Choosing the first boat or replacing the old plastic trough with a modern inflatable model is always a search for a balance between load capacity, cost and comfort. Tundra 325 NDLDIt is a classic example of how a budget solution can deliver functionality previously available only in more expensive series.
abbreviation NDMA The name of the model indicates that there is a low-pressure inflatable floor, and it's not just a marketing ploy, but a major engineering feature that changes the performance and ease of assembly. Unlike plywood floorboard models, there are no rigid elements that need to be laid out and fixed, which makes the preparation for the water go much faster.
However, despite the apparent simplicity of the design, this boat has its own nuances that you need to know about before buying. Tundra 325 It is positioned as a universal vessel for fishing and relaxing on calm water, but its capabilities allow you to cope with small worries, if you choose the right equipment and engine.
Design features and materials
The basis of durability of any inflatable boat is the material. Tundra 325 NDLD This material is highly resistant to abrasion, which is especially important when in contact with rocky bottoms or sandy beaches. The density of the fabric is 850 g / m2, which is the optimal indicator for boats of this size, providing a balance between strength and weight.
The design of the sides deserves special attention, and they consist of two cylinders separated by bulkheads. safety Ensures that even if one of the compartments is punctured, the boat stays afloat, allowing the crew to reach the shore safely. Internal bulkheads also give the hull the necessary rigidity and shape, preventing the sides from deforming when loaded.
⚠️ Warning: Despite the high strength of PVC, avoid prolonged contact of inflated cylinders with hot surfaces (for example, asphalt on a hot afternoon). This can lead to local softening of the material and loss of leakage of the seams.
The seams in the model are thermally adhesive, which ensures their high reliability, and unlike stitches, there are no microscopic needle holes through which air can seep. Heat treatment creates a monolithic compound that is resistant to stratification even during intensive operation in salt water.
- 🔹 Five-layer reinforced PVC of increased density
- 🔹 Reliable heat-adhesive joints with double-adhesive
- 🔹 System of two independent inflatable compartments
- 🔹 Reinforced timber for protection against mechanical damage
Benefits of low pressure inflatable floor
The main “chip” of this model is a floor made by technology Low Pressure Air DeckUnlike the classic high-pressure inflatable floor, which requires powerful pumps and has a minimum thickness, the bottom of the NDND is pumped to less pressure, but has a greater thickness and a complex internal structure.
This has several key benefits: First, the boat is much more comfortable, you can sit right on the floor without using additional inflatable seats, because the surface is soft and warm, and second, you can improve the driving performance: the bottom acts as a shock absorber, softening the shocks against the wave, which reduces the load on the angler's spine.
And it also takes minutes to build a boat, and you don't have to mess with heavy plywood sheets that get heavier when wet, just pump the tanks and the bottom, and you often need a simple foot pump to pump the bottom, although an electric compressor will make it much easier.
Use an electric pump with auto-stop function to pump the bottom of the NDNDM. This will allow you to set an accurate pressure and not overload the pump, which can overheat when working with large volumes of air.
It's important to understand the difference in stiffness. The bottom of the NDNDM is softer than plywood paiole, but tougher than a normal inflatable floor. It's great for standing fishing, providing a stable platform. Strength of construction It is achieved by a system of internal belts-stretches, which do not allow the bottom to inflate into a ball when pressure increases.
Dimensions, load capacity and passenger capacity
Model range Tundra 325 The total length of the boat is 320 cm, and the width is 142 cm Such dimensions allow you to comfortably accommodate two adult fishermen with a full set of equipment or three passengers for short walks.
The model has a load capacity of 400 kg, enough to accommodate two people of average build, an engine, a battery, a fuel tank and the necessary fishing equipment, but it is worth remembering that the real payload depends on the weight distribution on the cockpit.
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Total length | 320 | centimeter |
| Width | 142 | centimeter |
| Load capacity | 400 | kilogram |
| Boat weight | 38 | kilogram |
| Passenger capacity | 3 | man. |
The weight of the boat itself is about 38 kg. This is the average for PVC boats of this class with an inflatable floor. Transportation in the trunk of a passenger car does not cause problems, since the packed boat has a compact size and soft packaging that can be squeezed into free space.
Compatibility with motors and driving performance
The transom part of the boat is reinforced with additional linings and is designed to install outboard motors with a capacity of up to 5 hp This is the best choice for this model. The engine of this power will allow you to reach speeds of up to 20-25 km / h with one passenger, which is enough to move along reservoirs and rivers.
Due to the shape of the cylinders and the inflatable floor, the boat has excellent seedling for planing even with minimal load. Kieliness bottom, formed by the system of stretch marks, allows you to confidently keep the course and easier to pass a small wave than on flat-bottomed models.
When you install the motor, it's important to adjust the angle of inclination of the lower unit, because the bottom is inflatable, the center of gravity can shift depending on the distribution of the load. trim (different) will save fuel and increase the maximum speed.
⚠️ Note: Do not exceed the recommended power of the motor in 5 hp Installation of a more powerful engine can lead to deformation of the transom, violation of the geometry of the body and the creation of a dangerous situation on the water.
The boat is also great for trolling fishing, and the wide cockpit allows you to set a pair of spinnings, and the soft bottom extinguishes the vibration transmitted from the motor, which makes the fishing process more enjoyable. However, it is worth considering that the sailing of inflatable sides is higher than that of rigid hulls, so with strong side winds, control can require a lot of effort.
Package and additional options
Standard equipment Tundra 325 NDLD It usually includes the boat itself, two inflatable seats (banks), carry belts, a bag-pack, a remix and a product passport. Having two cans immediately allows you to use the boat together without having to buy additional accessories.
The bow has an anchored ram, and the sides have holders for oars. Oars are usually included, but they are made of aluminum and have plastic blades. For frequent use, it is recommended to consider buying lighter and stronger oars made of fiberglass or wood.
Storage secrets
During long-term storage (winter), it is recommended to slightly release the pressure in the cylinders if the boat is stored in a heated room.
Also worth noting is the presence of cone valves, which are reliable and easy to operate, but require close care to avoid damaging the rubber seal with sand or dirt. In some versions, there may be valves such as "frog" that are more convenient for rapid pumping / deflation.
- 🔹 Package of durable fabric with webbing for carrying
- 🔹 Two inflatable seats (banks) complete
- 🔹 Aluminum paddles with plastic blades
- 🔹 Pump (often foot, less often manual double action)
- 🔹 Remake with glue and patches
Operation and care recommendations
To the boat Tundra 325 You've been in the water for years, and you have to follow a few simple rules of operation, so after every time you go out, especially if you've been fishing in salt water or standing on a sluggish bottom, you have to wash the boat with fresh water, and that will prevent the accessories from corroding and the adhesive seams from breaking down.
Drying is a critical step. Before packing in a bag, the boat must be completely dry. Even a small amount of moisture inside the package can lead to mold and an unpleasant odor that is very difficult to remove from the porous PVC. Dry the boat in the shade, avoiding direct sunlight when it is inflated.
☑️ Preparation for winter storage
When pumping a boat, use a pressure gauge. Pumped cylinders in the sun can burst, and under-pumped cylinders can deform and reduce driving performance. The optimal pressure is usually 0.2-0.25 atmospheres (check in the passport of a particular model). Remember that in the sun the pressure inside the cylinders increases, so in hot weather it is better to under-pump the boat by 10-15%.
Frequently Asked Questions (FAQ)
Can I pump the bottom of the NDND with a conventional foot pump?
Yes, you can, but it's going to take a lot of physical effort and time, and the bottom is a lot of volume, and it takes a long time to pump it with a foot pump, and you should use an electric pump with a proper nozzle or a powerful two-chamber hand pump to save time and effort.
What is the maximum weight of the Tundra 325?
Passenger carrying capacity is 400 kg. This includes the weight of passengers, motor, fuel, battery and equipment. For comfortable fishing with full gear, this reserve is optimal, leaving a small margin of safety.
Do I need to lubricate the valves with silicone?
Using silicone lubricant for rubber valve seals prolongs their life and makes it easier to twist, but make sure that the lubricant does not get on the adhesive seams and PVC fabric, as some types of lubricants can aggressively affect the material.
Is this boat suitable for fishing?
The boat is suitable for use in coastal areas, in protected bays and bays. However, the PVC and inflatable floor structure is less resistant to open sea waves and sharp shells than rigid hulls.
Tundra 325 NDND is the perfect compromise for those looking for a balance between inflatable floor comfort, compactness in transportation and affordable price without sacrificing the reliability of the main nodes.
