PVC inflatable boats have long ceased to be just a means for crossing the river, becoming full-fledged boats for serious fishing and recreation. However, the standard equipment often does not meet the needs of experienced water engines, especially in the field of attachment equipment and improving driving performance. targa A metallic design that changes the functionality of your boat.
Installation of such a frame allows you to take boat-engine It's also convenient to attach sounders, navigators and even running lights to the crossbar, making the inflatable sounder akin to the boat and the console, and in this article we'll look at whether the sheepskin is worth making, and how to make or choose this tuning element.
Why you need Targa on an inflatable boat
Substantive function target The engine is basically a shifting point of the engine attachment, and the standard motor is attached directly to the transom, which creates a characteristic noise and vibration that is transmitted to the entire body. When you take the motor back on a special frame, the sound wave goes overboard, and in the cockpit becomes much quieter, which is especially important when you catch a predator, when unnecessary sounds can scare the fish away.
The second important aspect is aerodynamics Targa is often used as a mounting point for an awning or a canopy that protects against sun and rain. keel-drive or dolphinarists, which cut the oncoming flow of water under the bottom, improving the yield on plane and stability of the course on the wave.
⚠️ Attention: Targeting shifts the boat's center of gravity, and without properly balancing the crew or shifting the tank forward, the boat's nose can start to pick up, which is dangerous on high waves.
And ergonomics, too, can be used to pin the spinning holders, or the cartplotter tablet, or the bar. sonarIt's a tool that frees up your hands and allows you to control things without being distracted by the gear, and it turns the boat into a mobile fishing platform.
Design features and materials
When choosing or manufacturing a frame, the material is critical. stainless steel (AISI 304 or AISI 316) or duraluminum. Stainless steel is heavier, but much stronger and more durable in an aggressive salty environment. Aluminum alloys are lighter, which is important for small boats, but require more careful care and quality anodizing.
The design is an U-shaped or more complex frame that is attached to cylinders or a transom through a system sling and The most important element is the way the cylinders are attached: modern models use rigid plates that lie on the cylinder, or special "ears" that cover it, which prevents the target from shifting during sudden maneuvers or shocks against the wave.
The geometry of the product also plays a role: the height of the racks should be sufficient so that the motor does not touch the transom during the rise of the daywut, but does not create an excessive sailing effect. The width of the bar usually corresponds to the width of the transmuner or slightly exceeds it, allowing for symmetrical installation of the equipment.
Comparison of materials
Stainless steel AISI 316 withstands heavy loads on kink and is not afraid of scratches, but weighs about 40% more aluminum. Aluminum tarmac (D16T) is ideal for boats up to 3.6 meters long, where every kilogram counts, but they require careful operation and do not tolerate impacts on stones.
Impact on driving performance and glossing
Many PVC boat owners mistakenly believe that the targa only weighs the design. keel It does wonders. The flow of water under the bottom becomes more laminar, which reduces drag and allows the boat to get on plane mode faster.
When operated with powerful motors (15 hp and above), the targa helps stabilize the stern. The boat stops scouring, especially in lateral waves. This reduces driver fatigue and improves navigation safety. However, if the targa is too massive, it can act as an anchor in the water, creating additional resistance.
- 🚀 Improvement of the output for gleaming due to the work of the dolphinar.
- 🌊 Reduce yaw and improve exchange rate stability on the wave.
- 🔇 Significant reduction in noise and vibration in the cockpit area.
- ⚖️ Possibility of more accurate balancing of the boat by moving the motor.
It is important to understand that the effect depends on the angle of installation of the motor itself relative to the transom, and the Targa allows you to vary this angle more flexibly than the standard transom, finding the optimal position for a particular engine and loading the boat.
Targa with integrated keel-dolfinator works like a hydrofoil, pressing the stern and improving the output to the plane, but only with the correct installation of the angle of inclination of the motor.
Instructions for installing targas yourself
Installation requires care and technology, because it's about safety. Before you start, make sure that the cylinders are pumped to the working pressure. The installation process begins with fitting: the frame is placed on the cylinders at the transom, and the exact location of the belts is determined.
Then comes the locking stage. They use fastexes to pass through the frame's eyelets and cover the cylinders, and it's critical that you don't pull the belts to the string state, but you don't leave them hanging around, and you have to fit tightly to the surface of the PVC without damaging it.
☑️ Pre-installing check
Once the belts are installed, the motor itself is mounted on the bracket, where you need to check the horizontality of the installation of the data-devut. If the motor is curved, the boat will be led aside. Adjustment is done by placing gaskets or changing the tension of the fasteners.
⚠️ Warning: Never attach the targa to just one cylinder or asymmetrically, this will cause the structure to be distorted and can cause the boat to tip over when a sharp turn.
The final step is to test the reliability of all the connections on land, and try to force the structure to move in different directions, and if there are no backlashes, you can launch the boat for test runs.
Self-manufacturing: drawings and calculations
For craftsmen who are friendly with welding and tubing, manufacturing target The main material is a stainless steel pipe with a diameter of 25-30 mm with a wall thickness of at least 2 mm. The use of a thinner pipe is unacceptable due to high vibration loads.
The first step is to create a sketch. You need to know the width of your boat's transector and the desired height of the engine. The standard height of the rack is about 40-50 cm from the level of the inflated cylinder. The bar should be 10-15 cm wider than the transom on each side for symmetry.
The approximate dimensions for a boat 3.6m:Transnant width: 450 mm
Target width (total): 700 mm
Stand height: 450 mm
Pipe diameter: 25 mm
When welding, it is important to use argon arc welding (TIG) so that the seam is strong and does not corrosion. After welding, the seams must be cleaned and polished. Pay special attention to the places where the belts are attached - reliable hinges or ears made of the same stainless steel should be welded there.
When welding stainless steel, be sure to use argon purging from the inside of the pipe to prevent “reverse sugar” (oxidation of the metal inside the seam) which drastically reduces the strength of the structure.
Safety and operating rules
Operating a boat with a set target imposes additional obligations on the owner, first of all, it is the monitoring of the condition of the fasteners. Belts. and fastex They are exposed to UV and salt water, which over time reduces their strength, and regular inspection is mandatory before each exit.
The size should also be considered. The boat with the target becomes higher, which increases sailing. In a strong lateral wind, controlling such a boat requires more caution, especially at low speeds. The center of sailing shifts upwards, which increases the risk of overturning.
| Parameter | Norm/Requirement | Risk of violation |
|---|---|---|
| Condition of the belts | No cracks or scuffs. | mounting break, loss of motor |
| Pressure in cylinders | Strictly passport (usually 0.2 atm) | Deformation of the cylinder under load |
| Motor attachment | Tight, no backlashes. | Vibration, destruction of the transmunus or frame |
| Balancing | Equal weight distribution | Overturning, nose-buried |
Keep in mind that targa is not only a convenience, but also an additional responsibility. Compliance with safety rules will allow you to enjoy fishing without worrying about the technical condition of the boat.
Frequently Asked Questions (FAQ)
Will the speed of the boat decrease after setting the target?
With proper installation and the presence of aerodynamic keel speed can even increase due to improved planing. However, if the frame is too massive or has poor streamlined, loss of 1-2 km / h is possible due to weight gain and air resistance.
Can I leave the motor on the target during transportation?
When transporting on a trailer or roof of a car, vibrations and wind loads occur, which can damage both the target and the engine mounts.
Will Targa be suitable for a boat 3 meters long?
For boats less than 3.2-3.4 meters long, a full-fledged targ is often impractical due to the loss of useful cockpit area and overweight, in which case it is better to consider lightweight aluminum options or limit yourself to a dolphinarist per transom.
How often should the belts be changed?
The life of the belts depends on the operating conditions. When used in salt water and in the sun, it is recommended to conduct a thorough diagnosis every season and change the set of belts every 2-3 years, even if they appear to be intact visually.
