Choosing a swimming aid for fishing or water recreation is often a daunting task, especially when the budget is tight and reliability requirements are high. Biriusa boat 325 NDND It is well-deservedly popular among water lovers, offering a trade-off between price and functionality, and is a classic example of a rowing boat that can be powered by a motor if desired, making it versatile for a variety of use cases.
abbreviation NDMA The model name indicates the presence of an inflatable floor, which is a key difference from plywood flatbeds, which makes it easy to transport gear in the trunk of a passenger car and quickly bring the vessel to combat readiness. In this article, we will discuss in detail the technical nuances, assembly process and real opportunities that this budget-friendly but reliable service provides to the owner. PVC construction.
Many newcomers mistakenly believe that a cheap boat can not be of quality, but practice shows that when properly operated and maintained, even simple models last for years. load-limitNext, we will dive into the details that will help you make an informed decision about buying or improve your skills with an existing vessel.
Design features and materials
The basis of durability of any inflatable boat is the quality of the material used. turquoise 325 It's not just a film, it's a composite, where you have a polyester-stranded mesh between the PVC layers, which provides high tensile strength, and it's this technology that allows you to withstand contact with rocks, snags and sand without critical damage.
The joints are made by gluing on top, which is the standard for the budget segment. Although thermowelded seams are considered more durable, the quality of gluing at the right temperature is not inferior to them in reliability. Tightness It's made by using special adhesives that are resistant to water and temperature changes, and it's important to monitor the condition of the seams in the most tense places, especially after winter storage.
⚠️ Warning: Do not use water-based household adhesives or superglues for repair or glue valves – they will destroy the PVC structure and lead to irreversible damage to the material.
The design of the sides involves the presence of hinged bars around the perimeter, and this thickening not only protects the side from abrasion on the berth or the side of another boat, but also gives rigidity to the entire structure. flat-beltThe bottom is made of the same material as the side, but has a reinforced structure to resist the abrasive effects of the ground.
inflatable floor system (BBB)
The main feature of this model is the low-pressure inflatable floor. Unlike the solder boats, which require the assembly of a hard floor of laminated plywood or aluminum, it uses a single cylinder of complex shape, which greatly speeds up the preparation process for the launch and reduces the overall weight of the kit. inflatable floor creates an additional air cushion, increasing the unsinkability of the boat.
But it has its own nuances: the inflated bottom is less rigid than the plywood flooring, which can be felt when cruising inside the cockpit. stringer Or extra inflatable tubes, which are inserted into special pockets or fixed at the bottom, which give the bottom the necessary rigidity and form the right keeled profile, which improves driving performance.
Why is it important to properly pump the bottom?
If the bottom is not pumped to working pressure, it will bend under the weight of passengers, creating sailing and deteriorating handling, and sagging bottom wears out faster from friction against water and possible obstacles.
The bottom pumping process requires care. You need to use a pressure pump to keep up with the operating pressure specified in your passport. Pumped on a hot day, the bottom can burst due to air expansion, and the underpumped can deform. The optimal pressure is usually about 0.2 atm, but always check the labeling on the air. pump-valve.
In hot weather, pump the boat 10-15% less than the nominal pressure, as in the sun the air inside the cylinders will expand and the pressure will rise to normal.
Dimensions, capacity and load capacity
Model range turjus The cockpit has different modifications, but the 325 index indicates the total length of the product. The actual length of the inflated part may vary slightly depending on the pressure in the cylinders. The width of the cockpit allows two adults to comfortably fit, although the manufacturer often declares a capacity of up to three people. double-seater exploitation.
The load capacity is directly dependent on the volume of water to be displaced and the buoyancy of cylinders. data-sheet figures usually indicate the maximum permissible mass, which includes the weight of passengers, the engine, the equipment and the hull itself. Exceeding this parameter leads to a decrease in the height of the board above the water, which is dangerous in choppy conditions. Passenger capacity The average weight of a person is 75-80 kg, which should be considered when planning the crew.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 325 cm | Inflated condition |
| Full width | 145 cm | Depends on the pressure. |
| Diameter of the cylinder | 36 cm | Standard for class |
| Load capacity | 400-450 kg | Including boat weight |
| Weight of kit | ~28 kg | No motor or gear. |
Motor installation and driving performance
Despite the fact that turquoise 325 Often positioned as a propeller model, the transom design allows the outboard motor to be installed. The truncheon can be built-in (inflatable or rigid) or removable. The recommended engine usually does not exceed 3-5 horsepower. Installing a more powerful engine will create excess traction that will not withstand. sink-board and the aft of the cylinders.
When driven, an inflatable boat behaves differently than a hard-bottomed keel boat, and the absence of a deep keel and a V-shaped profile (to the fullest extent) causes the vessel to prowl harder and to hold its course worse in lateral waves. motorization It is very effective for moving to the fishing point.
It is important to center the engine properly. If the engine is too heavy to feed, the boat will catch the nose, which will worsen the visibility and stability. transom-angle Inflatable boats are often fixed or have a small range of adjustment, which requires the selection of optimal lower unit.
☑️ Check before exit on the motor
Assembly and preparation for operation
Building a boat with an inflatable floor takes less time than installing a plyol version, but requires a certain sequence, first unfolds and slightly inflates the bottom, then the board, avoids the formation of folds that can be rubbed. stringer and all compartments shall be fully pumped to the working pressure.
You should pay special attention to the valves. Before inserting the pump, make sure that they do not contain sand or fine dirt. depressurization After pumping, it is recommended to check the pressure with a pressure gauge, since it is difficult to determine the desired stiffness of cylinders by eye.
⚠️ Warning: Never leave a fully pumped boat in direct sunlight for long periods of time unattended - thermal expansion of air can cause the seams to rupture.
For storage in assembled but not deflated condition (if space permits), the boat is better kept in the shade. If you need a compact package, the deflation begins with the aft and bow cylinders, then releases air from the bottom. The folding should be careful, without sharp inflections in the same places, so as not to damage the reinforcing layer. PVC.
Care, storage and repair
Durability Turquoise 325 After each operation, especially in salt water or in contaminated water, the boat must be washed with fresh water and thoroughly dried, and wet packaging guarantees mold and unpleasant odors that are almost impossible to remove. Suit It should be carried out in the shade, since ultraviolet light is the main enemy of polymers.
In the off-season, it is better to store the product in straightened form or loosely rolled up in a large bag at room temperature. Sharp temperature changes and storage in the cold make the material brittle. If the boat is wintering in the garage, make sure that it does not get chemicals or fuels that can dissolve. plastic.
Small punctures are easily repaired with a repair kit that usually comes with a kit. The surface is degreased, a patch of the same material is applied and tightly pressed. For more serious damage, such as joints divergence, it is better to contact a specialized workshop that uses professional equipment for the purpose of cleaning the equipment. heat-welding Or a good glue.
Regular washing and proper storage in a dry place at temperatures above 0°C extend the life of the boat Birusa 325 twice.
Frequently Asked Questions (FAQ)
Is it possible to go to sea on a boat of Birus 325?
This model can only be used at sea in calm weather and in close proximity to the shore, the lack of a full-fledged keel and low sides make it vulnerable to sea waves, and for sea trips, it is recommended to choose specialized keel boats with higher sides and a hard bottom.
Which pump is best used for pumping?
The best choice would be a two-way foot pump ("frog") or a quality electric pump with a pressure limiter. Hand pears will require too much effort and time. It is important that the pump has adapters that are suitable for the type of valves your turquoise.
How long does the boat last for active operation?
With care, no extreme loads and proper storage, the service life can be 7-10 years or more. The main factor of wear is mechanical damage and exposure to ultraviolet light, so compliance with operating rules is critical for longevity. polymeric.
Do I need to register this boat with GIMS?
According to the current legislation of the Russian Federation, registration is required for boats weighing more than 200 kg (in running order) or with an engine power of more than 8 kW (about 10.8 hp). turquoise 325 It weighs significantly less than 200 kg and is equipped with an engine of up to 5 hp, it usually does not require registration, but laws may change, and the final decision should be clarified with the local branch of the GIMS.
