Choosing a swimming vehicle for fishing or a family holiday on the water is often a difficult dilemma, especially when it comes to inflatable structures with a low-pressure inflatable floor. The 3600 model occupies a unique niche between compact two-seater options and full-fledged boats, offering owners a balance between carrying capacity and transportability. NDMA (low pressure inflatable floor) allows you to create a rigid design that does not require disassembly of paioles, but at the same time retains the advantages of PVC materials.
Many water-engineers see the size of 3.6 meters as a “golden mean”, allowing you to feel confident in the wave and at the same time without problems to transport a boat in the trunk of a car. seaworthiness It is important to understand that operating such a vessel requires certain skills, especially in terms of balancing the load and selecting the power of the outboard motor.
In this article, we will take a look at all aspects of owning a 3600mm inflatable floor boat, and you will learn about the real speed, build nuances, attachments and critical safety features that are often kept quiet in advertising booklets.
Structural features and materials of the body
The basis of durability of any inflatable boat is the quality of the material used. For models of the class 3600 NDND, the de facto standard was a five-layer reinforced PVC density from 750 to 1100 g / m2. Reinforcing netThe PVC, which is embedded between the layers of polyvinyl chloride, provides high tensile strength and abrasion resistance. However, not all manufacturers use the same components: some save on the quality of the adhesive or the thickness of the outer layers, which in the long run affects the product life.
The very bottom of the low pressure is a complex structure of thousands of strands (Drop-Stitch) connecting the upper and lower surfaces. When pumped to an operating pressure of 0.2-0.25 atmosphere, the bottom becomes rigid like a plywood sheet, but remains light. V-shaped And keel shapes that effectively cut through the wave, and unlike flat bottoms, the keel provides course stability, which is critical when you're going against the wind or on the current.
⚠️ Warning: Never leave a pumped NDND boat under direct sunlight unattended for long periods of time, and the air pressure inside the cylinders and bottom increases with increasing temperature, which can cause the seams to rupture or deform the structure, even if the pressure was normal initially.
The boats are usually separated into independent compartments, which increases safety. quiltIt runs along the bottom, giving a stiffness and forming a clear forehead, which makes it easier for the boat to ride the wave and reduces the risk of splashing the cockpit.
- 🛡️ Use of five-layer reinforced PVC of increased density for protection against punctures.
- ⚓ The presence of a timber around the perimeter to protect the board during mooring.
- 🌊 Integrated inflatable keel to improve driving performance.
- 🔒 Reliable valves of the type "frog" or "petal" with protection from sand.
Dimensions, weight and transportability
With a total length of 360 cm and a width of about 160-170 cm, boats of this class have an impressive interior space. The working length of the cockpit is usually about 250-280 cm, which allows you to comfortably accommodate two or three adults with a full set of equipment. However, the main parameter for many is weight in the assemblage. NDNDNDM design excludes heavy plywood floorboard, but the inflatable floor and powerful cylinders add mass.
The average weight of the 3600 NDND varies from 55 to 70 kg depending on the density of the fabric and the configuration, which means that it will be extremely difficult to load and install on the roof of the car alone. Many models provide for splitting into two parts (cutting structure), which greatly facilitates transportation and allows you to transport the boat even in the trunk of a mid-range sedan.
Transportability is a trade-off: a whole boat is faster to assemble on the water, but requires a spacious trailer or a high-load upper trunk. A collapsible version takes time to connect the halves and seal the joint, but it benefits in logistics. It is worth considering not only your physical capabilities, but also the availability of assistants for regular trips to the reservoir.
When packaged, the boat bags take up a volume comparable to two or three backpacks, and it is important to properly pack the wet boat, allowing it to dry out to avoid mold and unpleasant smells that can get into the PVC material.
| Parameter | Meaning | Note |
|---|---|---|
| Total length | 360cm | Standard for class |
| maximum width | 165-175 cm | Affects sustainability |
| Boat weight (without motor) | 55-70 kg | Depends on the density of PVC |
| Load capacity | 600-800 kg | Taking into account passengers and cargo |
| Passenger capacity | 3-4 people. | GIMS standards |
Driving qualities and choice of motor group
A boat with a length of 3.6 meters with an inflatable floor is already a serious vessel capable of high speeds. The key factor here is the power of the outboard motor. For a confident getting on plane with one person and a minimum load, a motor with a capacity of 5-6 hp is enough. However, for full operation with two or three passengers and fishing equipment, it is recommended to consider engines with a capacity of 9.9 to 15 hp.
When installing a motor with a capacity of 15 hp and above, the boat is able to reach speeds of up to 30-35 km / h More powerful engines (18-20 hp) are also permissible, but require careful attention to the height of the transom and centering. planing At such speeds requires proper weighting: the main load should be shifted closer to the center or nose to avoid yaw and loss of controllability.
To save fuel and reduce noise at low speeds, use electronically controlled motors or two-stroke models with a reduction system. The optimal cruising speed for economical travel is about 20-22 km / h.
The height of the transom is an important aspect. The standard is 381 mm (15 inches), but some manufacturers make a 508 mm (20 inches) transom to fit more powerful long-leg motors. Installing a short-leg motor on a high transom will lead to cavitation and overheating, and a long leg on a low transom will create excess water resistance.
The 3600 NDNDM's handling at high speeds depends on the shape of the keel and the presence of zygomatic stringers. A well-designed bottom allows for cornering with minimal roll. However, it should be remembered that inflatable sides have a certain inertia, and sharp maneuvers at high speed can be dangerous.
⚠️ Warning: When operating with a motor of more than 10 hp, a safety tack (cheque) is mandatory. A sharp turn or hit an obstacle at speed can throw the driver overboard, and a boat without control can turn around and injure people in the water.
Comfort and attachments
The operation of the NDND boat is not limited to only moving on the water. For a full rest or fishing requires the installation of additional equipment. Basic equipment often includes only the vessel, the transom and the bag. Everything else - from seats to fishing rod holders - is purchased separately or ordered as an option.
One of the most useful options for boats of this size is door-wheelGiven the weight of the boat assembled with a motor (which can reach 100 kg or more), dragging it along the shore is almost impossible. Wheels mounted on a transom allow one person to easily move the boat on solid ground or sand to the water's edge.
- 🪑 Seats: Removable soft seats on transom banks or inflatable benches.
- 🎣 Tuning: Fenced fence around the perimeter for the safety of children and ease of movement.
- ⚓ Anchoring device: Installation of an anchor ditch in the bow and anchor box.
- 🔋 Electrical equipment: Installation of batteries in sealed boxes for sonar power and navigation.
Fishing is important to install brackets under the sonar and spinning holders. NDND boats often use soft cylinder linings that protect the tackle from damage and provide additional comfort when relying on the board. Also popular is the installation of an awning or running awning that protects from the sun and sudden rain, turning the boat into a small camping on the water.
Secrets of installing a sonar on the NDND
To attach the sonar sensor to the inflatable floor, it is best to use special suction cups with a quick-removal mechanism or glue the mounting back part directly to the PVC (only for experienced users). It is not recommended to use rigid brackets that cut into the cylinder, as when hitting the bottom they can damage the camera.
Assembly, maintenance and durability
The 3600 NDND takes longer to assemble than hard-bottomed models, but less time than those with complex floorboard systems. Inflatable bottoms require pumping, which is the most convenient way to do it in the field with a foot or electric pump. Using an electric pump with auto-stop or pressure control greatly simplifies preparation for descent.
Regular maintenance involves checking the pressure in the compartments, especially before long parking. PVC material is prone to thermal expansion, so in hot weather pressure can rise, and in cold weather - to fall. Pressure control It is also necessary to periodically inspect the bottom for punctures and abrasion, especially if you often moor to rocky shores.
☑️ Preparation for the season
The optimal storage temperature is between -20 and +40 degrees Celsius, but it is best to avoid extremes. Before packing for the winter, the boat must be thoroughly washed, dried and treated with a PVC protective compound that prevents the material from drying out and microcracks.
Small damage repairs (punctures up to 3-5 cm) are easily performed at home with a remix that is part of the standard delivery. It is important to degrease the surface and use a special glue for PVC, observing the temperature regime of gluing. Large damage is better entrusted to professionals in specialized workshops.
| Type of service | Frequency | Required funds |
|---|---|---|
| Pressure check | Before every exit | Manometer |
| Washing and drying | After every fishing trip | Water, soft sponge |
| Winter conservation | Once a year (autumn) | Special equipment for PVC |
| Checking the stitches | Once a season | Soap solution |
Comparison with analogues and final conclusions
The 3600 NDNDD is in a strong position in its class, competing with hard-bottomed models and smaller boats. aluminum-boatIt is superior in weight and safety (it does not sink when rolling over), but can yield in durability under extremely harsh operation (stones, sharp objects). Compared to boats 3200 mm, the model 3600 provides a significant gain in seaworthiness and capacity, but requires a more powerful and heavier engine.
The main advantage is versatility, which is suitable for both relaxing fishing on the lake, going to the coastal zone in calm weather, and for family walks, and the ability to transform space with removable elements makes it convenient for different use scenarios.
The boat 3600 NDND is the best choice for those who are looking for a balance between the comfort of a large boat and the transportability of an inflatable boat, ready to put up with a little more assembly time for the sake of the possibility of transportation in a passenger car.
When choosing a particular model, pay attention not only to the price, but also to the quality of the fittings, the presence of reinforced linings in critical places and the reputation of the manufacturer. A quality boat with proper care will last 10 years or more, becoming a reliable partner on the water.
Do I need registration in GIMS for the boat 3600 NDNDM?
Registration is required if the weight of the curbed vessel (boat + engine + regular equipment) exceeds 200 kg. Boat 3600 NDND weighs about 60 kg. If you put an engine with a capacity of up to 10 hp (weight about 30-40 kg), then the amount may not exceed 200 kg, and registration is not necessary. However, when installing the engine 15 hp and above (weight 45-50 kg) plus a full tank of fuel and equipment, you are almost guaranteed to exceed the limit of 200 kg, which will require mandatory registration and the availability of driving rights.
Which pump is best used to pump the bottom of NDND?
Low-pressure (0.2 atm) bottoms don't need a high-pressure compressor, and bivalve mode switch foot pumps or compact electric pumps (12V) powered by the car's battery are ideal, with a pressure gauge, as pumping the bottom above 0.25 atm can cause seam strain and failure to cause loss of stiffness and performance.
Can the 3600 be used in a sea wave?
The 3600 keel-bottomed NDBs are seaworthy and can be used in coastal areas, but are classified as either C (lake, reservoir, river) or D (calm water), only at wave heights of 0.6-1 meters and at least 3 miles from shore (with appropriate equipment and registration) and prohibited in stormy weather due to the risk of overturning.
