Choosing a boat for fishing or outdoor activities on the water often becomes a difficult dilemma between the comfort of transportation and driving performance. PVC boat with plastic bottom This is a perfect compromise, combining the lightness of the inflatable sides with the rigidity of the hull required to install the outboard motor. Unlike fully inflatable models, it uses a typed floorboard that creates a flat plane and gives the vessel stability in choppy conditions.
Many newcomers mistakenly believe that any inflatable vessel holds the load from the engine equally well, but this is not the case. The rigid bottom design allows for higher speed and fuel savings thanks to improved hydrodynamics. Trans insert In such models, it is reinforced specifically for fastening the motor of a certain power, which makes operation safe even when entering open water.
In this article, we will discuss in detail why you should pay attention to this type of construction, how to assemble the boat and what technical nuances to pay attention to when buying. Understanding the difference between paiola materials and the types of elements joining will help you avoid common mistakes and choose a truly reliable option for your goals.
Advantages of hard floorboard before an inflatable floor
The main difference that fundamentally changes the behavior of a boat on the water is that there's a hard base. plyolIt's not just a bubble, it's a full-fledged glider, which means that when you get on plane mode, the hull is flat, which reduces the drag significantly and allows the motor to operate at an optimal speed range.
In addition, the hard bottom provides a comfortable movement on the cockpit. the Fisherman does not need to balance on soft cylinders, afraid to puncture the bottom with a hook or tackle. Aluminum profiles Plastic locks that connect sections create a monolithic surface that can withstand the weight of several people and heavy equipment without deformation.
While the inflatable floor can stretch or wear away from the sand over time, rigid slabs (whether plywood or plastic) retain their geometry for years, especially for those who plan to keep the boat assembled or partially assembled without fear of loss of performance.
- 🚀 High speed: The possibility of confident planing even with low-power engines due to smooth keel.
- 🎣 Sustainability: The rigid platform allows you to safely kneel or navigate the boat while catching the trophy.
- 🛡️ Defense: The solid bottom serves as additional protection from stones and driftwood when landing on the shore.
⚠️ Attention: Don't try to reach maximum speed on a soft-floor boat, even if the power of the motor allows. The lack of a rigid support can lead to a "folding" of the transom and an emergency situation.
Types of materials for hard bottom: plastic vs plywood
When choosing a boat, the buyer is faced with the question of the material of paiola. Traditionally, marine plywood coated with a mat was used, but modern technology offers an alternative in the form of a paiola. polymericThe plastic bottom, often referred to as “plastic” or grooved plastic, has unique properties that make it preferred for certain operating conditions.
The main advantage of plastic is its absolute moisture resistance, and unlike plywood, which, when the protective layer is damaged, can dissect and gain water, increasing the weight of the boat, the plastic is inert, does not rot, does not mold, does not require annual drying and varnishing, and for regions with high humidity, this becomes a decisive factor.
But each material has its own specifications: Plywood floorboards are usually cheaper and easier to repair in the field, whereas plastic sections are more durable, but can be sensitive to extremely low temperatures, becoming brittle, depending on the conditions in which you plan to operate the vessel.
When choosing a plastic bottom, pay attention to the presence of riffling on the surface. Smooth plastic can be slippery, which is dangerous in wet weather or water entering the boat.
The comparison table will help you to quickly determine your preferences regarding the bottom material:
| Characterization | Sea plywood | Polymer plastic | Aluminum leaf |
|---|---|---|---|
| Weight. | Medium. | Highly | Low. |
| Moisture resistance | Requires care. | Absolute. | Absolute. |
| Noise | Low. | Medium | High. |
| Durability | 5-7 years | 10+ years | 10+ years |
Design features of the transom board
The trawler is the back of your boat, carrying the main load from the engine. In motor models, the trawler board is made of high-density multi-layer plywood and is sheathed with durable PVC. The key parameter here is tilt And the right angle of the trim is critical for planing and fuel economy.
Many modern models are equipped with transoms with the ability to change the inclination of the engine without the use of additional linings, this is implemented through a system of stops or movable mounts. transom It is also often provided structurally, which makes it easy to move the boat along the shore with the engine installed.
It is important to consider that the transom board must be rigidly fixed in cylinders. In high-quality boats, reinforced slings and additional pockets are used to prevent the transom from moving under load. A weak transmolant is a direct safety threat, since the engine can come off at full speed.
When you're inspecting the boat, make sure you check the quality of the transom board gluing to the cylinders. There should be no air bubbles or unpatched areas. This is where the maximum stresses are concentrated when the engine is running at high revs.
Assembly and installation of paiola: step-by-step instructions
Properly assembling a boat is a guarantee of long service and safety. The process of installing a hard bottom requires a certain sequence, so as not to damage the material of the cylinders and ensure that all elements fit tightly, you first need to partially pump the cylinders so that they take shape, but remain soft enough to fit.
Then a fabric base is laid at the bottom of the cockpit (if it is provided by the design), on top of which the sections of the paiola are laid. Stringers Longitudinal and transom profiles are inserted into the slots between sections, which is the most time-consuming stage, requiring physical effort, especially in cold weather, when the material becomes less elastic.
☑️ Boat assembly procedure
After installing all profiles, the cylinders must be finally pumped to the operating pressure specified in the data sheet (usually 0.2-0.25 atm). During the pumping process, the floorboard will straighten and become tense, forming a rigid structure. Do not pump the boat into the sun, as the pressure inside may exceed the permissible norms.
⚠️ Attention: Never walk on a boat in shoes during assembly or on water. A sharp heel or pebble on the sole can easily damage PVC fabric, especially in places of tension over stringers.
Choosing a motor for a hard bottom boat
PVC boats with rigid floorboard allow for more powerful engines than inflatable bottoms, but the choice of engine should be based not only on the wishes of the owner, but also on the technical specifications of the vessel. Maximum power permitted always indicated by the manufacturer in the marking on the transom or in the instructions.
For two-seater boats up to 3.2 meters long, the best choice will be engines with a capacity of 5-8 hp They provide confident glides with one adult and minimal load. If the boat is longer than 3.5 meters and has an inflatable keel, you can consider engines with a capacity of 9.9 hp and above, which will allow you to take on board more passengers or cargo.
Motor weight is also an important parameter: An engine too heavy on the transom of a small boat can shift the center of gravity, causing the nose to bury in a wave or difficulty controlling. Lightweight two-stroke models are often preferred for compact PVC boats, although four-strokes are more economical and quieter.
The optimum power of the engine should be 70-80% of the maximum allowed for this model boat, which will ensure the best engine life and comfortable operation without extreme loads on the transom.
When installing the motor, use only the recommended mount bolts. Standard bolts may not fit the length or pitch of the thread, causing the mounts to vibrate and unwind while driving. Regularly check the tightening of the bolts before each step out into the water.
Care and storage in the off-season
The durability of your boat depends on how you care for it. After each operation, especially in salt water, you need to thoroughly wash the boat with fresh water. The salt aggressively affects both PVC fabric and metal accessories and stringers, causing corrosion.
Keep the boat in a dry, cool place, protected from direct sunlight. Ultraviolet is the main enemy of polyvinyl chloride, causing it to aging and lose elasticity. If you can not keep the boat warm, make sure that it is completely dry to prevent mold formation and freezing of moisture residue.
Periodically, at least once a season, check the pressure in the cylinders and the integrity of the seams. To lubricate the locks of stringers and metal parts, use silicone lubricants that do not destroy rubber and plastic. Avoid petroleum-based products, as they can degrade the PVC material time.
How to dry the boat properly?
Dry the boat in the shade, partially deflated, a fully pumped boat in the sun can overheat, and a fully deflated boat will not spread the folds where moisture can remain, ideally leave it overnight in a garage with open valves.
Frequently Asked Questions (FAQ)
Can I use a plastic boat in winter?
Use is possible, but with limitations: Plastic floorboard becomes brittle at temperatures below -10 ° C. It is recommended to use such boats in moderate frosts and avoid impact loads on the bottom. PVC fabric also loses elasticity, so pump cylinders should be slightly lower pressure to avoid rupture of the seams in the cold.
What repairs are possible in the field?
Small punctures can be sealed with a special remix that comes with a kit. More serious damage to PVC fabrics will require two-part glue and a patch of the same material. Repair of stringers or plastic stoves in the field is almost impossible, so it is important to treat them carefully.
Should I lubricate the stringers?
Yes, regular lubrication of aluminum profiles with silicone lubrication facilitates the assembly and disassembly of the boat, as well as prevents oxidation of the metal and locking joints, which is especially important after contact with salt water.
What is the difference between an inflatable keel and a hard keel?
An inflatable keel (NDND) provides better seaworthiness and gentleness, but is difficult to assemble. A rigid keel (built into a floorboard or separate beam) is easier to operate, is faster to assemble, but may be less comfortable on the wave. A rigid piola boat often has an inflatable keel to combine floor stiffness and driving performance.
