The modern market of swimming aids offers a wide range of solutions for lovers of active recreation on the water, among which stands alone. transmesseIt is not just an inflatable raft, but a complete vessel capable of withstanding heavy loads and speeding with the possibility of installing an outboard motor, and has undergone a significant evolution in design from simple rubber rounds to high-tech PVC reinforced complexes with rigid or inflatable reinforcement elements.
The main advantage of these models is their versatility, you get at the disposal of lightweight and compact in folded form of transport, which is not inferior in performance to many body counterparts. Tough transnectorThe stern, built into the aft part, allows you to mount engines with a capacity of up to 30 hp and more, which opens up opportunities not only for quiet fishing, but also for planing, water walks with family and even rescue operations.
However, choosing such equipment requires a deep understanding of technical nuances. Incorrectly selected motor or violation of operating rules can lead to damage to cylinders, deformation of the bottom or, worse, to an emergency on the water. In this article, we will discuss in detail the design features, selection criteria and rules of operation, so that your familiarity with the water element is exceptionally positive.
Design features and types of transom
The basis of reliability of any flyboat It's built in a way, especially in the aft part, where the engine is attached, and it's where the maximum loads are concentrated in driving and in turbulence, and manufacturers have different approaches to transom-strengthening, and each has different advantages for specific tasks.
There are two main types of transverses: glued and removable. The glued version is a plywood or composite plate that is stuck between the cylinders and coated with a protective layer. maximum rigidity It's also tight, and it doesn't get water inside the cylinders through the fasteners, which is the perfect choice for constant use and high-powered motors.
Removable transoms are more common in budget models or small boats, they are inserted into special pockets between cylinders. Although this makes it easier to repair and replace the element, when used actively, such models can leak water at joints, and the plywood itself eventually dries up. For serious loads, it is preferable to glue the version with perimeter reinforcement.
⚠️ Attention: Never use a removable transatlant with a motor above the manufacturer's recommended power. Excessive traction can pluck plywood from your pockets, causing instant flooding of the feed and loss of control.
The most important element is the material of the transom, which is usually moisture-resistant plywood, coated with special paint or plastic, and the quality of this treatment directly affects durability: the cheap coating cracks quickly, allowing water to penetrate the layers of wood, which causes swelling and rotting.
Manufacture materials and PVC strength
When you're choosing a boat, you should first consider the density and structure of the material. reinforced polyvinyl chloride (PVC) This is not a conventional film, but a complex composite material consisting of several layers, between which a grid of synthetic threads (cord) is laid.
It is the presence of a cord that gives the material the ability to withstand high pressure and mechanical shocks. The density of the fabric usually varies from 750 to 1100 g / sq.m. For single boats under a low-power engine, 750-850 g / sq.m. If you plan to plane, carry heavy loads or walk on rocky shores, you need a material density of 900 to 1,100 g/sqm.
Special attention should be paid to seams. In high-quality products, the hot gluing method is used, where the layers of PVC are fused under pressure and temperature, becoming a monolith. Cold gluing on the glue can eventually dry out, especially at temperature changes. Check the seams for bloating or unpatched areas in the store.
Effects of PVC temperature
When operating in cold weather (below +5°C), the PVC material becomes less elastic and more susceptible to impact, and in such conditions avoid sudden movements and impacts on solid objects, as the risk of damage to the shell increases many times over.
The durability of the material also depends on the presence of protective layers against ultraviolet light and oils. Cheap analogues can fade and lose strength after one season of active sun. reinforced PVC It will last for years if you take care of it properly.
Criteria for choosing a boat for an outboard motor
Choice transmesse It's a compromise between the load capacity, the weight of the boat itself, and the power of the engine that's being planned, and a miscalculation can lead to the boat either digging its nose or not going to plane, wasting fuel.
The first is length. To get on plane (a mode where the boat glides over the water rather than pushing it), the hull must be at least 2.8-3.0 meters long. Shorter models, even with a powerful motor, will remain in displacement mode, which limits the speed of 10-12 km / h.
The second criterion is the presence of an inflatable keel. The keel cuts off the wave and improves the course stability. Without the keel, the boat will prowl from side to side, especially in the wave or in the side wind. For motors from 5 hp, the presence of the keel becomes mandatory comfortable and safe operation.
Also consider the carrying capacity. rated carrying capacity is the weight at which the boat is still afloat, but it is not a fact that it will be controlled. The real payload for comfortable fishing with the engine should be no more than 70% of the passport, this will ensure a high board and good germination on the wave.
Installation and configuration of the outboard motor
The right engine to the transom is a key factor in speed, fuel consumption and safety, and it's rods that attach the motor to the top edge of the transom, and it's important to place it in the center and tighten the fasteners securely, using rubber or plastic pads so that you don't damage the transom's coating.
The critical parameter is the height of the installation of the daydvut (the bottom of the engine with a screw). If the motor is set too high, the propeller will capture air, which will lead to loss of traction and overheating of the engine. If it is too low, water resistance will increase, and the boat will lose speed.
☑️ Check before the first launch
To adjust the height, a hole in the lower unit is used: when moving, the nose of the anti-cavitation plate should be at the level of the bottom of the boat or 1-2 cm lower. The exact adjustment is made experimentally on the water: if the boat's nose is up and the screw "takes air", the engine should be lowered.
Don't forget the angle of the trim, and by adjusting the angle of tilt with a pin or a hydraulic lift, you change the position of the boat relative to the water, and the right angle allows the boat to go out and plane faster and save fuel.
⚠️ Attention: Always use a safety cable (check), one end of which is attached to the motor and the other on the operator's clothes or life jacket, and if a person falls overboard, the engine will instantly stall, preventing tragedy.
specifications comparison table
To organize the information and help you make the right choice, we compare the main types of transoms-inflatable boats available on the market, which are averaged for models of the same size class.
| Parameter | Budget model (PVC 750) | Middle class (PVC 900+) | Premium segment (PVC 1100) |
|---|---|---|---|
| Material density | 750 g/sqm | 900-950 g/sqm | 1100 g/sqm and above |
| Type of stitches | Cold gluing | Combined | Hot melting |
| Max, engine power. | up to 5 hp | 15 hp. | up to 30 hp and more |
| Underbody design | Pyol (plywood) | NDD or pyeol | BDLD |
| Term of service | 3-5 years | 7-10 years | 10-15 years |
As you can see from the table, the price difference is often due to manufacturing technology and safety margin. For frequent use and plane, the savings on the material class can come out sideways in the form of rapid wear.
Models with NDMA (low pressure inflatable floor) allows the boat to be assembled without the use of rigid floorboards, which greatly speeds up the preparation process and reduces the overall weight of the kit. However, for serious glides with a heavy engine, the classic plywood bottom is often preferred because of better hydrodynamics.
Care, storage and security
The inflatable boat requires regular maintenance to maintain its performance. After each foray into the water, especially if it was salt water, the boat must be rinsed with fresh water. The salt, sand and silt act as an abrasive, gradually destroying the PVC protective layer.
Drying is a must before packaging. Even a minimal amount of moisture inside the cover can cause mold that breaks down the fabric and an unpleasant odor. Dry the boat in the shade: direct sunlight on the inflated boat can cause the seams to rupture due to thermal expansion of air.
Use talc or a special powder to treat the inner surfaces of the inflatable floor (NDB) before long-term storage. This will prevent PVC layers from sticking together and make it easier to pump the boat next time.
Keep the boat in a warm room, if not possible, make sure that when folded, heavy objects do not press on it. Periodically (once a season) check the pressure in the cylinders and the condition of the valves.
Safety on the water is priority number one. Always carry a life jacket by passenger number, an anchor with sufficient line and remix. Remember that an inflatable boat is vulnerable to sharp objects, and having a patch and glue in the first aid kit can save the situation away from shore.
Regular inspection and proper storage increase the service life of an inflatable boat by 2-3 times, maintaining its tightness and appearance.
Frequently Asked Questions (FAQ)
Can I install an electric motor on an inflatable boat with a transcenza?
Yes, you can. Most trans transes have standard mount sizes that are suitable for both gasoline and electric motors, and it's important to consider the weight of the battery, because electric motors require heavy batteries to be placed, which affects the weight of the boat.
Which glue is best for PVC repair?
For quality repairs, use two-part polyurethane adhesives (e.g., isocyanate-based adhesives) that create a seam that is as strong as the material itself. Conventional household adhesives like Momenta only have a temporary effect and cannot withstand water stress.
Do I need to register an inflatable boat with an engine?
Registration with GIMS is required if the weight of the out-of-load vessel (boat + engine + equipment) exceeds 200 kg, or if the engine power exceeds 8 kW (about 10.8 hp). However, the rules may change, so it is better to check the current information at the local GIMS office.
What pressure should be in the cylinders?
The optimum working pressure is usually 0.2–0.25 atmospheres (about 200–250 mbar). Excess pressure is dangerous in hot weather due to the risk of rupture, and insufficient pressure leads to deformation of cylinders and reduced stability of the boat.
