Every inflatable boat owner is faced with the need to upgrade their standard configuration, often with a standard hinged transcent that comes with a standardized, standardized, and highly-confidentialed design. PVCIt's not enough to have a powerful motor or a specific piece of equipment, and that's when the remote transom comes on the stage, a design that allows the engine to move further away from the stern, increasing the usable space inside the cockpit.
This solution is not universal and has its own technical features that directly affect the behavior of the vessel on the water. Hydrodynamics The changes in boats are drastic, which can both improve speed and create serious handling problems, and understanding the nuances before buying or manufacturing such a piece is critical for safety.
In this article, we will look at why a remote transom is needed, what hidden risks it poses, and who should really consider installing it, and we will analyze the effects of shifting the center of gravity, changing the differential, and the practical benefits for anglers and tourists. Engineering approach This issue will help to avoid the typical mistakes made by beginners when tuning their boats.
Design features and purpose of the remote transom
The main idea of the remote transom is to shift the attachment point. outboard And this can be done structurally as a separate stainless steel or aluminum frame, or as an elongated wooden board with powerful brackets, and the main requirement here is to provide stiffness comparable to the standard transomb so that the vibrations of the engine do not destroy the structure.
These devices are often used to install additional equipment, such as downriggersBut the main goal is often to make room in the cockpit, and when the motor is moved back, the occupants have more legroom and equipment, which is especially true in the case of the occupants. small-boat.
It's important to understand that the snag is not just a stick with a hole, but a complex element that affects the balancing. shoulderIf the standard transom is based on the entire width of the stern, the remote structure often has support points that require special attention to load distribution.
⚠️ Attention: The use of a remote transc with a motor above the manufacturer's recommended boat may cause the seams of the transcloth paste to rupture or deformation of the cylinders due to increased pressure lever.
Key advantages of modernization of the feed part
The first and most obvious advantage is the increase in usable volume inside the boat. NDMA Every centimeter counts, and the motor's removal allows you to comfortably place fishing boxes, a tent, or just stretch your legs without hitting the engine's lower unit. comfort Long stay on the water.
The second important advantage is the possibility of installing a second engine. For trolling enthusiasts, the remote transom often serves as the basis for mounting a low-power electric motor or a gasoline two-stroke engine with a capacity of 2-3 hp. electric - for silent wiring of baits, without taking up the main seat.
Also worth noting is the convenience of service. When the motor is overboard, access to the engine is available. squirt-board It's easy to check the leakyness of the sticker, to dry the cockpit, or to get things out of the kunduk without taking off the engine every time, and this is especially valuable when you're camping on the water, where the boat is often used as a warehouse.
- 🚀 Significantly free up space in the cockpit for passengers and cargo.
- ⚓ The ability to install a second engine for trolling without losing space.
- 🔧 Simplified access to the internal elements of the feed and transom pasting.
- 🎣 Convenience of placement of additional attachments (rod holders, sonar).
Disadvantages and risks of using remote structures
Despite the obvious advantages, there is a downside to the coin. centre-upShifting the heavy motor back up the bow of the vessel, which in planing can lead to "goat" or burrowing in the wave in the headwind. The boat becomes more sensitive to the distribution of weight of passengers: if everyone sits on the nose, the stern will linger even more, and it will be almost impossible to get to the plane.
The second critical point is sailing and wind loading, and the remote transom creates an extra area that catches the wind, and when you're side wind or in a parking lot, the boat can lag to the wave faster than usual. weight-bearing on the stern, which for light inflatable models can be significant, especially when transported on the roof of the car.
And you also have to keep in mind the reliability of the mount, and any extra prefabricated structure is a potentially weak link. ICE It's capable of unwinding bolts if they're not fixed correctly, and unlike a monolithic translat, a remote one requires constant monitoring of the condition of the fastener and no backlashes in the nodes.
⚠️ Note: When installing a remote transom, it is strictly forbidden to exceed the maximum power of the motor indicated in the boat's passport, even if the design of the transom seems very durable - the risk comes from the load on the cylinders.
Impact on speed
Shifting the motor back increases the length of the current waterline, which theoretically can add 1-2 km / h to the maximum speed, but only with the correct alignment.
Impact on driving performance and handling
Hydrodynamics is a precise science. When you install a pull-out transom, you actually change the point of application of traction. The engine, when you put it back, starts to work with a large shoulder, which can improve the planing output when you load it properly, but it can make it worse. course-stabilityThe boat becomes more "frisky," requiring more frequent course adjustments, especially at high speeds.
Special attention should be paid to the behavior on the wave. When the oncoming wave, the raised nose of the boat (because of the displacement of the weight of the engine backwards) can play a cruel joke. Instead of cutting the wave, the nose will slap it on it, splashing the cockpit and slowing down. battery And the passengers are closer to the nose, which is not always convenient.
But there's a positive side to it, and in quiet water, with proper balancing, the remote transom allows you to lower it. slab-stove This is especially useful for flat-bottomed boats that tend to cavitate the screw when cornered sharply, and a properly chosen transom angle can compensate for the shortcomings of the standard design.
| Parameter | The regular transnet | Takeaway transom |
|---|---|---|
| Centrification | Balanced | Stern-shifted |
| Position in the cockpit | Motor-restricted. | Freely. |
| Sailing | Minimum | Elevated |
| Installation of the 2nd engine | Impossible/Difficult | Easily implemented |
Materials and reliability requirements
The choice of material for the takeaway transom is a matter of life and death. stainless steel AISI 304 or 316, which does not rust in salt water, withstands high loads and has an aesthetic appearance, but the weight of this design can be excessive for light boats, so often use aluminium with anode coating or high-strength alloys. dural.
Wooden tar-coated transes, coated with sea lacquer or epoxy, are rarer, but have the right to life. The main thing is to ensure the full sealability of the wood, since constant contact with water and vibration will quickly destroy even the best quality varnish. Inside the tree should not remain voids where water can leak and freeze in winter, split the material.
The attachment of the remote transom to the boat should be carried out through regular slings of the transmutation tab or special reinforced ribbons. The use of simple carbines or ropes is unacceptable. All bolt joints should be made of stainless using growers or fixing nuts so that vibration does not weaken the structure during movement.
When buying a finished takeaway transom, pay attention to the presence of rubber or plastic linings in the places of contact of metal with cylinders - this will prevent rubbing of PVC fabric.
Practical recommendations for installation and operation
The installation process requires precision and technology, and you first need to mark the mounting points, making sure that they fall on the reinforced sections of the transom tab, then you need to fix the main frame, check that there are no distortions, the motor is hung only after the final fixation of all the elements. elbow (carving fixer) on all threaded joints.
In operation, owners of such boats are advised to regularly check the condition of the attachment points. After each release to the water, especially if there was a wave, it is worth visually assessing whether there were scuffs on the cylinders in contact with transom fasteners. depressurization.
Storage of a boat with a remote transcenium often requires its dismantling if the structure is not foldable. Keeping the boat inflated with a heavy transcension installed is not recommended, as this creates a constant strain in the PVC tissues. It is better to remove the structure or keep the boat deflated to extend the life of the boat. polymeric.
☑️ Checking before getting on the water
⚠️ Warning: Never try to start the motor if the remote transom has even a minimal backlash relative to the boat hull - this can lead to instantaneous destruction of the mounting point.
Comparison and selection of the optimal solution
The decision to install a remote transom should be considered. If your main goal is fishing alone or together in calm waters, and you critically lack legroom or install a second motor, then this is a great option. upgradeIt turns a regular boat into a specialized tool for trolling or relaxing.
However, if you plan to actively walk on big water, get into stormy conditions or carry a full set of passengers, it is better to abandon this idea. seaworthiness And the benefits of space outweigh the benefits of space, and safety should always be the number one priority.
Ultimately, the remote transom is a compromise, a tool for solving specific problems, not a necessary element of tuning, and with the right approach to the selection of materials and installation, it will last for many years, enjoying comfort. shifting the center of gravity back more than 15-20 cm from the normal position requires mandatory running tests with a gradual increase in speed.
A remote snag is a great way to increase the comfort and functionality of a fishing boat, but it requires strict control of the centering and avoiding extreme speeds.
Frequently Asked Questions (FAQ)
Can I make a remote transom myself from a profile pipe?
Yes, it's possible if you use stainless steel or high-quality aluminum. However, it's important to correctly calculate the thickness of the walls and use professional argon welding. Homemade structures from a conventional black pipe will quickly rust and may not withstand the load, so it's better to use ready-made certified solutions or contact professionals.
Will fuel consumption increase when using a remote transducer?
The remote transom does not directly increase fuel consumption by itself, but changing the boat's alignment can cause the engine to run in suboptimal mode (for example, the boat does not go on the plane or goes with a buried nose), which indirectly leads to overconsumption. If properly balanced, the flow can even be reduced by improving hydrodynamics.
Will a snail be suitable for inflatable floor boats (NDBs)?
For NDND boats, the installation of a remote transom is possible, but it requires special care. The pressure in the inflatable floor and cylinders should be maximum. Often, these boats use special models of transmuters with a wide support on the stern beam to distribute the load and not damage the structure of the bottom.
Do I need to register a boat with a remote transom in GIMS?
The installation of a remote transom does not require re-registration of the vessel, unless the engine power changes above the thresholds (usually 8 hp or 10 hp depending on the year of manufacture of the boat and the legislation) or the weight of the equipped boat. However, changes in design should not contradict the boat's passport. If the transom is part of a certified tuning, problems usually do not arise.
