In the world of compact fishing and hunting boats, models with low pressure inflatable bottoms, known as the “Low Pressure” are stand-alone. NDMAThis is the class of boat. Orca 325 NDLDThe squirrel is popular because of its reliability and versatility, and many aqueous motors are looking for this balance between light weight and water resistance, and this model from the Russian manufacturer Reef fully meets these expectations.
The main feature of this model is the design of the bottom, which is a single inflatable section, rather than a set of aluminum floorboards, which radically changes the way the vessel is operated and stored. inflatable floor provides excellent germination on the wave and increases the overall unsinkability of the structure, which is critical when entering large reservoirs.
The 325 centimeter size allows two adults to comfortably fit with the necessary equipment, and unlike the more simple ones, it uses modern materials and gluing technologies to ensure the longevity of the seams even in active use in salt water or at low temperatures.
⚠️ Attention: Despite the material's high strength, the inflatable floor of NDNDM requires careful handling when launched. Avoid sharp stones and shells that can damage PVC, unlike aluminum floorboards, which are more resistant to mechanical damage.
Design features and materials
The basis of durability of any inflatable boat is the material from which it is made. Orca 325 five-layer reinforced PVC It is a material with a density of 750 g/sq.m. or 850 g/sq.m., depending on the configuration, which is highly resistant to ultraviolet radiation, fuels, lubricants and temperature changes, and seams are usually made by hot gluing, which guarantees their tightness and tensile strength.
A key element of the design is the high-pressure inflatable floor (up to 0.2-0.25 atm), which is formed using a stringer system. longitudinal power-bandThis allows the boat to keep its shape even when the air temperature changes, preventing the material from sagging or overvoltaging.
The cylinders are separated into independent compartments, which is a mandatory safety requirement, and in the event of a puncture of one of the cylinders, the second one will ensure sufficient buoyancy to return to shore. sink-board, which in this model is reinforced and protected by rubber linings or a special profile to protect against engine shocks.
- 🛡️ PVC reinforced High density provides protection from punctures and abrasion.
- 🌊 The NDLD system gives the boat excellent seaworthiness and rigidity of the hull.
- 🔒 Independent compartments Ensure the safety of the crew in emergency situations.
It's important to note the quality of the fittings. The pump valves are made of brass or a durable plastic with a return valve, which eliminates the air effluent when you change the pump. All the handles for carrying are sewn to the power belts, not just to the cylinder, which allows you to safely transport the boat even with an outboard motor.
Dimensions and weight specifications
When choosing a boat, its weight and dimensions in packaged form are often the decisive factor. Orca 325 NDLD The full weight of the bags kit is usually no more than 35-38 kg, which allows it to be carried in the trunk of a passenger car or even on public transport (if the rules are met).
The 3.25-meter long is the middle ground, and the boat is no longer as sensitive to wave as the two-seater two-hundreds, but it is still quite maneuverable, with a cockpit width of about 110-120 cm, which provides enough space to accommodate two full-length fishermen or three in cramped conditions.
The interior space is optimized by displacement of the cylinders, which gives you a gain in the usable area of the cockpit. Load capacity The model allows you to carry on board up to 400-450 kg of payload, including the weight of passengers, engine, fuel and equipment, but it is worth remembering that the maximum load on the bottom is limited by the design of the NDNDT.
| Parameter | Meaning | Note |
|---|---|---|
| Full length | 325 cm | Including inflatable parts |
| Full width | 144 cm | Outwardly. |
| Cockpit length | 205 cm | Work area |
| Cockpit width | 114 cm | Distance between cylinders |
| Boat weight (without motor) | 36 kg | Average value |
Features of the exploitation of the sex of the NDND
The inflatable floor boat has its own nuances that distinguish it from the classic plywood piola models, and the main advantage is that there are no hard elements inside the hull, which makes grounding less dangerous for the structure.
To pump the bottom and cylinders, a high pressure pump is required. Conventional "frogs" are not suitable here, since you need to create a pressure of 0.2-0.25 atmospheres. Pumps with gauge mandatory, since pumping in the heat can lead to rupture of seams, and non-pumping - to deformation of the body and deterioration of driving qualities.
☑️ Preparing the boat for the season
Once used, the boat must be thoroughly washed and dried. Sand caught between the PVC layers on the bottom works like an abrasive. When assembled wet, this can lead to microcracks. Pay special attention to cleanliness. cross-plate And the stringer attachments.
⚠️ Attention: Never leave a pumped boat in direct sunlight for a long time unattended, the air pressure inside rises when heated and may exceed the permissible limits, which will lead to deformation of the seams.
For ease of movement inside the cockpit, you often use special mats or slats that are laid on top of the inflated bottom, which protects PVC from abrasion by the soles of your shoes and hooks of gear, and also improves thermal insulation if you plan to fish in cold water.
Compatibility with motors and speed
Model Orca 325 It is positioned as a lightweight pleasure boat or fishing boat, so the power requirements are moderate here. The recommended power of the outboard motor is from 2 to 5 hp. Installation of a more powerful unit does not make sense due to limitations on the load capacity and length of the hull.
With a 3.5-4 hp engine, the boat can reach speeds of up to 15-18 km / h with one passenger. When fully loaded, the speed drops, but planing is usually maintained. outboard Weight: An overly heavy motor on a short transom can lead to differentiation on the stern and reduced driving efficiency.
Optimum engine for Orc 325
The 3.5 hp lightweight two-stroke motors are ideal for this boat, weighing around 13-15 kg, making it easy to drive the boat alone. The four-stroke counterparts will be heavier, but will provide less fuel consumption and quiet operation.
The slingboard is reinforced and allows you to fasten the motors with a short leg (S). When installing the motor, watch the angle of inclination of the lower unit. transom-angle It allows you to get the boat to plane with minimal power, and you should also use an anti-cavitation stove to protect the propeller.
- 🚤 Motors 2-3 hp It will provide a quiet movement of up to 10 km / h.
- ⚡ Motors 4-5 hp. They take the boat out to plane with one person.
- ⛔ Motors over 6 hp. Not recommended because of the risk of transom damage.
Package and additional accessories
Standard equipment of the boat Orca 325 NDLD Usually includes the boat itself, the bag for packaging, remix and passport, but for comfortable operation owners often buy additional accessories, among them the most popular anchor systems and comfortable seats.
The seats in the base version can be simple inflatable or rigid on brackets. Hard seats are more convenient for long fishing, but they add weight. Inflatable can seats are lighter and more compact, they can be used as a way of life. life-saving in an emergency.
To protect the bottom of the boat from abrasion and improve comfort, buy a special protective mat made of foamed PVC. It will also hide possible scuffs and prolong the life of the inflatable floor.
It is not superfluous to purchase a storage and transportation case. The native bag is often cramped, especially if you plan to bring an anchor, life jackets and a pump. A separate sealant for documents and telephones is a must-have element of equipment on the water.
| Accessory | Appointment | Recommendation |
|---|---|---|
| Cat anchor | Fixing in flow | Weight of 1.5-2 kg |
| Life jacket | Security | I'll be sure to go. |
| Double-acting pump | Pumping. | With a gauge. |
| germ-o-o-o-o- | Protecting things | Volume of 10-20 l |
Care, storage and winter conservation
Durability of the boat Orca 325 PVC material does not like prolonged exposure to direct sunlight and extremely low temperatures inflated condition. After each fishing, it is advisable to rinse the boat with fresh water, especially if you have been swimming in salt water or standing on a sluggish bottom.
Folding the boat freely, without tightening the belts on the bag, to avoid the formation of cracks on the folds. Periodically, once a season, the seams and valves should be checked for leaks with soap solution.
Proper storage of the boat in a straightened or half-blown form in a warm room significantly prolongs the service life of PVC materials and preserves the elasticity of the seams.
In winter, the boat is best kept at room temperature. If this is not possible and the boat stays in the garage where the temperature drops below zero, make sure it is completely dry. Moisture frozen in the folds can damage the reinforcement layer. It is also not recommended to keep the boat near the heating appliances.
⚠️ Attention: Do not use aggressive solvents, gasoline or acetone to clean the boat. They can dissolve PVC and damage adhesive seams. Use only special PVC cleaners or soap solution.
Regular inspection of the transom plate for plywood layering is also a must, and if the varnish or paint on the transmolina is damaged, it must be restored to prevent moisture from entering the wood, especially for boats that are often used with powerful motors.
FAQ: Frequently asked questions
Can I use Orca 325 for fishing in winter?
You can use a PVC boat at low temperatures, but with caution. The material in the cold becomes tougher and more vulnerable to impacts. You need to use special frost-resistant greases for the valves and avoid sudden movements during assembly.
Which pump is better for pumping NDND?
A low-pressure inflatable floor requires a pump capable of delivering pressures up to 0.25 atm (250 mbar), best suited to the foot pumps "toptun" with a gauge or electric pumps with a stop function tuned to low pressure.
How many people can comfortably fit in Boat 325?
Passport capacity is usually 2-3 people, it is comfortable to fish together with a full set of gear, three people will accommodate, but the free space will be minimal, which can affect safety and stability.
Do I need to register Orca 325 in the GIMS?
According to the current legislation of the Russian Federation, boats weighing more than 200 kg (including a motor) or with an engine powering more than 8 hp (for some categories) are subject to registration. Orca 325 The light engine is often included in the 200 kg limit, it may not require registration, but this issue should be clarified in the local branch of the GIMS, as the rules may change.
