The first boat is always accompanied by a lot of legal and technical issues, among which the leading topic is mandatory registration. aluminum-boatThis is not just convenience, but also a significant saving of time and money, allowing you to focus on the very process of fishing or recreation.
The modern market offers a wide range of lightweight AMG alloy housings, whose design and weight parameters allow you to remain in the legal field without unnecessary bureaucracy. displacement boat.
In this article we will discuss in detail the technical nuances of choice, legal subtleties and practical aspects of the operation of such vessels, so that your voyage is not only pleasant, but also absolutely legal.
Legal aspects and mass restrictions
The main document regulating small craft in Russia is the Code of Administrative Offences and orders of the Ministry of Emergency Situations. The key criterion exempting the owner from registration is the total weight of the boat and the engine installed on it. aluminum-boat This limit is 200 kilograms.
It is important to understand that we are not talking about the weight of the “naked” body, which you can weigh on the household scale. Mass in curb includes the weight of the boat itself with permanent equipment, the weight of the engine assembled (with a propeller but no fuel in the tank) and the weight of the attachments installed, if it is an integral part of the structure.
⚠️ Note: GIMS inspectors may require weighing the vessel with the engine when checking documents. If the total weight exceeds 200 kg, even by 1-2 kg, failure to register will be considered a violation with a fine.
Many manufacturers indicate the weight of the body in the passport, but forget to mention the weight of the transom or reinforced elements. When assembling a set of “boat + motor” always leave a margin of 10-15 kg from the limit to avoid unpleasant situations on the water.
Design features of light aluminum housings
Aluminum-magnesium alloys, such as AMG5 or AMG6They have a unique combination of strength and lightness, and it is through the use of these materials that we can create vessels with a carrying capacity of 400-500 kg with a hull weight of only 60-80 kg, which makes them ideal candidates for the category of "unregistered".
Designably, these boats are divided into flat-bottomed (flat-bottomed) and keel. Flat-bottomed boats are lighter, more stable in calm water and cheaper to produce, but less bearable wave. Keel models, even in light design, provide better ride and handling, but their weight is often approached to the very 200 kg border.
Special attention should be paid to the quality of welds. Unlike PVC, aluminum requires professional argon welding. Tightness The hull is a safety issue, and light boats are no exception. Thin metal (1.5-2 mm) is easy to punch through with stone, so having a keel protection or removable bulwark is critical.
When buying a used aluminum boat, carefully inspect the bottom for traces of repair. Aluminum is prone to electrochemical corrosion, and poor-quality welding can lead to rapid destruction of the seam.
Choice of outboard motor for an unregistered vessel
Engine selection is a mathematical problem, where the variables are engine weight and power. To stay within 200 kg, lightweight aluminum boat owners often have to choose between compact two-strokes and modern four-stroke models.
Two-stroke engines are traditionally lighter than their four-stroke counterparts of the same power. For example, a 5 hp engine in two-stroke version can weigh about 20-22 kg, while a four-stroke engine will pull 25-27 kg. For boats with a net weight of 80 kg each kilogram counts.
- 🚤 Power up to 5 hp. The best choice for quiet fishing and short transitions, allows you to easily meet the mass limit.
- ⚓ The length of lower unit For light boats with low sides, it is critical to choose the right leg length (S or L) to avoid cavitation or burying the transom.
- 🔋 Electric motors An excellent alternative to ICE, as the weight of the engine itself is minimal, but the weight of the batteries can significantly increase the total weight of the outfitted vessel.
Remember, when calculating the mass, you take into account the weight of the motor assembly. battery For the launch or power of the sonar, its weight can also be formally considered when weighing, although in practice inspectors rarely require the battery to be weighed separately from the boat.
Can I get a motor more powerful than 5 hp?
Technically, yes, if the total weight of the vessel with this engine does not exceed 200 kg. However, for light aluminum boats this is rare, since powerful engines (10+ hp) usually weigh more than 30-40 kg, which in total with the hull gives an excess of the limit.
Comparison of popular models and their specifications
The Russian market has developed a stable segment of lightweight aluminum boats, which are in demand precisely because of the lack of registration, with manufacturers specializing in small forms of shipbuilding leading the way.
When choosing a model, you should pay attention not only to the declared weight, but also to the actual load capacity and number of seats. Often a light boat is too cramped for trophy fishing with a lot of equipment.
| Model boat | Body weight (kg) | Passengers (persons) | River power of the motor (hp) | Type of bottom |
|---|---|---|---|---|
| Salute 310 | 48 | 2 | 2.5 - 5 | Flat. |
| Kazanka-M | 65 | 3 | 5 - 8 | Flat-skinned |
| Wind 2 | 55 | 2 | 3.5 - 5 | Flat. |
| Aqua-19 | 42 | 2 | 2 - 4 | Flat. |
As you can see from the table, the lightest models (Aqua-19, Salute) leave a huge margin of weight for the installation of even a 10-horsepower engine, although their passenger capacity is limited. Kazanka-MIt requires more careful selection of the engine.
The optimal strategy is to choose a body weighing up to 70 kg, which will allow you to install a reliable four-stroke engine with a capacity of up to 6 hp and stay within 200 kg.
Operation and maintenance
Aluminum is a very unpretentious material, but it requires certain rules of operation, and the main advantage of such boats over PVC is the inability to pierc the hull with a branch or a hook, but aluminum alloys are susceptible to oxidation and electrochemical corrosion, especially in salt water.
Regularly check the condition of the anodic protection, if it is provided by the design, and the condition of the welds. After each release to the water, especially if you have been fishing in a salt reservoir or reservoir with "blooming" water, it is recommended to rinse the body with fresh water.
The boat's storage also has its own peculiarities: unlike inflatable counterparts, aluminum can be stored at negative temperatures without risk of damage, but leaving the boat in direct sunlight without a tent is not recommended - the metal is highly heated, which can cause burns and deformation of some plastic elements.
☑️ Seasonal maintenance of aluminum boats
Tuning and modernization of light boats
Owners often seek to improve their boats by installing rundooks, spinning holders and additional seats. gram-by-gram This brings you closer to the 200kg limit.
Use lightweight tuning materials. Instead of heavy plywood floorboards, you can use grooved aluminum or special composite materials. Installation of transom wheels will greatly facilitate descent into the water, but their weight (about 3-5 kg) should be considered in the general calculations.
A popular solution is to install windscreens (horses) on light flat-boats, which significantly increase comfort but increase sailing, and on a small boat with a low-powered engine, this can critically reduce speed and handling in the wind.
⚠️ Warning: Homemade metal structures welded to the body can disrupt the integrity of the corrosion coating and become hotbeds of corrosion. Use sealant bolts for attachments.
Frequently Asked Questions (FAQ)
Do I need to register a boat if the engine is more powerful than 5 hp, but the total weight is less than 200 kg?
No, according to the current legislation of the Russian Federation, registration is not required if the mass of the boat with the engine does not exceed 200 kg, regardless of the engine power, however, the engine power must not exceed the maximum permissible for the boat specified by the manufacturer.
Can I carry more than 3 people on a boat without registration?
The number of passengers is determined by the manufacturer and indicated in the boat's passport, exceeding this number is a violation of the rules for the operation of small craft and can result in a fine even if the boat is not registered.
What if weighing on the basis of GIMS weight was 203 kg?
You will be denied the right to sail without registration, either to remove some of the equipment (anchor, battery, fuel tank) from the boat to meet 200 kg, or to undergo the registration procedure, the inspectors have the right to require the weighing of the vessel with a full set of equipment.
Do I need to have the right to operate such a boat?
The license (boatmaster's license) is not required only if the boat is not subject to registration (up to 200 kg) and the engine power does not exceed 8 kW (about 10.88 hp).
