Choosing a swimming aid for fishing or resting on the water often comes down to finding a balance between cost, reliability and comfort. It is in this segment that many aquatic motorists pay attention to the model. Stingray 390This is not just another Kazanka, but a thoughtful project that combines time-tested design solutions and modern requirements for water safety.
The series’ aluminium boat has long established itself as a workhorse for Russian water bodies, designed to withstand the wave characteristic of Ladoga, Onega and large reservoirs. Unlike inflatables, there is no risk of breaking through a snag cylinder, and the strength of the metal allows you to not stand on ceremony with berths and rocky bottoms.
However, as with any technique, Stingray 390 There are some features to consider before buying, and in this article we will discuss the design, possible upgrades and real-world experiences so that you can make an informed decision.
Body design and bottom geometry
The backbone of any boat is its hull, and in the case of the Model 390, engineers have been betting on the classic keel scheme. The bottom has a pronounced V-shaped shape in the bow, which smoothly transitions into flatter contours to the transom, which allows the vessel to confidently keep its course and not prowl in lateral turbulence, which is especially important in trolling.
The material used is aviation aluminum, which is highly corrosive. The thickness of the sheets varies: the bottom is usually made of thicker metal to protect against impact, and the sides can be thinner to reduce the total weight. Welds are made qualitatively, often using argon welding, which guarantees tightness for many years.
⚠️ Attention: When inspecting the used Stingray 390, pay special attention to the condition of the welding cans and transom fasteners. These are the areas that experience maximum twisting loads and can have hidden microcracks.
An important feature of the design is the presence of zygomatic stringers, which not only add rigidity to the body, but also serve as a spray thrower, improving visibility for the driver and passengers, and also protect the sides when moored against the concrete walls.
Technical specifications and load capacity
The 390 Stingray range typically means a body length of about 3.9 meters, the optimal size for transportation on the roof of a passenger car or on a small trailer, and the midsection width is usually about 1.5-1.6 meters, which provides sufficient stability to accommodate two or three people with a full set of equipment.
Load capacity is a critical parameter for anglers; the design allows you to safely carry up to 400-500 kg, including the weight of the engine, fuel, crew and cargo. Passport capacity is often limited to three to four people, but the actual usable area of the cockpit allows you to accommodate more gear than you might think.
The weight of the boat itself without the engine and equipment usually varies between 100-120 kg. This is quite a lot for manual carrying, so the presence of a trailer or keel cart with inflatable wheels is almost a prerequisite for comfortable operation.
| Parameter | Meaning | Note |
|---|---|---|
| Maximum length | 3.90 m | By hull roundabout |
| maximum width | 1.55 m m m | Midel-spangout. |
| Height of board | 0.65 m | Including the timber |
| Passport capacity | 3 people. | Up to 300kg |
| Max, engine power. | 30 hp | 15-20 hp is recommended. |
Ergonomics of the cockpit and layout
The interior of the boat Stingray 390 It's organized with a focus on functionality, and the absence of unnecessary bulkheads allows you to move freely around the cockpit, which is especially appreciated when catching large fish, and the floor is usually grooved, which prevents you from slipping even in wet shoes.
Seats (banks) are often removable or foldable, which allows you to transform the space for specific tasks: set up a tent, lay out sleeping bags for the night or place a large load. Some modifications can be equipped with a nose handle, which is a great solution for storing anchor and small things.
The attachments are standard, the oars, the liners and the sonar are designed in advance, but the installation of a full-fledged tent or a running awning transformer may require the reworking of the frame or the ordering of an individual solution for the dimensions of this particular model.
⚠️ Warning: Don't overload the bow of the boat. Shifting the center of gravity forward at a short hull length of 3.9 meters can lead to cockpit flooding and reduced handling.
Motor installation and driving performance
The transom plate on the Stingray 390 boat is designed to install outboard motors with a capacity of up to 30 horsepower, although the optimal range for comfortable planing with full load is 15-20 hp Two-stroke engines are preferred due to the lower weight, which is critical for boats of this size, where each kilogram affects the different.
When going out for planing, the boat behaves predictably, because of the keeliness of the nose, it does not goat on a small wave. However, it is worth remembering that the aluminum body is quite noisy. The knock of waves on the bottom and the engine can tire during long transitions, so the use of noise insulation or carpeting on the floor becomes necessary.
Secrets of fuel economy on planing
To reduce fuel consumption on a boat with a length of 3.9 meters, it is important to choose the right propeller. Too much stride will make the engine run in tension, too little will not allow you to enter the mode. Optimal rpm for cruising speed is 75-80% of the maximum. Also affects the cleanliness of the bottom: fouling with algae can increase consumption by up to 15%.
High speed control depends on the motor's pullout, and often the standard transom departure is not enough, and the motor has to be moved back by using a paddle or hydrofoil, which helps to lift the nose and improve visibility, and stabilize the stroke.
Tuning and improvement DIY
Buying the basic version of the boat is just the beginning. Stingray 390 They're going to upgrade sooner or later, and the first thing they do is they usually change their regular seats to more comfortable seats, with soft upholstery and adjustability, and they're also popular for putting soft linings on board for ease of fishing.
One of the most useful improvements is the installation of harundukes and storage boxes, which is important in a small boat that everything has its place, and the manufacture of sealed boxes under the bancami allows you to increase the usable volume and use them as additional buoyancy in an emergency.
- 🛡️ Installation of keel or zygomatic keels to improve course stability.
- 💡 Installation of LED cockpit illumination and navigation lights for safety in the dark.
- 🎣 Installation of holders for rods (outriggers) and a sounder table.
- 🔋 Organization of a box for battery with ventilation and reliable fastening.
And don't forget to protect. Aluminum is strong, but when you hit a rock, you can get dents at speed, you can put keel protection in rubber or an additional metal profile, and you can actually extend the life of the bottom, and you can also use film tape on the bottom of the sides or anti-gravel coatings.

Comparison with competitors and final conclusions
In the market for aluminum boats about 4 meters long, the Stingray 390 has direct competitors such as Crimea, Voronezh or more modern brands such as Salute and Metal Service. The main advantage of Stingray is often a more affordable price with comparable welding quality and metal thickness.
However, the basic versions can vary greatly from manufacturer to manufacturer, and you'll get a boat with a handkerchief and awning in the base, and a bare hull somewhere, so you'll need to look carefully at the final cost with the right equipment when you choose. A key factor in the selection of the Stingray 390 is its maintainability: a simple profile allows you to perform welding work in any workshop working with aluminum.
In conclusion, it can be said that the boat Stingray 390 It's a great choice for those looking for a reliable, unkillable fishing and recreation vessel for the weekends, and it's not without the disadvantages of the budget segment, but they are easily eliminated by competent tuning, it's an investment in safety and the pleasure of being on the water, which will last for decades with proper care.
The Stingray 390 is a “constructor” for an adult: by buying a base, you get a reliable platform that can be endlessly improved to suit your needs.
When buying a used boat, be sure to check the dates on life jackets and fire extinguisher if they come with a kit. Their expiration date may have long expired, which will require additional costs.
Frequently Asked Questions (FAQ)
Is it possible to go out on a Stingray 390 boat to the big water?
Access to large bodies of water (Ladoga, Onega, sea) is possible only in calm weather and with a full set of safety, navigation and communication. However, due to the short length (3.9 m) and the height of the board, being on such a boat in choppy conditions above 0.5 meters can be dangerous and uncomfortable.
Which trailer is better to choose for this boat?
The best solution is a single-axle trailer with pawns. Lodges are better than keel rollers, distribute the load on the body during long parking and transportation along the highway. Make sure that the trailer has a margin for carrying capacity (minimum 350-400 kg).
Do I need to register a boat with GIMS?
Under current Russian law, small craft weighing more than 200 kg (along with an engine) are subject to registration. If the weight of your Stingray 390 boat with an installed engine exceeds this threshold, registration and the availability of category M rights are mandatory.
How to keep a boat in winter?
Aluminum boats are best kept upside down under a canopy or indoors so that water and snow don't accumulate inside. If stored outside, be sure to cover the boat with a breathable awning to avoid condensation inside.
