Choosing a boat to work or relax in shallow waters, swamps and overgrown bodies of water is often a challenge for a hydraulic motorist. Standard screw boats are powerless because of the risk of damaging the propeller against the grass, mud or bottom, and inflatable PVC structures do not always have sufficient load capacity and speed. boatscreated on the principle of air cushion or with an air propeller.
The Russian company Sever has been a leader in the production of such vessels for many years, offering a wide range of solutions from light single models to heavy cargo platforms. Airboats North We have proven to be a reliable tool for fishermen, hunters, environmentalists and rescue services, able to work where other equipment simply stands. In this article, we will analyze the entire range of models in detail to help you make the right choice.
The uniqueness of the design lies in the possibility of year-round operation, including movement on ice and snow, which makes them universal all-terrain vehicles. Airfield equipment This manufacturer is very easy to maintain and maintain in the field, so let's look at what modifications are available on the market today and how they differ from each other.
Series M: Classic Aeroglissers for Fishing and Hunting
Opens the model series MThese boats are designed for those who need high speed and maneuverability in open water, as well as the ability to pass hard-to-reach areas with abundant vegetation. The hull is designed with aluminum-magnesium alloy, which provides excellent performance. corrosion resistance durability even in an aggressive salty environment.
The main feature of the series is the ability to install standard gasoline engines with a capacity of up to 30 hp, which allows you to reach speeds of up to 60 km / h. The hull of the M series boats has a flat bottom with zygomatic splash-blowers, which ensures stability on the course even in strong lateral wind. These vessels are ideal for fishing expeditions, where you need to quickly reach the fishing point and return as quickly.
Inside the cockpit, there is space for equipment, anchors and additional equipment, and for the comfort of the driver and passengers, there are soft seats with anti-slip surfaces. air-glissers This series requires a certain skill of management, especially when passing corners at high speeds.
- 🚤 High permeability through overgrown reservoirs and shallow waters.
- ⚓ Reinforced transom for the installation of powerful outboard motors.
- 🛡️ Aluminum case, which does not require painting and complex maintenance.
- 👥 Capacity up to 4-5 people depending on the modification.
It is worth noting that the series M It's not designed to be able to navigate an open sea wave that's over 0.5 meters high, but rather a river and lake version that maximizes its potential, and when properly operated, these boats can last for decades, maintaining their performance.
Series C: Aircraft hovercraft
The most interesting and technological part of the model range is the series. SThese are not just boats, they're full-boats. lamb They're hovercraft that can cross not only water, but also land, ice, swamp and snow, and they're basically based on pumping air under a flexible air cushion fence (AAC), which allows the vessel to hover above the surface.
Unlike the planing models, the series of aircraft S They don't come into contact with the surface while they're driving, which completely eliminates the risk of damage to the body against rocks or ice. The propeller is pulled by the protective ring, and this makes them safe for the environment and for people who are close to the work. moverBarely.
These are operated by rudders behind the propeller or rotary deflectors, which require special training from the pilot, as the inertia of these vehicles is higher than that of conventional boats. jet-rode Going out on unequipped shore without the risk of damaging the screw or body is a crucial factor for many professionals.
The flexible air cushion fence is made of wear-resistant fabric with PVC coating, resistant to ultraviolet light and mechanical damage. In the case of damage to the RDO section, the boat does not lose buoyancy and can continue to move, although the effectiveness of the cushion will decrease. Repairability These elements allow you to quickly replace the damaged segment even in the field.
⚠️ Note: The operation of the C-Series requires a special license and the right to operate small vessels of the appropriate type, and make sure that your documents are properly executed before getting on the water.
Series A: Cargo and Specialized Platforms
For industrial needs and transportation of heavy cargo, the company "North" has developed a series of AndThese models are larger platforms with a reinforced design and a more powerful propulsion system, the main purpose of which is to deliver goods, crews of workers or equipment to hard-to-reach areas where there are no roads and no developed infrastructure.
The load capacity of such platforms can reach several tons, which makes them indispensable for the construction of facilities in marshy areas or during rescue operations. Engines. More powerful, often automotive-type or specialized aviation, running on AI-92 or AI-95 gasoline, are installed here.
The platform design allows you to install various modules: from simple sides for bulk cargo to specialized kungs for placing equipment or people. Airboats This series is often used by geologists, environmentalists and workers of the oil and gas industry.
☑️ Check before buying a cargo aircraft
An important aspect is fuel consumption, which is much higher in cargo models than in light cruising options, so you need to carefully calculate the fuel supply when planning an expedition. Autonomy swimming directly depends on the volume of fuel tanks and the engine operation mode.
Technical specifications and comparison of models
To better navigate the variety of offers, it is advisable to bring the main parameters of popular models into a single table, which will help to clearly assess the difference in size, capacity and speed specifications.
| Model | Length, m | Width, m. | Load capacity, kg | Max. speed, km/h |
|---|---|---|---|---|
| North-M | 4.6 | 1.7 | 450 | 55 |
| North-C2 | 4.8 | 2.2 | 350 | 70 |
| North-C4 | 6.0 | 2.4 | 600 | 85 |
| North-A1 | 7.5 | 3.0 | 1200 | 60 |
As you can see from the table, the series models S They have better speed performance because they don't have water resistance to the hull. And They win on payload, although they sacrifice speed for traction and stability.
When choosing a particular model, it is important to consider not only data-sheet figures, but also the actual operating conditions, for example, for family fishing on a large lake, excess load capacity may not be necessary, whereas for professional activities it becomes a critical parameter.
Engines and power plants
The power plant is the heart of any boatsThe North range uses mainly gasoline-powered internal combustion engines, and lightweight models (M and small C) often use motorcycle engines or specialized aircraft engines such as Rotax or their equivalents.
The heavier models are equipped with car engines adapted to operate in marinized conditions (although not always with full water cooling, often air or combined). Engine power varies from 50 to 150 hp depending on the class of the vessel.
Why is a propeller better than a water propeller for shallow water?
The propeller is positioned high above the body and protected by a ring, which eliminates the ingress of grass, sand and rocks that would instantly disable a conventional propeller, and the lack of contact with water reduces resistance.
It is important to monitor the quality of fuel and timely conduct maintenance Using low-octane gasoline can detonate and cause the piston group to fail, and changing candles regularly and checking the tension of the fan drive belts is a mandatory procedure before each season.
⚠️ Warning: When operating propeller-powered aeroboats, it is strictly forbidden to be in the operating zone of the propeller (back of the boat) with the engine running. The air flow can throw a person or objects with great force.
Operation and maintenance of aircraft
Possession jetboat Despite the high strength of the aluminum body, mechanical damage is possible when hitting solid objects at high speed. Flexible air cushion fence also requires careful care and protection from sparks.
After each navigation, especially in salt water, the vessel must be thoroughly washed with fresh water, which will prevent corrosion of metal elements and prolong the life of the fastener. Preservation for the winter period includes fuel drain, anticores treatment of the engine and storage in a dry room.
Regular inspection of the condition of the ROIF (flexible fence) allows you to identify the scuffs in time and seal them until the end-to-end hole is formed. Repair of fabric elements is carried out using special adhesive compounds and patches of the same material.
Legal aspects and registration in GIMS
Purchase boats According to the legislation of the Russian Federation, boats with an engine capacity of more than 8 kW (about 10.8 hp) or a length of more than 20 meters are subject to mandatory registration in the GIMS of the Ministry of Emergency Situations.
Owners must obtain license plates, register a boat and carry documents proving ownership and management, and hovercraft may require Category C or D rights depending on engine power.
Ignoring the registration rules can lead to serious fines and delay of the vessel. Therefore, it is recommended to check with the local office of GIMS the current requirements for the specific type and capacity of the equipment purchased before buying. Legality The property provides peace and security on the water.
Registration of the aircraft is mandatory if the engine power exceeds 10.8 hp or the length of the hull is more than 20 meters.
Frequently Asked Questions (FAQ)
Do you need special rights to operate the North?
Yes, if the engine power exceeds 10.8 hp, you will need the rights to operate a small vessel of the appropriate category.
Can I use an aeroboat on ice in winter?
The C series (cushion) and A series are designed for year-round use, including driving on ice and snow. The M series (planing) cannot be used in winter because they are not designed to contact ice at speed.
What is the fuel consumption of the North-C4 aircraft?
Fuel consumption depends on the load and engine mode: on average, for models with a capacity of about 100 hp, the consumption is 25-35 liters per hour when driving at full load. At cruising speed, the flow rate may be lower.
Is it difficult to repair the GOVP (skirt) in the field?
Small injuries (cuts up to 10-15 cm) can be sealed by yourself with a remix, which comes with a kit or is purchased separately. For serious damage, a section needs to be replaced, which is better done in a workshop.
Do the North's airboats have a back-up?
Most propeller models have a reversed function through an airflow redirection system (deflectors) or engine rotation, but the reversing efficiency is lower than the forward one and is used mainly for maneuvering.
