The search for a reliable and spacious boat for family holidays or fishing often leads a potential buyer to consider models made of aluminum-magnesium alloy. The throttle Nelma 37 The new model is one of the flagship projects of the Siberian shipbuilding company Russian Boat, which combines years-old design and modern ergonomic solutions, designed to meet the harsh operating conditions on the rivers and reservoirs of Siberia, which automatically makes it highly resistant to mechanical damage.
The main feature of the project is its modularity and the ability to choose different layouts depending on the needs of the owner. Nelma 37 It can be equipped with simple hazel-bearing seats for fishermen, as well as a comfortable interior with a windshield and soft sofas, the high side and wide nose provide excellent stability even in severe excitement, allowing you to feel confident on the water in all weather.
In this article, we will discuss the specifications, design features, and conduct an honest analysis of the advantages and disadvantages of this popular model, you will learn about the real speed and fuel consumption figures, the nuances of transportation on the trailer and the features of operation in the winter to make an informed decision about the purchase.
Structural features and materials of the body
The basis of durability of this vessel is the use of aviation aluminum-magnesium alloy AMg5M. This material has high corrosion resistance, which is critical for operation in salt water or aggressive river environment. Body thickness It is 4 mm, and the sides and decks are 3 mm, which provides a margin of safety, allowing you to safely moor to unequipped shores or pass through shallow water with a rocky bottom without the risk of a hole.
The body is designed in a monodredout pattern with a heavily pointed nose and a pronounced keel. boat Nelma 37 Keeping the course steady and cutting the wave easily, ensuring a soft ride even at high speed, an important safety feature is the presence of sealed compartments of unsinkability located in the bow, stern and sides, which allows the boat to stay afloat even when fully filled with water.
When buying, pay attention to the quality of welded seams - they should be even, without pores and inflows, since the tightness of the body for many years depends on them.
Special attention should be paid to the bottom reinforcement system, which is that in the most heavily loaded places where stringers are usually located, additional longitudinal and transom profiles are welded, which prevents the appearance of "cottons" when hitting the water and reduces the level of vibration transmitted to the body. Unlike many competitors, the Nelma 37 has an all-welded body without the use of rivets in the underwater part.This eliminates the risk of leakage during active operation.
What is an AMg5M alloy?
It is a deformable aluminum-magnesium alloy that is not hardened by heat treatment, and its key advantages are high plasticity, excellent weldability and resistance to corrosion in seawater, making it an ideal material for shipbuilding.
Technical specifications and modifications
The manufacturer's range offers customers flexibility in the choice of configuration, which allows you to adapt the vessel to specific tasks. The basic version is often called "Nelma-37 Compact" or simply "Fisherman", and the more comfortable - "Nelma-37 Luxury" or "Cruise". Overall dimensions remain unchanged: length is 5650 mm, width - 2100 mm, and the height of the board on the midfield reaches 700 mm.
The passenger capacity and load capacity are some of the strongest features of this model, with a certified vessel for up to 6 people and a maximum load capacity of 600 kg, which allows for an impressive supply of equipment, fuel and equipment for multi-day expeditions. Passenger capacity It is confirmed by the relevant certificates, which is important for official registration in GIMS.
Consider the main differences in the modifications in more detail. The Compact version is focused on functionality and minimalism, offering open hazelnut seats and no windshield, which reduces sailing and weight. The Lux version features a full-fledged cockpit with soft seats, a windscreen with a gate, an awning on a metal frame and often has additional hazelnuts for storing things.
Performance and running tests
Driving performance Nelma 37 directly depend on the installed power plant. The manufacturer recommends the use of outboard motors with a capacity of 40 to 60 hp When installing a 50 hp engine, the boat goes on plane with two passengers at a speed of about 25-28 km / h. The maximum speed with one driver and a 60 hp engine can reach 55-60 km / h, but the cruising speed for an economical course is 35-40 km / h.
High speed handling is rated as excellent by owners due to deep scaling. The boat is not prone to yaw and confidently passes turns without dangerous roll. However, it is worth considering that at full load (6 people + cargo) to go to the sleeve, you may need a motor of at least 50-60 hp, otherwise the boat will go in displacement mode, significantly increasing fuel consumption.
The optimal power of the motor for full loading and confident planing is 50-60 hp, which provides a balance between speed and economy.
Fuel consumption is an important economic factor: when driving on a plane with a 50 hp engine and an average load, gasoline consumption is approximately 18-22 liters per hour. When switching to an economical mode and reducing speeds to 3000-3500 rpm, consumption drops to 10-12 liters, which allows you to travel long distances without frequent refueling.
⚠️ Attention: Do not exceed the recommended maximum power of the engine, specified in the boat's passport. Installation of too powerful engine (more than 70-80 hp) can lead to lifting of the bow, loss of course stability and a critical increase in the load on the transom, which is fraught with structural destruction.
Comfort and internal layout
Interior space Nelma 37 is designed with ergonomics in mind. The Luxury version has two soft sofas on the sides that can transform into sleeping places. Between them is a central passageway, and in the bow part is often organized a runduk table, which allows a company of 4-5 people to comfortably accommodate, facing each other.
For anglers, seating is possible on rotating platforms; wide knuckles are not only seats, but also storage for gear, anchor equipment and personal belongings; the deck floor is designed with anti-slip surfaces, which is especially important in wet weather or when fishing, when scales and mucus can appear on the floor.
The windscreen in the Luxury configuration has a complex shape, providing good visibility and protection from oncoming air flow and splashes. The glass design provides a gate for passage to the bow, where an anchor liner or additional equipment is often installed. The awning on the metal frame reliably protects against the scorching sun and sudden rain.
☑️ Check before buying a used boat
Transport and storage
One of the key issues for owners is transportation. Dimensions Nelma 37 (5.65 m long) allows the boat to be carried on a standard trailer of category "E" (if the total mass exceeds 750 kg) or even "B" depending on the total weight of the train. However, due to the width of 2.1 meters, the boat is outsized, which requires the installation of additional mirrors and compliance with the rules for the carriage of large goods.
The weight of the boat with the engine, fuel and equipment can exceed 500 kg. Therefore, the use of a reliable two-axle trailer with inertia brake is a prerequisite for safe operation. The trailer must be equipped with a padding that repeats the contours of the hull to avoid point loads on aluminum during prolonged parking.
Keeping a boat in winter requires no special conditions due to the frost resistance of materials. Aluminum does not lose its properties at low temperatures, and high-quality paint coatings and corrosion treatment protect the hull. However, it is recommended to keep the vessel under a canopy or cover it with a breathable awning to avoid accumulation of condensation and dirt inside the cockpit.

Owner reviews and final conclusions
Analysis of reviews of real owners Nelma 37 The picture is mostly positive, with users appreciating the hull's "unkillability," the ability to pass rolls and go ashore, and many people point out that the boat behaves predictably even in strong side winds, which is rare for lightweight aluminum boats.
Among the disadvantages most often mentioned are the sailing of high sides in a squally wind in the parking lot and the need for a powerful tractor to transport the full version with the engine. Some users also note a hard drive at low speed in the oncoming wave, if the boat is not loaded, but this is the price for high stability and seaworthiness.
Typical problems in operation
The main complaints concern the quality of the fittings (locks of runduks, loops), which sometimes have to be changed to more reliable, and the need for additional noise insulation of the engine compartment when installing powerful four-stroke engines.
In summary, it can be said that elma motorboat 37 It is a great choice for those looking for a versatile vessel for large bodies of water, fishing and family holidays, requiring a more powerful tow and motor than light PVC boats, but in return gives an unparalleled sense of safety, comfort and freedom of movement on the water.
⚠️ Attention: Before the first outing, be sure to check the tightening of all bolt joints, especially the fastening of the transom and cans. After the first 10 hours of operation, it is recommended to re-stretching the threaded joints, since aluminum has the property of giving a micro-shrinkage under load.
Frequently Asked Questions (FAQ)
Do I need to register Nelma 37 in GIMS?
Yes, the boat is subject to mandatory registration. The hull length exceeds 3 meters, and the power of the recommended engine (40-60 hp) is much more than 8 hp (or 5 kW). In addition, the weight of the equipped vessel with the engine also exceeds the permissible 200 kg, which makes registration unavoidable under the legislation of the Russian Federation.
Which motor is better to choose: two-stroke or four-stroke?
For Nelma 37 Both options are right to life. two-stroke engines are lighter, which is important when transporting, and cheaper to maintain. four-stroke quieter, more economical and more environmentally friendly, but heavier. Given the boat's load capacity, a four-stroke engine with a capacity of 50-60 hp will be an excellent choice for a comfortable family holiday, while a two-stroke one will suit avid fishermen who appreciate lightness.
Can I leave the boat on the water for the whole season?
Aluminum-magnesium alloy AMG5M is resistant to corrosion, but prolonged exposure to water, especially salty or contaminated, can lead to fouling and local damage to the paint coating. It is recommended to remove the boat from the water after each operation or use special anti-fouling coatings designed for aluminum.
Does Nelm have a 37-spoken cockpit?
The cockpit is not fully self-draining in the classic marine sense (when water flows away by rolling), but the design of the floor and the presence of scuppers allow you to effectively remove the water that has fallen by pumping or scooping, and the high side minimizes the risk of overflow.
