Modern water transport is undergoing significant changes, shifting the focus from traditional metal housings to lighter and more versatile designs. RIB-PND boats The Rigid Inflatable Boat is gaining popularity among anglers and waterwalkers, not just an inflatable boat, but a complex hybrid that combines the advantages of a rigid hull and the maneuverability of inflatable tubes.
Going out on such a vessel is radically different from using the classic Kazanka or cruzeika, there is no risk of corrosion, and blows on the pier or shore are extinguished by inflated cylinders, which keeps the hull intact. However, in order to operate only bring joy, you need to clearly understand the design features and limitations of the material from which the bottom is made.
Choosing a RIB is often a compromise between wanting a reliable vessel and not being able to store it permanently on a trailer or in water. Low pressure polyethyleneThe arches used to make the bottoms allow you to create complex contours that provide excellent germination on the wave. In this article, we will discuss in detail all aspects of owning such a boat.
Design features and advantages of RIBs
The basis of any boat type RIB is a hard bottom, which in our case is made of HDPE. This material has a unique chemical resistance and high impact resistance, which makes it ideal for operation in rocky shores and shallow water. He is not afraid of moisture at all. It does not require regular drying and painting after each season.
inflatable tubes surrounding the hard bottom have a dual function: they provide buoyancy and act as effective shock absorbers. When faced with an obstacle or hard-landed on a wave, it is the air inside the cylinders that takes the brunt of the blow, allowing higher speeds without risking damage to the structure or injuring passengers.
The important thing is that it's modular. You can choose a model with a design. keel (BDND) for maximum compactness assembled or with hard-keeled The hard keel, as an extension of the bottom, creates a deep keeled line, which is critical when you go out into open water.
⚠️ Attention: Despite the high strength of the HDPE, avoid prolonged contact of sharp objects with the bottom under load. Point pressure can lead to deformation, which is difficult to correct.
The design of the transom also deserves special attention. In high-quality RIBs, the transom is integrated into the bottom body and reinforced with additional elements, which allows you to install powerful motors without the risk of tearing off. Tran-Ear or a fully inscribed transom, which reduces water resistance and increases the efficiency of planing.
Comparison of materials: HDPE vs. plywood and aluminum
When choosing a boat, the owner always faces the question of the hull material: aluminum is durable, but cold, noisy and susceptible to electrochemical corrosion when improperly operated; plywood is cheap, but requires constant maintenance, varnishing and is afraid of stratification. PHN boats They occupy a niche of the “golden mean”, offering durability of plastic and comfort of use.
The main advantage of PHD over plywood is water-inertiaYou never have to worry that after winter storage, the plywood will swell or become covered in fungus, and the plastic does not absorb the smell of fish, gasoline or sludge, which makes it hygienic and easy to care for, just rinse the boat with hose water after use.
Compared to aluminum, HDPE benefits in tactile sensations and thermal insulation. The metal bottom in the sun gets hot, and in cold water cools instantly, creating discomfort. Plastic keeps the ambient temperature more smoothly. In addition, the HDPE has a "shape memory" effect and after deformation tends to return to its original state.
But there are some disadvantages to note: HDPE is heavier than plywood of comparable thickness, which can be critical for single boats that are planned to be carried alone. slip-coating (mats) on the floor is a prerequisite for safety.
Secrets of Durability of HDPT
With proper removal of the boats from the HDPE last more than 20 years. Ultraviolet is the main enemy, but modern stabilizers in the composition of the material effectively block its destructive effects.
specifications and dimensions of popular models
The market offers a wide range of sizes, from compact single-seaters to full-fledged boats. For fishing in small bodies of water, models with a length of 2.8-3.2 meters are optimal. They are easily controlled by low-power engines and have minimal weight.
The important parameter is load capacity and passenger capacity, and don't confuse these concepts: the load capacity includes the weight of people, motor, fuel and equipment. Real payload Often it is less than stated if you plan active planing with full load.
| Model boat | Length (m) | Width (m) | Body weight (kg) | Recommended motor (hp) |
|---|---|---|---|---|
| RIB-280 Compact | 2.80 | 1.40 | 45 | 5-9.9 |
| RIB-320 Fisherman | 3.20 | 1.55 | 58 | 9.9-15 |
| RIB-360 Profi | 3.60 | 1.75 | 72 | 15-25 |
| RIB-400 Tundra | 4.00 | 1.90 | 95 | 30-40 |
Boat width has a direct impact on stability. Models less than 1.40 meters wide can be dangerous when a fisherman moves from side to side. 1.50–1.70 metersThis ensures sufficient internal volume and stability on the wave.
The optimal length of a RIB boat for two adults with a motor and equipment is at least 3.2 meters. Smaller dimensions will be overloaded, which will lead to loss of driving performance.
Choice of motor and installation of attachments
The RIB engine is the balance between power and weight. The HDPE bottom has a certain weight, so a too weak engine will not bring the boat to plane with full load. two-stroke 9.9 hp with the possibility of forcing.
Installing the motor requires safety, and the boat's center of gravity shifts to the transom, so the placement of batteries and anchors must be thought out in advance, often in order to compensate for the weight of the motor, the battery box is installed in the bow or under the front seat.
- 🚤 Be sure to use the safety cable for the motor, run through the rim bolts on the transom.
- ⚓ To install the sonar, use a swivel bracket to be able to quickly remove the sensor.
- 🔋 Fix the fuel tank so that it does not move along the cockpit when the boat rolls.
Navigation and control also play a role, and RIBs often have a knob in their noses that serves as seats, and this allows you to unload the center of the cockpit. console-control With windshield, the inflatable boat turns into a full-fledged mini-boat that protects against splashes and wind.
When choosing a propeller, pay attention to step. Heavy RIB boats with HDPE bottom often require a reduced pitch screw or petal propeller so that the engine can spin to operating speeds and reach maximum power mode.
Operation, maintenance and storage of the boat
The hull should be rinsed with fresh water after every fishing trip, especially in salt water or overgrown water, to prevent the deposition of salts and organics, which can eventually get into the plastic structure or damage the valves.
Winter storage requires no special conditions, and HPD can withstand temperatures of up to -50°C, so the boat can be stored in an unheated garage or shed. discharge Or leave them slightly inflated to avoid warping from temperature changes, and protect them from direct sunlight if stored in summer.
☑️ Seasonal service
Particular attention should be paid to inflatable elements: the PVC fabric from which they are made is afraid of open fire and sparks. When installing gas equipment or a fire on the shore, keep a distance. Puncture repairs are carried out with standard remakes using PVC glue.
⚠️ Attention: Do not leave a fully pumped boat in direct sunlight on a hot day. The air inside the cylinders expands and the pressure may exceed the permissible limits, which will cause the seams to rupture.
For transportation in assembled form (with inflated cylinders), it is recommended to use a special trailer or soft cover-skating. HDPE is resistant to scratches, but sand and fine dust when rubbed can leave matte marks on the glossy surface of the plastic, which is only cosmetic in nature.
Safety on the water and advice of experienced boaters
Safety on the water depends not only on the technical condition of the boat, but also on the training of the crew. RIB boats are highly stable, but this does not make them unsinkable if you violate the rules of operation. The presence of life jackets is a requirement, regardless of the depth of the reservoir and the ability to swim.
When moving on planing, it is important to distribute the weight correctly. Passengers should sit in their seats without moving sharply. The center of gravity should be in the diametric plane. tipping Or the boat's cripple.
- 🌊 Always carry an anchor with a reserve of line at least triple depth in the parking lot.
- 🔦 Navigation lights are mandatory when driving at night or in poor visibility.
- 📞 A cell phone in a sealed case or waterproof radio station should be available at any time.
Experienced water-engines advise always to have a remix and a pump, running on the battery of the outboard motor or car pump. Situations with a puncture of a balloon are rare, but it is the presence of a tool for rapid repairs that allows you to continue driving or safely reach the shore.
Take a bright flare or smoke bomb on board, and in the event of an emergency on a large body of water, it is extremely difficult to spot a small boat from the shore or from a passing vessel without visual signals.
What pressure should be in RIB tubes?
The optimum operating pressure in cylinders is usually 0.2-0.25 atmosphere (200-250 mbar), the exact value is indicated in the product passport. Pumping cylinders is dangerous to rupture seams in the sun, failure to pump leads to loss of rigidity of the structure and reduced driving performance.
Can I walk on the RIB against the current?
Yes, RIB boats with keeled HDPE bottoms are excellent at steering and confidently against the current even with moderate wave, but for rivers with strong currents, it is recommended to use motors of at least 15 hp for boats from 3.6 meters in length.
Do I need to register a RIB boat in GIMS?
Registration is mandatory if the weight of the outfit vessel (hull + engine + equipment) exceeds 200 kg, or if the engine power exceeds 8 kW (about 10.8 hp). For small boats with engines up to 5 hp, registration is usually not required, but the rules may change, so it is worth clarifying the current legislation.
How to wash the bottom of the HDPH from oil and oil?
PDD is chemically inert, so household detergents, diesel fuel or special plastic cleaners can be used to clean the material. Avoid using aggressive solvents such as acetone or 646, which can damage the material's structure or make it matte.
