The choice of a first or new vessel always involves a long study of the market and weighing all the pros and cons. In the small craft segment, a special niche is occupied by plastic boats, which confidently displace traditional metal counterparts due to their performance properties. plastic boat sprintIt has proven itself as a reliable and practical option for fishing and relaxing on the water.
Unlike aluminum, fiberglass is not corrosive, making it much easier to care for the boat in the off-season, and you don't have to worry about the bottom rotting from constant contact with water or salt. sprint It has excellent repairability in the field, if you know the technology of working with polyester resins.
In this article, we will analyze in detail the design features of this model, consider its behavior on the wave and give practical recommendations for modernization. A unique feature of the series is a reinforced trans-component unit designed for motors up to 50 hp without additional alterations.This makes the boat a versatile platform for both quiet trolling and high-speed planing.
Structural features and materials of the body
The basis of reliability of any vessel is its hull, made of composite materials. Plastic boat Sprint It is made by contact molding, which allows you to create complex contours that ensure excellent seaworthiness. The thickness of the side and bottom varies depending on the modification, but the standard value is considered to be 5-6 mm, which ensures high impact resistance.
An important element of the design is built-in buoyancy, and unlike inflatable tubes, which can be damaged, it uses polystyrene foam blocks enclosed in sealed compartments, and even when fully filled with water, the boat will remain afloat, which is critical to the safety of the crew.
- 🚤 The reinforced keelson runs along the entire bottom, increasing the longitudinal rigidity of the structure.
- 🛡️ The gelcoat coating protects the body from fading and small scratches when mooring.
- ⚓ The presence of a timber around the perimeter allows you to safely moor to the concrete walls.
The boat's trawler is made of multi-layered plywood protected by fiberglass or solid composite, and this place is under maximum engine load, so the quality of its execution is given special attention. When buying, be sure to check for chips and cracks in the area of the lower unit fastening.
Production technology
It's based on a matrix where the glass cans are layered and they're soaked in polyester resin, and after polymerization, you get a monolithic structure that doesn't require welding or riveting, so you don't see any leaks in the seams.
Performance specifications in water
The behavior of the boat on the water directly depends on the shape of its bottom. sprint It's usually equipped with a V-shaped bottom with a variable angle of keel, which allows you to confidently cut the wave. At low speeds, the boat behaves steadily, and when you get on plane, it becomes more predictable and soft in the course.
It's important to consider that the plastic case is heavier than an aluminum case of similar size, which affects acceleration dynamics, especially if you use the motor at the recommended power limit, but this weight is offset by better inertia and less swing in the parking lot.
The boat's handling depends largely on proper weighting, and if you move the cargo closer to the nose, the boat will start pecking at the nose, which is dangerous on the wave. categorically not recommended.
⚠️ Note: When operating in shallow water, remember that the plastic bottom, although strong, does not like to hit rocks at high speed. Try to pass such areas with minimal gas.
Comparison with aluminum analogues
The eternal debate between the plastic and metal proponents is not going away, to understand why. plastic boat sprint Aluminum is easier to transport on the roof of a car, but it is noisier and colder to use.
Plastics, on the other hand, have great heat and noise insulation properties, and you can fish in the early morning without fear of the bottom becoming icy, or talk to a friend without raising your voice because of the noise of wind and water, and it's often easier to repair a hole in plastic than to brew aluminum.
| Parameter | Plastic (Sprint) | aluminum |
|---|---|---|
| Body weight | Highly | Low. |
| Noise insulation | Great. | Low. |
| Puncture repairs | Medium complexity | High complexity |
| Term of service | 20+ years | 15-20 years |
Plastic allows you to introduce any shape and color, whereas aluminum is limited by the flexibility of sheet metal. For those who value comfort and appearance, the choice is often in favor of composite.
Motorization and installation of equipment
Selection of engine sprint It depends on your goals. For a quiet fishing, a 9.9 hp engine is enough to take a boat with two passengers to the plane. If you plan a full-load water trip, you should consider options with a power of 15-20 hp.
Installation of attachments requires care. When drilling holes in the sides for anchor ducks or fishing rod holders, be sure to use a sealant and special gaskets. Water trapped inside the fiberglass structure can lead to stratification when freezing.
☑️ Installation of the engine
The electrical wiring should be done with a marine cable with insulation that is resistant to ultraviolet and salt water. All connections are best soldered and insulated with adhesive heat shrinkage. Don't skimp on the quality of the electrician, because it is the key to safe operation.
Tuning and improvement DIY
Many owners don't stop at the factory and are looking to improve their boat. extension-rod or reworking the crank under the control of the "leg", which allows you to control the motor, sitting in the depths of the cockpit.
Storage systems are also frequently upgraded, and the installation of sealed hazelnuts in the bow allows you to keep things dry even in a violent storm, and the interior surface of the board can be coated with soft material so that you don't scratch against the hard plastic when you move.
To improve performance, you can install a hydrofoil on the transom, which will reduce yaw and make it easier to glid, especially with one engine.
Keep in mind the lighting. Installation of running lights that comply with the rules of the PPF is mandatory for night swimming. A simple LED tape around the perimeter of the cockpit will create a cozy atmosphere for evening fishing.
Care, storage and winter conservation
Despite the strength of the material, plastic boat sprint After each foray into the water, it is advisable to rinse the body with fresh water, especially if you have been swimming on the sea, the salt cries and can damage the gelcoat over time.
At the end of the season, the boat must be preserved, washed, dried and polymerized to protect against UV light, and the best way to keep the vessel is indoors or under a safe awning, avoiding direct sunlight that can cause fading.
⚠️ Warning: Never leave the boat on the water for long periods unnecessarily, and shell and algae exposure significantly impairs performance and increases fuel consumption.
Regularly check the condition of fasteners and fittings. Vibration at the engine can unwind even well-tightened bolts. Preventive inspection before each season will prolong the life of your swimmer.
Proper preservation and storage in winter increase the life of a plastic boat by 30-40%, maintaining its presentation and technical specifications.
Frequently Asked Questions (FAQ)
What is the maximum weight a Sprint boat can bear?
The load capacity depends on the model and length of the hull, and typically for boats 4-5 meters long, the rated carrying capacity is between 400 and 600 kg, including the weight of people, motor and equipment, and it is life-threatening to exceed this limit.
Can I repair a plastic boat by myself?
Yes, small cracks and chips can be repaired with a remix consisting of epoxy resin and fiberglass. Deep holes require a more serious approach, perhaps with the involvement of specialists.
Do I need to register a Sprint boat with GIMS?
Registration is required for vessels weighing more than 200 kg or with an engine powering more than 8 kW (about 10.8 hp). If your boat is lighter and the engine is weaker, registration is not required, but it is advisable to have documents for the vessel and the engine with you.
How does the boat behave in the side wind?
Due to the V-shaped bottom and a certain weight, the Sprint boat is quite stable, however, with strong side winds and high sailing (for example, with an awning), it may be necessary to adjust the course or reduce speed.
