The modern small boat market offers a wide range of watercraft, but inflatable boats made of polyvinyl chloride occupy a leading position due to the combination of mobility, reliability and affordable cost. Among domestic manufacturers, the Compass brand has established itself as a supplier of quality products adapted to the difficult climatic conditions and requirements of water tourism enthusiasts. Choosing the right model often becomes a difficult task, requiring an understanding of the technical nuances and specifics of operation in various water bodies.
In this article, we will discuss in detail the design features, advantages of materials and the model range to help you make an informed decision. PVC reinforcedThe tyre used in manufacturing is significantly different from conventional rubber or simple polyethylene, providing high tensile strength and UV resistance, and understanding these differences is critical to the longevity of your vessel.
Special attention should be paid to the correct selection of the size and type of bottom, because these parameters determine the performance and stability on the wave. Many beginners make the mistake of buying a boat too small with a powerful engine, which leads to inefficient fuel consumption and discomfort. We will consider how to avoid typical errors in configuration and operation.
Advantages of Materials and Production Technology
The basis of any high-quality boat is the hull material. In the case of products, the Compass uses a five-layered hull. reinforced PVCIt's a complex structure of synthetic filaments embedded between layers of polyvinyl chloride, and it offers exceptional tensile strength and puncture, which is especially true when you're out on rocky shores or shallow water with a shell.
The hot air welding technology creates a monolithic bond that is as strong as the material itself. Unlike adhesives that can dry out over time or under the influence of aggressive chemistry, the weld remains sealed throughout the life of the product, which is especially important for models designed for use in salt water or in extreme north conditions.
In addition, the material has a high resistance to fuel, gasoline and oil, which allows you to safely place fuel tanks inside the cockpit. Tissue density It varies depending on the model, but even the basic versions have indicators that allow you to withstand significant mechanical stress without deformation.
⚠️ Warning: Despite the high strength of PVC, avoid contact with fire sparks or smoldering coals, as the material is not fireproof and can get through damage.
Technical specifications of the material
The five-layer structure includes two outer protective layers, two layers of reinforcing mesh and a central layer that ensures tightness. The density of the fabric ranges from 750 to 1100 g / m2, depending on the series.
Overview of the model range: from compact to expeditionary
The manufacturer’s range of models covers a wide range of needs, ranging from compact two-seater options for quiet fishing to serious boats for sea trips. Each series has its own unique features aimed at solving specific user tasks. Load capacity Passenger capacity is a key consideration when choosing.
The 290 series is a classic solution for single or one-and-a-half operation, lightweight models that are easy to transport in the trunk of a passenger car, ideal for fishing in small lakes where you don't need to overcome a strong wave, but they may not be large enough to go out into the open water for a comfortable stay.
Larger models, such as the 320 and 380, are already in the category of full-fledged family boats. outboardThis is a very powerful way to plane fast, and these models often use high pressure inflatable bottoms (HPDBs), which improve seaworthiness.
- 🚣♂️ Compact models up to 2.9 meters long are ideal for fishing alone and transportation in a small car.
- ⚓ The middle class (3.0-3.4 meters) provides a balance between mobility and capacity for two anglers.
- 🌊 Expedition models with a length of 3.6 meters are designed for long hikes and swimming in strong winds.
Underbody design: slate, plywood or NDND?
The bottom type is perhaps the most important technical parameter that affects driving performance, and the classic solution is a rigid flooring of water-resistant plywood coated with a coating. Plywood slugs provide excellent rigidity of the hull, which allows the boat to keep the course more confidently and easier to get on plane.
However, modern technology offers an alternative in the form of low- or high-pressure inflatable floor (HPD), models with NDND are assembled much faster, since there is no need for tedious stacking of heavy plywood sheets, and inflatable floor provides better shock absorption on the wave, making swimming more soft and comfortable.
When choosing between plywood and inflatable floor, consider the weight of the kit. Plywood longelons and floorboards add significant weight, which can be critical when carrying equipment over long distances. inflatable floor High pressure (AirDeck) in rigidity is almost not inferior to plywood, but in the assembled form takes much less space.
☑️ Choosing a bottom type
It is important to note that the hardness of the bottom directly affects handling, the soft bottom can bend under the weight of passengers, increasing the resistance of the water, so for high-speed driving, it is preferable to choose models with a rigid deck or high-quality BND.
Technical specifications of popular models
To make a visual comparison of the various modifications, we will give a summary table of the main parameters, which will help you navigate the range and choose the best option for your tasks and the existing engine.
| Model | Length (cm) | Width (cm) | Load capacity (kg) | Engine power (hp) |
|---|---|---|---|---|
| Compass 290 | 290 | 136 | 400 | 5 |
| Compass 320 | 320 | 145 | 500 | till 9. 9. |
| Compass 340 | 340 | 150 | 600 | 15 |
| Compass 380 | 380 | 160 | 750 | 20 |
As you can see from the table, as you increase the size, not only the capacity increases, but also the allowable power of the engine, which allows you to use more traction engines that can bring a loaded boat to plane even with two passengers and equipment.
⚠️ Warning: Exceeding the recommended power of the motor can lead to the destruction of the transom and loss of control of the vessel, which poses a direct threat to life.
Package and additional accessories
Standard equipment usually includes the boat itself, removable seats (banks), a pump, a remix and a packing bag. However, to fully operate, it often requires re-equipment. transom wheels It greatly facilitates the movement of a motorized boat on the shore, eliminating the need to drag heavy loads manually.
It is also worth paying attention to the possibility of installation sonar Many models have special platforms or sensor attachment, and safety rails around the perimeter of cylinders are a necessary safety element to keep overboard in an emergency.
- 🎣 Comfortable seats with soft padding increase comfort during long fishing.
- ⚓ The anchor rum and leer system simplify anchoring and mooring.
- 🔦 The possibility of installing running lights is mandatory for night navigation according to the rules of GIMS.
When buying a boat, immediately check the presence of valves for venting excess pressure (automatic or manual), this will save the cylinders from bursting in the sun.
Rules of operation and care of PVC
The durability of your boat depends on proper maintenance, and after each operation, especially in salt water, the boat must be thoroughly washed with fresh water, and salt, sand and silt act as an abrasive, gradually destroying the protective layer of the material. Suit before packaging is a critical step to prevent mold and unpleasant odor.
Store the product in a straightened form at room temperature, away from the heaters. If this is not possible, it is allowed to store in a deflated state, but it should be folded carefully, avoiding the formation of permanent cavities in the same places. It is recommended to periodically treat PVC with special means to restore elasticity.
In winter, storage is best done in a warm environment, and although modern materials can withstand low temperatures, PVC becomes tougher and more vulnerable to mechanical damage in the cold. Puncture repairs at home is possible with the help of a remplekt, but requires compliance with degreasing and gluing technology.
Regular washing and complete drying of the boat before packaging increase its service life by 2-3 times.
Frequently Asked Questions (FAQ)
Can I use the Compass boat in sea conditions?
Yes, many models of the 320 series and above are made of marine PVC and have a reinforced design, which allows them to be operated in the coastal zone of the sea, but you should take into account the height of the wave and the distance from the shore.
Which motor is better for a 320-length boat?
The optimal choice for the model length of 3.2 meters will be a two-stroke engine with a capacity of 9.9 hp This will provide a confident planing with one or two passengers. For three people or heavy loads, it is better to consider the engine 15 hp.
How to properly pump the cylinders of the boat?
Pumping should be done to a pressure of 0.2-0.25 atmospheres (or until the side becomes elastic to the touch). It is important to leave a small margin, as the pressure inside the cylinders will increase in the sun. Use a gauge for accuracy.
Is there a guarantee for punctures and cuts?
The manufacturer's warranty usually applies to defects of materials and seams. Mechanical damages received during operation (punctures, cuts, burns), are not a warranty case and are eliminated at the expense of the owner.
