Inflatable vessels with a length of 5 meters occupy a unique niche in the world of water transport, representing a golden mean between maneuverable two-seat “landings” and bulky four-meter boats. PVC boat 5 meters It is a fully-fledged seagoing vessel that can confidently hold the wave, carry powerful attachments and provide comfort for a team of 3-5 people. It is on this size that the segment of serious pleasure and fishing vessels begins, where the design allows you not only to sit on cylinders, but freely move around the cockpit.
The choice of a five-meter size is often due to the desire of the owner to get the maximum. loading capacity And you can still transport it in a passenger trailer, or even in the trunk of an SUV, and unlike the shorter ones, you can already install a full-fledged vehicle. stationaryIt can withstand a motor of up to 50-60 hp, which turns an inflatable boat into a high-speed plane, but this size dictates its requirements for the quality of materials and construction, because sailing and wind load increase proportionally to the area.
In this article, we will discuss in detail the technical features of the five-meter models, compare different types of bottom and discuss the nuances of choosing a motor group. cylinder diameter 55-60 cm It is a critical parameter for safety in the sea, and how to properly prepare the boat for the season, and understanding these aspects will help to avoid mistakes in the purchase, which can cost not only money, but also health on the water.
Design features and types of bottom
The basis of any inflatable boat, especially such a large one, is the type of bottom, which directly affects the driving performance and weight. For a length of 5 meters, two options are most common: NDMA (low pressure inflatable floor) and PAP The NDNDM provides excellent streamlined and gentle driving, allowing high speed even at moderate engine power, since the bottom cylinders take the form of a keel.
The soldering variants, in turn, provide a rigid platform, which is critical for fishing from a parking lot or installing heavy equipment. However, the assembly of such a boat takes much longer and requires physical effort, since the weight of the solder floor at 5 meters can reach 30-40 kg. Aluminum floor lighter than plywood, but it is colder and noisier, which should be considered when choosing.
The most important element of the design is balkThe inflatable keel balloon running along the bottom greatly improves course stability and makes it easier to go sleeve. The rigid keel built into the NDNDM design makes the boat more resistant to lateral demolition, but increases the weight when assembled.
⚠️ Warning: When operating paiole bottom boats at a five-meter length, be sure to check the condition of stringers (aluminum profiles) before each assembly. Deformation or the absence of even one element can lead to deflection of the floor under load and damage to PVC at the joints.
Capacity and passenger capacity
The five-meter boat is a serious platform, and its technical specifications allow you to carry significant cargo. loading capacity The quality of the models varies from 1000 to 1500 kg, which formally allows you to take on board up to 6-8 people, however, the actual operating load must be below the limit to maintain the buoyancy margin and the height of the board above the water.
When full loaded with people and equipment, the height of the board decreases, which increases the risk of being overwhelmed by the wave. Therefore, for a comfortable fishing or a walk on a 5-meter boat, a crew of 3-4 people with a full set of equipment is considered optimal. buoyancy It remains within safe limits and the boat retains its driving qualities.
Weight distribution is also key: Heavy batteries, tanks and anchor equipment should be placed as close to the diametric plane as possible and evenly along the length of the cockpit. Shifting the center of gravity to the nose or stern can lead to the nose burying in a wave or, conversely, to "goat" on the glides.
Selection of motor group and speed
Engine power is one of the most discussed parameters. For a boat with a length of 5 meters, the recommended power range is usually from 30 to 60 hp Motors with a capacity of 15-20 hp will allow the boat to confidently plane with only one or two passengers, while a 50-horsepower unit will bring even a full boat to the plane.
When choosing a motor, it is important to consider not only power, but also weight. Heavy four-stroke engines may require strengthening the transom or the use of additional suspension brackets to avoid overloading the aft. Two-stroke engines It is easier and easier to maintain, which is often a crucial factor for inflatable boat owners.
Speed rates are directly dependent on the shape of the cylinders and the type of bottom. Boats with narrowed nose and developed keel show the best results. Below is a table of approximate speeds for different configurations:
| Engine power (hp) | Type of bottom | Load (kg) | Speed (km/h) |
|---|---|---|---|
| 30 | NDMA | 400 | 45-50 |
| 40 | NDMA | 600 | 50-55 |
| 50 | Pilled | 800 | 40-45 |
| 60 | NDMA | 900 | 55-60 |
Materials and durability of PVC
Material quality is the foundation of safety. For five-meter boats, a dense fabric based on polyester cord mesh with bilateral PVC coating is used. The optimal density of fabric is 1100-1200 g / sq.m. The use of less dense materials is possible, but it will require an increase in the diameter of the cylinders to maintain the rigidity of the structure, which will adversely affect the performance.
Seams are the most vulnerable spot in any inflatable structure. glued Float, where strips of material are connected using two-component polyurethane adhesive, a technology that provides tightness and strength greater than the material itself. Welds, although faster in production, can be less elastic and more sensitive to impact loads in the cold.
Modern materials often have additional protections: a layer of varnish to protect against ultraviolet radiation, antibacterial impregnation and reinforcement. Teflon-coated fabric It is easier to clean from dirt and oil products, which prolongs the service life of the product. When buying, be sure to check the quality certificates and the manufacturer's warranty for the tightness of the seams.
⚠️ Warning: Never leave a fully pumped boat in direct sunlight for long periods of time unnecessarily. The air pressure inside the cylinders rises when heated, which can cause the seams to deform or even the valves to rupture, especially if the boat has been pumped "to the point" in cool weather.
Comfort and ergonomics of the cockpit
The five-meter length opens up the possibility of creating a really comfortable space, and unlike the cramped three-meter long space, you can install full-fledged spaces. backseatThe cockpit's width is an important element of ergonomics, which should allow you to move freely between banks without touching the sides.
Fishers are critically important to have comfortable linear lines, fishing rod mounts and the ability to install sonars and navigators. Many models are equipped with special areas under the sea. battery And gearboxes integrated into the design of the floor or boards, and the availability of handy handles for carrying around the perimeter of the boat also makes it easier to get to the water and ashore.
Transport and storage
Despite the impressive size of the assembled boat, the PVC boat 5 meters can still be transported in disassembled condition. the weight of the kit in packages is usually 80-110 kg, which requires the participation of two people or the use of a trolley. The dimensions of the packages allow you to place them in a large station wagon or on the roof of the car, but most often for this purpose, a trailer is used.
Storage requires a temperature regime: the optimal temperature is from +5 to +25 degrees Celsius. Storage in an unheated garage in winter is permissible, but before operation, the boat must be kept at room temperature for at least 24 hours. PVC in the cold loses elasticity, and any manipulation with it (assembly, pumping) can lead to the appearance of microcracks.
Before long-term storage (wintering), the boat must be thoroughly washed, dried and treated with a PVC preservative. Cylinders are best kept slightly flat to reduce the load on the seams, but not completely deflated to avoid cloth cloth cloth. Regular inspection and lubrication of valves is also a mandatory maintenance procedure.
How to wash a PVC boat after the season?
Use warm water and a soft sponge with neutral soap solution for washing, it is strictly forbidden to use solvents, gasoline, acetone or abrasive brushes, as they destroy the top protective layer of PVC. After washing, the boat should be thoroughly rinsed with clean water and dried in the shade before packaging.
Can I seal the boat myself in the field?
Yes, there are self-adhesive tape or tubes of glue remakes for emergency repairs, but this is considered temporary, and full restoration requires surface stripping, degreasing and using two-part glue with aging polymerization time, which is best done in stationary conditions.
How long does a PVC boat last with proper care?
The average life of a high-quality five-layer PVC boat is 10-15 years. The actual life depends on the intensity of operation, storage conditions (UV ray protection) and accuracy of handling. seams may require prevention or re-adhesion after 7-10 years of active operation.
