Operating an inflatable vessel requires a special approach to the placement of equipment, especially when it comes to the bow, and this is where water accumulates most often, and this is where the spray gets when moving against the wave. Nose rod for PVC NDND boat It becomes not just a convenient accessory, but a vital storage system that allows you to keep things, tools and food dry during long hikes.
Unlike the classic models with plywood floorboard, the design NDMA The rules of the book are: you can't drill through the cylinders without thinking, and the weight of the equipment should be minimal, and a well-chosen cockpit box or caisson solves the problem of wet floors and randomly scattered things, turning the boat into a full-fledged tourist tool.
The choice between a finished solution and self-manufacturing often depends on the model of the vessel and the owner’s budget. Modern materials allow you to create lightweight but durable structures that do not disturb the balance of the boat. In this article, we will discuss in detail all aspects of the selection, installation and operation of this important element of equipment.
⚠️ Attention: Installing any rigid equipment in the bow of the boat shifts the center of gravity. Excessive loading of the nose can lead to the buoyancy of the vessel in the wave and reduced driving performance.
Design features of rundukes for NDND
The main feature of boats with low pressure inflatable floor is the absence of a hard floor, which excludes the possibility of installing standard boxes with a flat bottom. nose-dump for such models should either rely on cylinders, or have a special suspension system that does not damage the PVC fabric. Most often, trapezoidal structures are used that repeat the bends of cylinders in the nose.
The material of the casing plays a critical role: aluminum alloys, such as AMG5PThey are ideal for marine conditions, as they do not rust and have high strength. ABSPlastic or polypropylene is lighter, but can crack when hit by a stone in extreme frost. Wooden boxes covered with sea lacquer look aesthetically pleasing, but require constant care and are prone to swelling.
An important element is the sealing system, and even if the box itself is waterproof, moisture can penetrate through loops or locks. sealer The perimeter of the lid is a requirement to keep things dry, and some models are equipped with drain valves that allow you to remove condensation without opening the lid.
- 📦 Aluminum caissons - maximum strength and durability, but higher price.
- 🛡️ Plastic boxes - lightness and accessibility, suitable for calm water.
- 🪵 Wooden structures - require impregnation, heavier than analogues, but repairable.
When choosing a runduk, pay attention to the radius of rounding corners: sharp edges can damage the fabric of the boat when actively pitching or mooring.
Materials of manufacture and their impact on the operation
The choice of material directly affects the weight of the entire structure and, as a result, the carrying capacity of the boat. aluminum The sheet is 2-3 mm thick and can withstand severe loads if you accidentally step on or lean on a box when rowing, but metal conducts is warm, so in the heat things inside can heat up, and in the cold - cool down.
Modern composite materials and impact-resistant plastics are gaining popularity, they are inert to chemistry (gasoline, oil, fishing fat) and do not require painting. Polypropylene It's easy to weld, which allows you to create sealed seams without the use of bolts and rivets, which can become points of corrosion or leakage, and the disadvantage of plastic is its fragility at extremely low temperatures.
The tree, despite being archaic, has its fans. -Plywood brand FSF It's a hard, beautiful, stained tree, but it absorbs odors and moisture, which can cause mold inside the boat, and to use it in a nose hazel, the wood parts have to be perfectly processed.
| Materials | Weight (kg) | Strength | Tightness | Price. |
|---|---|---|---|---|
| Aluminium (AMg5P) | Medium. | High. | Tall (with seal) | High. |
| Plastic (ABS/PP) | Low. | Medium | High. | Medium |
| FSF phanera | Highly | Medium | Low. | Low. |
| Fiberglass | Medium. | High. | High. | High. |
Forward anchorage systems
Installation nose-duck The main task is to fix the box so that it does not move during the course, but also does not rub the fabric of the cylinders. The most common method is the use of regular liner rings and slings. The box is equipped with eyelets through which a strong sling is passed, covering cylinders or passing through transom rings.
There are models with Velcro straps or special pockets that are placed on cylinders, which are only suitable for lightweight plastic boxes. Heavy aluminum structures require more rigid fixation. It is important to avoid contact of metal attachments with PVC fabric without protective linings from the PVC. kevlar Or a tight ribbon.
Some anglers practice placing a knuckle on a removable platform, which in turn attaches to stringers (if the boat design permits) or to an inflated bottom, which allows you to quickly dismantle the boat dryer box. The main rule is to eliminate the backlash. The moving box quickly turns into a file that rubs the bottom.
⚠️ Warning: Never use sharp metal hooks or carbines without insulation in contact with cylinders. Friction on water can wipe even reinforced cloth in one season.
☑️ Checking the runduk anchorage
Tightness and protection of contents
Water in a boat is an axiom, so tightness The harunduka comes first. Even if the boat doesn't draw water on the sides, condensation and splashes do their job. A quality harunduka must withstand full immersion for a short time (for example, in a flip), using rubber seals around the perimeter of the lid and reliable latches.
The inside of the drawer often condensates due to temperature changes (cold water below, warm sun on top), to keep things from damping, it is recommended to use internal sealants or smaller plastic containers, and silica gel bags are also effective, which need to be changed or dried regularly.
Locks and hinges must be made of stainless steel brand 316 Or brass. Conventional steel will rust after the first fishing, leaving rusty leaks on the fabric of the boat and clothes, and the hinges are better chosen with the option of replacing the pin, since this is the most loaded element.
How to check the leakage of the house?
Put a dry napkin or paper inside, close the knuckle tightly and drop it into a bath of water (or pour plenty of hose) for 10-15 minutes. If the paper is dry, the box is ready to operate.
Ergonomics and additional equipment
Modern. nose-dump It's a multifunctional knot, and it often has a soft seat on it, which is especially true for NDNDM boats, where rigid cans can be absent or uncomfortable, and the seat should be removable so that it doesn't wet the clothes with wet plastic or metal.
Inside, it's advisable to organize space with removable partitions or nets, which will prevent tools and fuel cans from rolling over while driving, and some models have built-in rod or glass holders, which frees the angler's hands.
Appearance also matters. Powder paint or anodizing not only protects the metal, but also allows you to match the color of the boat. Light colors are less heated in the sun, dark colors are less branded, but warmer. The choice depends on the owner's priorities.
- 🪑 Removable soft seat - comfort and dry clothes.
- 🎣 Fastenings for tackles - order in the cockpit.
- 💡 Place for installation of running light - safety on the water.
⚠️ Warning: When installing a soft seat, make sure that the fabric of the cover is made of water-repellent material with antifungal impregnation, otherwise it will become a source of unpleasant odor.
Self-made vs Buying finished
The decision to make a kunduk yourself or buy a ready-made one depends on the skills and availability of tools. AMG Alloys often have rolled edges and perfect geometry, which is difficult to replicate in a garage without a bending machine.
The homemade version allows you to take into account all the nuances of a particular boat. You can make a box exactly the size of the throat between the cylinders, making the most of the useful space. You will need sheet material, a rivet and a sealant. It is important to remember about weight: homemade products are often heavier than factory ones due to overconsumption of the material with a margin.
If you choose a self-manufacturing path, pay attention to the processing of edges. Any barb on aluminum or a sharp angle of plywood is a potential hole in the balloon. K-shaped profile Or the sleeving of the edges is mandatory.
Buying a finished harunduk saves time and guarantees the quality of the assembly, but self-manufacture allows you to create an accessory that is ideal for your boat at the price of materials.
Care and maintenance in the offseason
Proper storage extends the life of not only the boat, but also the equipment. After the season, the hazelnut must be thoroughly washed with fresh water, removing the residues of salt, silt and fish mucus. Metal parts should be treated with protective lubrication, even if it is stainless steel, to avoid oxidation in the areas of friction.
Rubber seals are recommended to wipe with silicone lubricant so that they do not dry out and crack during the winter. It is better to store the kunduk in an open form (the lid is removed or open), so that mold does not start inside and a musty smell does not appear.
Before assembling the boat in spring, make sure that the mounts and slings are inspected. The fabric elements may have weakened or worn out. Replacing the worn sling in a timely manner will prevent the loss of valuable cargo during the alloy.
Frequently Asked Questions (FAQ)
Can a nose rund be used as a rowing seat?
Yes, many models are specifically designed to accommodate seating load (up to 100-120 kg), but make sure that the box-to-boat mounting system also can withstand this weight and does not shift.
How tight is the runduk in a complete boat flip?
High-quality models with rubber seals and reliable locks hold water during short-term immersion, but they are not designed for prolonged exposure to water (like sealants), so valuable documents and electronics are better duplicated in individual sealers.
Will the installation of a runduk affect the speed of the boat?
Minimal. The runduk is in the bow, which is raised above the water when you're driving the motor, and the main effect is the shift in the center of gravity, and if the boat goes forward, the speed and handling will drop, so don't overload the box with excess weight.
How to deal with condensation inside a metal box?
Use moisture absorbers (silica gel), put things in plastic bags inside the drawer and try to leave the lid ajar during parking in dry weather for ventilation.
