The organization of space in a small vessel is not just a matter of comfort, but often a matter of safety on the water, and the chaotic scattered gear, anchor ropes and tools not only interfere with the operation of the vessel, but also create the risk of catching or losing valuables overboard. boat-boat It is one of the first accessories to be purchased or manufactured by experienced water-engines after the purchase of the vessel itself.
This tuning element has a dual function: it serves as a safe seat for a passenger or rower and provides a sealed storage for equipment. Unlike simple bags or bags, a quality box protects the contents from splashes, rain and even short-term immersion. chest It allows you to turn an open cockpit part into an organized workplace.
The choice of a particular model depends on the type of boat, whether it is lightweight. PVC inflatable boat or heavier aluminum KazankaIt is important to consider the dimensions of the cockpit so as not to disturb the balance of the vessel and not to hinder the movement of the rower. In this article, we will discuss in detail the selection criteria, compare materials and consider the step-by-step process of installation and manufacture.
Criteria for choosing a runduk for different types of boats
When selecting equipment for storage in the boat, the overall dimensions are of paramount importance. transom-wheelFor narrow inflatable boats, models with rounded or beveled sidewalls that replicate the shape of cylinders are optimal, while flat-bottomed and metal boats are better suited to flat-bottomed rectangular structures that provide maximum stability.
The material of the case also dictates its requirements. ABS plastic or polypropyleneThey are lightweight and waterproof, but they can be less resistant to impacts at temperatures below zero. Aluminum variants are stronger and more durable, but they are susceptible to corrosion when in contact with salt water if they do not have a quality powder coating.
Pay attention to the lid mounting system. The hinges must be made of stainless steel brand. 316 Cheap loops oxidize quickly and can break at the wrong time, leaving your cargo unprotected, and the ability to install a lock or latch to prevent spontaneous opening on the wave is also important.
⚠️ Note: When choosing a runduk for an inflatable boat, make sure that the bottom of the drawer does not have sharp corners or roughness that can damage the boat. PVC fabric floor when the boat is moving or passengers board.
Materials of manufacture: plastic, metal and wood
The market offers three main areas of materials, each with its own advantages and disadvantages: Plastic is the leader in popularity due to its availability and ease of care. rotary or ABS They don't rust, they don't rot, they're easy to wash, and they're perfect for storing things that don't require absolute tightness, because many plastic models have only sealing gum, but they're not completely waterproof when they're completely submerged.
Metal hazelnuts, most often made of aluminum, are chosen by boat owners and heavy boat owners. mechanical strengthThis box can withstand the weight of several adults, can be used as a support for the installation of additional equipment and does not deform under the influence of sunlight. However, the metal has a high thermal conductivity: in the sun, the lid can be very hot, and in the cold - cool, which is worth considering when using.
Wooden runduks made of moisture-resistant plywood or an array of larch are classified as DIY (do it yourself) or premium tuning. The wood is aesthetically pleasing, it doesn't slip. But without careful treatment with epoxy resins, varnish and antiseptics, it quickly loses its appearance and strength in an aggressive aqueous environment. The weight of a wooden box is usually higher than that of a plastic counterpart.
- 🛡️ Plastic: light, does not rust, cheap, but can crack in the cold.
- ⚙️ Metal: heavy-duty, withstands heavy loads, but heavier and more expensive.
- 🌲 Tree: It is beautiful, you can make any shape, but requires constant care.
Secrets of the Durability of Wooden Runduks
For the manufacture of wooden harunduk, use only moisture-resistant plywood of the FSF brand or aviation plywood BS. It is mandatory to impregnate all ends and planes with epoxy soil before finishing the painting. Even one microscopic scratch to a living tree can start the process of rotting.
Tightness and protection of the contents from water
The issue of tightness is critical for many water-engines, and it is important to clearly distinguish between waterproof and waterproof. Most standard hazelnuts protect against splashes, rain and swelling, but do not guarantee dryness when fully submerged. sealing-profile (usually of EPDM rubber or silicone) that is pressed by a perimeter lid.
The design of the lid also plays a role. O-ring (a round rubber ring in the groove) provides better insulation than simple flat pads. Some manufacturers equip their products with drain valves that allow water to be removed without opening the lid, which is convenient for storing tackles that do not need to be completely dry, but do not need to swim in a puddle.
To store electronics, documents or changeable clothing, it is better to use additional sealants or plastic containers inside the kunduk itself. chest It can pass moisture through loops or keyholes in a severe storm or boat roll, and double protection is the standard for water safety.
| Type of protection | Description | Recommended application |
|---|---|---|
| Basic | Tight fit of the rubber-free cover | Protection from sun, dust, large splashes |
| Waterproof | Perimeter rubber sealer | Rain, wave, storage of tools and clothing |
| Tightened | O-ring + latch lock system | Electronics, documents, valuables |
| Example | Simple plastic crates | Anchor rope, rag. |
| Example | Runduks with EPDM profile | Spinnings, sonar, clothes |
| Example | Specialized marine boxes | Navigators, walkie-talkie, money. |
Installation of a handduk in a boat: step-by-step instructions
Proper installation of the harunduk ensures not only its safety, but also the safety of passengers. A box that floats at speed or wave can become a dangerous projectile. Installation depends on the type of boat: inflatable boats often use belts or special areas with valves, while metal and wooden boats use a bolt joint or adhesive sealant.
To install in a PVC boat, you first need to degrease the surface of the balloon or floor at the mounting site. If you use a platform, it is glued to a special glue for PVC. Then the rundock is fixed on the platform. It is important not to drag the fasteners to avoid damaging the material of the boat. Metal boats drill holes under the bolts, the mounting places are necessarily treated with anticort.
☑️ Checklist before installation
An alternative to a rigid fastening is the use of sling This method allows you to quickly remove the box for cleaning or repositioning, but requires regular tension checks. Weakened belts can cause the center of gravity of the boat to shift, which is especially dangerous when maneuvering.
⚠️ Warning: When drilling holes in the metal body of the boat, be sure to use a cobalt-coated metal drill and immediately treat the edges of the hole and bolt caps
zinc-containingTo avoid electrochemical corrosion.
Manufacture of a hand-held hand: drawings and tips
Creating a handmade handmade kunduk is a great way to get a product of the perfect size for your particular boat and save the budget. The most affordable material for a home workshop is moisture-resistant plywood thickness. 10-12 mmThe design is a box with a lid, reinforced with ribs, and the best way to connect the parts is to use glue. Titebond III or epoxy resin in combination with stainless steel screws.
The key to self-manufacturing is waterproofing, and once the box is assembled, all surfaces, including the inner corners and ends, need to be coated with a layer of epoxy resin with microspheres or just a thick layer of epoxy soil, which creates an impermeable barrier. carpet (carpet) or paint rubber paint, which will also improve grip and reduce noise.
To create a high-quality seal in a homemade hazelnut, use a D-profile window rubber seal glued around the perimeter of the lid to moisture-resistant glue. This will ensure tightness as well as factory models.
The homemade hinges are better to take ready-made, automotive or furniture, but always made of stainless steel. If the budget is limited, you can use a strong rubber band as a hinge, passing it through holes in the body and lid, although this is less reliable, the main thing is to ensure that you can close tightly.
- 📏 Accurate measurements: take the dimensions from the boat, taking into account the curvature of the sides.
- 🔨 Furniture: you can not save on hinges and locks, they carry the main load.
- 🎨 Finish: Use non-slip coatings for foot safety.
Caring for a runduk and extending the service life
Even the best quality hazelnut requires regular maintenance, especially if it is operated in harsh conditions. Salt water, ultraviolet light and temperature changes aggressively affect materials. Plastic can fade and become brittle over time, metal can become covered with oxides, and wood swell. Regular washing with fresh water after each foray to the sea or fishing will significantly prolong the life of the accessory.
Special attention should be paid to moving parts: hinges and locks. They must be periodically lubricated with silicone lubrication or WD-40 (with subsequent cleaning of dirt) to prevent jamming. Rubber seals are useful to treat special conditioners for rubber so that they do not dry out and crack.
Regular drying of the internal space of the runduk prevents the appearance of mold and an unpleasant smell that can spread to stored things.
If you notice damage to the coating, chipped paint or scratches on the metal/wood, do not delay repairs. A small defect will quickly turn into a big problem under constant exposure to water. In the off-season, it is better to store the rundock in disassembled form or with an open lid in a dry room to avoid condensation inside.
FAQ: Frequently asked questions
Can you use a conventional construction box instead of a specialized sea hazel?
You can use it, but with caution. Building boxes are often not protected from UV and can become brittle in the sun. Also, their locks and hinges are not usually designed for salty environments and will quickly rust. For short trips to fresh water this is acceptable, but for regular fishermen it is better to buy a specialized one. sea-box.
What is the optimal volume of a harunduk for a boat 3.2 - 3.6 meters long?
For boats of this size, the optimal volume is 40 to 60 liters. A larger volume can take up too much space in the cockpit, interfering with the placement of passengers or the engine. A smaller volume (20-30 liters) will only be useful for small things, but will not solve the problem of storing large things like anchors or life jackets.
How to prevent things from fogging inside a runduk?
Condensate is produced by temperature changes, and to minimize this effect, use airtight zip-lock bags inside the kunduk, and you can also put a silica gel bag inside the crate, which will collect excess moisture from the air inside the crate.
Will a plastic hazelnut bear the weight of an adult?
Specialized boat handles are typically designed to carry static loads of up to 100-150 kg, which allows them to be used as a seat. However, cheap household containers can not withstand dynamic load (sharp seating) and crack. Always check the manufacturer's specification before you sit on the box.
What is better to fasten the kunduk in an inflatable boat, so as not to damage the cylinders?
The best way is to use soft, length-adjusted slings that cover cylinders or pass through special rings on the boat, and you can only attach rigid bolts to a transom board or a special high-pressure inflatable floor, but not to the balloon itself.
