Choosing a swimmer for serious fishing or family water recreation always involves finding a balance between comfort, load capacity and mobility. In the segment of inflatable vessels with high pressure bottom (HPD), a special place is occupied by models with a length of 3.5 meters, which already allow you to feel confident in the big water. Apache 3500 NDNDM It stands out as a compromise solution that combines the rigidity of the floor and the transportability of a classic PVC boat.
This model is designed for those who are not ready to put up with the limitations of flat-bottomers, but do not plan to buy a full-fledged boat or a heavy boat with plywood peyol. High pressure inflatable floor It provides excellent performance and plane capability even with a single passenger and minimal load, and in this review we will discuss in detail the design features, real-world capabilities and nuances of operation of this vessel.
It is worth noting that the popularity of this length is due not only to the capacity, but also the possibility of installing more powerful engines, which opens new horizons for water engines. If you are considering buying a boat for long crossings or trophy fishing, the specifications of this model deserve close attention. Below we will discuss in detail what lies behind the marking 3500 and why this is important for the end user.
Structural features and materials of the body
The basis of durability of any inflatable vessel lies in the materials from which it is made. The Apache 3500 NDND hull uses a five-layer high-density PVC reinforced fabric, not just a marketing ploy, but a real need for durability in planing and rocky shores. Tissue density It is about 1100 g / sq.m., which allows you to withstand significant mechanical loads without the risk of damage to the cylinders.
The seam system deserves special attention. All joints are made by hot welding, which guarantees absolute tightness and monolithic structure. Unlike adhesive joints, welds are not afraid of changes in temperature, humidity and time. inflatable floor It is also made of a denser material, often with additional reinforcement to withstand the pressure required to give the structure a stiffness.
⚠️ Attention! When you first inflate the boat, do not immediately try to pump the cylinders to maximum pressure, heat them with warm air (for example, leaving them in the sun), or pump them gradually, allowing the material to stretch to avoid straining the seams.
The design of the sides includes a beam around the perimeter, which is not only a design element, but also an important functional part that protects the board from abrasion on the berth or side of another vessel. The bow part often provides reinforcement to anchor the beam, which is critical for fishermen practicing drift-mode fishing.
BDLT system: advantages and principle of operation
The acronym for NDND stands for "Low Pressure inflatable floor" or more commonly in the context of modern models, "High Pressure inflatable floor" (HPB), although the model name may also refer to NDND as a design type. In the case of the Apache 3500, it is a bottom that is pumped to a pressure of 0.2-0.3 atmosphere (sometimes up to 0.5-0.8 atm depending on modification), which turns the soft shell into a rigid plate that is not inferior in rigidity to plywood or aluminum.
The main advantage of this system is that there are no sleeves, so you don't have to carry heavy sleighs, stringers and look for a place to store them in the garage. Assembly of the boat This is especially true for a 3.5-meter model, where the weight of the solder version could be critical for one person.
- 🚀 Assembly speed: The time of preparation for launching is reduced by 2-3 times compared to boats with slurry.
- 🌊 Hydrodynamics: The inflatable floor creates an optimal angle of keeliness, improving germination on the wave and reducing impact loads.
- 🎒 Compactness: The assembled boat takes up a minimum of space in the trunk of the car, as it does not have rigid elements.
However, it is worth remembering that the inflatable floor is sensitive to sharp objects. puncture of the bottom on the water is a situation that requires immediate stop, although modern materials and a system of cellular structure (if applied in a particular modification) allow you to maintain buoyancy even if one section is damaged.
How to check the pressure without a pressure gauge?
If you don't have a pressure gauge, you can use the thumb method. You can press the bottom. If your finger falls more than 1 to 2 cm, the pressure is not enough. If the surface is hard as a rock and your finger doesn't push it, you've pumped the boat, which is dangerous in the heat.
Performance and driving performance
The Apache 3500 NDND is positioned as a versatile vessel capable of carrying up to 4-5 people or the corresponding cargo. loading capacity It allows two adult fishermen to comfortably accommodate with all their equipment, including sonar, anchor and gear stock, while maintaining a substantial buoyancy margin, as confirmed by safety certificates.
The boat behaves predictably on the water. The cylinders' silhouettes contribute to good course stability. When installing a motor up to 15-18 hp (the maximum recommended power for a given length and design), the vessel confidently glides even with full load. The speed at full speed can reach 30-35 km / h, which is enough to move between fishing points.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 350 cm | Overall length |
| Full width | 165-170 cm | Depends on the pressure. |
| Capacity | 4-5 people. | Passport. |
| Max, engine power. | 15-18 hp | Recommended |
| Boat weight | ~55-60 kg | Fully complete. |
An important aspect is the possibility of installation pole-transom Or integrating a transom board into cylinder design, which allows for both electric and gasoline engines, and the 3500 is very stable, allowing fishermen to stand up to throw spinning or cages.
To improve driving performance and fuel economy, adjust the boat's differential. Move the loads (battery, gearbox) closer to the nose or stern, achieving the optimal angle of lifting the bow on the planing.
Comfort and ergonomics of the cockpit
The interior of the Apache 3500 NDND is designed to meet the needs of active users, and the wide cylinders are not only sides, but also comfortable seats, often with inflatable seats, cans that can be moved around the cockpit, fixing in special seats. lyctross or mounts.
The surface of the inflatable floor is usually an "anti-slip mat" texture (often an EVA coating or a corrugated PVC surface). This ensures safe movement along the bottom even in wet shoes. For trawlers, it is important to install additional rod mounts that can be mounted on cylinders with special holders.
The bow is usually anchored and liner system for easy mooring, and the aft, in addition to the transom, often provides handles for carrying and fastening for oar holders. ergonomics The model allows you to place on board all the necessary equipment, without sacrificing free space for the legs.
☑️ Checking before getting on the water
Transport and storage
Despite its solid size in an inflated state, the assembled Apache boat 3500 NDND is a package weighing about 55-60 kg. This is the maximum weight that one person can carry over short distances, but for constant transportation alone may require a trolley or the help of a partner. The dimensions of the bag allow you to place the boat in the trunk of a station wagon or SUV, although the sedan may require the removal of the rear seat.
Storage of the boat requires a temperature regime. PVC materials do not like extremely low temperatures in a frozen state, so in winter it is better to keep the boat in a heated room or garage. In summer, you should avoid prolonged exposure to direct sunlight without need, as ultraviolet and overheating can reduce the life of the material.
⚠️ Attention! Never keep the boat deflated under heavy objects or folded for long periods of time, resulting in cloth cloth cloth and seam leaks, preferably half-inflated or loosely rolled.
Caring for the boat after each operation is to rinse with fresh water, especially if you've been swimming on a salty body of water or in water with a high content of sand. Sand, when it gets into folds, works like an abrasive and can damage the material when pumped later.
Comparison with competitors and final conclusions
There are many 3.5-meter-long models on the market, with main competitors being plywood floorboard models and inflatable floor boats from other brands. Comparison The Apache 3500 NDNDM is superior to the cleavage counterparts in assembly speed and weight, but can be inferior in floor rigidity in standing water (the hammock effect with few passengers).
Compared to cheaper models without a reinforced keel or with less dense fabric, Apache offers a margin of safety and comfort that pays off in the long run. Having a reinforced inflatable keel (in some versions) significantly improves exchange rate stability, which is critical in wind and wave.
In conclusion, the Apache 3500 NDND is the choice for a pragmatic user who values time and mobility, perfect for fishing in medium and large water bodies, family vacations, and even for use as a rescue or household vessel. If you want a workhorse that can be quickly prepared for the exit and that will not fail at a critical moment, this model is worth considering.
The Apache 3500 NDNDM is the optimal balance between the size that allows a company of 3-4 people to comfortably accommodate and the mobility available for transportation in the trunk of the crossover.
Frequently Asked Questions (FAQ)
Can the Apache 3500 NDND be used in sea conditions?
Yes, the design and materials allow the boat to be used in marine conditions (salt water), but after each sortie you need to thoroughly wash the hull with fresh water to prevent corrosion of the fittings and destruction of the PVC structure with salt.
Which motor is better for this boat?
The optimal choice will be a two-stroke or four-stroke engine with a capacity of 9.9 - 15 hp This will ensure confident planing with two passengers and cargo. 18-20 hp motors are permissible, but require caution when driving so as not to overload the transom.
How long does it take to assemble and disassemble a boat?
With experience and the use of an electric pump with blow function (for rapid deflation) and boost, assembly takes about 10-15 minutes. manual process can take 20-25 minutes depending on physical fitness.
Do I need to register a boat with GIMS?
Under current Russian law, small vessels weighing more than 200 kg (including the weight of the engine and equipment) are subject to registration. Apache’s 3500 NDND with a light engine (up to 20-30 kg) will most likely remain below the 200 kg threshold, but accurate calculation must be made by weighing a specific configuration.
