Choosing a first swimmer is always a balance between saving and reliability. The market is full of offers where budget models promise premium functionality, and expensive brands sometimes hide the inflated price just for the logo. Understanding the design and materials will avoid mistakes that can cost you safety on the water or extra money for repairs.
Modern flyboat It's a complex engineering product where every seam and every centimeter of fabric matters, and it's a mistake to think that all PVC models are the same, and they only differ in length, and in fact, the difference in the technology of assembling cylinders, the density of the material and the design of the transom can dramatically change the performance and the life of the product.
In this article, we will discuss all the nuances, from the choice of bottom type to the selection of the engine, so you can make an informed decision.
Materials and density: myths about the thickness of PVC
The basis of any quality boat is polyvinyl chloride, or PVCIt's a multi-layer composite material, made up of a fabric base and multiple layers of polymer coating, and it's the fabric that provides tensile strength, and the polymer layers are responsible for tightness, resistance to ultraviolet, gasoline and mechanical damage.
Often beginners look for models with maximum density, believing that the thicker the material, the better. However, blinding the numbers of 1100 g/sq.m or higher for small boats is a way to weight the structure without real need. 750-850 g/sqm from trusted manufacturers, such as Valmex or Heytex.
It is important to distinguish between the density of the material and its wear resistance: Thin but high-quality German or Korean PVC often lasts longer than the thick but cheap Chinese counterpart, which can be layered after two seasons of active use.
- 🔍 Reinforcement layer: The base is made of synthetic threads that hold shape and pressure.
- ☀️ UV protection: Special additives that prevent the destruction of the structure of the material in the sun.
- ⛽ Chemical resistance: Resistance to fuels (fuel and lubricants) and salt water.
⚠️ Attention: Cheap boats are often made of "calendar" PVC, where the layers are simply compressed, and when punctured or under intense tension, such material can deflect ("go bubbles"), which is almost impossible to properly seal in the field.
How to check the quality of PVC to the touch?
The high-quality material feels like a dense, slightly rough rubber, but does not stick to the hands. Cheap PVC can have a sharp chemical smell and too smooth "plastic" surface, which becomes brittle in the cold.
Bottom design: from inflatable to rigid
The bottom type is the main factor that influences how the boat will behave on the water. It's the floor design that determines whether you can achieve high speed or be content with a calm swaying off the shore. There are three main types of design, each with its pros and cons.
Low pressure inflatable floor (NDMA) provides maximum comfort and unsinkability, but collects a lot of water and does not allow high speed due to the sailing and shape of the bubble.plywood or aluminum) produces excellent hydrodynamics but takes assembly and drying time.
The middle ground for many anglers was the high pressure inflatable floor (see below).NDVD), often referred to as "airkecker" or "deck", it is assembled in 5-10 minutes, does not rot, does not absorb water and allows you to glid almost as well as boats with plywood peyol.
| Type of bottom | Assembly speed | Driving performance | Weight. |
|---|---|---|---|
| Inflatable (NPD) | High (5 min) | Low (not glittering) | Lung |
| Slain/Fanera | Low (20-30 min) | Excellent (planing) | Heavy. |
| Air Deck (DVD) | Average (10-15 min) | Good (planing) | Average |
| aluminum | Low (complex assembly) | Perfect. | Very heavy. |
For fishing from the shore, where the boat is stored assembled in the garage, plywood slate is ideal. For tourism and frequent trips to different water bodies, it is better to choose NDVD.
Dimensions and load capacity: calculation of stock
Size is not just a matter of comfort, it's also a matter of safety, and many people make the mistake of buying a boat "back-to-back" under their weight, and you have to consider the weight of the engine, the fuel, the battery, the gear, the anchor, and maybe the second passenger or the dog.
There's a concept passport capacityIt's a condition that's usually calculated from 180 kg per person, but the actual payload is always smaller, because the boat and the motor eat some of the weight, and if the passport says "2 person / 300 kg," it doesn't mean you can load 300 kg of payload.
The optimum safety margin should be about 20-30% of the maximum load, and if you plan to fish alone, but you like comfort and space for things, take a model designed for two, and this will also increase stability on the wave.
- 📏 Length 2.0-2.8 m: For one fisherman, rowing or motor up to 3.5 hp
- 📏 Length 2.9-3.5 m: Universal class for 1-2 people and engine 5-9.9 hp
- 📏 Length 3.6 m or more: For two adults with full load and powerful motors.
Don't forget the width of the cockpit.less than 130 cm) will be more nimble, but less stable when standing up in full height.more than 145 cm) gives a sense of security, but more powerful sails in the wind.
Cylinders and safety: valves and seams
Cylinders are the lights of your craft, and their design has a direct impact on speed, stability and durability. stitchesThere are two main methods of joining: gluing and welding.
Sticked seams are considered more reliable and maintainable. The glue penetrates the fabric structure, creating a monolithic connection. Welded seams (heat treatment) look more aesthetic, but if the technology is broken, they can disperse under load, although modern technologies (for example, at boats) Solaris or Badger) minimized the risk.
Pay special attention to valves. Petal valves are simple, but they slowly vent air. Screw valves (Switch valves)Bravo, Bomard) allow the boat to be pumped quickly and to be lowered just as quickly, which is critical when assembled in the wind or in a hurry.
⚠️ Attention: Never leave a fully pumped boat unattended in direct sunshine. When heated, the pressure inside the cylinders rises, which can cause the seams to rupture or deform the structure, especially if low-quality glue was used.
Presence quilt It's a strip of thicker material that takes on the impact of rocks and shells, protecting the main cylinders from abrasion.
Tran and motor hanging
A trawler is the back of your boat, which takes over the thrust of the engine, it can be stationary (pasted) or hinged. Inflatable boats are most often used removable transom of waterproof plywood coated with boat lacquer.
The tilt angle of the transom is critical. 15 degrees.If the angle is smaller, the boat's nose will be squeamish, if it is larger, the boat will "dig its nose" and not go well in the planing, and the angle adjustment is often done by rearranging pins or using sub-motor wedges.
For high-power engines (from 9.9 hp), it is recommended to choose models with reinforced transom, where the plywood is reinforced with metal or aluminum profiles, which prevents deflection and vibration that can destroy the attachment site to the cylinders.
☑️ Checking the transom before buying
Package and additional accessories
Buying a "naked" boat can be a nasty surprise. Often the basics do not include essentials, and the refitting results in additional costs. Always carefully read the list of what is in the bag.
The minimum required are: bag-package, remix (patch + glue), seats (banks) and oars. However, to fully operate you will also need an anchor, an anchor shaft, life jackets and, preferably, a sonar.
Pay attention to the presence stringer They put them in pockets under the cylinders, they give the bottom a stiffness, they improve fluid dynamics, they protect the bottom from puncture, and a boat without stringers on the planing will behave like a soft toy.
Buy a special glue for PVC (two-component polyurethane) immediately after buying a boat, the glue that comes in the remix is often of poor quality and is only suitable for temporary field repairs.
Frequently Asked Questions (FAQ)
How long has a quality PVC boat been in service?
With proper operation and storage (in a warm, dry place, in straightened form), the service life of a quality boat from imported PVC is 10-15 yearsCheap calendar film models may require replacement after 3-5 years of active use.
Can I keep a boat in the garage at sub-zero temperature?
Keep a assembled or deflated boat at a lower temperature -20°C PVC becomes fragile and, if handled carelessly (bending, impact), can crack. +5°C before +25°C.
Which pump is better for a boat?
A foot or electric pump is ideal for pumping large volumes of air. final pressure Electric pumps often cannot create enough pressure (250-300 mbar), and overheating kills them quickly.
What is the danger of overloading a boat?
Overload reduces the height of the boat above the water, making the boat vulnerable to flooding with the wave, and increases the area of contact of the bottom with the water, which dramatically reduces speed and increases fuel consumption, in a critical situation, this can lead to a tipping over.
Do I need to register a boat with GIMS?
According to the legislation of the Russian Federation, the registration subject to the vessel weighing more than 200 kg (in running order) OR with an engine capacity of more than 8 kW (about 10.88 hp). That is, if you have a boat weighing 150 kg and engine 9.9 hp - registration requiredIf the engine is 12 hp - registration is mandatory, regardless of the weight of the boat.
