The search for a reliable watercraft often leads a boater to the idea that it is time. boat to buy armor And forget about rubber punctures, and this is especially true when standard PVC materials can't handle harsh conditions or frequent outcrops, and the market offers many options, but it's the metal case that's associated with maximum strength and durability.
However, the decision to buy requires a balanced approach, since metal is not only strength, but also a specific weight, as well as service features. Aluminum alloysThe nuances used in shipbuilding have different specifications that directly affect the life of your boat. In this article, we will discuss all the nuances of choice so that you can invest money in a truly quality product.
⚠️ Attention: Purchasing a used metal hull without careful checks for microcracks in welds can lead to the sinking of the vessel in the first season of active operation.
Advantages and Disadvantages of Metallic Body
The main argument in favor of buying a boat made of metal is its killabilityUnlike inflatables, the aluminum side is extremely difficult to damage with a snag or a sharp stone in shallow water, which allows you to safely go fishing in remote and wild places where the risk of damage to the bottom is maximum, and repair shops are hundreds of kilometers away.
However, there are downsides to these solutions, which are worth knowing about in advance: the weight of the structure is much higher than that of composite or inflatable models, which makes it difficult to transport on the roof of the car or descent into the water by hand, and the metal has high thermal conductivity and sound conductivity, which can reduce the comfort of being in a boat without proper noise insulation.
- 🛡️ High resistance to mechanical damage and abrasion of the bottom.
- ⚖️ Significant own weight, requiring a powerful motor for planing.
- 🔧 The possibility of self-welding repairs in the field.
- ❄️ Fast cooling in cold weather and heating in the sun.
Selection of alloy: duraluminum or magnesium-aluminum
When searching for a request boat to buy armor You'll come across two main types of materials: the classic duraluminium (D16T) is a time-tested aviation brand, which is very durable, but is susceptible to corrosion when in contact with salt water or galvanic vapors, and these boats require painting and protection with anodes.
Modern boats are more often made of AMG (aluminum-magnesium) alloy, which is much better corrosion resistance, more plastic and does not require such careful care of the outer surface. Welding technology For these alloys also differs, which affects the final cost of the product and the reliability of the seams in the long term.
When buying a boat made of duraluminum, be sure to check whether the internal treatment of the seams is performed with special anti-corrosion compounds, otherwise the risk of pitting corrosion is very high.
It is important to note that sheet thickness is also critical: For small boats up to 4 meters long, a sheet 2-3 mm thick is considered optimal, while larger boats carrying a powerful engine require 4-5 mm of metal. Excessive thinning to save weight often leads to cold forging and cracks.
Where is the best place to buy a boat?
There are several channels that can be found to find a reliable seller, each with its own specifications. Official dealers of manufacturing plants offer a guarantee and a choice of equipment, but the price is usually higher than average. Plants are often located in regions with a developed metallurgy, so logistics can take time.
The secondary market offers more affordable prices, but requires expert assessment of the condition. When buying a used boat, you need to pay attention to the geometry of the hull and the condition of the transom. Private ads often are full of the phrase “state of the new”, but the reality may differ.
☑️ Checking the boat before buying
Specialty boating stores often act as intermediaries, offering maintenance and installation of additional equipment, a convenient option for those who want to get a fully operational vessel on a turnkey basis without having to search for the engine and sonar themselves.
⚠️ Attention: When buying through online stores from other regions, carefully calculate the cost of delivery, since the transportation of an oversized metal case can cost up to 30% of its price.
Comparison of popular models and manufacturers
The metal boat market is represented by both large factories and small workshops. To orient in variety, it is useful to compare the technical specifications of the segment leaders. Below is a table showing the differences in dimensions and carrying capacity of popular models.
| Model | Length, m | Width, m. | Load capacity, kg | Recommended engine, hp |
|---|---|---|---|---|
| Kazanka-M | 4.5 | 1.6 | 400 | 15-20 |
| Vorjana 4.6 | 4.6 | 1.75 | 500 | 30-40 |
| Salute 4.1 | 4.1 | 1.55 | 350 | 10-15 |
| Apache 4.8 | 4.8 | 1.8 | 600 | 40-50 |
Model Kazanka It remains a classic of the genre due to the availability of spare parts and the simplicity of the design. Vorjanka or ApacheThey offer improved seaworthiness through more complex bottom geometry and increased comfort, depending on whether you plan to operate the vessel on calm reservoirs or on the wave of large rivers.
The secret of the durability of welded seams
The quality of the weld depends not only on the skill of the welder, but also on the preparation of the edges. Factory argon-arc welding (TIG) provides better tightness and strength compared to semi-automatic welding in a carbon dioxide environment, which is often used in garage conditions.
Necessary equipment and tuning
Buying a bare case is just the beginning of the journey. To be fully operational, you'll need to refit the boat, primarily for knobs that serve as seats, and aluminum knobs that are easily self-made or ordered from the manufacturer.
An important element is the installation of a transom wheel, as manually moving a metal boat along the shore is extremely difficult, and it is also worth thinking about a tent frame that protects from rain and sun, turning the boat into a full-fledged micro-boat for family holidays.
- 🎣 Installation of fishing platforms and rod holders.
- 🔋 Organization of a place for installation of the battery and the dashboard.
- 🛡️ Installation of a timber to protect the side during mooring.
- 💡 Installation of running lights according to GIMS rules.
For a metal boat weighing 200 kg, an anchor weighing at least 10-12 kg is needed to keep the boat flowing. The use of an anchor box or a special lock will prevent damage to the aluminum side by the chain when lifting the anchor.
Legal aspects and registration in GIMS
Any boat with an engine of more than 8 kW (about 10.88 hp) or a length of more than 20 meters is subject to mandatory registration. However, the rules are changing, and it is now important to monitor current legal requirements. For metal boats, the registration procedure is standard, but requires a factory passport or certificate of examination.
If you built a boat yourself or bought a garage version without documents, it will be difficult and expensive to legalize it, it will require a technical examination in a specialized organization, which can cost a lot of money, so buying a product with a full package of documents is an investment in peace of mind.
The lack of documents on the hull of the boat makes it impossible to legally register and obtain the numbers of the GIMS, which threatens fines and confiscation of the vessel.
Frequently Asked Questions (FAQ)
Do I need to paint an aluminum boat inside?
The interior is not necessarily painted if you use an AMG alloy that does not rust, but epoxy paint makes it easier to care for and wash the boat, and prevents the oxidation of aluminum, which can stain clothing and shoes.
Which motor is better for a boat with a length of 4 meters?
For a boat 4 meters long and about 1.6 meters wide, the optimal engine will be a 15-20 hp engine. This will allow you to go to the planing with one or two passengers. If you plan to fully load, you should consider options up to 30 hp, if the design of the transom allows.
Can I cook an aluminum boat by myself?
Theoretically, you can if you have argon welding machine and non-ferrous metal skills, but a violation of welding technology (overheating, improper additive material) will lead to weakening of the structure and rapid destruction of the seam.
Is the metal boat making a lot of noise on the water?
Metal conducts sound very well, so the noise from the waves and the motor will be higher than that of PVC or fiberglass, and you can reduce the noise by installing false boards, using noise insulating materials at the bottom and adjusting the engine correctly.
