Choosing a boat for small rivers and lakes often turns into a difficult compromise between cost, load capacity and maneuverability. aluminum-boat The company has long established itself as a reliable workhorse. swimmerIt attracts the attention of both beginners and experienced water engines with its accessibility and maintainability.
These boats were designed to meet the harsh operating conditions typical of the middle strip of Russia and the northern regions, and the hull design, designed to install outboard motors of various capacities, allows the vessel to be used for a variety of tasks, from quiet fishing in reeds to active planing with passengers on board. Swimmer This is not just a piece of metal, but a well-thought-out system that requires the right approach to choosing a modification.
In this article, we will discuss in detail all the nuances of ownership of this vessel, you will learn about the real driving qualities, features of the installation of attachments and the secrets of tuning, which are not always voiced in official catalogs. aluminum-alloy The safety rules will help you avoid the typical mistakes in the purchase and operation.
Structural features of the body and materials
The basis of any boat is its hull, and in the case of Swimmer This material is not chosen by chance: it has high corrosion resistance in salt and fresh water, as well as excellent weldability. The thickness of the bottom and sides varies depending on the model, but usually ranges from 2 to 4 mm, which provides the necessary safety margin in the collision with underwater obstacles.
The most important element of the design is kielson It's a longitudinal stiffening edge that runs down the center of the bottom, which gives the hull longitudinal stiffness and allows the vessel to steer confidently, especially when it's agitated. Swimmer The keelson is often made whole-welded, which eliminates the risk of its detachment when strong impacts on the bottom. On-board cylinders or inflatable elements (depending on the configuration) serve as an additional safety buffer.
The secrets of aluminum welding
The hull is welded argon-arc, a critical point, because disruption of technology can lead to micro-cracks that will only occur after a few seasons. When buying a used boat, carefully inspect the welds for oxidation.
It's worth noting the geometry of the zygomatic lines, and they're designed to minimize water resistance when you go into mode. planingHowever, the flat bottom that is common in many budget models requires caution when running at high speed against the wave. Aluminum is a sonorous material, so owners often resort to additional noise insulation, laying special mats or carpets at the bottom.
Overview of model range and specifications
Lineage Swimmer It's quite diverse and it covers the needs of different user groups, from compact two-seater models to more spacious four-seater versions with reinforced transverses, each modification has its own power limitations, which can lead to dangerous situations on the water.
To illustrate this, we'll compare the basic parameters of popular modifications, and the data in the table will help you decide on your choice based on your plans for passenger numbers and engine type.
| Model | Length, m | Width, m. | Load capacity, kg | Max, engine power, hp. |
|---|---|---|---|---|
| Swimmer-280 | 2.80 | 1.30 | 250 | 5 |
| Swimmer-320 | 3.20 | 1.40 | 350 | 10 |
| Swimmer-360 Pro | 3.60 | 1.55 | 450 | 15 |
| Swimmer-400 Fish | 4.00 | 1.60 | 550 | 20 |
Model series Fish They often have a reinforced transc for higher power motors and have special mounts for sonars and spinnings. At the same time, the basic versions may require self-refining the aft part if you plan to use heavy four-stroke engines. It is important to consider that real speed figures may differ from data-sheet figures due to load and water condition.
Operation and management on water
Management Swimmer Aluminum boats with flat bottoms are very sensitive to shifting of the center of gravity. If passengers sit on one side or the load is unevenly distributed, the boat can start to prowl or even dangerously tilt in turns. balancing The first thing you need to learn before going to the slate.
When you move against the wave, you notice the rigidity of the hull. Unlike inflatable PVC boats, the impacts on the water are transmitted to the seats and backs of passengers much more tangible. For comfortable operation, it is recommended to use soft linings on cans (seats) or purchase models with already installed hazelnuts-seats, this significantly reduces fatigue on long journeys.
⚠️ Warning: Aluminum becomes more fragile at low temperatures, avoiding heavy impacts on ice or rocks in winter, and avoiding a sharp temperature drop (for example, pouring hot water into a frozen hold for thawing), this can lead to deformation of the welds.
When it comes to maneuverability, the boat is performing well, especially when paired with a short-acting tiller. However, at high speeds (> 30 km / h), the entrance to the turn should be smooth. A sharp turn of the steering wheel at full gas can lead to a strong roll and even overkill (overturning), as the cheekbones can lose traction with water. The maximum safe speed for Swimmer models without hydrofoils is about 35-40 km / h.
Installation of outboard motor and attachment equipment
Installation of the engine on the transom Swimmer The height of the DW setup is critical for the efficiency of the propeller and the cooling of the engine. A too deep landing will increase resistance, too high will lead to air capture and overheating. The optimal position is when the anti-cavitation plate is 2-3 cm below the bottom line when driving.
For reliable fixation of the motor, use high-quality rods or bolt joints, if the design of the transom provides for it. outboard It can weaken the fastener over time, so regular bolt stretching should become a habit, and it will also be useful to install a safety cable that prevents the engine from falling into the water when the transom breaks.
☑️ Check before installing the engine
As for the equipment, Swimmer It's a great friend of sonars, navigators and anchor winches, and many owners have a special landing pad on their noses, but remember that any extra weight on their nose changes the different, causing the boat to nose-pick at speed, and you can compensate by moving fuel or passengers closer to the stern.
Tuning and modernization of the Swimmer boat
Factory equipment is often spartan, so tuning Swimmer It's a popular topic among owners. The first thing that many people start with is installation. hydrofoil This simple device stabilizes the stroke, removes yaw and allows you to go faster on the plane, which is especially true when you're fully loaded.
The second phase of modernization is comfort, and installing windshields and sun and rain awnings makes a utilitarian boat a place to relax, and replacing the regular wooden cans with soft seats with rundooks that you can store equipment inside, which is not only convenient, but also increases safety, because things don't hang down.
To reduce noise and vibration, Swimmer boats often put vibroproofing materials (vibroplastics) on the bottom and cover them with carpet or grooved aluminum on top, which also prevents the legs from slipping when the bottom is wet.
And don't forget lighting. Installing running lights, even if you don't plan to go out at night, can save lives in sudden foggy weather. LED tapes attached to the perimeter of the cockpit will help you find fallen things in the dark. The main thing is to follow the rules of wiring and use waterproof connections.
Maintenance and storage
Aluminum does not rust like steel, but is susceptible to electrochemical corrosion, especially in salt water. After each foray into a body of water, especially a sea boat, you need to rinse with fresh water. Pay special attention to the places of contact of heterogeneous metals (for example, steel bolts in an aluminum case), where corrosion develops most quickly.
When stored in the off-season Swimmer It is better to keep in an inverted position under a canopy or indoors. Direct sunlight can adversely affect the paint and seals (if any). Before wintering, it is recommended to remove all removable equipment, drain the holds and treat metal parts with conservation grease.
⚠️ Warning: Never keep a boat with the engine installed if the tank has fuel left for a long time. Gasoline loses its properties and can damage the fuel system. Pour out the residues or use fuel stabilizers before long downtime.
Regular inspection of the bottom for dents and scratches will help to identify weaknesses in time. Small damage to the aluminum case is easily brewed or repaired with special epoxy compounds for aluminum, but it is not worth delaying with this, since pressure water can gradually expand microcracks.
Frequently Asked Questions (FAQ)
Can I use a Swimmer boat at sea?
Yes, aluminum boats. Swimmer Suitable for use in seawater, subject to wave height restrictions (typically up to 0.5-0.75 m). However, after each outing into the sea, the body and engine must be thoroughly washed with fresh water to avoid corrosion.
What is the maximum weight of the boat?
The load capacity depends on the model and is indicated in the data-sheet figures (usually 250 to 550 kg). Exceeding this limit reduces the buoyancy reserve and makes the vessel unstable, which is life-threatening. Always leave a reserve of 10-15% of the maximum load.
Do I need to register a Swimmer boat with GIMS?
Registration is mandatory if the weight of the curbed vessel exceeds 200 kg or the power of the installed engine is more than 8 kW (about 10.88 hp). For low-power models with light engines, registration may not be required, but the rules may change, so it is worth clarifying the current legislation.
What speed does a boat with a 9.9 hp engine develop?
Gleaming speed for type models Swimmer-320 or 360 with an engine of 9.9 hp and one passenger is usually 25-30 km / h When fully loaded, the speed can drop to 15-20 km / h, and the boat may not go to the plane without installing a hydrofoil.
The Swimmer boat is a reliable platform, which, with proper tuning and careful attitude, will last decades, remaining relevant for fishing and family holidays.
