When looking for a reliable and unpretentious boat for fishing or hunting, many water-engineers look at the products of the Novosibirsk Metal Service plant. However, the name of the model hides one of the most common mistakes in the small-sized boat segment. When beginners search for the query “boat ulcer aluminum specifications”, they often expect to see the specifications of the light alloy, unaware that the classic version of the model is a very simple one of the most common type of the model. Iaz Originally designed as steely boat.
However, the (demand) is conditional, and there are indeed modifications made from AMG5 aluminum-magnesium alloy on the market today, or owners change their own skin material. Understanding the difference between the two metals is critical, because it's important to understand the difference between the two metals. performanceThe weight and durability of the vessels are radically different, and in this article we will discuss in detail the actual parameters of the hull, the carrying capacity and the features of the operation of the Yazya in various modifications.
Choosing between steel and aluminum for this model is not just a matter of price, it's a choice of philosophy of operation. If you plan to keep the boat on the water all summer or drag it around often with a drag, the hull material will be the determining factor. Let's dive into the technical details so you can make an informed decision.
Design features of the body and geometry
Boat. Iaz It is a class of flat-wheeled or moderately keeled motorboats designed for use on inland water bodies. The basic design involves the presence of an all-welded body, which ensures high tightness and rigidity. Length The vessel is 3800 mm, and the width on the midsection is 1350 mm. Such dimensions allow you to comfortably accommodate on board two, and if necessary, three adult passengers with a full set of equipment.
The bottom is particularly shaped, and in the classic model, it has a V-shaped shape with a keel-like angle on the transom of about 8-10 degrees, which somewhat softens the shocks against the wave compared to flat-bottoms, but still requires careful control over large waves. Boat height of 500 mm It is optimal for fishing, allowing you to work with tackles, but may require the installation of additional leers for safety in high winds.
⚠️ Note: Despite the appearance of the modifications, the bow geometry of the aluminum versions may differ from the factory steel due to the different plasticity of the metal when flexible. Always check the real drawings before buying a non-standard version.
The transom design also deserves a special mention, and it's reinforced to accommodate outboard motors up to 10-12 hp (for the standard version) or up to 15 hp for enhanced modifications. tilt The transom must strictly comply with the recommendations of the motor manufacturer for effective gleaming.
Comparison of materials: Steel vs. Aluminium
The main question that arises from buyers is: what is better for the conditions of Russian fishing? Iaz It is traditionally made of 2 mm thick structural steel St3sp. This provides incredible survivability of the body, but turns into a significant weight - about 140-150 kg without equipment. Aluminum analogues made of the AMg5 alloy weigh about 90-100 kg, which greatly facilitates transportation on the (roof) of the car.
Corrosion resistance is another critical parameter. Aluminum doesn't rust in the usual sense of the word, it oxidizes to form a protective film. Steel requires constant monitoring of the paintwork. If you plan to leave the boat on the water (on stilts or anchor stretch marks), aluminum-alloy It is preferable, since steel in such conditions quickly loses its properties without high-quality anti-corrosion treatment.
- 🛡️ Strength: Steel is easier to penetrate with a sharp object, but harder to damage with a blunt blow to a log; aluminum is more viscous, but when hit hard can get cracked on the weld.
- ⚖️ Weight: The difference of 40-50 kg is noticeable when loading on a trailer or pulling ashore manually.
- 🔧 Repairability: Steel can be brewed in almost any garage electrode; aluminum repair requires argon welding and a qualified specialist.
Capacity and passenger capacity
One of the key specifications to look at is the load capacity. Iaz It's a 400 kg claim, which means that the boat can carry two people of medium size, a fuel tank, a battery, anchor equipment and a catch, but the actual operation makes some adjustments.
When fully loaded, the draught of the boat increases, which reduces clearance and increases the risk of encountering underwater obstacles. Passenger capacity The third passenger is a 3-person passenger, but the two are the most comfortable, and the third passenger is a significant restriction on freedom of movement, especially if you plan to do active spinning or trolling.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 3800 mm | Dimension for transportation |
| maximum width | 1350 mm | Parking stability |
| Height of board | 500 mm | Safety of landing |
| Load capacity | 400 kg | Including the weight of the people and the motor |
Weight distribution also plays a role. The design of the zygomatic frames allows for even distribution of the load, but shifting the load to one side can lead to dangerous roll, especially on the wave. Center of Gravity (CT) must always remain in the diametric plane or be as little displaced from it.
Operational and seaworthiness
Boat. Iaz It was designed for calm reservoirs, lakes and rivers with moderate currents, its seaworthiness is limited to a wave height of 0.5-0.75 meters. On a larger wave, the flat or slightly keeled bottom begins to prowl and hit the water strongly, which requires the steering wheel to constantly pay attention and work with gas. Bones The hulls help stabilize the course, but the capabilities of this class of vessels should not be overestimated.
The boat's handling depends on the installed engine. With a 5-6 hp engine, the boat barely enters planing mode with one person on board. For comfortable operation, it is recommended to use power from 8 to 10 hp When installing a more powerful engine (12-15 hp), you must strictly monitor the plane mode. Transcript boardBecause the vibrations and loads on it increase many times.
To improve seaworthiness, many owners install additional nozzles on the cheekbones or increase the kilewitness of the nose, but this requires a professional approach to welding.
Importantly, aluminum versions can behave slightly differently on the water because of their lower weight, they go faster on the plane, but also lose inertia faster when the gas is discharged, and the steel case, having a higher mass, better "holds" inertia, which sometimes helps to skip through shallow areas.
Transport and storage of the craft
The logistics issue often becomes the deciding one when buying. Iaz Weighing about 140 kg, it is practically impossible to manually load onto the top trunk of a passenger car without the use of special equipment or the help of a few strong people. trailer Or they keep the boat stationary by the water.
The aluminum variant weighing about 90 kg is already closer to the limit for two people, but still requires good physical shape for regular loading. When stored outdoors, steel requires careful preservation for the winter to avoid corrosion. Aluminum is more forgiving, but also requires protection from electrochemical corrosion, especially if other metals are nearby.
- 🚗 Transport: A trailer is mandatory for (steel); aluminum can theoretically be loaded onto the roof of an SUV.
- 🏠 Storage: Steel is afraid of moisture even in canned form; aluminum can be stored in a garage without much preparation.
- 🔥 Fire resistance: Both materials are non-combustible, which is important if there are fuel systems on board.
⚠️ Warning: When transporting on the roof of the car, make sure that the load capacity of the roof and the reliability of the mounting correspond to the weight of the boat. Excessive load can lead to deformation of the car body.
Tuning and modernization of the body
Boat owners. Iaz They often use tuning to improve consumer performance. The most popular type of modernization is the installation. console This allows you to place navigational instruments (echo sounder, GPS) and protect the helmsman from oncoming airflow and spray.
Another common upgrade is the installation of additional knobs and gearboxes, because the cockpit area is limited, any additional equipment should be as compact as possible. pyol (removable floors) made of plywood or aluminum, which makes staying in the boat more comfortable and dry.
☑️ Plan for the modernization of the boat
Some enthusiasts go further and change the configuration of the cockpit, cutting out additional niches or strengthening the transom under more powerful engines. However, any welding work on the aluminum body must be carried out in compliance with the technology, otherwise you can get a better idea. warping metal or a violation of the tightness of the seams.
Secrets of painting a metal boat
Before painting, a steel boat must be thoroughly cleaned to metal, degreased and primed with epoxy soil. Aluminum requires special adhesive primers, since ordinary paint on it is poorly maintained.
Final evaluation and selection recommendations
In summary, we can say that the boat Iaz It's a time-tested fishing tool, and despite its age and simplicity, it's still relevant because of its maintainability and affordability, and the choice between steel and aluminum depends on your priorities: if you want maximum strength and low cost, take steel. If you want weight and no corrosion, look for aluminum.
Remember that the condition of a particular used boat is often more important than the material, a rotten bottom of a steel model or cracked seams of an aluminum one will negate all the advantages of the material. surface The bottom, as this is where the defects are most often hidden.
The Yaz boat is a trade-off between price and functionality. For serious ponds and frequent operation, more modern keel models are better considered, but for quiet fishing on Yaz Lake, it remains a great choice.
Frequently Asked Questions (FAQ)
Can I put a 15 hp engine on the boat?
Technically, you can, the transom can often withstand. However, passport power is usually limited to 10-12 hp. Installing 15 hp can lead to excessive load on the body and reduce safety, especially when fully loaded.
What is the difference between the boat Kazanka?
The elk, usually narrower and lighter than Kazanka (depending on the Kazanka model), has a simpler bottom geometry. Kazankas often have more developed cheekbones and greater passenger capacity.
How to make a crack in an aluminum yap?
Aluminum repair (AMg5) requires argon arc welding (TIG) using a filler rod of the same composition. Normal electric welding can not cook, the metal will burn. It requires stripping the oxide film before welding.
How many people can I carry a boat with documents?
The boat is officially certified to carry 3 people, but it is possible to accommodate 2 full-size fishermen comfortably.
