor. The knots should be reliable (for example, "bulin" or "bayonet"), and the brackets are tightly tightened and, preferably, pinned or wrapped with tape so as not to scratch the boat. Regularly check the condition. anchor-royme on the hull of the boat – they should not hang around or have cracks around the base.
Keep the anchor separate from the boat, if possible, or in a special hard case. PVC boats during transportation. Gravel or sand left in the folds of the anchor-cat act as an abrasive when rolling.
Keeping these simple rules will prolong your life and ensure safety on the water, and remember that in an emergency, it is the reliability of the anchor system that can be decisive.
The safety of PVC boats at anchor depends not so much on the weight of the anchor, but on the correct layout (only from the nose!) and the availability of a rim-gac for safe sampling.
Frequently Asked Questions (FAQ)
Can I use a sandbag or stone instead of an anchor?
You can only use it as a temporary measure in calm at a shallow depth, the bag has no paws to hook and only holds it by weight, and when the wind is amplified or the current is running, it easily breaks off, and it starts dragging along the bottom without performing its function. anchorBesides, a wet bag is very hard to lift on board.
How long should the rope be for the anchor?
The length of the rope (fala) should be 3-5 times the maximum depth at the fishing site, this is necessary so that the anchor lies on the bottom, and not hanging in the water column at an angle. Standard stock for universal use is 30 meters.
What to do if the anchor is stuck at the bottom?
Don't pull the boat abruptly, it can damage the trawler or the cylinders. Try to walk around the parking lot, changing the direction of the thrust. squirrel-gagIf you want to push the rope through it, pull it at a different angle, and if you want to pull it at the top, if you want to push it around, you can use a scaffold to pull it out of the top.
Do I need to lubricate the anchor before storage?
Metal anchors are susceptible to corrosion, and after drying, it is recommended to wipe them with rags with oil or special lubrication, which will prevent rust, which not only spoils the view, but also reduces the strength of the metal, and also soils the boat and clothes.
