Boats like this. rib The Rigid Inflatable Boat has long been popular among fishermen and water enthusiasts, but while classic models are usually associated with an aluminum or fiberglass body, a new solution has appeared in recent years. RIB from the MND This material, familiar to many from plastic barrels and pipes, has been remarkably effective in producing small vessels.

So what makes polyethylene RIB boats so attractive? rigidity s ease and maintainability Second, HDPE is resistant to corrosion, shock and temperature extremes — ideal for harsh Russian conditions, but it also has pitfalls, from limited speed to specific repairs, and in this article, we'll look at all the nuances, from design to real-world experience.

If you choose between a PVC boat, an aluminum boat, and an HDPE RBI, you'll find an objective comparison here. If you already own it, you'll learn how to extend the life of the boat and avoid common mistakes. Let's start with the main thing: what is HDPE and why is it used in shipbuilding.

What is PHD and how is it used in RIB boats?

LDPE (low pressure polyethylene) is thermoplasticIt's made at high pressure and temperature, and unlike the PVC that we all know, HDPE is chlorine-free, it doesn't emit toxins, it's completely recycled. In boatbuilding, it's used to make it. rigid RIB, while the sides remain inflatable (from PVC or hypalon).

Key properties of HDPE, important for boats:

  • 🛡️ Impact resistance: withstands collisions with stones, snags and ice without cracks.
  • ❄️ Frost resistance: does not lose its properties at -50°C (unlike fiberglass, which becomes brittle).
  • 🔄 Elasticity: when deformed, returns its original shape (for example, after a run aground).
  • 🧪 Chemical inertia: does not respond to gasoline, oil or salt water.

The process of building the casing is simple: the PHD sheets are heated and molded under pressure, and then welded together. seamlessBut there's a limitation to this method: it's hard to make HDPE housings that are complex (like deep V-bottoms), so most models have simplified geometry.

Pros and cons of RIB boats from the PND: an honest comparison

To see if a polyethylene boat is right for you, compare it to the alternatives.

Parameter RIB from the MND Aluminum rib PVC boat Fiberglass boat
Weight (3rd model) 45-60 kg 70-100 kg 25-35 kg 120-200 kg
Strength of shell High (shockproof) Very high (but corroding) Low (punctures) Medium (fragile on impact)
Repairability Difficult (requires welding) Medium (rivets, welding) Simple (glue, patches) Difficult (lamination)
Speed (with a 15 hp engine) Up to 40 km/h Up to 50 km/h Up to 30 km/h Up to 60 km/h
Price (3rd model) 180-250 thousand rubles. 250-400 thousand rubles. 80-150 thousand rubles. 350-600 thousand rubles.

An important caveat: HPD boats are not suitable for high-speed wave riding because of the flexibility of the material. At speeds above 45 km / h, the hull can "play", which leads to loss of handling. But they are ideal for quiet fishing, hunting or family walks along the river.

Advantages of RIB from PND:

  • 💰 Price.: cheaper than aluminum and fiberglass analogues by 20-30%.
  • 🛠️ Service: does not require painting, anti-corrosion treatment.
  • 🌡️ Heat resistanceIt does not crack in the cold and does not melt in the sun.
  • 🚫 Security: does not conduct electricity, does not spark during impacts.

Disadvantages:

  • ⚡ Motor restraint: Most models are allowed to install engines up to 20 hp
  • 🔧 Difficulty of repair: cracks in the body are eliminated only by welding the HDPE (not every service is taken).
  • 📉 Degradation in the sun: Without UV protection, polyethylene tarnishes and loses strength in 5-7 years.
💡

RIB boats from the PND are optimal for calm water (lakes, rivers, bays) and are not designed for sea waves or extreme drifting.

In the Russian market, polyethylene boats are offered by both domestic and foreign brands.

1. Bark RIB-MND (Russia)

Series Bark RIB-PE The model includes models with length from 2.8 to 4.2 m.

When choosing, pay attention to thickness of the HDPE8-12 mm: Models thinner than 6 mm risk deformation during intensive operation.

How to distinguish a quality HDPE from a fake?

There are boats on the market that have a secondary HDPE (recycled) body, which is fragile and cracks quickly, and you can check the quality on two things:

1. Colour: high-quality HDPE matte, without yellowness.

2. Smell.Cheap polyethylene smells like chemistry, original is neutral.

If the seller refuses to provide a certificate for raw materials, this is a reason to be wary.

How to choose a RIB boat from the HDPE: 7 key criteria

When buying, pay attention to the following parameters:

  1. Length and load capacityFor fishing together, 3 models (load capacity 300-400 kg) are enough for a family with children - from 3.6 m.
  2. Thickness of the MHPOptimally 8-12 mm Thin body (5-6 mm) bends under the weight of the engine.
  3. Bottom constructionThe flat bottom is suitable for calm water, the V-shaped (angle 10-15 °) for a small wave.
  4. Inflatable board materialPreferably. hypolatone (more long-lasting than PVC).
  5. CompletementThe basic version should be: pump, oars, repair kit, banks.
  6. CertificationCheck the availability. GIMS certificate and the boat's passports.
  7. GuaranteeThe minimum period is 2 years per case, 1 year for PVC elements.

Don't chase cheap models without a brand. "nonaim" It is often made from low-quality HDPE, which cracks after the first season.bark, frigate, Zodiac).

Check the thickness of the HDPE (minimum 8 mm)

Check the maximum power of the motor

Check the seams of inflatable sides (must be glued and stitched)

Ask for a GIMS certificate of conformity

Make sure there is a repair kit in the kit.

Operation and care: how to extend the life of a boat from the HDP

Low pressure polyethylene does not require complex maintenance, but there are nuances:

1. Storage:

  • 🏠 Keep it in winter dry-room at temperatures above 0 ° C (HDP becomes fragile in the cold).
  • ☀️ Avoid direct sun: UV rays destroy the polymer. Use a case or keep in the shade.

2. Purge.:

  • 🧽 Wash the case softbrush with soapy solution (without abrasives!).
  • 🚫 Do not use solvents (acetone, gasoline) - they corrode HDPE.

3. Repairs.:

  • 🔧 Small scratches, grind sandpaper. P120–P220.
  • 💥 Fix the cracks PDW (Silver iron + filler rod) Glue doesn't fit!

4. Transportation:

  • 🚗 Transport the boat on the roof of the car to soft-tie (Not linen ropes!)
  • 🛩️ When flying on an airplane, take as bulky luggage (Insure beforehand).
💡

To prevent the formation of microcracks, once a season treat the case with a special UV protective paste for HDPE (for example, PolyCare UV-ProtectThis will extend the service life by 30-40%.

⚠️ Attention.: Never keep a PHD boat inflated under direct sunlight. Air pressure inside the boards increases when heated, which can cause seams to rupture. Optimal pressure in the cylinders. 0.2-0.25 bar.

Tuning and improvements: what can be improved in RIB from PND

Basic models often require improvements to make them comfortable to use, and here are some popular improvements:

Body reinforcement:

  • 🛡️ Install. keel-proof from stainless steel or aluminum (prevents the abrasion of the bottom).
  • 🔩 Secure it. prairie (if the plastic is used by the staff).

Fishing equipment:

  • 🎣 Add in. fishing-rod (for example, Scotty).
  • 🔋 Install. sounder with a transom attachment.

3. Comfort:

  • 🪑 Replace the standard banks with adjustable seats (for example, Attwood).
  • ☂️ Attach it. tent to protect you from the sun.

4. Security.:

  • 🚨 Add in. escapade: pump, repair kit, signal mirror.
  • 🔦 Install. LED navigation lights (Swimming is required in the dark).

When tuning, avoid drilling the body unnecessarily - each hole weakens the structure. glue-base (for example, 3M VHBor rubber-barrel.

⚠️ Attention.: Do not install a RIB from HDPE motor more powerful than the manufacturer allows. The polyethylene housing is not designed for high loads: if you exceed power, the bottom can bend, and the transom can break off.

Reviews of owners: real experience of operation

To make an objective opinion, we analyzed the reviews from the forums (see below).FishHunting, BoatMaster) and social media groups, here are typical opinions:

Positive:

  • 👍 "I bought the Bark 320 two years ago, not a crack, although I often drag on rocks, the main thing is not to hit sharp objects." (Igor, Moscow)
  • 👍 "Lighter than aluminum 2 times, and the strength is not inferior. In winter, I keep in the garage without a case - no problem." (Alexey, St. Petersburg)
  • 👍 "For fishing on the lake, perfect. Quiet, doesn't scare fish like metal." (Dmitriy, Novosibirsk)

Negative:

  • 👎 "I bought a cheap Chinese model, and after a year, the bottom sagged. I had to strengthen the fiberglass." (Sergei, Yekaterinburg)
  • 👎 "At a wave above 0.5 m begins to walk - not comfortable. Better to take with a V-shaped bottom." (Anton, Krasnodar)
  • 👎 "I tried to weld the crack myself, it was crooked. I had to take it to the service." (Oleg, Kazan)

The general conclusion: 80% of owners are satisfied They're all made of HDPE boats, but only if they're operating properly, and the main complaints are about cheap models and spare parts.

FAQ: Frequent questions about RIB boats from MHP

Can I use a boat from the PHD in winter?

Yes, but with reservations, the HDPE can withstand frosts of up to -50°C, but at temperatures below -10°C, the material becomes less elastic.

  • Avoid hitting the ice.
  • After going ashore, dry the boat (condensate can freeze in the seams).
  • Use it. winter-butter (for example, Intex Protectant).
Which motor is better to put on RIB from HDPE: gasoline or electric?

The choice depends on the objectives:

  • Electric motor (up to 3 hp): Suitable for quiet fishing on the lake, pluses - quietness, minuses - limited range.
  • Gasoline engine (5-20 hp): Optimal for rivers and large bodies of water. Yamaha 9.9, Tohatsu 15.

Important: The motor must be short-dadewood (Long can damage the transom.)

How long does a RIB boat from the PND last?

The service life depends on care:

  • IHP hull10-15 years with proper storage.
  • Inflatable boards (PVC/hypalon)5-10 years (require periodic impregnation) UV protection).

Factors reducing the service life:

  • Open sun storage.
  • The motor is more powerful than the recommended one.
  • Repair of the building by non-professionals.
Can I repair the crack in the PHD myself?

Yes, but you will need special equipment:

  1. Clean the crack with sandpaper. P80.
  2. Warm the edges with a soldering iron (temperature 250-270 ° C).
  3. Fill in the crack. pyrot.
  4. Grind the seam.

For major damages (more than 5 cm), contact the service - self-repair can weaken the body.
