St. Petersburg, with its extensive network of rivers, canals and proximity to the Gulf of Finland, is rightfully considered one of the capitals of water tourism in Russia. For thousands of residents and guests of the city on the Neva River, the issue of purchasing a swimming aid is especially acute, because it is here. NDN (high pressure inflatable floor) have become the de facto standard for fishing and recreation, and unlike the classic plywood piola models, these designs allow the vessel to be assembled in a compact backpack, which is critical for metropolis residents who do not have a garage or trailer.
Market PVC boats The Northern capital is huge: from budget Chinese replicas to elite models of domestic production, adapted to the harsh conditions of Ladoga. The key advantage of buying in St. Petersburg is the possibility of a “live” inspectionBecause most of the major dealers have showrooms where you can evaluate the hardness of the bottom and the quality of the seams personally, many models are assembled in the Leningrad region, which guarantees the freshness of the material and the absence of long storage.
But the abundance of offers often puts the buyer at a dead end. solar, frigate or Hunter.? Should we overpay for PVC reinforced or should we save on transom? In this article, we will examine in detail the nuances of choosing, operating and storing inflatable boats with NDNDND in the conditions of the north-western region, where weather and water dictate their strict rules.
Design features and advantages of BND for Ladoga
The abbreviation NDND stands for “inflatable floor of low pressure”, but modern technologies have allowed to create a bottom. high-pressure High Pressure, which is as hard as aluminum sheet, is a lifeline for Lake Ladoga, which is known for its unpredictable wave, and a hard inflatable floor extinguishes shocks against waves much more effectively than a soft floor, ensuring stability even in a calm state, which is rare on Ladoga.
The most important element of the design is the keelson - an inflatable beam running along the bottom. Kieliness It allows the boat to keep its course better and to go out for planing with an outboard motor. In St. Petersburg, where you often have to overcome the jets of passing boats or barges, having a full keel and a hard bottom becomes a matter of safety, not just comfort.
Materials used in production also play a role: boats intended for use in St. Petersburg must be made of five-layer reinforced PVC density of at least 750 g/sq.m. Cold-resistant plasticizersThe stains added to the fabric prevent the material from cracking during autumn fishing, when the air temperature can drop below zero, and the water in the Neva remains icy.
⚠️ Warning: When buying a boat, be sure to check for overpressure vent valves. In the sun, even in the cloudy St. Petersburg summer, the air inside the cylinders heats up and expands, which without emergency valves can cause the seams to rupture.
Comparative table of popular types of bottom will help to determine the choice:
| Type of bottom | Structure weight | Assembly/Disassembly | Driving performance |
|---|---|---|---|
| BNDD (high pressure) | Medium/High | Fast (10-15 min) | Great, gleaming. |
| Pilled (plywood/aluminum) | Highly | Long (20-30 min) | Good, but sail. |
| Soft (inflatable) | Low. | Instant. | Low, just for quiet water. |
Popular brands and models in the market of St. Petersburg
St. Petersburg is not only a major consumer center, but also a production site for many well-known brands. frigate, hunter, Solar. and rivieraThese manufacturers have been honing technology for decades, building boats that are perfect for local conditions. Frigate M with reinforced transom is in stable demand among owners of powerful motors.
The budget segment is represented by Chinese-made models or Russian assemblies from imported components. It is important not to chase a low price, since savings are often achieved by using thinner PVC or lower-quality fittings. For regular trips to the Gulf of Finland, it is better to consider the models of the middle price range, where the model is used. two-piece This is a seam that ensures tightness for years.
When choosing a particular model, you should pay attention to the presence of additional options, which are often in the basic configuration of St. Petersburg manufacturers: these can be reinforced cylinder linings, shingles around the perimeter and convenient handles for carrying. transom wheels, although they are an accessory, in conditions of stony descents on the Karelian Isthmus become a necessity.
Why are local brands better than imported ones?
Local manufacturers (Fregat, Hunter, etc.) adapt their boats to the climate of the Northwest Federal District. They use frost-resistant glue and PVC, which does not smack at low temperatures, unlike many southern or purely Chinese counterparts, designed for a warm climate. In addition, it is much easier and faster to find spare parts or a camera for repairing a local brand in St. Petersburg.
Where to buy: an overview of shops and exhibitions in St. Petersburg
Buying a boat in St. Petersburg has its advantages, the main of which is the possibility of personal contact with the seller and inspection of the goods. Large specialized stores such as Boat-Peter, Vodkomotorika or Peter-Bot offer not just a showcase, but a full service.
Specialized exhibitions such as the Bot Show or the Neva Bot Show, which take place annually at Expoforum, hold special events that allow you to compare dozens of models from different manufacturers side by side, talk with plant engineers and get special exhibition discounts, and it is at exhibitions that often present new products that will be on sale in a few months.
When visiting the store, be sure to conduct a visual inspection: seams should be smooth, without glue bloating, valves - sit tightly in the nests. Feel free to ask the seller to inflate the boat (if space allows) or at least demonstrate the hardness of the bottom. Buying through online stores without the possibility of return is also possible, but carries the risk of obtaining a defective product that will have to be returned at your own expense.
- 🛶 Specialized salons: the ability to “feel” the goods, get a warranty and service.
- 🏭 Manufacturers: often have their own stores in production with prices below market prices.
- 📦 Marketplaces: wide selection and delivery, but high risks on return and lack of pre-sales preparation.
- 🤝 Billboards (Avito, etc.): the opportunity to buy used or new from hand cheaper, but without a guarantee.
Preparation for the season: complete sets and accessories
Buying the boat itself is only half the battle. To fully and safely operate on the waters of St. Petersburg and the Leningrad region, you need the right equipment. First of all, we are talking about the anchor system. For NDNDL weighing up to 200 kg, an anchor weighing 3-4 kg is enough, but on Ladoga, with its depths and wind, it is better to have a spare version or an anchor cat that is easier to hook by the stones.
The second important element is boat protection: Silicone cylinder coatings extend the life of the material, protecting it from ultraviolet light and dirt, and also remember the remix, which should include not only patches, but also special glue (for example, adhesives). Uranus or Radical), degreaser and roller, and it can be difficult to find these materials in the field.
Comfort on the water depends on the quality of the seats and the ability to install an awning. Many models of NDND allow you to install frame awnings, which saves from a sudden shower, which in St. Petersburg can begin at any minute. It is also worth considering buying a sealant for things, since even in the driest boat splashes are inevitable.
⚠️ Warning: Never use Moment or Superglue universal adhesives to repair PVC boats, they destroy the structure of the material. Use only specialized two-component polyurethane adhesives designed for PVC.
Operation and storage in the metropolis
Storing a NDND boat in an apartment is a challenge that many residents of St. Petersburg face. When deflated, the boat takes place comparable with a large tourist backpack, but drying before packaging is a prerequisite. If you leave the PVC wet, after a few months, mold can appear that is almost impossible to remove, or the process of “laying” of tissue begins.
Winter storage requires temperature control. Although modern materials are designed for frost, storing the assembled boat on an unglazed balcony is not recommended due to temperature changes and condensation. The ideal option is a dry room with a temperature of -10 to +25 degrees. Before long storage (winter) it is recommended to treat the seams with a special air conditioner for PVC.
Transportation of the boat in public transport or the subway is possible if it is packed in a case. However, it is worth considering the dimensions: a bag with a length of 110-120 cm can not pass into the turnstile or create inconveniences during rush hour. For car owners, the problem is solved easier, but there is a nuance: in the summer in the trunk of the car the temperature can reach + 60... + 70 degrees, which is dangerous for a fully pumped boat.
When packing a boat in winter, don’t fold it in the same folding places as in summer, which will prevent permanent cloth cloth cloth and prolong the life of the product.
Safety on the water: GIMS rules and common sense
For boats with an engine up to 8 hp (inclusive) and up to 7 meters in length, registration with GIMS and the availability of category A rights (for small craft) is not required if the vessel is used for personal purposes. However, this does not exempt the owner from observing the rules of navigation and the availability of the necessary equipment.
There must be life jackets, a scoop, a faline anchor and a lifeline on board. In the dark or in limited visibility (fog, rain), you must have a white light source visible from all sides, and neglecting these rules in the active navigation of the Neva can cost a life.
Particular care should be taken when entering the Gulf of Finland, where even with an apparent calm, a wave can quickly rise, and the current can carry the boat into the open sea. Life jacket The statistics of accidents on the water are relentless: most tragedies happen to those who "just went out for five minutes" without a vest.
Even if the law does not require registration of your boat, having a vest, anchor and a serviceable pump is a must for survival on the big water.
Frequently Asked Questions (FAQ)
Do I need to register a boat NDND in GIMS in St. Petersburg?
Registration is not required if the outboard motor is less than 8 hp (inclusive) and the length of the vessel is less than 7 meters, and it is used for non-commercial purposes.
What is the optimal pressure to pump to the bottom of the NDND?
For most models, the operating pressure is 0.2-0.25 atmospheres (about 200-250 mbar). You can't pump until you stop, which can cause the seams to rupture when heated in the sun. Use a pressure gauge for control.
Can I leave my boat in the sun?
Long exposure to direct sunlight is not recommended. PVC heats up, pressure inside rises, which creates a risk of strain or rupture of the seams. If there is no shelter, periodically blow a little air or cover the boat with a tent / fabric.
How long does a PVC boat serve when operating in St. Petersburg?
With proper care, storage and operation, high-quality PVC (density from 750 g / sq.m.) serves 10-15 years or more. The main enemies are ultraviolet radiation, improper storage (wet) and mechanical damage to stones.
What engine to choose for a boat NDND length of 320-360 cm?
For such sizes, the optimal motors with a capacity of 5-9.9 hp 5 hp will provide a confident exit to the planing with one angler and cargo. For two people and a full load, it is better to consider options 9.9 hp or electric motors with thrust from 50 lbs.
