The choice of the first or new boat always turns into a difficult dilemma when the scales are on the scales. polymer Water-powered motors with many years of experience are often divided into two camps: fans of "suvastics" and supporters of "Kazak", each arguing their position by experience of operating in various conditions, from calm lakes to turbulent Siberian rivers.
But for a newcomer to a specialty store or a forum, it can be difficult to understand the technical details: more important, ease of transportation or indestructibility of the hull? The ability to keep the wave or ease of repair in the field? The answers to these questions determine how comfortable your stay on the water will be.
In this article, we will analyze the design features of both types of boats, analyze their behavior on the water and help you make an informed choice. Aluminum can withstand direct contact with sharp stones and snags where PVC will require immediate repair or replacement of the cylinder. But is that critical to your use case? Let's get to the bottom of it.
Design features and materials of production
The basis of modern inflatable boats is reinforced polyvinyl chloride (PVC) It's not just a thin film, it's a complex composite material, made up of multiple layers of fabric with synthetic threads that take on the tear load, and between the layers of tissue is polyvinyl chloride itself, which provides leakproofness and resistance to abrasion.
Aluminum boats, or "Kazanki", are made of sheet aviation The sheets are joined either by argon welding, which creates a monolithic seam, or by riveting, and welded structures are considered more reliable and durable, because they eliminate the risk of leaking through rivet holes.
The key difference is the rigidity of the structure, and the PVC boat only gets its shape and rigidity after pumping the cylinders with air at a certain pressure, usually constituting a pressure. 0.2-0.25 atmThe aluminum case is rigid initially, regardless of external influences, which allows you to install more powerful power units on it without the risk of deformation of the transom.
Technology of cylinder production
Technology Hot Air Welding (Hot air welding) allows you to connect PVC fabrics without using glue, and the seam is stronger than the material itself, eliminating the layering during operation, which often happens with laminated boats in the budget segment.
Transportability and weight: ease of use
The undisputed leader is the boats. PVCWhen assembled, they are compact bags that can easily fit into the trunk of a passenger car, and the weight of a set with motor and gear often does not exceed 30-40 kg, allowing one person to easily carry the boat to the water.
Aluminum boats require a trailer to be transported on public roads because they do not fit the hull inside a standard car. Even small models up to 3 meters long have considerable weight and rigid geometry, making it difficult to move them manually over long distances.
But when you look at the launch preparations, that's changing, you have to pump the inflatable boat, which takes 10 to 20 minutes depending on the pump type, and the aluminum boat is ready to go, instantly, off the trailer, down on the water, and you can swim.
The seasonal factor is also important: PVC boats require careful drying before packaging, otherwise they may have mold or an unpleasant odor, and alumodox can be simply rinsed with fresh water, especially after being used in salt water, to avoid corrosion, and removed into the garage.
Capacity, load capacity and seaworthiness
When it comes to fishing with a large company or long expeditions, loading capacity Aluminum housings, especially welded ones, are able to carry significantly more payloads at the same length than inflatable ones, allowing for more powerful motors and more equipment.
The seaworthiness is directly dependent on the design of the bottom. PVC boats with an inflatable keel and a rigid floorboard floor are excellent at cutting the wave and providing comfortable riding. However, their sailing is higher, and the side wind can demolish the lightweight structure. Aluminum boats with a V-shaped bottom and cheekbones are better at lateral rolling and allow higher speeds.
An important aspect is the usable area: in an inflatable boat, some of the space is occupied by cylinders, which also restrict the movement of the fisherman inside the cockpit. In an aluminum boat, the sides are vertical or have minimal blockage, which maximizes the workspace for the fisherman.
For trophy fishing with more gear and a powerful engine, an aluminum boat will provide more options and stability on the water than a similar length of PVC.
Aluminum can be limited by its buoyancy if it tips over. inflatable tubes are guaranteed to keep the boat afloat even when fully filled with water. An aluminum boat, not equipped with additional foam buoyancy blocks, can sink or flip over, creating a dangerous situation.
Repairability and durability of materials
Durability aluminum-hull Metals are decades old, and they don't age much if they're alloyed properly and welded properly, and the only enemy is electrochemical corrosion, which occurs when different metals come into contact with water, but they're protected against it.
PVC materials are susceptible to ageing under the influence of ultraviolet light, although modern stabilizers significantly prolong the life of the fabric. The main risk for inflatable boats is mechanical damage: punctures on stones, cuts on the shell or snags. PVC repair is possible in the field with remixing and glue, but takes time for polymerization.
An aluminum boat is more difficult to repair, and if there is a severe deformation or crack in the weld, it is almost impossible to restore the sealability in the wild, requires argon welding, which is only available in specialized workshops. Small dents often do not affect the performance, but major damage can make operation impossible.
⚠️ Warning: When operating an aluminum boat in salt water, it is strongly recommended not to use steel anchors without protection or leave the boat on the water unattended for a long time. A galvanic aluminum-steel pair in an electrolyte (sea water) will lead to rapid destruction of the hull.
The service life of a high-quality PVC boat with careful operation is 10-15 years. Aluminum boats can serve 30 years or more, passing from generation to generation, unless there are critical emergencies.
Comparative analysis of boat specifications
To organize the data, we'll put the basic parameters into a single table, so we can visualize the differences and make decisions based on numbers and facts, not just subjective feelings.
| Characterization | PVC Boats | Aluminum boats |
|---|---|---|
| Weight of the body (3.2 - 3.6 m) | 40 - 60 kg | 70 - 110 kg |
| Transportation | Car trunk | Requires a trailer. |
| Resistance to puncture | Low. | High. |
| Max, engine power. | 15-20 hp. | up to 40-60 hp and above |
| Term of service | 10-15 years | 25-40 years |
As you can see from the table, the gap in weight and power is significant. If you care about speed and full-load plane, aluminum will be a big deal. If mobility and the ability to quickly build camp are the priority, PVC wins.
The cost of ownership also varies. Initial purchase price is often lower for PVC boats, but they require more frequent replacement. Aluminum boat is a long-term investment where high initial cost is amortized by years of trouble-free service.
When buying a used aluminum boat, be sure to check the integrity of the welds. Conduct a visual inspection for cracks, especially in the area of the transom and keel, where the maximum loads are concentrated.
Final selection: use cases
Choice between PVC and aluminum It doesn't have a universal answer, because it depends on the specific tasks, and if you're fishing alone or together on small bodies of water, you change seats often, and you value autonomy, the inflatable boat is the perfect companion, and it's going to get to overgrown shores, where metal can get stuck.
For family holidays, hunting with a dog, fishing on large reservoirs with strong waves and wind, as well as for use as a full-fledged vehicle on the water, the choice becomes uncontested. aluminumIt provides a sense of security and stability that is hard to get on a "suvastika."
In hot climates, inflatable boats require constant pressure monitoring, as the sun expands and can break seams, while aluminum tolerates temperature changes, although it is very hot in the sun, which can be uncomfortable when touching the board.
⚠️ Warning: Never leave a fully pumped PVC boat under direct sunlight unattended. The pressure inside the cylinders can rise to critical values, causing the seams or valves to rupture.
Ultimately, the best boat is the one that gets on the water more often. If the complicated process of preparing an aluminum boat pushes you away, you'll go fishing less often. If the fragile nature of PVC causes a constant fear of puncture, the rest won't take place either.
☑️ Criteria for the selection of a boat
Can I put a powerful motor on a PVC boat?
Theoretically, it can, but it's dangerous. PVC trawlers of boats are not designed to handle high loads and high-powered motors, and this can cause transverses to break off, cylinders to deform and lose stability. For high-powered motors, only rigid hulls are designed.
Do I need to register an aluminum boat in GIMS?
Registration is required for all small vessels weighing more than 200 kg (in running order) or with an engine power of more than 8 kW (about 10.88 hp). Lightweight aluminum boats with low-power engines often do not require registration, but the rules may change, it is worth clarifying the current regulations.
How does cold affect the material of the PVC boat?
At low temperatures (below -10°C), the PVC material becomes rigid and less elastic, which increases the risk of cracking when bending or impacting, and is possible to operate, but requires increased care and careful assembly/disassembly.
