Every inflatable swimmer must securely anchor a vessel on the water sooner or later. Anchorage is not just a comfort, but a safety issue, especially when fishing in windy weather or on the current. However, regular components are often not strong enough or simply absent from the basic version of budget models, which is why installing an additional anchor ditch is becoming one of the most popular improvements.
The installation process requires precision, understanding of cylinder design and the right materials selection. An error in the planning or selection of adhesive can lead to loss of leakage. PVC fabricThis article will cover all the steps from the selection of the location to the final test of the strength of the attachment.
Many beginners are afraid to drill or stick elements to the sides for fear of ruining expensive property. However, following proven technologies and using specialized two-component compounds, you can create a knot that will withstand loads even in extreme conditions, the main thing is to take your time and carefully prepare the surface.
Choosing the optimal place to install a rim bolt
The first and critical step is to determine the mounting point, and the wrong location can cause the boat to turn sideways to the wave, which significantly reduces stability and increases risk. overquill Ideally, the anchor rim should be positioned on the bow force, strictly on the diametrical plane of the vessel.
If you have a boat design frigate or hunter It's often tempting to attach the bar directly to the bar, but that's not always true in terms of hydrodynamics. When you push the anchor tile, the bow of the boat should dive into the water, cutting the wave, not picking it up, so the center of the mount should be as low and close to the keel as possible.
- 📍 Nasal reinforcement: The classic version, ensuring the correct position of the vessel relative to the anchor chain.
- ⚓ The trunk section: It is rarely used, mainly for mounting a second anchor when anchoring "in the stretch" on a strong current.
- 🛡️ The tailbar: The design of the boat does not have a nose cone, but requires additional washers to distribute the load.
⚠️ Warning: Never install a bolt on the soft part of the cylinder without a hard insert or a special plastic nickel. The point load from the metal bolt will inevitably cause the PVC tissue to rupture under pressure.
Also consider the length of your anchor shaft and the depth of the water bodies where you plan to fish. If you often use a boat in shallow water, the angle of departure of the shaft will be sharper, which creates a greater horizontal load on the fastener. quilt.
Required tools and materials
The quality of the result depends on preparation. You will need not only the flap bolt itself, but also a number of specific materials that ensure tightness and strength of the joint. Conventional building adhesive or sealant will not work here, because they do not have the necessary elasticity and adhesion to polyvinyl chloride.
The main binder should be a two-component polyurethane adhesive, specially designed for PVC boats. Texacol or RadicalAfter polymerization, you create a seam that is as strong as the boat material itself, and it's also important to buy a degreasing agent, preferably acetone or a specialized solvent for PVC.
Always check the shelf life of the glue before starting work. Open two-component composition is not stored for long, and expired glue will not provide the necessary tightness of the seam.
For mechanical fixation (if you choose through mounting), you will need stainless steel or brass. Conventional steel quickly rusts, oxidizes and spoils the appearance of the boat, and can also cause corrosion destruction of fabric.
Below is a table that helps you choose the diameter of the fastener depending on the displacement of the boat:
| Boat class (cm) | Bolt diameter (mm) | Scrap bolt material | Recommended load (kg) |
|---|---|---|---|
| 280 | M6 | AISI 304 Stainless Steel | 150 |
| 280 - 320 | M8 | Stainless steel AISI 316 | 250 |
| 320 - 360 | M8 - M10 | Brass/Stainless steel | 400 |
| 360 | M10 - M12 | Stainless steel AISI 316 | more than 500 |
Don't forget to prepare P120-P180 sandpaper for gluing surfaces and dryer for thermoactivation of the adhesive. Using a building hair dryer allows the adhesive to be heated to the desired temperature, ensuring maximum diffusion of adhesive molecules into the structure. PVC fabric.
Technology of gluing a penny under a bolt-rim
The most reliable and common method of installation is to glue a special plastic pen (plaza) with a bolt hole already installed or intended, which distributes the load over a large area of the cylinder, preventing deformation, the process requires cleanliness and temperature.
First, carefully degrease the installation site on the boat and the back of the penny. Rub the surface with a rag soaked in acetone until the cloth no longer has traces of dirt or factory lubrication. Then smear both surfaces until the mat appears - this will increase the contact area for the glue.
☑️ Preparation for gluing
The adhesive is applied with a brush in two layers. The first layer must be absorbed into the material structure, so it is applied thinly and allowed to dry completely (usually 10-15 minutes, but it is better to focus on the instructions for a particular brand). The second layer is applied more abundantly and immediately warmed by a hairdryer to a temperature of about 50-60 degrees Celsius. The surfaces become sticky but do not flow.
When you connect the pen to the balloon, you need to roll the glue place from the center to the edges with a roller carefully, so that you squeeze out all the air bubbles, the pressure should be uniform, and then you want to load the structure with a sandbag or cans of water for 24 hours until you completely polymerize the composition.
Through installation: drilling and sealing
The through-drill option is used when maximum reliability is required, for example, on large type boats. Cayman. or Solar.In this case, the bolt goes through the cylinder, and the tightness is ensured by rubber gaskets and adhesive layer, a riskier method that requires high accuracy.
The hole can only be drilled after the adhesive pen has completely dried. The drill should be sharp, and the diameter of the hole should correspond to the diameter of the bolt with minimal clearance. It is important to prevent the edges of the hole from melting when drilling, so work at low drill speeds.
⚠️ Attention: When you install through, be sure to use cone rubber washers. They work like glands: when you pull the anchor rope, the puck presses against the hole, increasing the sealing, rather than breaking it.
Once the bolt is installed, the entry and exit of the fastener is laced with glue, so don't spare the material, it should form an elastic "collar" around the metal, which will prevent moisture from entering between the metal and the plastic, which could lead to tissue stratification when water freezes in winter.
To strengthen the design, the "sandwich" method is often used, when a PVC response plate is also glued to the inside of the balloon. This allows you to clamping the fabric between two hard surfaces, eliminating its rubbing against metal when rolling.
Installation of the anchor ring on the transom
Although the main snare is on the nose, mounting an additional ring on a transom can be useful for anchoring when moving or for anchoring stern to wave (sometimes required for catching certain fish).
The transom plate is usually made of plywood or plastic, so drilling here is less risky for the tightness of the cylinders if the mount is outside the inflatable part. However, if you attach the mount directly to the soft part of the transom cylinder, the technology is similar to the nose installation.
It is important to consider that the load on the transom ram when moving a boat with an anchor can be dynamic and very high. So use bolts with a diameter of at least M8 and be sure to fix the nuts with growers or self-contradicting nuts so that the vibration of the engine does not weaken the connection.
The secret of durability of translating fastening
When you install the river on a tray, treat the bolt thread with graphite lubricant before you screw the nut, which will prevent the metal from boiling and make it easy to disassemble the knot after a few seasons.
Some boat models, such as Master. or brigThey have special pockets or reinforcements in the transom area, and use them if they are designed, so that you don't have to drill new holes and you keep the factory warranty on the product.
Testing and operating rules
Once the glue has been fully polymerized (at least 24-48 hours), you need to do a visual inspection and initial testing. Try to pull the installed crumb in different directions. You should not hear the crack of the adhesive being removed or you can see the movement of the pencil relative to the balloon.
The first load test is best done on the shore, tying the boat to a tree or a heavy object and gradually pulling the tile. If the structure has withstood jerks on land, you can go to water tests. Remember that on water, the effort increases many times due to the inertia of the water mass.
- 🔍 Visual control: Check the glue condition around the pencil regularly, especially after winter storage.
- 💧 Leakproofness test: The pumped boat must keep the pressure; the soap solution will help to find micro-tampering at the bolt.
- 🧼 Gone: After each release, wash the metal parts with freshwater to wash off the salt and silt.
Keeping up with the rules will prolong your life, avoid being hit by rocks or concrete piers, and if the boat is used in salt water, the service frequency of the metal elements should be doubled.
A well-established anchor rump serves as much as the boat itself, if the correct glue is used and the surface preparation technology is observed.
Frequently Asked Questions (FAQ)
Can you use a conventional car sealant instead of a special glue for PVC?
No, absolutely not. Car sealants don't have adhesion to polyvinyl chloride and they don't have the necessary elasticity, and when you load them, they just peel off, and you lose the airtightness of the balloon. Only use two-component polyurethane adhesives for boats.
How long after installation can the boat be launched?
The minimum time for primary polymerization is 24 hours at a temperature of +20°C. However, it is recommended to wait 48-72 hours for full strength and reliability, especially if the installation was carried out at low temperatures or high humidity.
What to do if the squirrel began to peel off during operation?
Stop using the boat immediately under load. Lower the air, clean the area thoroughly of old glue and dirt, hide the surfaces and re-glue with all technological processes. Operating with a damaged mount is dangerous.
Do I need to lubricate the bolt thread before installation?
A lubricant (e.g., lithium or graphite) prevents corrosion grip of the thread, protects against moisture entering the compound, and makes it easy to dismantle the unit in the future for replacement or maintenance.
