The choice of the first or new boat for many becomes a real test when the scales are on the scales. inflatable The eternal debate over whether a RBI or an aluminum boat is better has been going on for decades on powerboating forums, each making compelling arguments based on their personal experience operating in different environments, from calm river backwaters to open sea storms.
On the one hand, inflatable boards seem vulnerable, but they offer incredible comfort and safety when faced with obstacles, and on the other hand, hard metal inspires confidence in invincibility, but requires careful handling during transportation. Your decision. It should not be based on manufacturers’ advertising, but on a clear understanding of where and how you plan to use the boat.
In this article, we will discuss in detail the design features, economic aspects and practical nuances of the operation of both types of boats. fiberglass-bottomed combination The small craft market has revolutionized, and in which cases the good old alyushka will remain out of competition.
Design features and materials
Aluminum boats, or "alouches," are made by welding or riveting sheets of aviation aluminum, often with the addition of magnesium and manganese for strength, creating a rigid hull that is virtually impossible to damage under normal operating conditions. duraluminium It perfectly holds the impacts on driftwood, rocks and sand, which makes such boats ideal for shallow water and overgrown rivers.
Rigid Inflatable Boats are hybrids, made of solid material, most often fiberglass or aluminum, and the boards are made of several inflatable sections of durable PVC fabric. Production technology RIBs are more complex because they require a sealed connection between a hard transnec and soft cylinders, and they take on the role of shock absorber when hitting a wave.
The key difference is the material's behavior when it's loaded, the metal rings and transmits vibration to the body, requiring additional noise insulation, the air in the RIB tubes absorbs the impact energy, making the stroke softer. PVC fabric It is theoretically possible to prokoot, although modern materials (for example, Hypalon or 5-layer PVC) have enormous strength.
⚠️ Note: When buying RIB, pay attention to the quality of gluing of cylinder seams. Cheap models can be layered under the influence of ultraviolet light and fuel, while aluminum housing does not have this risk.
The Secrets of Aluminum Alloys
Not all aluminum is the same. Boats use AMG alloys, which are highly corrosive in salt water, and cheap alloys can oxidize faster to form white plaque, which is easily washed away by acidic compounds.
Floating, stability and seaworthiness
In terms of safety on the water, RIBs have an undeniable advantage because of their huge buoyancy margin. Even if they flip over completely, inflatable tubes will keep the boat and crew afloat. Aluminum boats, especially flat-bottomed boats, sink instantly when filled with water, unless equipped with built-in water. float-block or additional inflatable tubes.
Stability -- the ability of a vessel to resist rolling -- is higher in RIBs because of the wide, soft sides that work like floats. It's easier to stand up full-length on a vessel like this, and the risk of injury to a hard side is minimal. Aluminum motobots They often have a narrower cockpit and rigid sides, which requires more care when moving inside the boat.
The seamlessness of RIBs makes them feel more confident in the wave. The soft side swallows impacts, reducing the load on the spine of the driver and passengers. Aluminum at high speed in choppy water (short steep wave) behaves tougher, creating a shaking effect. However, on calm water or when driving against the current. hard-keel The aluminum boat provides excellent course stability.
- 🌊 RIB: Ideal for open water, bays and places with unpredictable weather.
- 🛶 Aluminum: It is better to keep the course in straight sections of the river and with strong lateral wind.
- ⚓ Safety: RIB does not sink when rolling over, aluminum requires additional equipment.
Transportability and logistics
And here's one of the main arguments for inflatable structures: RIBs, especially mid-sized models, can be partially deflated, which reduces the dimensions of transportation on the roof of a car or in a trailer. Launching into the water RIBs often don’t require a full trailer if you use special wheel pairs or a downhill descent from a sloping shore, although a trailer is still needed for larger models.
An aluminum boat is always a monolith, it can't be folded, compressed or reduced in volume. boat-trailerRegistration of which with the traffic police is also a mandatory procedure, which creates additional logistical and financial difficulties for the owner.
But there's a caveat: it takes time to get the RIB ready to go down, you have to check the pressure in the cylinders, you have to install the console, you have to fix the engine, you can take the aluminum boat off the trailer, you have to get out of the water and leave. metal boat It's a quick win.
Operation, durability and repair
A quality aluminum case can last for decades, and it doesn't rot, it doesn't rust (as we know it), it doesn't fear temperature changes, it can be dragged across the sand, thrown on rocks, and used as a ladder. Repairs holes in the metal requires welding or special linings, which is difficult to do in the field, but the need for this occurs extremely rarely.
RIBs require more delicate handling, and although modern fabrics are strong, they are afraid of sparks from fires, sharp objects, and prolonged parking in the scorching sun (the risk of “transfer”), but repairs to RIBs can be done with remixes and glue. PVC patch It takes 30-40 minutes and keeps the pressure for years.
It's important to consider the effects of ultraviolet light and fuel. Aluminum is indifferent to gasoline, but it's better not to pour fuel on PVC fabric. It's also easier to clean the metal from dirt and mud - enough jet of water from the hose. Textile cylinders require more careful care. sinking before winter storage to avoid mold.
☑️ Post-season boat care
Economic aspect: the cost of ownership
When you first buy an aluminum boat, it often seems cheaper than a similarly sized RIB. However, the total cost of ownership ("Total Cost of Ownership") must include the price of the trailer, its maintenance, insurance and storage. For a large RIB, the trailer is also desirable, but for medium models you can do it. wheel-drive Or even hand-carrying, which saves a lot of money.
Liquidity in the secondary market is high for both types: Good aluminum is readily bought because it is “non-killable.” RIBs of well-known brands (Zodiac, Brig, Gladiator) also hold the price, but buyers are afraid of hidden fabric defects that are not always visible on inspection. Cost of repair RIB (replacement of the cylinder) can be up to 50% of the price of a new boat, while digesting the aluminum side will be cheaper.
Fuel consumption in RIBs is often lower due to streamlined shape and lower weight (at the same length). Aluminum boats, especially flat bottoms, can have greater water resistance, requiring a more powerful motor to get on plane, which increases the power of the boat. fuel.
| Parameter | aluminum boat | Boat Rib |
|---|---|---|
| Body weight | Heavyer (pure metal) | Lighter (air + plastic) |
| Transportation | Just the trailer. | trailer or roof |
| Comfort on the wave | Hard hit. | Soft move. |
| Repairability | Difficult (welding) | Just (glue/patch) |
| Price (base) | Below. | Higher. |
When calculating the budget, do not forget to add 15-20% to the cost of the boat for mandatory equipment: anchor, life jackets, insurance and registration with the GIMS.
Use cases: where and for what
The choice between RIB and aluminum should be dictated by the scenario. hunting and fishing In hard-to-reach places, where the boat has to be dragged through bushes or through rocks, aluminum is out of competition, and it can't be spoiled with branches or sharp stones. It's a working tool, a tank on the water.
If you plan a family vacation, walks with children, diving or fishing in large waters with a possible wave, the RIB will provide an incomparably higher level of comfort and safety. The ability to safely lean on the soft side, no risk of getting a bruise and better germination of the waves make it a favorite for the city. recreational.
For professional use as a tender boat for a yacht or rescue vessel, RIBs are also chosen because of their lightness and unsinkability, while aluminum reigns in the northern latitudes, where reliability and the ability to spend the night in the boat without fear of damaging the board are important.
⚠️ Note: Do not use RIBs to move on ice or moor to sharp metal structures without special cranks. The risk of a balloon cut in such conditions is maximum.
The final choice depends on the priority: absolute indestructibility and simplicity (aluminum) versus comfort, safety and compact storage (RIB).
Frequently Asked Questions (FAQ)
Can I put a more powerful engine on RIB than on aluminum?
Motor manufacturers' recommendations for RIBs are usually more stringent because of the mounting features of the transom. However, due to the lower weight, RIBs often go to the plane faster, so they need excess power less often. Always follow the marking on the transom.
How to store RIB in the winter so that the fabric does not crack?
The boat must be thoroughly washed, dried and folded in a warm room (not in a tight roll), the optimal storage temperature is from +5 to +20 degrees, and sudden temperature changes can adversely affect the adhesive seams.
Is it true that an aluminum boat doesn’t need to be registered?
Registration with GIMS depends on the weight of the boat and the power of the engine: if the weight of the curb boat (with an engine) is less than 200 kg, and the engine power is up to 8 hp (inclusive), registration is not required. This applies to both aluminum and RIBs. Aluminum boats are often heavier, so they are registered more often.
What is cheaper in the long run?
A single-boat can last 30-40 years without major repairs. RIB will require replacement cylinders after 10-15 years of active operation, which is comparable to buying a new boat.
