The Neman 2 boats, the technical characteristics of which are significantly improved compared to the first series, are compact, lightweight vessels with a pleasant appearance. The modification has a good carrying capacity, stability. It is convenient to operate. If desired, it can be launched into the water on its own.
The boat is easy to plan, has a well-developed architectural design. In its manufacture, an alloy resistant to corrosion is used, which makes it possible to operate it in salt water and store it in the open. The vessel is rationally thought out inside, spacious, has a lot of space for transporting passengers and cargo.
Destination
The updated Neman motor boat was conceived as a universal four-seater recreational fishing project with compact dimensions, more technologically advanced, with high performance characteristics. The development was carried out taking into account not very successful samples (Serebryanka, Amber, Neman 1). It was assumed that the vessel in question would be able to plan with the economical Veterok engine, while possessing less weight and contours than traditional four-meter ones.
The technical parameters and design of the updated version are almost the same as those of larger boats. It is worth noting that the release of the new version is carried out on existing conveyor lines using the technological base used in the manufacture of the Neman predecessor. For the most part, the designer's idea was successfully realized.
Short boat description
The ship has a traditional architectural design. It is equipped with an open cockpit and a niche under the engine. On the deck in the bow there is a panoramic glass “forehead”. The difference between the exterior of the Neman 2 is the installation of a high fence.
This design feature made it possible to expand the utility of the cockpit. The safety of the model increased due to the actual increase in the height of the sides to 750 millimeters with giving the exterior an original modern shape. Motor boats and boats Kazanka-5, Dnipro, Ladoga, Crimea, which are significantly larger than the sample in question, only slightly exceed its size in the cockpit, which has dimensions 1.8 x 1.25 meters.
Interior fittings
When reviewing the boat "Neman 2", the technical characteristics of which are significantly optimized, it is worth paying attention to its internal equipment. Passengers are transported on two transverse rigid cans of stamped metal. The feed element is also a cover for the locker. Cargo, tools and other equipment can be transported in a special niche under the can and deck on the bow. In addition, several recesses are provided for storing various useful little things and facilitating maintenance of the power unit.
The motor boat “Neman 2” is equipped with a wooden trellised floor. Floating blocks, which are fixed under the bow of the deck and in the area of the submotor compartment, serve as stabilizers and protection against flooding. They are made of foam. The vessel is equipped with oars, tench, scoop, nasal eye and mooring ducks.
Housing
This element is made of corrosion-resistant aluminum-magnesium alloy, which has excellent ductility and strength parameters. The hull of the boat "Neman 2", the technical characteristics of which are presented below, is equipped with sharp-edged contours. In the midship, the pitching index is 16 degrees, on the transom - 8 °.
Longitudinal type redans replace cutting ribs that resist transverse flow dispersion. Side boules are absent, which further increases the width of the hull at the stern. To strengthen the transom and the buoyancy of the stern, a 50-mm ledge is made by stamping at the niche level under the motor.
Domestic motor boat "Neman 2" has another feature. It is connected with the division of the case into separate segments, which are assembled in special boxes. This allowed the use of resistance welding during installation of the structure, and arc processing with rigid fastening of the sheets of the kit. Such an approach made it possible to reduce the deformations arising during welding and to obtain an excellent presentation.
Short review of the boat "Neman 2": technical characteristics
An important advantage of the vessel in question is its good stability and resistance to water. With a certain reduction in load, the boat can be operated with the economical Veterk-12. During testing, a speed of 27 kilometers per hour was developed (load - 170 kg).
The following are the main technical parameters of a motor boat:
- Maximum width and length (mm) - 1400/3800.
- Side height at midship (mm) - 750.
- Curb Weight (kg) - 130.
- Seating capacity (people) - 4.
- Capacity indicator (t) - 0.3.
- The maximum power of the power unit (hp) is 26.5.
- High-speed mode with the motor "Neptune-23" (minimum / maximum load) - 43.3 / 38 km / h.
When the waves are up to half a meter, the ship is subjected to moderate shock loads and can glide without reducing speed. In this regard, the maximum height wave during operation of the Neman 2 increased to 0.5 m (twice as much as that of its predecessor).
Completion
Testing of the Neman 2 vessel was repeatedly carried out, where other experimental and serial motor boats and boats participated. Participating in the race (1978), the vessel in question became the leader in the races of categories T-350 and T-500. According to the total count of performances in several disciplines, the crew with the Neptune-23 engine took the honorable second place, and the team with the Whirlwind-25 held the third position.
Owner reviews further confirm the versatility and practicality of the Neman 2 boat. It is suitable for both walking and fishing. Many users note good indicators of the strength of the case, dynamic characteristics and decent capacity. Judging by the reviews, it is advantageous to use a boat for winter fishing. The boat can be easily pulled out by two together on strong ice, and if it does not stand up, the fisherman can simply lie on board - his legs will be dry.
