In the world of domestic water transport, there are few models that could boast the same recognition and utilitarian reliability as Radar 320 missileThis flat-bottomed AMG5 aluminium-magnesium alloy boat has become a real working tool for fishermen, hunters and coastal villagers, where depth is often measured in centimeters and the bottom is dotted with snags and stones. Its design, developed in the Soviet years, is still relevant due to its simplicity and ability to withstand extreme loads.
The main feature of the model lies in its name: radar It means "river boat," and it's 3.2 meters long, and it's the perfect size for single or double fishing, where you need maneuverability and minimum weight for drag, and unlike the larger boats, it allows you to get to the busiest shores, where other equipment will just get stuck.
The high maintenance of the hull makes this craft virtually immortal in skilled hands. The aluminum alloy that makes the hull is not corroded like steel and has enough ductility to quench impacts on obstacles without cracking. Radar 320 missile It remains in demand in the secondary market and continues to be produced in small series with minimal changes in design.
Design features and geometry of the body
The basis of the durability of this boat is its hull geometry. The flat bottom with upside down sides provides exceptional stability on standing water and allows you to pass sections with a depth of only 10-15 centimeters. The boards have a characteristic bow in the bow, which slightly improves the germination of a wave compared to the classic Kazanka, although it does not make the boat seaworthy in the full sense of the word.
To increase the rigidity of the structure on the bottom and sides are provided longitudinal and transom corrugated, these elements act as ribs of stiffness, preventing deformation of a thin sheet of metal during impacts. transom plate, designed for the installation of an outboard motor with a capacity of up to 5-6 hp, is reinforced with additional linings, which is critically important to prevent the cut of fasteners when moving.
⚠️ Note: Despite the strong alloy of AMG5, the bottom thickness is only 2 mm. When constantly operating on rocky rolls, it is recommended to install additional protection or replaceable zygomatic stripes to avoid thinning of the metal.
The bow is a sealed hazelnut, which not only serves to store things, but also serves as a forepeak, increasing the unsinkability of the vessel. The stern has ledges that facilitate landing in the boat from water or low shore, which is especially important for the elderly or when unloading heavy catches.
Technical specifications and load capacity
Understanding the physical parameters of the boat is essential for safe operation and proper equipment selection. Radar 320 missile It is a lightweight rowing boat that allows the installation of a low-power motor, and its weight in running order allows one person to carry the rolling wheel on flat ground, although the presence of a roller cart is still preferable for long transitions.
The vessel’s load capacity is officially stated to be 250 kg, but in practice this figure is directly dependent on the distribution of weight and the condition of the water surface. Excessive load leads to a decrease in the height of the board above the water, which makes the boat vulnerable to flooding even from a passing boat.
Below is a table with the main technical data that will help you decide on the choice:
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Full length | 3200 | mm |
| Midwidth | 1360 | mm |
| Height of board | 380 | mm |
| Hull mass | 45-50 | kilogram |
| Capacity | 2 | man. |
Importantly, the actual weight of the boat can vary depending on the year of production and the thickness of the rolled stock used. Older specimens often have slightly thicker sheets of metal, which increases the weight, but also increases the safety margin.
Operation and management on water
The flat bottom boat has its own specifics, different from the keel models, because of the lack of a keel and the deep V-shaped bottom. Radar 320 missile It has sailability and a tendency to drift in lateral winds, and it doesn't cut the wave but it flops on it while it's on the move, requiring the operator to be constantly ready to hit and roll.
When installing the motor, you must strictly observe the centering. Shifting the engine or passengers closer to the transom or nose can dramatically change the trim, the optimal position is when the boat goes with a slight roll on the nose, but the transom does not sink into the water, creating turbulent flows.
To improve the course stability in shallow water experienced boaters recommend installing small zygomatic linings or "lyces" on the transom, which help stabilize the course when moving against the current.
The boat with a single passenger and a 5 hp engine comes out quite confidently, but with a full load, the transition to planing can be difficult. In such cases, it is better to move on displacement mode, saving fuel and reducing the risk of breaking the lower unit on underwater obstacles.
Maintenance and protection against corrosion
Although AMG5 is highly corrosive, aggressive environments, especially salt water or contaminated industrial runoff, can eventually destroy the metal. Aluminum’s main enemy is electrochemical corrosion, which occurs when it comes into contact with other metals, such as steel bolts or copper wiring.
Regular inspection of the case after each season is mandatory, and special attention should be paid to the places where the jars, the slab and the hinges are attached. This is where moisture and dirt that cause oxidation most often accumulate, and if you notice white plaque or paint bloating, you should immediately clean these places to metal.
⚠️ Warning: Never use paints that contain lead or copper to paint an aluminum case. These metals will create a galvanic pair that will accelerate the destruction of aluminum at times. Use only special soils for non-ferrous metals.
To protect the bottom, epoxy compounds or polyurethane enamels are often used. Before painting, the surface should be perfectly oxidized and defatted. Quality painting not only improves the appearance, but also reduces algae fouling, which has a positive effect on speed.
Tuning and modernization of the missile boat
Owners Radar 320 missiles They often don't stop at factory designs to improve comfort and functionality. One of the most popular types of tuning is the installation of soft seats with backs, because regular wooden cans are inconvenient for long fishing.
To improve safety, many install additional buoyancy blocks in the form of sealed boxes under the seats, which keeps the boat afloat even in the event of a serious breach or rollover, and upgrades often involve lighting and navigation.
☑️ Plan for the modernization of the boat
An interesting solution is to install a rotary chair on a pedestal in the center of the boat, which allows you to fish with spinning in the plumb, but such an upgrade requires careful calculation of the center of gravity, so as not to disturb the stability of the vessel.
The Secret to Sustainable Painting
Before applying the finishing layer of paint, experienced craftsmen recommend heating the body with a building hair dryer to 40-50 degrees. This allows you to remove micromoisture from the metal pores and provides better adhesion of the coating.
Comparison with analogues and choice of accessories
There are several direct competitors in the market. Radar 320 missilesAmong which are the boats series "Kazanka" and various models of PVC. The main advantage of the Rocket before PVC - the inability to pierce the hull on a sharp branch or stone, and before steel boats - less weight and lack of rust.
When choosing accessories, you should focus on specialized stores that offer products for small craft. Cat anchors or low-weight plow anchors will be most effective for this type of bottom and size of the boat.
In conclusion, this boat is a pragmatic choice, it will not bring comfort to the yacht, but will deliver where others are afraid to go, and the right care and intelligent modernization make a simple aluminum box a reliable companion for years to come.
The main advantage of the Radar-320 is the combination of minimal precipitation and high strength, which makes it an uncontested leader for fishing in overgrown and shallow areas of rivers.
Frequently Asked Questions (FAQ)
What is the maximum speed of the RL-320?
With a motor of 5 hp and one passenger, the speed can reach 20-22 km / h. At full load, the speed drops to 10-12 km / h, and the boat goes to displacement mode.
Can I register this boat with the GIMS?
Yes, a boat is subject to registration if its mass in running order exceeds 200 kg or if the engine is planned to be installed more than 8 hp (or 10 hp depending on the current regulations and year of manufacture), however, many use them without registration, observing the rules of navigation for rowing vessels.
Do I need to lubricate aluminum casing with oil for the winter?
No, you don't have to oil it, you just have to wash the boat thoroughly with fresh water, dry it and store it upside down under a canopy or in a dry room to avoid condensation.
Will the boat withstand a hit on a rock at speed?
Aluminum alloy AMG5 is highly viscosity, so it's more likely to remember when impacted than crack, but a strong impact at high speed can break the tightness of welds, so it's better to dump gas in shallow water.
