Choosing a boat for fishing or a family holiday on the water always involves finding a compromise between compactness, load capacity and comfort. Navigator 335 NDPT This is an outstanding example of engineering thinking aimed at maximizing usable space. The model developed by the Novosibirsk plant "Technologies and Materials" has long proven itself as a reliable "working tool" for lovers of water walks.
The main distinguishing feature of this series is the use of a low-pressure inflatable floor, which allows you to significantly reduce the overall weight of the structure without losing strength specifications. Navigator 335 NDLD It's not just an inflatable boat, it's a complex system where every element, from transom to stringer, plays a key role in safety and maneuverability, and in this article, we'll go into detail about why this is the number one choice for many aquatic motorists.
Design features and geometry of the body
The basis of durability of any PVC boat lies in the materials and assembly technology. Navigator 335 NDLD It is made of five-layer reinforced PVC, which is resistant to fuel, ultraviolet light and mechanical damage. Using welding technology with hot air ensures absolute tightness of joints, which is critical for water safety. The geometry of cylinders is designed to ensure maximum stability even in high waves.
Particular attention should be paid to the system. NDMA (Low Pressure inflatable floor) Unlike the classic plywood paiola, it uses a special membrane that is pumped to a pressure of 0.5 to 0.8 atmosphere, which allows you to get a hard bottom, like a metal boat, but still keep the ability to roll the product into a compact backpack. inflatable floor It also acts as an additional buoyancy, which increases the buoyancy reserve of the vessel in emergency situations.
⚠️ Attention: When pumping the bottom of the NDND, carefully monitor the pressure gauge. Pumping in hot weather can lead to rupture of the seams due to air expansion, and failure to pump - to loss of rigidity and reduced driving performance.
An important element of the design is stringerThey are inserted into pockets on the sides of the inflatable floor and serve as stiffness ribs, distributing the load from the weight of the passengers and the engine throughout the area, without which the operation of a boat with a powerful engine would not be possible, since the bottom could be bend under the influence of hydrodynamic forces.
Suture production technology
Unlike gluing, which uses glue, welding seams with hot air melts the surface layer of PVC, turning two pieces of fabric into a single monolith, which eliminates the stratification of the seam over time even when used actively in salt water.
Technical specifications of the model 335
The numbers speak for themselves when it comes to choosing a technique. Boat Navigator 335 It has dimensions that allow you to comfortably accommodate two, and if necessary three adults. length is 335 cm, and width is 156 cm Such dimensions are the "golden mean" for transportation on the trunk of a car and provide sufficient interior space.
The table below contains the main technical parameters that will help you navigate the capabilities of this model:
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Full length | 335 | centimeter |
| Full width | 156 | centimeter |
| Diameter of the cylinder | 42 | centimeter |
| Load capacity | 600 | kilogram |
| Weight of kit | 45-48 | kilogram |
It is worth noting that loading capacity 600 kg is a serious indicator, and it allows you to carry not only passengers, but also a significant supply of equipment, fuel and catch.
Comparison of modifications: ND vs. NDND
Buyers often face a dilemma: choose a classic version with a plywood bottom (see below).NDN) or modern with inflatable (NDMAThe difference between the two is fundamental and affects use scenarios: the modification of the NDNDM is easier by about 10-12 kg, making it more attractive for those who plan to assemble and disassemble the boat alone or often carry it over long distances.
In the version Navigator 335 ND It uses waterproof plywood slate, which provides a perfectly flat surface that is comfortable to walk on, and allows you to install stationary elements, such as hazelnuts or chairs on rotating bases. However, the assembly of such a boat takes longer, and the weight of the floorboards significantly increases the total weight of the kit.
Model NDMA It's a great advantage in assembly speed and comfort on the water, and the inflatable floor acts as an extra shock absorber, extinguishing the shocks of the waves, and it's especially valuable when you're running the motor against the wave, and when you're folded, it takes up less space in the trunk, because there's no rigid plywood packaging.
- 🚀 Assembly speed: NDNDM is collected faster, as it does not require stacking heavy sheets of plywood and installing stringers in the slots.
- ⚖️ Weight: The difference in weight can reach 15 kg in favor of the inflatable floor, which is critical for single transportation.
- 🌊 Driving specifications: The NDNDM is milder in wave travel, but has slightly greater water resistance due to the shape of the bottom, which may slightly reduce the maximum speed.
If you plan to move frequently between bodies of water in a passenger car without a trailer, the choice of NDND is obvious. If the boat will be stored in a garage in assembled form or used as a base for long parking lots, consider ND.
Operation and installation of the engine
Boat's trans-shipment plate Navigator 335 It's built to be able to fit outboard motors up to 15 hp, which is enough to get a boat with two passengers and loads to plane, and it's important to pick up the right engine, because an engine that's too powerful can lead to a nose buried or, conversely, to a nose snag and loss of control.
When installing the motor, balancing must be observed. The transom angle It must be adjusted by washers or hydrodynamic suspension to keep the engine's lower unit in an optimal position relative to the water surface, and improper installation can lead to cavitation and overheating of the engine.
For comfortable control, it is recommended to use low-speed and remote control when planning long transitions. The 335 provides space for installation. consoleThis allows ergonomically to place the devices and controls.

Comfort and additional options
Factory equipment Navigator 335 NDLD It usually includes everything you need to start operating: a bag, a pump, a remix and attachments. However, for a full fishing process, often requires improvements. Owners often install rod holders, anchor liners and sonar platforms.
One of the most useful options is the possibility of installing tent It's a scorching awning, and it's a way to escape the scorching sun or the sudden rain, and the balloons are designed to have arcs that are attached to a nest or that cover the cylinders.
It is also worth mentioning the possibility of installation electric-motorWith no vibrations from the ICE and compactness, electric motorswings are ideal for quiet fishing on overgrown waters. Boat 335 NHD holds its course perfectly even with a small electric motor.
⚠️ Attention: When installing additional equipment (truck box, seats), monitor the weight distribution. Shifting the center of gravity to one of the sides can significantly impair handling and increase the risk of tipping.
To protect the bottom of the NDND from puncture on rocky beaches, use a special protective mat or transport mesh that is worn on cylinders, which will prolong the life of PVC fabric.
Care, storage and durability
The service life of the boat depends on the conditions of its storage and care. PVCAlthough resistant to harsh environments, it requires simple rules: After every fishing, especially in salt water or bodies of water with abundant vegetation, the boat must be washed with fresh water and wiped dry.
Store Navigator 335 It is spread out or semi-assembled in a dry, cool place protected from direct sunlight. Prolonged exposure to ultraviolet light leads to degradation of polymer chains, loss of elasticity and the appearance of microcracks. The optimal storage temperature is from -20 to +40 degrees Celsius.
Check valves and joints regularly. Small scuffs on cylinders are a signal to consider protecting or repairing them. Timely treatment with special formulations (such as Liquid Skin or special PVC polishes) helps keep the material in excellent condition for years.
How to dry a boat after fishing?
Drying is a critical step. The moisture left inside the package can cause mold and unpleasant odors. It is best to dry the boat half-assembled, decomposing the cylinders so that air circulates from all sides. Avoid drying in direct sun on a hot day - this can lead to local overheating and deformation of the seams.
Can I leave my boat on the water for a few days?
Short-term parking (1-2 days) is acceptable if the boat is securely fixed and the water level does not change. However, prolonged exposure to water without ashore is not recommended. Constant exposure to water, especially warm water, accelerates the fouling of microorganisms, and temperature changes day and night cause cyclical expansion-compression of the air, which puts extra stress on the seams.
What is the difference between 850 g/m2 PVC and 1100 g/m2?
The number indicates the density of the material. The Navigator series boats often use dense PVC (900-1100 g/m2). The denser material holds its shape better, is less prone to stretching under load and is more resistant to puncture. However, it is heavier. For a boat 3.35 meters long, the use of dense PVC is a justified compromise to improve reliability.
What repairs can be done yourself in the field?
Small punctures (up to 3-5 mm) can be sealed with a remix, included in the package. This requires degreasing the surface, applying glue (usually polyurethane), pressing the patch and allowing it to dry under the press. Serious damage to the valves or seams requires professional repair in the workshop using special equipment.
