Quality preparation of the swimming means for the season is impossible without attention to details, among which PVC-boat-holder It's a central place, and it's the reliability of the connection that not only makes it easier to go fishing or cruising, but also makes it easier to get on board, and the water element doesn't forgive mistakes, so the choice of fittings becomes a matter of paramount importance for every inflatable vessel owner.
The modern market offers many solutions, from simple screws to complex systems of rapid installation, designed specifically for work with reinforced materials. PVC fabricThe squirrels used in boats have a specific structure that requires special treatment in drilling and fixing elements. Incorrectly selected metallic metal can damage the sealed layer or crumble under the influence of vibration and salt water.
In this article, we will discuss in detail the types of fasteners, their purpose and installation technologies so that you can properly equip your boat. Understanding the physics of processes and the properties of materials will avoid common errors and prolong the life of your boat. floater.
Materials and requirements for marine fasteners
Aggressive aqueous environments, constant UV exposure and mechanical stresses dictate stringent material requirements, and the main enemy of metal parts is corrosion, which can destroy even strong steel in one season. stainless steel AISI 304 and AISI 316 are considered the gold standard in shipbuilding.
However, not all elements need to be metallic, and high-strength polymers and composites are often used to reduce weight and avoid galvanic corrosion. Silumin (aluminum-silicon alloy) is also popular for its lightness, but it is more fragile and susceptible to oxidation in salt water compared to quality stainless steel.
When choosing fittings, it is important to pay attention not only to the material of the part itself, but also to the quality of the coating of threaded joints. Galvanic galvanic galvanic can provide temporary protection, but for constant contact with water, it is better to choose products made of solid corrosion resistant material.
- 🛡️ Stainless steel AISI 316 Maximum resistance to salt water and acids.
- 🧱 Silumin Easy and cheap option suitable for fresh water.
- 🌊 Brass and bronze Excellent corrosion resistance, but high cost and weight.
- 🔩 Galvanized steel Budgetary solution that requires careful care and drying.
The use of ferrous metal without coating is categorically not recommended, since rust not only destroys the fastener, but also stains the sides of the boat, leaving hard-to-remove traces.
⚠️ Never mix dissimilar metals (such as steel bolts and aluminum plates) without insulating pads, otherwise an electrochemical reaction will destroy the less noble metal in a matter of weeks.
Fixing of the transom board and attachments
The tray board takes on the maximum load from the outboard motor, so its mounting must be absolutely reliable. screw-trap It's important that the fastener cap has no sharp edges that could damage the cylinders if handled carelessly.
For installation of transom on inflatable boats are often used quilt In the case of hard inserts, the fasteners pass through reinforced areas of PVC, which requires precise timing of the length of the screw, and a screw screw that is too long can pierce the inner layer of tissue or even hit the balloon.
In the installation of attachments, such as rod holders or sonar holders, often use transition plates, which distribute the point load from one bolt to a large area, preventing the thrust and deformation of the material on the board.
- 🔨 Use it. press-puck for a tight fit without damaging the material.
- 📏 Precisely calculate the length of the thread so as not to damage the opposite side.
- 🔒 Apply lock nuts or a thread fixer to prevent spontaneous unwinding from vibration.
Particular attention should be paid to the angles of attachment. In these areas, the material experiences the greatest tension, so installing additional reinforcing elements (pyataks) from the same PVC material is a mandatory procedure.
Installation of seats (cans) and sleigh
The organization of the interior space of the boat is impossible without reliable seats. PVC boat banks Removable options are usually based on special attachments attached to cylinders or fixed in sleigh slots, fixed seats are attached directly to the bottom or sides through reinforced areas.
For installation of supports under banks are used penny-pocket It's a round or oval piece of PVC tissue that sticks to the balloon, and it's in the middle of the pen that the fastener is screwed in, and it allows you to spread the load and avoid tearing the tissue at the attachment point, and if you don't have a pentacle, you can't drill or screw anything into the balloon.
When gluing pentacles, be sure to degrease the surface with alcohol or a special PVC cleaner, otherwise the fastening can come off together with a piece of fabric under load.
Slate (floor) also requires fixation, especially on inflatable floor boats (BBBs), which use special locks, Velcro straps or pin joints that prevent the floor from moving. Metal fasteners in the floor structure are rarely used to avoid damaging cylinders in accidental contact.
⚠️ Warning: When installing cans, make sure they don’t RUB against the boat’s valves or seams, as constant vibration and friction can lead to scuffling and depressurization.
It is important (regularly check) the condition of the can fasteners, as plastic can get tired and crack over time, especially at low temperatures.
Installation of anchorages and bolts
Safe anchorage requires a reliable anchorage point that will withstand the thrust of the boat in the wind and current. squirt-bolt The crum-bolt is a metal ring on a threaded rod that is screwed into a special sleeve that is pasted into a cylinder.
The sleeve must be placed strictly perpendicular to the surface so that the load is evenly distributed, and the sleeve can cause the sleeve to tear out some of the fabric or deform the seat when it is pushed hard.
Large boats often use double dips or reinforced structures with a wide support area, and the anchor duck, in turn, allows you to quickly fix the anchor shaft and just as quickly poison it, which is convenient when catching in drift.
- ⚓ Choose the rim bolts with movable-ring for the convenience of fastening the carbines.
- 🌊 Install an anchor shroud in the bow of the boat for proper positioning on the water.
- 🔧 Use a sealant for threading to prevent water from entering the sleeve.
Remember that the anchor end should only be attached to the armatured armature, and the use of the handles or other elements for this purpose can cause them to break away and lose anchor.
Nuances of the installation of a bolt on the inflatable side
The process requires heating the sleeve to better adhesion the adhesive. Never screw the fry bolt into a newly glued sleeve — let the glue fully polymerize within 24 to 48 hours. A sharp load can disrupt the tightness of the joint before it starts operation.
Table of compatibility of fasteners and elements of the boat
To organize the information and help you choose the right tools for different tasks, we have compiled a summary table that will help you avoid errors in the selection of diameter and type of thread.
| Element of the boat | Recommended type of fastener | Materials | Features of installation |
|---|---|---|---|
| transom board | M6-M8 bolts with washers | Nerzh. steel AISI 316 | Requires the installation of reinforcing plates |
| Can supports (pyataki) | Press puck screws | Galvanizing or stainless steel | Only in the center of the pre-glued five. |
| Anchor rum | Roof bolt with sleeve | Brass or stainless steel | Complete polymerization of glue is required |
| The rod-holders | Hidden-head screws | Plastic or aluminum | Minimum hat projection inside the boat |
| Hanging bags | Buttons or carbines | Plastic/Metal | Fixing to Velcro straps or Slings |
As you can see from the table, there is no one-size-fits-all solution. Each node requires a customized approach and a specific solution. toolkitUsing the wrong fastener can negate all tuning efforts.
Self-installation tools and technology
To make a good fitting, you'll need a minimum set of tools. screw-up It's a torque-adjusted drill, so you don't overstretch the thread and damage the PVC, and you also need a drill with metal drills, a set of screwdrivers, scissors and a degreaser.
The installation process starts with marking. Measure distances carefully, use patterns or rulers for symmetry. A couple of millimeters error can cause the part to get crooked or interfere with the operation of the boat.
☑️ Checklist before drilling holes
When drilling holes in soft linings or transverses, it is recommended to use sharp drills and low rpms, so as not to melt the edges of the hole and damage the fabric. After drilling the edge of the hole, it is desirable to treat with a sealant or glue to prevent material from stratification.
⚠️ Warning: Before drilling any holes in the area of cylinders, be sure to make sure that there is no excess pressure inside, and place a wooden bar so as not to damage the opposite side when passing the drill.
The final step is to check all the connections under load, try to loosen the installed elements, make sure there are no backlashes, and then the boat can be launched.
The main principle of installation is “measure seven times, cut once”: careful marking and use of the right materials is more important than the speed of work.
Frequently Asked Questions (FAQ)
Can you use conventional construction screws for a PVC boat?
The use of conventional self-tapping screws is highly undesirable, often made of soft steel with a weak zinc coating that quickly wears off. In aquatic environments, such fasteners will rust in one season, spoil the appearance of the boat and may lose strength. sea-holder Stainless steel.
How to prevent the fastener from vibration of the motor?
To prevent spontaneous unscrewing, use lock nuts (with a plastic ring), growers (spring washers) or special carving fixers (anaerobic sealants). Regularly checking the puff before each release is also mandatory.
How to replace a broken pen to fasten the can?
If the pentacle is broken or unstuck, you can't just screw it back up again. You need to cut a new piece of PVC fabric (you can use a remix), clean and degrease the surface of the balloon thoroughly, apply glue and glue a new site. You can only operate the boat after a complete drying of the glue (24-48 hours).
What diameter of the drill to choose under a screw diameter of 4 mm?
For most screws on wood and metal, pre-drilling is not required if the material allows. However, for a dense PVC or trench board, it is recommended to use a 2.5-3 mm diameter drill to create a guide hole to avoid splitting or shifting the fastener.
