Choosing a reliable fishing boat or outdoor activities is a challenge that requires a balanced approach. In the inflatable boat segment, about 3.3 meters long, models with low-pressure inflatable floors, known as low-pressure inflatable boats, are particularly popular. NDMAIt's the class that belongs to. Tulin 330 NDLDIt attracts the attention of boaters with its balance between comfort, load capacity and weight.
The market offers many alternatives, but it is this model that is often the subject of fierce debate in the specialized communities, some praise it for its soft stroke and cross-country, others criticize for the specifics of the assembly. In this article, we will examine the design features, real performance and nuances of operation so that you can make a final decision.
It is important to understand that the boats NDMA So, it's very different from the classic floorboard floors, and there's no hard aluminum or plywood plates to stack and disassemble, and the whole floor is a single inflatable structure, which changes the ergonomics and the behavior of the vessel on the wave.
Design features and materials
The basis of the durability of any PVC boat is the material from which it is made. Tulin 330 It uses a five-layer reinforced fabric that combines the strength of the polyester base with the elasticity of the polyvinyl chloride coating, which provides high resistance to puncture and abrasion, which is critical for frequent landings.
⚠️ Warning: Despite the high density of the fabric, do not leave a fully pumped boat in the direct sun on a hot day unattended. Excessive pressure can lead to deformation of the seams.
The design of the cylinders is particularly noteworthy: they have complex geometry with multiple air chambers, which improves safety, if one compartment is damaged, the rest will remain buoyant, and the seams are made by hot gluing, which guarantees their tightness and durability even in an aggressive environment.
The keel in this model is also inflatable and integrated into the overall bottom system. keelinessThe hardness of the bottom is achieved by high pressure inside the cylinders of NDNDT, which can reach 0.25-0.28 Bar.
- 🚤 Five-layer reinforced PVC fabric of increased density.
- 🛡️ Reinforced cylinder linings in areas of friction.
- ⚓ Built-in inflatable keel to improve course stability.
- 🔒 Reliable valves of the "Peter" type for rapid air venting.
Stitching technology
Tulin 330 uses a two-component polyurethane adhesive that polymerizes at room temperature, creating a compound stronger than the material itself, which eliminates stratification of the seams even after years of inflating and deflection cycles.
Ergonomics and interior space
The interior of the boat is tailored to the needs of fishermen and tourists, and the spacious cockpit allows two full-equipment adult passengers to be seated. tin (seat) allows you to vary the landing, shifting the center of gravity depending on the swimming conditions.
Boat bottom, thanks to technology NDMAIt's a flat surface with no protruding elements, and it's not only convenient to move inside the cockpit, but also practical to clean, and water and sand don't get stuck in corners, like in floorboard models, but they get easily scooped out or drained out through drain valves.
The additional equipment is supported by liner rings and rod holders, which allow space to be arranged so that the gear is always at hand, but does not interfere with rowing or motor control. sonar Or you can install a navigator on a removable can, which makes them mobile.
It's worth noting that there are inflatable side stringers that do a dual function: first, they protect the cylinders from mechanical damage; second, they give the sides extra rigidity, preventing them from being blown into the cockpit when under high load or on the wave.
Driving qualities and behavior on the water
On the water. Tulin 330 NDLD It's predictable and stable. The inflatable floor acts as a shock absorber, quenching the shocks against the wave, which makes swimming much more comfortable than hard-bottom boats, especially when you're swayed, and the boat slaps less on the water and enters the wave more softly.
When going into planing with a medium-power engine (about 5-6 hp), the boat enters mode quite quickly. However, due to the shape of the inflatable floor, the angle of the differentiation can be slightly higher than that of boats with a hard redane, this is compensated by installing a transom ridge or adjusting the angle of the inclination of the motor.
⚠️ Warning: When operating with powerful motors (over 9.9 hp), be sure to use a transom plate or hydrofoil. this will help compensate for sailing and improve handling at high speeds.
The course stability of the model deserves a special mention. The long inflatable keel effectively prevents yaw, allowing you to keep a straight course with minimal operation with a tiller. On small moves, when trolling, the boat also performs excellent results by silently dissecting the water surface.
To improve glides with one person on board, try to move the seat (the jar) closer to the nose. This will change the differentiation and help the boat get on the plan faster.
Assembly, descent preparation and packaging
The process of preparing the boat for swimming is different from assembling the pitting models. You don't have to spend time laying the floor and installing the stringers. You spend most of your time pumping the cylinders and the bottom to the working pressure. You should use a foot or electric pump to do this.
The way you do it is to pump the keel (if it's separate) or the bottom, then the cylinders, and then you need to be consistent to avoid skewing, and then you need to let the boat lie down for 10 to 15 minutes and pump the air if you need to, because when you stretch the fabric, the pressure can drop.
☑️ The assembly algorithm of Tulin 330
The boat's packaging also has its own nuances, so it's compact. Tulin 330The bottom of the NDND requires careful folding so that there are no rough cloths in the same places, and regular change of the fold line will prolong the life of the material.
Comparative specifications and specifications
To assess the model’s capabilities objectively, consider its technical parameters compared to typical requirements for boats of a given class. The numbers may vary slightly depending on the year of production and the specific modification, but the basic specifications remain unchanged.
| Parameter | Meaning | Comments |
|---|---|---|
| Full length | 330 cm | Optimal for 2 people |
| Full width | 145 cm | Sustainable platform |
| Load capacity | 450 kg | Including boat weight |
| Boat weight | 38 kg | No motor or gear. |
| Recommended motor | 5-9.9 hp | 15 hp maximum. |
As you look at the chart, the weight of the boat is average for the segment, heavier than simple rowing boats, lighter than full-fledged plywood slate keel boats, and with a 450kg capacity, you can carry two people of average size, a motor, a battery and the necessary stock of equipment for a multi-day hike.
Although the passport boat can carry up to 15 hp, for comfortable and safe operation, taking into account wind load and wave, it is more reasonable to limit the range. 9.9 hp This will provide a margin of safety of the transom and cylinders.
Tulin 330 NDND is a compromise between the comfort of a soft boat and the driving qualities of a keel vessel, aimed at amateur fishermen.
Care, maintenance and durability
For a boat to last for years, it needs to be properly cared for, and after every fishing trip, especially in salt water or overgrown water, it needs to be rinsed with fresh water, which will wash away salt, sand and organics that can destroy the structure of PVC or cause corrosion of the fittings.
Store Tulin 330 It's in a dry, cool place, away from heaters and direct sunlight, and the ideal storage temperature is room temperature, and if you keep the boat in an unheated garage in the winter, make sure it's completely dry and not folded under heavy objects.
Periodically check the condition of the valves and sutures. Use a soap solution and a soft sponge to clean. Aggressive chemical solvents, gasoline or acetone can damage the protective layer of tissue, making it vulnerable to ultraviolet and mechanical influences.
⚠️ Warning: Never use abrasive powders or hard brushes to clean a boat. Microscopic scratches on the surface of PVC will become centers of crystallization of material destruction under the influence of the sun.
Small puncture repairs can be done on your own with a remplekt, which is usually included. For more serious damage, such as joints divergence, it is better to contact a specialized workshop, where you will professionally assess the degree of damage and conduct a high-quality gluing.
Frequently Asked Questions (FAQ)
Which pump is best used for the Tulin 330 NDND boat?
Any foot or electric pump is suitable for pumping a large volume of air (cylinders), but for the final pressure increase in the bottom of the NDNDT and cylinders to work 0.25-0.28 Bar, you need a pump with a pressure gauge that can create high pressure (High Pressure). Conventional car compressors may not cope with the volume or overheat.
Can this boat be used on seawater?
Yes, the materials from which it is made. Tulin 330However, after each sea voyage, the boat must be thoroughly washed with fresh water so that the salt does not crystallize in the seams and corrodes the fabric, and the aluminum accessories should be protected from corrosion.
Is the boat with the inflatable floor sailing hard?
Sailing performance on HPD boats is actually higher than on hard bottom models, because of the more rounded shapes of the cylinders and the bottom. In high side winds, this can be felt, and this effect can be compensated by properly loading, using a cat anchor, or installing transom plates to improve hydrodynamics.
What is the real speed with a 9.9 hp engine?
With a 9.9 hp engine and one driver (about 80-90 kg), the plane speed will be approximately 25-30 km / h. With two passengers, the speed will drop to 20-22 km / h. The exact figures depend on the load, the state of the screw and the hydrodynamic purity of the bottom.
