Owning a low-pressure inflatable boat (LBBB) gives you incredible freedom of movement on the water, but the process of transporting the boat to the descent site often turns into a test of physical endurance. door-wheelUnlike fixed models, quick-removal options offer flexibility to disassemble the wheels immediately after launching, which is critical to maintaining speed and maneuverability.
The modern market of accessories for water-motor equipment offers many modifications adapted specifically for the design features of boats with a hard inflatable floor. NDMA It has a specific geometry of the transom and keel, which requires a special approach to the choice of fasteners and the length of the rod. A properly selected kit will not only make life easier for the fisherman, but also prolong the life of the boat itself, eliminating the risk of damage to the PVC material on the stones when dragging with a fiber.
In this article, we will discuss in detail how to choose the optimal model, what are the nuances of installation on boats from different manufacturers and what to look for when operating. We will touch on the technical aspects, compare materials of manufacture and provide practical recommendations based on the experience of real use in the field. Understanding these subtleties will help to avoid common mistakes and make a purchase a really useful investment in a comfortable stay.
Design features of wheels for boats with NDND
The main difference between inflatable floor boat wheels and hard bottom boat models (PVC with plywood or aluminum) is the way the rod is fastened and geometry. Since NDNDD lacks a rigid transom in the classical sense (it is often a removable plywood board or reinforced compartment), mounting is carried out directly to the water jet nozzle or through special holes in the transom board. Quick-movement The mechanisms here play a key role, as they allow you to turn the transport module into a racing configuration in seconds.
The rod of these wheels is usually L-shaped or T-shaped with an additional bend to bend around the cylinders and not touch them when moving. It is important that the metal part of the structure does not touch the PVC material under load, otherwise the abrasion of the fabric is guaranteed. To do this, manufacturers use plastic or rubber linings, and also adjust the angle of the rod.
⚠️ Warning: When installing wheels on a boat with NDND, make sure that the rod does not press on the line of gluing of the balloon and the transom board. Point pressure of the metal on the seam can lead to depressurization at the most inopportune moment.
The quick-removal mechanism is most often implemented through a stitching system or threaded fixtures that allow the wheel pair to be disconnected without removing the engine. This is especially true when the boat is already in the water and you need to remove excess resistance before you start moving. Some models involve complete dismantling along with part of the slat, which requires more thorough sealing of the installation sites.
Why does NDT require special wheels?
Boats with inflatable bottoms have a softer transom and a specific keel deflection. Standard straight rods can rest on the ground ahead of time or, conversely, do not reach the ground if the engine is not raised high enough. Specialized models take into account these geometric features.
Selection criteria: diameter, material and load capacity
When choosing an accessory, the first thing to consider is the diameter of the wheels. For sandy beaches and soft soil, models with a diameter of 250 to 300 mm and a wide rubber tire are ideal. They create less specific pressure on the ground and do not get stuck. For rocky banks and asphalt, it is better to choose wheels of a smaller diameter (200-250 mm) with a solid polyurethane tire that is not afraid of punctures.
The material of the rod and fasteners also matters. AISI 304 or AISI 316 stainless steel is the best choice for use in salt water, but it is much more expensive than anodic-coated aluminum. Aluminum alloys (such as D16T) are strong enough for freshwater bodies, but require careful care and washing after each exit to avoid corrosion.
- 🔘 Load capacity: The kit must withstand the weight of the boat, engine, battery, tank and equipment with a margin of 20-30%.
- 🔘 Tyre type: Inflatable cameras provide better coasting but risk being punched; cast tires are more reliable but stiffer.
- 🔘 Length of the rod: The height of the transom of your particular boat model (standard S, M, L, XL) should be appropriate.
Do not chase for the maximum cheapness, as thin metal can bend under the weight of a heavy four-stroke engine. transom wheels They have a lot of dynamic loads when driving on irregularities, so safety is more important than economy, and high-quality bearings in the hub will ensure easy rolling even on wet grass.
Technology of installation of different models of boats
The installation process may vary depending on the manufacturer of the boat (Flagman, Solar, Admiral, Yuzhanka, etc.), but the general principle remains similar. First of all, you need to determine the mounting points on the transomach board. Most modern models of NDNDM provide reinforced pads or holes for installation. lantern If there are no regular seats, a careful drilling of the transom board will be required, with the sealant treatment of the edges of the hole.
You'll need a standard set of tools to install: wrenches, screwdriver, marker and possibly drill. It's important to keep the markings symmetrical so that the boat doesn't sway when moving. The fasteners should be fitted with wide washers to distribute pressure on the surface of the transom and not push PVC when tightening.
☑️ Checklist before installation
Once the response bars are fixed on the transom, check the reliability of the connection by applying force in different directions. The rod should be inserted and fixed without distortion. If a system with a spring lock is used, make sure that it snaps to the end and has insurance against spontaneous opening. Incorrect installation can lead to the loss of wheels in water or damage to the transom.
⚠️ Warning: Never use bolts that are longer than the thickness of the transom board to fasten the wheels. The ends of the bolts that protrude into the boat can damage the inflatable elements of the bottom or injure passengers.
Comparative table of popular models
To make it easier to choose, we have prepared a comparison of several popular models on the market, and note that the specifications may vary slightly depending on the year of release and the specific modification.
| Model | Wheel diameter (mm) | Stock material | Type of attachment | Max. load (kg) |
|---|---|---|---|---|
| Universal 260 wheels | 260 | Aluminum D16T | Trawn invoice | 150 |
| Tranza "Standard" | 230 | Steel (painting) | The transom holes | 120 |
| Offroad 300 module. | 300 | AISI 304 Stainless Steel | Combined | 200 |
| Light version of "Econom" | 200 | Steel | Invoice | 100 |
As you can see from the table, larger diameter and stainless steel models benefit in cross-country performance and durability, but they are more expensive. Budget options are suitable for light boats with engines up to 15 hp and operating on good roads to the water. For heavy complexes with engines of 20+ hp, it is better not to save and choose the option with a margin of safety.
Lubricate the movable rod joints and locking mechanisms with silicone lubrication before each season, which will prevent jamming from getting sand and salt.
Operation and maintenance in season
Proper operation prolongs the life of any equipment. After each release, especially if you have swam on salt water or muddy rivers, the wheels must be washed with fresh water. Sand stuffed into bearings or a fixing mechanism works like an abrasive and quickly disables the knots. Regularly check the tire pressure (if they are inflatable), as the deflated wheel dramatically increases the resistance when rolling.
When transporting a boat on a trailer assembled (with wheels installed), make sure that the structure does not rub against the side of the trailer or other elements. Vibration at high speeds can weaken the fastening nuts, so it is recommended to stretch the connections before each long-distance trip. Quick-moving The mechanism also needs periodic lubrication and cleaning of dirt.
It is better to store the wheels in a dry room, in disassembled form, to relieve stress from springs and rubber elements. If the rod is made of steel, make sure that it does not have chipped paint, which can become hotbeds of corrosion during winter storage. Aluminum scratches are less critical, but oxidation can make it difficult to insert the rod into the back part.
⚠️ Warning: Do not leave the boat with the wheels installed in direct sunlight for a long time unattended. Heating metal parts can lead to thermal expansion and deformation of adjacent PVC elements.
Frequent mistakes in buying and using
One of the most common mistakes is to buy the wheels by eye without taking into account the weight of the full package. Many people forget to count the weight of a full tank, anchor, gearbox and passengers, relying only on the weight of the boat and engine. As a result, when fully loaded, the rod can bend in an arc, and the wheels can get stuck in the sand. Always take a model with a margin of carrying capacity.
Another mistake is to ignore the height of the transom. Buying a standard model for a transom 381 mm (15 inches) on a 508 mm (20 in) high-trans boat will give you wheels that will hang in the air without touching the ground. Conversely, a short rod on a low boat will hit the ground sooner than necessary, creating a dangerous lever for tipping over.
- 🚫 Ignoring the instructions: attempt to place a model not intended for NDNDM on the inflatable floor.
- 🚫 Savings on fasteners: Use of conventional bolts instead of galvanized or stainless.
- 🚫 Lack of service: The lack of lubrication leads to acidification of the moving parts in one season.
And users often forget that when you move on water, the wheels create additional resistance, and even if they are raised up, they degrade fluid dynamics and can create noise, so the rule of "low boat, remove wheels" should be an axiom for each owner.
Properly selected and installed transom wheels pay off in the first season of use, keeping your strength and health for the fishing itself, and not for carrying weights.
FAQ: Frequently asked questions
Can you install quick-removal wheels on a boat without regular holes in the transom?
Yes, it is possible. There are overhead models that are fixed to the transom plane with powerful clamps or additional slats. However, for NDND, this option is less preferable because of the risk of damage to the inflatable elements, it is safer to drill the transmuter board carefully (without touching the cylinders!) and install reinforced bushings.
Will aluminum rods withstand winter storage on the street?
Aluminum itself does not rust like steel, but it oxidizes. The problem may be the steel elements inside the mechanism (springs, pins). If you can't keep the wheels warm, be sure to remove them from the boat, wash them, dry them and pack them in a box or a dense bag with silica gel.
What is the best diameter of the wheels for fishing with a sonar?
The diameter of the wheels does not directly affect the sounder if the sensor is mounted on a transom. However, if the sensor is low, the bulky wheels can interfere with maneuvers on the shore. The optimal models are 230-250 mm in diameter, which provide good clearance, but do not have excess dimensions.
Do I need to remove the motor when installing the wheels?
In most cases, quick-removal designs allow wheels to be mounted and dismantled with a motor already attached to the transom, a major advantage over stationary models, but the first time the response slats are installed, the motor will likely have to be removed for ease of marking and drilling.
