In the world of domestic shipbuilding aluminum-boat They have a special place in offering fishermen and hunters reliable, easy and durable solutions. boatThis small flat-bottomed boat is ideal for fishing in small water bodies, temperate rivers and lakes that do not require high speed or high wave ability. The ease of construction allows one person to easily move the vessel along the shore and load it into a car trailer or on the trunk.
The main feature of the model is the use of aviationIt's a very rusty, corrosion-resistant, minimal weight, and unlike heavy steel, the elk doesn't rust very much, although it requires careful handling when hitting rocks. It's simple, affordable, and maintainable. boat The owners appreciate it for its utilitarian nature: there is no unnecessary comfort, but there is everything you need for a quiet fishing for two.
Today, the market can be found as used copies of the Soviet era, and modern versions, often called Iaz-2 or Yaz-2MModern modifications can be distinguished by welding quality, metal thickness and additional options. However, the basic concept remains unchanged: it is a lightweight, stable flat-bottom, capable of carrying a low-power outboard motor. planeWhat are the technical parameters and how can it be improved?
Structural features and materials of the body
The basis of the longevity of the Yaz boat lies in the materials and assembly technology. aluminum-alloyIt is usually D16T grades or analogues, which are of high strength and lightness. The bottom and sides are usually 2 mm thick, which is a compromise between strength and weight. ferro-weldingIt's a powerful, sealed seam that's resistant to vibrational stress, and unlike riveted structures, welds are less prone to leakage over time if they're done well.
The design of the body is a classic flat-bottomed This geometry provides maximum deck area at a given length and excellent initial stability. In the parking lot, the boat hardly tilts, which is convenient for fishing off the board. However, on the go, especially when turning or on the wave, the flat-bottom shape dictates its limitations: the entrance to the turn must be smooth, otherwise the risk is high. overquillThe nose section usually has a slight zygomatic curve, which softens the impacts on the wave a little, but you shouldn't expect the seaworthiness of an ocean liner from the Yazya.
⚠️ Warning: The aluminum alloy used in Yaz boats is afraid of galvanic corrosion when in contact with other metals in salt water. It is not recommended to operate a boat in sea conditions. without special treatment and installation of zinc protectors.
The transom is an important element of the design, and in the basic version it is often absent or removable, which allows the boat to be used exclusively for paddles. prairie Or you order a stationary version for an outboard motor, and the trawler needs to be strengthened, because aluminum is soft and can deform when the engine vibrates, and it's also worth noting the presence of hinged bars, which not only protect the side from impact, but also serve as the basis for fastening the board. jar (Seats) and other equipment.
Technical specifications and modifications
Over the years, the Yaz boat has undergone various changes, giving rise to several modifications. The main difference lies in the dimensions and the presence of a transom for an outboard motor. Classic Yaz is a pure rowing boat, whereas versions with the index "2" or "M" are already oriented to use. outboardUnderstanding the specifications is essential for the correct selection of equipment and engine. Below is a comparative table of the main parameters.
| Parameter | Yaz (basic) | Iaz-2/Motor | Unit of measurement |
|---|---|---|---|
| Full length | 3.00 | 3.00 - 3.20 | n |
| maximum width | 1.10 | 1.20 | n |
| Height of board | 0.40 | 0.45 | n |
| Load capacity | 250 | 300 - 400 | kilogram |
| Body weight | 25-28 | 30-35 | kilogram |
The 300-400 kg load capacity allows you to comfortably accommodate two people of average build and the necessary cargo (rig, anchor, fuel reserve), but it is worth remembering that the real payload decreases with increasing water turbulence. Passport capacity The engine for such boats is usually limited to 5 hp, although some craftsmen put and 8-10 hp It is important to understand that with a powerful engine, the boat turns into an uncontrollable stool on the water due to the short base and flat bottom.
Special attention should be paid to the modification known as Yaz-N It's a specialised version with a bow cutout, designed for snorkeling, which allows the diver to comfortably get on board without turning the boat over and jump back quickly with heavy loads. These boats are often equipped with special stops and have a reinforced bottom. For the average angler, the classic version will be more versatile and safe.
Operation: Motors, control and behavior on the water
Driving a boat for an outboard motor requires certain skills, especially if you're used to keel boats or catamarans. flat-bottomIt's a very specific behavior on the water, and at low speeds, the boat is predictable and stable, but when it goes into planing (if the engine power and loading allows) or just when it's going against the wave, it starts to prowl very hard, and the steering wheel becomes very sensitive, and a sharp movement with the tiller can lead to a drift of the stern.
Used for engine installation prairie Or a stationary trayboard, and you should be weight and traction-based when you're choosing a motor, and lightweight two-stroke engines, 2-5 hp, from brands like this, would be the best choice. Tohatsu, Yamaha Four-stroke engines can be a little heavy for the stern, which will lead to a strong differentiation in the stern and reduce speed, the engine mounting must be reliable, it is desirable to use a safety rope, so that when you hit the log, you do not lose the engine.
- 🚣♂️ Rowing on the Yaz is effective due to the ease of running, but requires getting used to a low landing.
- ⚓ It is better to anchor from the nose, using an anchor-cat or an admiralty anchor, so as not to damage the thin bottom.
- 🌊 On the wave should go at an angle to the wave (bakstag) to avoid longitudinal pitching.
It's important to remember that when you're for an outboard motor, the splashes can be very splashy for passengers, because the boat's sides are not very large. spray-patter You should also be careful when mooring: aluminum is easily scratched on concrete piers or sharp stones, so having a prune or using tires as buffers is a necessity.
To reduce noise and vibration from the motor on the transom, you can glue a strip of rubber or car mat between the transom and the lower unit of the motor.
Tuning and modernization of the boat Yaz
Buying the basic version of the Yaz boat is often just the beginning of the journey. Spartan design and minimalism encourage owners to engage in the pursuit of the newest boat. tuningOne of the most popular upgrades is the installation of soft seats in rotary seats, which not only improves comfort, but also allows you to fish standing up, which is not possible on regular hard cans.
Another important element of tuning is to protect the bottom, and although aluminum is strong, frequent pulling on pebble shores or hitting snags can leave dents. Keyleston The rods, or the larch lining on the bottom, will greatly increase the life of the boat, and it's also popular to have rods in the bow to store things, which frees up space on the deck and reduces the risk of losing gear overboard.
☑️ Checklist of basic tuning Yazya
And you have to keep the safety in mind. float-block The boat that has gained water will stay afloat, allowing the crew to wait for help or turn the vessel over. Tuning often involves painting the boat bright colors (signal orange, yellow) for better visibility on the water, which is especially true when hunting or fishing in fog.
⚠️ Attention: When installing additional structures (nuts, decks), watch the centering of the boat. Shifting the center of gravity to the nose or on board can critically impair driving performance and stability.
Repair and maintenance of the aluminum case
One of the main advantages of the Yaz boat is its maintainability, unlike fiberglass, which requires specialized knowledge and materials to restore. aluminum You can brew in almost any environment, if you have access to argon welding. Small cracks or holes can often be fixed with cold welding or epoxy glue with fiberglass reinforcement as a temporary solution, but for major repairs, you better turn to professionals.
Caring for the boat is to regularly wash with fresh water, especially after use in salt water or dirty water bodies. You need to remove mud and silt, which, when drying, can create an aggressive environment. Once a season, it is recommended to inspect the welds for microcracks. If the boat is stored outside, it is advisable to cover it with an awning to minimize the impact of ultraviolet radiation on seals and painted parts, although the aluminum itself is not afraid of UV radiation.
If you notice that the boat began to "walk" or there were backlashes in the joints of cans and transoms, you need to immediately tighten the fasteners. Vibration from the engine is able to gradually unwind even well-tightened bolts. Using growers or a carving fixer (anaerobic sealant) when assembling tuning elements is a mandatory requirement. corrosion-proofingif applied, and if necessary, update it with special compositions for aluminum.
The secret of the durability of welded seams
When you repair or tuning, try not to overheat the metal. Aluminum gives off heat quickly, but local overheating can cause the alloy to change its structure and crack in the future. Use an intermittent seam.
Comparison with competitors and final conclusions
In the small boat market, the Yaz boat has competitors such as the Kazanka series boats (although they are heavier), Ob, Salute or modern inflatable models made of PVC. The main advantage of the Yaz over PVC is the inability to puncture the hull against a snag or a sharp stone, and the lack of need to dry the boat after each use. In front of steel boats, Yaz wins in weight: it can easily be carried by one person, while the steel Kazanka together is difficult to drag along the shore.
But Yazya has its drawbacks, and the main one is its low seaworthiness and comfort, and it's uncomfortable to sit on a hard can for hours, and it's no longer safe or comfortable to be in a wave above 0.5 meters. Modern PVC boats with inflatable tubes often benefit in comfort and safety, but lose in durability when they are actively operated in grassy or rocky waters.
The Yaz boat is an ideal budget option for quiet fishing on small water bodies, where ease of transportation and indestructibility of the hull are important, rather than speed and comfort.
In conclusion, it may be said that boat It's been around for decades, it's a workhorse for a fisherman who values functionality over the gloss, and with proper care and tuning, it can serve its owner faithfully for decades, even by inheritance. If you're looking for a simple, easy, reliable way to get on the water without the cost and complexity, Yaz is one of the best candidates in your garage flotilla.
Frequently Asked Questions (FAQ)
What is the maximum weight of the engine can be put on the boat Yaz?
The recommended power of the engine for the boat Yaz is up to 5 hp Installation of a more powerful engine (8-10 hp) is technically possible, but dangerous due to the short length of the hull and flat bottom. The boat can become unstable, start to prowl and even turn around. The weight of the motor should not exceed 20-25 kg, so as not to overload the tray and stern.
How many people can comfortably fit in the boat?
The passport capacity of the Yaz boat is usually 2 people, but it is most comfortable for one fisherman with a load, two adult men will be a little cramped, especially if you consider the need to accommodate gear and provide stability.
Do I need to paint an aluminum boat Yaz?
Painting a boat is not necessary, because the aluminum oxide film protects it from corrosion. However, painting (such as epoxy soils or special paints for aluminum) can improve the appearance, make the boat more visible on the water and facilitate the washing off of dirt and sludge.
Can I make a full-fledged plane out of a boat?
It's hard to turn the Yaz into a full-fledged glysser because of its flat-bottomed shape. It can go planing with one person and a light engine, but it's going to be unstable and unsafe. It needs a keeled bottom shape that classic Yaz doesn't have. Underbody upgrades are possible, but they require a high-quality welder.
Where is the best place to keep a boat in winter?
An aluminum boat is best kept in a dry, ventilated area (garage, shed) if it is not possible and the boat remains outside, it should be turned upside down, mounted on a stand (so that the bottom does not touch the ground), and covered with a waterproof awning, providing ventilation to avoid condensation inside.
