Advantages and disadvantages of LGN-2U: an honest analysis

LGN-2. It's a market for decades after it was phased out, and here are the key benefits:

  • 💪 Strength and durability: With proper care, the body serves 20-30 years without major repairs.
  • 🔧 Repairability: aluminum case is easy to weld, and spare parts (banks, transoms) can be made independently.
  • 🚗 Transportability: weight 110 kg It allows you to transport a boat on the roof of a passenger car.
  • 💰 Low price in the secondary market: The b/w models are in good condition. 30-80,000 rubles. (2026).

However, there are also significant disadvantages that sellers often do not mention:

  • ⚓ Weak stability on the wave: flat bottom makes the boat a "roll" in the side wind or excitement from above 2 points.
  • 🔥 Risk of corrosion: When in contact with salt water or stored in a wet room, the metal is oxidized, especially in welding sites.
  • 🛠️ Inconvenient ergonomics: Standard cans (seats) are low, and the lack of steering requires improvements to the engine.
  • 📉 Low speed: even with a motor 10 hp boat rarely accelerates over 20–25 km/h.

A particularly critical disadvantage is Lack of certification by modern GIMS standardsBoats built before the 2000s did not pass mandatory certification, which can create problems when registering engines with power over the top. 5 hp.

LGN-2U registration in GIMS: step-by-step instructions for 2026

Since 2021, the rules for registration of small craft have been tightened, and LGN-2. falls under mandatory registration, if it is installed motor capacity 5 hp. The procedure includes the following steps:

  1. Preparation of documents:
    • Passport of the boat (if preserved factory).
    • Contract of sale (if you buy used).
    • Motor Passport (if installed).
    • Receipt for payment of the state duty (1,600 rubles. for registration).
  • Passage of technical examination: The boat is inspected for compliance with safety requirements (the presence of life jackets, fire extinguisher, buoyancy compartments).
  • Application to GIMS: via the portal Public services Or in person at the department.
  • Obtaining a boat's ticket: pass out 10 working days.

    • Features for LGN-2.:

    • 🔧 In the absence of a factory passport, you will have to restore documents through the manufacturer's archive (often impossible).
    • 🚫 Power-powered motors over 10 hp on LGN-2. Registered only after transaxialization (Act of improvement is required).

    The cost of a full package of documents (including examination and fees) will cost in the 5-8 thousand rubles.Without registration, operation of the engine over 5 hp fined up 2,000 rubles. (Article 11.8 of the Administrative Code of the Russian Federation).

    What if LGN-2U does not have documents?

    If the boat data sheet is lost, you can try to restore it through the archive of the Leningrad Shipyard (contacts: +7 (812) XXX-XX-XX). However, in practice, this is possible in less than 30% of cases. The alternative is to design the boat as a "home-made vessel" through the expert commission of GIMS, but this will require additional costs (from 10 thousand rubles) and time (up to 1 month).

    Repair and modernization of LGN-2U: from welding to tuning

    Over time, even the most reliable LGN-2. It needs repair. Let's look at the typical problems and how to fix them.

    Repair of the hull: welding and rivets

    • 🔥 Argon welding apparatus (for aluminum) or solder-burner.
    • 🛠️ The Rivetor and aluminium rivets (diameter 4-5 mm).
    • 🧴 Anti-corrosion primer (for example, Zincrometal).

    Step-by-step instructions for eliminating cracks:

    1. Clean the damaged area to pure metal (sandpaper or brush).
    2. With cracks up to 5cm enough soldering using flux for aluminum.
    3. For long cracks (more than 10cm) a thick sheet aluminium lining will be required 1.5–2 mm, welded along the contour.
    4. After welding, treat the seam with anticory and paint.

    2. Strengthening the transom under a powerful motor

    If you plan to install the engine 15-20 hp., standard transom LGN-2. You need to be stronger.

    • 🔧 Installation of the lining steel-thick 4-5 mm (Cutted on top of the standard transom).
    • 🛠️ Replacement of transom with new with the hardness of the stains, 5-10 thousand rubles.).
    • 📐 Trans lengthening (for the best propeller) - requires welding the body.

    After the completion, you will definitely get survey In GIMS, otherwise the engine is above 10 hp I can't register.

    Tuning for comfort: seats, steering, canopy

    Standard equipment LGN-2. Spartan, but it is easy to improve:

    • 🪑 Replacement of cans adjustable seats with shock absorbers (e.g. from Boats-2).
