Compass inflatable boats: from model selection to DIY tuning

Choosing a boat for fishing or a family holiday on the water is often a daunting task, especially when the budget is tight and the quality requirements remain high. PVC Compass boat For many years, it has been a strong market for inflatable vessels, offering the best value for money and reliability, and these vessels, manufactured in Novosibirsk, have earned a reputation as workhorses through the use of quality materials and thoughtful design.

The owners of these boats appreciate their functionality and ability to upgrade, but like any technical tool, they require the right approach to operation and maintenance. In this article, we will discuss in detail the key features of various modifications, discuss the nuances of choosing an engine and give practical tips for extending the life of your vessel.

Understanding the technical specifications and design features will allow you not only to buy the perfect boat, but also competently maintain it for many years. compass It is a brand that is familiar to most boaters, and knowing its specifics can make your life on the water much easier.

Key features and advantages of the design

The basis of the durability of any inflatable boat is the material from which it is made. Compass Traditionally made from five-layer reinforced fabric PVCThe material density varies from 750 to 900 g/sq.m., which provides an excellent balance between the weight of the product and its strength.

The production of the joints is particularly focused on the quality of the joints, and the gluing method is used to ensure that the joints are tight even in long-term use in an aggressive environment. prairie, which allows you to install outboard motors with a capacity of up to 15 hp. depending on the model.

• 🛡️ Defense: The presence of a timber around the perimeter protects the sides from impacts on the piers and sharp objects.
• 🧱 Construction: The division into independent inflatable compartments ensures unsinkability even when one of the cylinders punctures.
• ⚓ Convenience: Built-in anchor rings and liner stretches simplify fixing equipment and mooring.

The design of the bottom also plays an important role, depending on the series, boats can be equipped with a low-pressure inflatable floor (LDPB) or a floorboard aluminum floor. NDMA It provides better cruising and less weight, whereas the floorboards provide a rigid platform, convenient for moving inside the cockpit.

Overview of popular series and models

The manufacturer offers several lines, each of which is sharpened for specific tasks. CompactIt's a lightweight, compact, assembled squirt, ideal for boat-trailer fishing or mobility-oriented.

For more serious tasks, a series is intended. ProThese models have increased load capacity, wider cylinders and reinforced design. Boats Pro Often chosen for the installation of more powerful motors and use in large water conditions or reservoirs.

Special attention should be paid to models with an abbreviation M The name means inflatable bottoms, which are faster to assemble and weigh lighter, but require more careful handling of the bottom surface. Below is a comparison of the technical specifications of popular models.

Model	Length, cm	Width, cm	Load capacity, kg	Weight, kg
Compass 320	320	145	450	38
Compass 360 Pro	360	165	650	52
Compass 420	420	175	800	68
Compass 290 Compact	290	135	350	29

The choice of a particular model should be based not only on the number of passengers, but also on operating conditions. 290-320For example, it is better to consider the options for Ladoga or Onega from 360 Pro and higher.

Choice of motor and attachment equipment

The right engine is the key to comfortable operation. For boats up to 320 cm long, the best choice will be engines with power. 5-6 hpThey allow you to reach speeds of 20-25 km/h, which is enough to travel to the fishing point. Tohatsu or Yamaha In this class, they have been very successful in Compass.

For series models Pro And more than 3.6 meters long, it makes sense to consider engines with a capacity of 9.9 hp with the possibility of tearing up to 15 hp. This will allow you to get on plane even with a full load and two passengers on board. turret The boat must withstand the weight and vibration of the chosen motor.

⚠️ Attention: Never exceed the maximum recommended engine power specified in the boat's passport, which can cause the transom board to collapse and the boat to tip over at full speed.

And don't forget the attachments, the anchor rum, the rod holders and the sonar greatly enhance the comfort of fishing. Installation of trans-wheels It will make it much easier to launch a boat and lift it to the shore, especially if you often change parking places alone.

• 🎣 Echoer: For fishing from a PVC boat, a sonar with a mount on a transom or board is mandatory.
• 🔋 AKB: Use special traction batteries that are resistant to vibration and roll.
• ⛽ Buck: For long-distance exits, purchase a remote fuel tank with a volume of 12-25 liters.

How to prolong the life of a motor on a PVC boat?

Rinse the cooling system regularly after use in salty or muddy water, and monitor the condition of the lower unit foot - any scratches should be immediately painted with anti-corrosion paint to avoid oxidation of aluminum.

Instructions for proper assembly and pumping

The durability of a boat depends on how you inflate it. Using a car pump without a pressure gauge is a common mistake. Excessive pressure in the heat can cause the seams to rupture, and insufficient pressure can cause the structure to deform and lose driving performance.

The assembly process should take place on a clean surface. Remove sharp stones, branches and thorns. Inflating. It should be made in stages, first filling the cylinders by 50-60%, then leveling the structure and achieving the nominal pressure.

It's important to remember that the temperature expansion of the air is very important, because if you pump the boat in the shade or garage and then take it out in the sun, the pressure inside the cylinders will increase. blow outto avoid overstraining of the material.

Pay special attention to the valves. Make sure they are tightly closed and free of contamination. Dirt or sand trapped in the valve thread can cause slow etching of air, which is only found on the water.

Maintenance, repair and storage

After each operation, the boat must be washed with fresh water, especially if you have been swimming in a salty body of water. The salt crystallizes and can damage the fabric and seams. Drying is a critical step: keep the boat only completely dry, otherwise it may appear inside. mold And fungus that destroys the reinforcing layer.

Small punctures are easily repaired with a standard delivery remix, requiring a piece of cloth, adhesive (usually polyurethane) and a degreaser, and the puncture site is cleaned, degreased and warmed up.

⚠️ Attention: Do not use chloroprene-based adhesives (for example, "Moment" classic) for repairing PVC boats without special preparation, as they may not provide proper seam elasticity. It is better to use specialized two-component adhesives for PVC.

Keeping the boat in limbo is best, but it's not always possible. When you keep it in a bag, avoid sharp clamps. Periodically, once a season, the boat needs to be inflated and checked for microcracks or loosening of seams.

Tuning and modernization DIY

Many owners don't stop at the factory and do tuning. One of the most useful improvements is the installation. stringer It's a big improvement in fluid dynamics and it allows the boat to go out and planing faster.

There are also popular attachments to extra hazelnuts and gearboxes, which can be mounted on floorboards or sides with Velcro straps and belts, and you can also reinforce the bottom with keel tape or protective strips, especially if you often dock on rocky shores.

• 🛡️ Keel: Installation of a removable keel improves the course stability.
• 💡 Lights: Installation of LED tape around the perimeter of night fishing cylinders.
• 🪑 Comfort: Replacement of regular cans with soft inflatable seats with backs.

Trans tuning is also common, such as installing transom plates or strengthening the engine attachment with additional linings, which is important for those who use powerful motors or often move in shallow waters where the risk of hitting the bottom is high.

Where do I get the tuning parts?

Many items, such as dips, handles, valves and even pieces of fabric, can be found in specialty PVC stores or ordered from the manufacturer, and powerboating forums are also popular, where used elements are sold or drawings are shared for self-made.

The key to modernizing is not to overload the structure, because the extra weight of the equipment reduces the payload and reduces the seaworthiness, and all changes must be considered and justified.

Frequently Asked Questions (FAQ)

What is the optimal pressure in the cylinders of the Compass boat?

The optimum working pressure is 0.2 atm (about 0.2 kgf/cm2). Exceeding this value will not add stiffness, but will create excessive stress in the seams, especially in the sun. Insufficient pressure (less than 0.15 atm) will lead to "softness" of cylinders and deterioration of handling.

Can I leave a PVC boat in the sun for a long time?

Ultraviolet destroys the structure of PVC and glue, if the boat is on the water, try to hide it in the shade or cover it with an awning, prolonged exposure to direct sunlight reduces the life of the material by many times.

What is the difference between the boat Compass and other brands (Flagman, Cayman)?

Compass Often wins in price with similar specifications, offering good enough quality for amateur use. Flagship often has more complex design solutions (for example, BND in the database), and Cayman. It's famous for being indestructible, but it can be harder, and it depends on whether you're going to prioritize price, weight or maximum strength.

How to properly glue a puncture if there is no special glue at hand?

In emergency cases, you can use epoxy glue with a plasticizer, but this is a temporary solution. For reliable repair, you need polyurethane glue for PVC. Superglue (cyanacrylate) can not be used, it will become brittle and fall off on a bend, damaging the fabric.

Do I need to clean the valves before the season?

Yes, rubber valve seals are useful to lubricate with silicone lubricant, which will prevent rubber from drying out, make it easier to twist and ensure better tightness. Don't use petroleum products (oil, gasoline), they break down rubber.
