Every experienced boater knows that free space on an inflatable boat is valued for its weight in gold. A nose-dump on a PVC boat It's not just a box, it's a critical ergonomic element that allows you to unload the cockpit from excess gear, and without well-organized storage, fishing gear, remixes and personal items become a chaotic pile that prevents you from moving through the cylinders.
Well-chosen forepic Or the nosebox can do a number of things, from protecting things from splashes to improving the performance of the vessel by shifting the center of gravity, and in this article, we'll look at what materials are best suited to harsh operating conditions, how to avoid typical installation errors, and why homemade structures often outperform factory counterparts.
Purpose and functionality of the nose box
The main function of the nose harunduk is to systematize the cargo. Waterproof box It allows dry clothing, electronics and food to be stored even in heavy waves or rain, and it also helps to offset the weight of the engine and passengers on the stern, which is especially true for boats less than 3.5 meters long.
In addition, the rigid design of the runduk can play a role. extra-stiffness It's a very inflated cylinder, preventing it from deforming when driving at high speeds. Some models are equipped with soft linings, making the lid a comfortable seat for a spinner or passenger. It's important that the interior space is as efficient as possible, without unnecessary partitions that occupy usable volume.
Do not forget about safety: securely fixed nose-nose It prevents heavy objects (e.g., anchors or batteries) from rolling over the cockpit during sharp maneuvers, reduces the risk of cylinder damage by sharp angles of gear, and makes fishing or cruising much more comfortable and safer.
Materials of manufacture: plastic, plywood or aluminum
The choice of material is the first and most important step, and most often, moisture-resistant plywood, reinforced plastic or aluminum alloy are used to make hazelnuts. FSF phanera It is popular due to its strength and the possibility of self-treatment, but it requires high-quality varnishing or pasting, since with prolonged contact with water it can still dissipate.
Plastic models made from ABS plastic They are lightweight and require no additional care, but they are usually higher cost and the color range is limited to factory solutions. Aluminum boxes (often made of AMG alloy) are high strength and light weight, but when hit on board can make a loud ringing and require isolation of the contact points with PVC.
⚠️ WARNING: When using metal fasteners or aluminum hull, be sure to isolate contact points with the boat fabric to avoid electrochemical corrosion or mechanical rubbing of the cylinder.
For self-made workers, a combination of materials is often the best option: a plywood frame, a glass-covered fabric, or a carpets-plated carpette. non-standardIt perfectly repeats the curves of cylinders of a particular model of the boat, which is impossible to do with ready-made plastic analogues.
Use epoxy glue with the addition of aeroforce to glue parts - it creates a water-resistant seam, not afraid of vibration and moisture.
Selection criteria: size, shape and tightness
When selecting or designing a kunduk, geometry is a key parameter. The nose of PVC boats has a specific cone-shaped shape, so a standard rectangular box may simply not stand in place or, worse, start pressing the cylinders, creating a dangerous stress of the material. Optimal shape It should repeat the contours of the nasal triangle, leaving small gaps to compensate for the pressure changes in the cylinders in the sun.
Tightness is the second most important criterion. Even if the harunduk is not intended to be used as a caisson, spray protection is mandatory. rubber-strap It is important to check the reliability of the latch locks: they must fix the lid even when shaking strongly, but they can be easily opened with one hand.
The weight of the structure also plays a role. Too heavy nose hazelnut can cause the bow of the boat to "buried" in the wave when for an outboard motor, especially at low power. Lightweight composite materials or thin but durable plywood (9-12 mm) is preferable to massive metal structures.
Step-by-step instructions for DIY installation
Installing a nose knob requires carefulness and adherence to technology so as not to damage the inflatable tubes, and the installation process can be divided into several stages, each of which affects the final result and safety of operation.
☑️ Checklist before installation
Measure the distance between the insides of the cylinders at the widest part of the intended installation and at the narrowest (at the transom or duck of the nose). Gap. The length of the air between the rod and the balloon should be at least 1-2 cm on all sides, which will prevent friction when inflating the boat and changing the air temperature.
If the bottom of the boat (floorboard) is not rigidly fixed in the nose, the kunduk may require additional attachment points. In some cases, slings are thrown through cylinders, but a more reliable option is to attach to the mount. D-rings, glued into cylinders, or to floorboards through special holes (if the design of the boat allows it).
⚠️ Warning: Never drill cylinders to hold a harunduk! Use only standard fastening elements or methods that do not violate the integrity of the PVC fabric.
The final step is to lock and check, and you can set the box, spread the load evenly, and see if it deforms the balloons when it's inflated, and the lid should open freely, without facing the sides of the boat or the awning.
Comparative table of runduk models
To simplify the choice, consider the comparative specifications of popular types of nose boxes available on the market or suitable for self-manufacture.
| Type of material | Weight (average) | Water resistance | Difficulty of installation |
|---|---|---|---|
| Plywood FFS (glazed) | Medium (3-5 kg) | High (when processed) | Medium |
| Plastic (ABS/Polyethylene) | Low (2-3 kg) | Absolute. | Low. |
| Aluminum (AMG) | Low (2-4 kg) | Absolute. | High. |
| Fiberglass | Tall (5-7 kg) | Absolute. | High. |
As you can see from the table, plastic models win in simplicity and water resistance, but lose in the possibility of customization. Fiberglass It gives complete freedom of form, but requires serious skills and equipment to make plywood, which remains the "golden mean" for the home craftsman.
The secret of the durability of plywood runduk
Cover the plywood with two layers of epoxy resin with fabric, and then apply the finishing lacquer for the yachts, which will create armor that will outlast the boat itself.
Refining and tuning of the nose part
A finished rundock is just a base, it can be upgraded to maximize comfort, and a popular solution is to put a soft seat on the lid, and it uses a high-density foam and a wear-resistant fabric (oxford or vinyl) stretched over a wooden base, which makes the box a complete one. fishing-chair.
Inside the runduk, it's useful to organize a system of organizers. Plastic containers, fixed with Velcro or simply inserted, will help keep the little things in order. Also, many owners integrate rod mounts or sonar holders into the runduk lid, which frees up the hands during the transitions.
It is not superfluous to equip the box with reflective elements or LED lighting, powered by a small battery, which will allow you to quickly find things in the dark without using a flashlight that you need to constantly hold in your mouth or hand. LED tape consumes minimal energy and significantly increases the ease of operation.
The main goal of tuning is to turn the runduk from a simple storage facility into a multifunctional boat control center.
Frequently Asked Questions (FAQ)
Can a nose fungus be used as a caisson to store things underwater?
Only if it's specifically designed for this and labeled, ordinary boxes, even plastic ones, are not designed to keep the water column at constant pressure and can burst or lose their tightness at depth. Use specialised sealants or caissons to store things in water.
How to prevent things from fogging inside a runduk?
The temperature difference leads to condensation. Use silica gel bags (moisture absorber) by placing them inside the drawer. Also helps periodic ventilation of the runduk after fishing and storing the boat in the assembled form.
Does the runduk affect the speed of the boat?
The cockpit itself doesn't affect hydrodynamics. However, if it's too high and wide, it can sail in the wind or interfere with the work of the oars. The main thing is proper weight distribution: the load in the nose balances the boat, improving glides.
What is the best way to fix the horn so that it does not go?
The ideal option is to use standard liner struts or slings that run through D-rings on cylinders. Hard attachment to floorboards is only possible if the design of the boat allows it. Simple friction on PVC fabric is unacceptable.
