Choosing an inflatable boat for serious fishing or outdoor activities on the water is always a search for a balance between comfort, load capacity and mobility. In the 360 cm segment, a special place is occupied by models with low pressure inflatable bottoms, known as low pressure inflatable boats. NDMAIt is to this class belongs the popular model from the brand. OrcaIn recent years, it has become a benchmark for many water-engineers looking for a reliable alternative to the classic plywood paiola.
Why is this particular modification so exciting to the professionals? Full-fledged inflatable floor in the boat Orca 360 provides stiffness comparable to a rigid hull, but it weighs much lessThis allows for more powerful motors without critically increasing the total weight of the kit. Unlike the older models with aluminum stringers and plywood, here we are dealing with modern technology that is changing the way we build and operate.
In this article, we will discuss design features, conduct virtual running tests and discuss nuances that are often silent in advertising brochures. Orca 360 NDLD You're going to be in the middle of the wave, what's the real speed under the different engines, and whether the sheepskin is worth making if you're planning a frequent fishing trip, and get ready to dive into the technical details that will help you make an informed decision.
Design features and materials
The basis of durability of any inflatable boat lies in the material from which it is made. Orca 360 It is traditionally made from five-layer reinforced PVC fabric with a density of 900-1,100 g/m2. This is not just a marketing figure: this density provides excellent resistance to abrasion against the rocky bottom and protects against accidental puncture with branches or hooks. The seams in high-quality instances are made by double gluing with hot vulcanization, which makes them stronger than the material on the board.
The big thing about this model is, of course, the bottom structure. It uses technology. NDMA (Low Pressure inflatable floor) Unlike the inflatable keel models, the entire bottom plane is a single inflatable structure with internal partitions, which allows for a rigidity close to plywood at a pressure of just 0.2 to 0.5 atmosphere, and the boards are inflated to 0.9 to 1.0 atmosphere, creating a reliable safety buffer.
It is important to note the quality of the fittings. The boats of this class are equipped with reinforced landing beams that run around the perimeter. They not only protect the cylinders when mooring, but also serve as a convenient handle for carrying. The trunk part is reinforced with additional linings, which is critical when installing a motor up to 15-18 hp Fastenings for oars and lintel cables are also designed with a margin of strength to withstand dynamic loads on a large wave.
Suture production technology
Orca boats use a hot welding method, where the material melts and becomes monolithic, which eliminates stratification even when exposed to the scorching sun for long periods, unlike cold gluing, which can eventually float.
Advantages of inflatable floor over plywood floorboard
The controversy between hard floorboard and NDND fans has been going on for years, but the inflatable floor has a number of undeniable advantages, especially in the context of a 3.6-meter model. The first and most important thing is weight. Replacing plywood and aluminum profiles with an inflatable design reduces the total weight of the boat by 10-15 kg. For single transportation or loading into the trunk of a small car, this becomes a decisive factor.
The second important aspect is heat and noise insulation, and if you're on the water for a few hours, you'll appreciate that you don't have cold contact with aluminum or plywood, and the inflatable floor works like a thermos, keeping your body warm, which is especially true in the off-season, and there's no splashing of water on the bottom, and footsteps on that floor are almost silent, which is highly valued by anglers who hunt cautious fish.
The third thing is the speed of assembly and the compactness in the packaged form. You don't have to waste time laying out the stringers, leveling the plates and fighting the hump in the middle of the boat. Inflate the cylinders, then the bottom, and the boat is ready. Orca 360 NDLD It takes up much less space than an analogue with a hard floor, which is convenient for storage in a garage or apartment.
- 🚀 Weight loss: The absence of heavy aluminum profiles and plywood makes it easier to carry and load.
- 🔇 Silence and warmth: Perfect insulation from cold water and no noise when driving.
- 📦 Compactness: Less volume in the packaged state and no hard elements that can damage the fabric during storage.
- 🌊 Floating: The additional air volume in the bottom increases the total carrying capacity and unsinkability of the vessel.
The main advantage of the NDND in a boat 360 cm is the ability to quickly assemble a single set weighing up to 45-50 kg, which can be dragged into the trunk of the sedan, while maintaining the driving qualities of a full-fledged fishing boat.
Driving and seaworthiness
How he behaves. Orca 360 With a length of 3.6 meters and a wide enough tank, the boat has excellent germination on the wave. The design of the NDND gives the bottom the necessary longitudinal rigidity, preventing the effect of "gamachina" when the center of the boat bends under the weight of passengers, this allows you to achieve high speeds without the risk of deformation of the hull.
The cone of the cylinders and the correctly calculated angles of keeliness contribute to a confident exit to planing even with two passengers on board. The boat does not snoop on the course and is easily controlled by one movement of the hummel. However, it is worth considering that the inflatable floor, although rigid, still has minimal flexibility, so on very sharp waves, a slight “cotton” effect is possible, although much less than that of models with a simple inflatable keel.
When installing a 9.9-15 hp engine, the boat goes into planing almost instantly. With an 18 hp engine, the speed can reach 30-35 km / h with one driver, which is an excellent indicator for PVC. It is important to distribute the weight correctly: in boats with NDNDM, the center of gravity is shifted slightly differently than in the classics, so experiments with landing passengers can give an interesting result to stabilize the course.
Assembly and pumping: an algorithm of actions
Proper assembly is the key to the long service of your boat. Orca 360 BNDM has a very clear course of action, and if you break it, you can have a lot of trouble installing paiola (in this case, pumping the bottom) and skewing the structure, and you always inflate the cylinders, not to full pressure, but by about 60 to 70 percent, to straighten the folds and get the shape.
Then you start pumping the bottom, and it's important to use a pressure pump, because pumping the bottom at low temperatures (like freezing temperatures) can cause the interior partitions to rupture when the boat is brought into heat, and the bottom is pumped to the working pressure, and then the boat is allowed to stand for 10 to 15 minutes, and during that time the material is stretched and the pressure can drop a little bit, which is normal.
The final step is to finish the cylinders to the working pressure (usually 0.9 atm) and install attachments: seats, rod holders, transom plate. Do not ignore the installation of stringers, if they are provided by the design of a specific modification of the NDNDM to enhance rigidity, although in pure NDNDM their role is often performed by the internal ribs of the stiffness of the bottom itself.
☑️ Checklist of preparations for launching
specifications comparison table
For clarity, compare the technical parameters Orca 360 BND with averaged competitor scores in this size class, which will help us understand where we gain weight and where we may be sacrificing some parameters for comfort.
| Parameter | Orca 360 NDLD | Classic PVC (Phanera) | Inflatable (NDNA) |
|---|---|---|---|
| Length, cm | 360 | 360 | 360 |
| Boat weight, kg | 48-52 | 65-70 | 55-60 |
| Load capacity, kg | 650 | 600 | 550 |
| Max, engine power, hp. | 15-18 | 15-18 | 10-12 |
| Assembly time, min | 15-20 | 30-40 | 20-25 |
And you can see from the table that the main gain in weight comes from the lack of hard decking, but the load capacity remains high because of the extra air in the bottom, which makes the boat versatile: it's roomy for trophy fishing, but easy to transport.
When buying a boat with NDNDM, be sure to purchase a quality pump with two modes of operation (high volume / high pressure). Pumping such a large bottom with a foot pump is a long and tedious exercise, it is better to use an electric or powerful two-mode hand pump.
Care, storage and typical problems
Despite the high strength of the materials, Orca 360 requires proper care. PVC fears prolonged UV exposure in strained conditions and extreme temperatures. Don't leave the boat in the sun for weeks unnecessarily - this accelerates the aging of glue and fabric. After every fishing trip, especially on salt water, the boat needs to be washed with fresh water and thoroughly dried before packing.
A typical problem with all DHD boats is that you get a hump or a crease on the bottom when you pump the boat incorrectly or when you get a sharp temperature change. If you pump the boat in a warm garage and you go out into the icy water, the pressure inside will drop and the bottom may sag. Conversely, if you leave the inflated boat in the sun, the pressure will increase, which is dangerous for the seams. Always monitor the pressure with a pressure gauge in operation.
⚠️ Attention: Never dry a boat with NDNDD fully pumped in direct sunlight on a hot day. The pressure inside can exceed critical values, causing the seams to deform or the valves to rupture. Dry in the shade or by opening the valve.
Keep the boat in a straightened form or in a freely rolled-up state, without heavy objects on top. Regularly check the condition of the valves and if necessary pull them up with a special key (usually included). Small cuts and punctures are easily eliminated by remplekt, but major damage is better entrusted to professionals in the service center.
⚠️ Attention: When transporting on the roof of the car in a case, be sure to use soft crosses. Sharp edges of trunks or improperly fastened belts can wipe the fabric of cylinders in one trip at high speed.
Frequently Asked Questions (FAQ)
Can I use Orca 360 NDNDM in winter for fishing?
Yes, but with limitations. PVC material becomes tougher in the cold and less elastic; you need to pump the boat in a warm room, and in the cold the pressure will drop, which is normal; the main thing is to avoid impacts on the ice and not bend the fabric at negative temperatures, as it can crack; It is also recommended to use special winter mats to protect the bottom.
What is the maximum weight of the motor that the transom can withstand?
Standard boat transom Orca 360 designed for engines up to 15 hp, reinforced versions allow you to put up to 18-20 hp However, an important parameter is not only power, but also the weight of the engine itself.
