Many owners of inflatable vessels, at the first glance at the rigid structures towering above the stern, wonder: is it really necessary or just an extra waste of budget and weight? Targa It's not just an aesthetic to make a boat look like a speedboat, it's a functional solution that fundamentally changes how we operate on the water, and the owners who have installed it say they're more comfortable and more capable, especially when they're going long journeys or fishing specific ways.
Structurally, the targa is a frame, usually made of stainless steel or aluminum, which is attached to the transom or cylinders in the aft part. PVC boatsThe main purpose of this device is to remove the attachment point. outboard It is higher and further from the transom, allowing more powerful power units to be used without risking damage to the stern, and it also provides a reliable support for navigation equipment, awnings and additional accessories, turning a conventional rowing or motor boat into a full-fledged small craft.
However, the introduction of such a design requires a balanced approach, since not only the appearance, but also the appearance of the system changes. centre-up A frame that is not properly fitted or fitted can have a negative impact on stability and handling, especially on the wave, and it is important to understand the physics of the processes that occur when moving, so that modernization can only benefit.
Main functions and advantages of installation
The main reason fishermen and waterwalkers decide to set a score is the possibility of using a more powerful motor. The standard transom of an inflatable boat is often limited in power due to design features and the risk of deformation under the weight of a heavy engine. Targa redistributes the load, transferring traction force not only to the transom, but also to the board through the mounting system, or completely takes the weight of the motor on itself, depending on the design.
The second critical aspect is the ergonomics and the placement of the equipment, which can be mounted on the frame with a sonar, GPS, spinning holders and running lights, and frees up space inside the cockpit, which in small boats is often critical to the placement of catches or gear. Navigational instrumentsThe sleeves raised to the level of the helmsman's eye provide better visibility and ease of control.
Also worth noting is the protection feature: When installing a tent-transformer, the targa serves as a framework to provide a complete shelter from rain or the scorching sun, which turns the boat into a camping option suitable for multi-day expeditions, and also protects passengers from spray from the screw and from engine exhaust gases, guiding them higher.
- 🚀 Allows you to install a motor of greater power than the manufacturer recommends for a standard transom.
- 🎣 Frees the inner space of the cockpit by removing equipment to the frame.
- ⚓ It serves as a reliable frame for installing a running awning or bimini.
- 🔦 It allows you to fix navigation lights at the correct height according to the rules of GIMS.
⚠️ Attention: Targeting shifts the boat's center of gravity, and be prepared for the boat to become more sensitive to roll, and adjustments to the load and passengers will be required to maintain optimal cruising.
Impact on driving performance and centering
Any interference in the design of the vessel entails a change in its hydrodynamic specifications. TargaThis can cause the boat to bury its nose more when it's planing, or it can lose its ability to exit the glider when the engine is low, and it's critical to consider the weight of the frame and the equipment it's mounted.
When driving at high speeds, the sailing structure can create resistance to the wind. If the targa is high and massive, it works like a sail, which makes it difficult to operate in windy weather and increases fuel consumption. Aluminum models are preferable in this regard, since they are lighter and often have more streamlined pipe profiles. Aerodynamics It plays a role not only in speed, but also in the stability of the course.
On the other hand, a well-chosen targa can improve the differing, and by taking the engine back and up, we change the angle of attack of the bottom, and it can help to pull the bow of the boat out of the water if it's skewed by the stern, but there's a fine line here: too strong a rear differentiator will lead to yaw and reduce stability on the straight.
Types of constructions and materials of manufacture
The market offers a variety of solutions, depending on the budget, the size of the boat and the purpose of operation, the main materials are two: stainless steel and duraluminium (aluminum-magnesium alloys), steel targets are high strength and relatively low cost, but have a significant weight. Stainless steel resistant to corrosion, but requires high-quality coating of welds to avoid the appearance of rust in places of violation of the protective layer.
Aluminum structures are lighter, which is their main advantage: they do not rust in principle, although they can oxidize to form a protective film. Such tariffs are often made collapsible for easy transportation. They can be combined on bolts or with special fittings. The weight of such a frame can be 2-3 times less than a steel counterpart, which is critical for small boats up to 3.6 meters in length.
By type of attachment, the targas are divided into transoms and inflatables (attached to cylinders); transom models are rigidly fixed on the transmuter, transmitting vibration to the entire body; models attached to the cylinders through slings or special pockets, softer in operation, but require perfectly pumped cylinders and condition of attachments. Combined options They are less common, but provide maximum stiffness.
| Characterization | Stainless steel | Aluminum alloy (Dural) | Mixed construction |
|---|---|---|---|
| Weight. | Tall (8-15 kg) | Low (3-6 kg) | Medium. |
| Price. | Medium/Affordable | High. | Medium |
| Corrosion | Possible (requires care) | Not affected. | Depends on care. |
| Toughness | Maximum | High. | High. |
Nuances of installation and anchorage to the transom
Tagging is a process that requires care and precision. Mistakes at this stage can cause damage to the boat or loss of the engine on the go. The first step is always to try on. You need to make sure that the fasteners do not rub against the cylinders or squeeze them excessively. To protect PVC fabric in the contact areas, it is recommended to use additional pads made of dense rubber or neoprene.
The attachment to the transom is usually done by clamping or bolt joints through the holes in the transom plate. If the transom is hinged, it is important to check its rigidity. transom plate It has to be reinforced to withstand not only the weight of the motor, but also the lever created by the target, and often requires the installation of additional wooden or aluminum pads inside the cockpit to distribute the load.
When assembling collapsible structures, thread fixers should be used (for example, Loctite 243), as engine vibration can unwind even well-tightened nuts in a few hours of operation, regularly check the tightening of all connections, especially after the first outlet to the water, weakening of the fastener is a common cause of frame skewing and damage to the attachment sites.
☑️ Check before first exit
Pay special attention to the height of the installation. Too low a targa can interfere with the viewing or creation of waves, too high will raise the center of gravity. The optimal height is usually selected experimentally, but the starting point is a position where the engine's lower unit is in the same plane as the boat's keel or slightly higher.
Use of Targa for Fishing and Rest
For anglers, the Targa becomes a real command center, and you can attach downriggers to troll on the crossbar, which allows you to catch deep horizons. trolling And the rods are fixed securely, and the frame is often mounted with spinning holders, side-scanning sonars and map tablets.
In the context of leisure and tourism, the possibility of installing an awning is crucial: a tent-transformer on the frame of the targa allows you to spend the night in a boat sheltered from dew and insects, or to wait out a sudden downpour. This turns PVC boat into a miniature cabin boat. For family holidays, this is the opportunity to create a shadow over passengers, which is important on hot summer days.
Safety is also important, because the upper bar is often marked with running lights, which make the boat visible in the dark and fog, in accordance with the rules of navigation, and you can place a flag, flares or a lifeline that will always be at hand and in sight.
Maintenance, maintenance and storage of the structure
Metal structures that are in constant contact with water require regular maintenance, after each exit, especially on salt water, the targa must be rinsed with fresh water, salt is a powerful catalyst for corrosion, and even stainless steel It can suffer from pitting corrosion in welding or scratching areas, and simply rinsing it will significantly extend the life of the product.
When stored in the off-season, it is recommended to dismantle the targa if the design allows it to do so. It is better to store it in a disassembled form in a dry room, packing the elements in soft cloth or bubble wrap to avoid mechanical damage and scratches. If dismantling is not possible, cover the boat with a case, providing ventilation to avoid condensation.
Periodically inspect the anchorages to the boat. PVC fabric tends to wear out from friction and load. If you notice scuffs in contact with slings or clamps, immediately replace the safety pads or tighten the mounts. Timely maintenance will prevent expensive repair of cylinders.
⚠️ Attention: Never use abrasive powders or hard metal brushes to clean the label, which will damage the protective oxide layer on aluminum or stainless steel polishing, opening the way for corrosion.
Comparison of cost and feasibility of purchase
The cost of the tariff ranges from a few thousand rubles for simple Chinese models of pipes to tens of thousands for branded aluminum designs with perfect geometry. You need to honestly answer yourself: does the functionality justify the cost? If you have a boat 3.2 meters long with a 5 hp engine, the targa is likely to be an excess that will only worsen the performance.
But for boats ranging in length from 3.6 meters and engines from 15 to 20 hp, the setting of a score becomes almost a necessity for comfortable operation. The ability to put a 30-40 hp engine instead of a regular 15 hp completely changes the dynamics and safety of the vessel on high water, in which case the cost is paid off with comfort and advanced capabilities.
Also worth considering is the option of self-manufacturing (DIY), many craftsmen brew the targas from stainless steel pipes themselves, which allows you to save up to 50% of the cost, the main thing is to comply with the welding technology and not overheat the metal, so as not to violate its anti-corrosion properties. Homemade targa can be adapted specifically for your needs better than factory.
Final recommendations for selection
When choosing a targa, be guided not only by price, but also by the quality of welding and equipment. Having all the necessary bolts, pads and instructions is a sign of a good manufacturer. Avoid designs with sharp corners and burrs that can tear fabric or injure hands. Security Reliability should be a priority.
Be sure to consult the seller or manufacturer of the boat regarding the compatibility of a particular model of the tariff with your boat. Other manufacturers may have their own nuances of mounting transom and shape of cylinders. There are no universal solutions, and what is ideally sat on a friend's boat may not suit you.
Ultimately, Targa is an investment in your boat, giving you freedom, comfort and security to enjoy the water to the fullest, weigh the pros and cons, assess your needs, and make choices that will make your boat the perfect tool for fishing or recreation.
☑️ Final checklist before purchase
Can I set the targa on the boat without a transom plate?
Tagging a boat without a rigid transom plate is possible, but not recommended for high-powered motors, such as using special adapters or reinforcing the transom with additional linings, but loading the soft transom can cause it to deform, so it is better to consider the options for attaching to cylinders or installing a full-fledged stove.
Is Targa sailing hard in the wind?
Yes, targa increases the sailing speed of the boat. At high speeds, this may be invisible, but when you go against the wind or at low speeds (trolling), resistance is palpable. Aluminum profiles of streamlined sails are smaller than designs of large-diameter round pipes.
Do I need to remove the targa when transporting on a trailer?
Not necessarily if the size of the boat with the targa fits into the norms for transportation without special permission. However, if the targa is high, it can increase the wind load on the trailer. Many owners prefer to remove the upper bar or the entire structure to reduce the center of gravity and aerodynamic drag when driving on the highway.
How does Targa affect fuel consumption?
Targa alone does not directly affect fuel consumption; however, by allowing a more powerful motor to be installed or differing to be improved, it can indirectly affect efficiency; properly aligned with the targa can reduce water resistance and reduce consumption, while improperly installed can increase it.
Can heavy equipment, such as a battery, be attached to the target?
The battery is not recommended to be attached directly to the targa due to vibration and the risk of falling into the water. Targa is designed for navigation devices, antennas and light accessories. The battery must be in a special box on the bottom of the boat to maintain a low center of gravity and safety.
