Inflatable boat requires a special approach to equipment, as any additional element on board must be not only functional, but also safe for cylinders. Anchor rum It is one of the key elements in enabling you to anchor or dock safely at shore, and the wrong choice or installation of this unit can lead to damage to cylinders, loss of anchor or even a water emergency.
Unlike hard cases, where mounts are often welded into metal, the PVC In boats, they use special structures that spread the load over a large area, which prevents tissue from rupturing and ensures that the connection is tight. Modern rims can withstand considerable effort, but their effectiveness depends on the quality of the installation and the correctness of the selected space on the deck.
In this article, we will discuss in detail what types of rims exist, how to choose them correctly for your model of the vessel and take a step-by-step look at the installation process. You will learn about the nuances of using various materials and understand why saving on this element can cost more than its qualitative replacement.
Design features and purpose of the anchor rim
The main function of the anchor beam is to create a reliable anchor point for the anchor beam. Construction It must withstand not only the static load of the anchor weight, but also the dynamic jerks that occur when wind or flow. Usually, a rump is a metal or plastic ring fixed on a base that is glued or screwed to a transom or deck.
The most important element is the presence of a roller or a smooth surface on which the rope rubs. If you just tie the anchor rope to the ring, it will quickly become overgrown, and when sampling the anchor, it will be difficult. roller made of stainless steel or durable plastic that facilitates the sliding of the cable.
The base of the rim, called a "pivet", must have sufficient area to be reliably glued to the cylinder or transom. The shape of the base varies: it can be round, oval or rectangular, depending on the place of installation and the manufacturer of the boat.
- 🔹 Metallic diamonds - are made of stainless steel or silumin, are highly durable, but can be heavier than analogues.
- 🔹 Plastic rips - light, do not rust, often have a built-in roller, but are inferior to the metal in the maximum load on the tear.
- 🔹 Combined models combine a metal ring with a plastic or aluminum base, optimizing weight and strength.
The choice between metal and plastic often depends on the size of the boat and the operating conditions. plasticFor more serious vessels, where the anchor can weigh 5-10 kg or more and the current is strong, it is preferable. stainless steel.
Selection criteria: material, load and compatibility
When buying a diamond, first pay attention to the stated workloadManufacturers often specify the limit value at which destruction occurs, but for safety you need to focus on values lower than 3-4 times. For boats up to 3 meters long, a model with a load of up to 100-150 kg is enough, and for boats over 4 meters it is better to take a safety margin of 300 kg and above.
Compatibility with the material of the boat is the second critical factor. PVCIf the boat has an inflatable floor NDP Or hard floorboard, the place of installation is chosen based on the availability of the transom part. Some rims are designed specifically for installation on the transmolor, others on board.
⚠️ Warning: Never use wooden or metal boats on inflatable vessels without special adaptations, and their design does not provide for load distribution on a soft surface, which is guaranteed to depressurize the cylinder.
You also need to consider the presence of additional features. For example, there are models with built-in features. holder For anchor rope, which allows you to compactly store the phala in a wound form. Other options have a rotary mechanism that allows you to change the angle of tension without skewing the base.
Preparation for installation: tools and materials
Quality installation of the diamond is impossible without proper surface preparation and the use of specialized chemistry. Clay. PVC must be two-component (polyurethane) because it creates an irreversible chemical compound, unlike single-component analogues, which only melt the top layer.
You'll need the minimum toolkit that any boat owner has to work with, and it's important to keep the surfaces glued clean and degreasing, because even microscopic dirt particles or fat can reduce adhesion at a rate of one.
- 🛠️ Solvent (acetone, white spirit or a special degreasing agent) - to clean PVC from dirt and factory lubricant.
- 🛠️ Sandpaper (grain content 100-200) - to create roughness (wounding) of the surface for better adhesion.
- 🛠️ Brush - hard, synthetic, for applying glue.
- 🛠️ Cargo - for pressing the smoke during drying (water cans, sand bags).
The ambient temperature also plays a role, and the optimal range for gluing is between +15 and +25 degrees Celsius, and at lower temperatures, the polymerization of the adhesive slows down, and at too high temperatures, it can grab ahead of time without providing the necessary strength.
Step-by-step instructions for installing the river on the transom
Installation of the dice on a transom is the most common option, because here the load is distributed on a hard or semi-rigid surface. The first step is to choose a place, it should be in the center of the transmuner or symmetrically, at a sufficient distance from the seams and valves, so as not to damage them when drilling (if the model involves fastening) or simply for an even distribution of weight.
Then there's the preparation process. The PVC surface and the base of the mug are thoroughly scrubbed with sandpaper until the matte appears. The glossy layer must be completely removed. The surfaces are then degreased with solvent. It's important not to touch the cleaned areas with your hands so as not to leave any fatty marks.
☑️ Checklist before gluing
The glue is applied in a thin, uniform layer on both glued surfaces. The technology requires you to wait a certain amount of time (usually 10-20 minutes, read the instructions on the glue jar) until the glue stops sticking to your fingers, then apply a second layer, hold for 5-10 minutes, after which the surfaces join.
The connection needs to be made quickly and accurately, because it's impossible to move the rum after contact without damage, and the gluing site is pressed very tightly and rolled by a hard roller or screwdriver handle from the center to the edges to drive out the air bubbles, and the load is placed on top.
| Phase | Action. | Drying time (about) |
|---|---|---|
| 1 | Applying the first layer of glue | 15-20 minutes. |
| 2 | Application of the second layer | 5-10 minutes |
| 3 | Connection and rolling | Instantly. |
| 4 | Complete polymerization | 24-48 hours |
Full operation of the boat is possible only after complete polymerization of the adhesive, which takes 24 to 48 hours depending on the humidity and temperature, and early loading on the adhesive that has not yet risen will lead to detachment of the rim under load.
Features of operation and care for the mounting unit
During operation, the anchor is exposed to aggressive water, ultraviolet light and mechanical friction. Periodically check the condition of the base: it should not be cracked, bloated or detached. Any change in the shape of the "petacus" signals overload or aging of the material.
The roller also requires attention. If it starts to jam or creak, it must be removed, cleaned of sand and silt, and smeared with water-repellent lubricant (for example, on a silicone basis), the jammed roller turns the creak into a regular ring, dramatically increasing the wear of the anchor rope.
⚠️ Note: Do not use conventional oils (motor, solidol) to lubricate the roller, as they can destroy the structure of PVC on contact or attract dust that will work as an abrasive.
After each release, especially in salt water, the pome is recommended to rinse with fresh water. The salt, drying, cryalizes and can damage the coating of metal or plastic, as well as accelerate the corrosion of fasteners (if any).
Common errors in selection and installation
One of the most common mistakes is to place the dice on the eye without marking, which can result in the flap rubbing against the pump valve, the seam of the balloon or the sharp angle of the transom, which will lead to rapid wear of the boat. Always try on the rope with a strained rope, simulating the work of the anchor.
Another mistake is using the wrong glue. Universal adhesives Or rubber adhesives that are not suitable for modern reinforced PVC, they create an elastic seam that, under constant stretch, just floats around and the fry comes off with a piece of fabric.
The need for reinforcement is also often ignored, and thin boats under the rim often put an additional patch of the same PVC material to increase the clutch area and distribute the load, especially for trans people who experience maximum stress when they are excited.
- ❌ Installation of the squirrel on a dirty or wet surface.
- ❌ Insufficient time of aging of glue between layers.
- ❌ Attempt to operate the boat before the full polymerization period.
- ❌ Use of the Rim for other purposes (for example, to tow another boat).
Remember that rum is a safety feature, and its reliability directly affects your ability to control the boat in difficult conditions, and you can't afford to save money on it or be negligent in installation.
Can I stick it on my own at home?
Yes, this is a real challenge for any boat owner, and the key is to follow the technology very strictly: cleaning, degreasing, double-layering, special glue, temperature control, no special equipment, except for the hair dryer and cargo, is required.
What is the maximum weight of the anchor will withstand a standard rum?
Standard PVC snails with sizes of 3-4 meters are usually designed to work with anchors weighing up to 10-15 kg. However, it is important to consider not the weight of the anchor, but the resistance force it creates.
What to do if the squirrels start to unplug?
Operating a boat with peeling crumb is prohibited, and the old glue must be completely stripped (mechanically), the surface must be cleaned to pure PVC, degreased and re-glued with rum, possibly strengthening the installation site with a larger patch.
