Operation of inflatable craft, especially heavy type model NDMAMoving a powered motorized boat and battery from the car to the water can take a long time and take a lot of effort without the proper equipment, and it is to solve this logistical problem that specialized transom wheels have been created that radically change the approach to preparing for the water.
However, unlike rigid vessels, placing such equipment on a soft side or transom requires special attention to detail. PVC Or disrupt the boat's balance when launching, and understanding the nuances of attachment and operation is key to the durability of your inventory.
Design features of wheels for inflatable vessels
The main difference between wheeled systems for inflatable boats and metal boats is the way the load is fixed and distributed. NDMA It's a plywood sandwich panel, or a fully inflatable structure, and it's often impossible or undesirable to bolt hard. Engineers have developed several types of mounts that allow the trolley to be securely secured without the risk of damage to the body.
The most common option is to attach directly to the trench board with bolts that pass through special holes in the transom, which provides rigid fixation, but requires appropriate holes in the structure of the boat. sling or special brackets covering the transom, which allows you to use them on boats without regular holes under the wheels.
The wheel pair itself is usually made of durable polymers or rubber with a camera. Polymer wheels are good because they are not afraid of punctures, but can be too rigid on uneven ground. Rubber pneumatic wheels provide better coasting and cushioning, but require periodic pressure checks and carry the risk of damage to sharp stones or shells.
- 🛞 Polymer wheels are ideal for sandy beaches and smooth concrete descents, do not require maintenance.
- 💨 Pneumatic wheels – provide a soft ride on grass and stones, but require pressure control.
- ⚙️ Combined systems – use metal spokes with a rubber tire for maximum strength.
⚠️ Note: When choosing wheels, pay attention to the material of the axles. Cheap steel will quickly be coated with rust in salt water, so for sea fishing preferable. stainless steel or aluminum with high-quality anodizing.
It's also important to consider the diameter of the wheel. NDMA With powerful engines, the best choice is models with diameters of 260 mm and above. A smaller diameter will require much more effort to overcome even small irregularities of the ground, negating the whole point of acquiring an accessory.
Gender abrasion and protection methods
One of the most serious problems when installing wheels on inflatable floor boats NDMA When the wheels are folded or even decomposed, they can fit tightly into the cylinders or directly into the inflatable floor, and when you're driving over irregularities or just rolling over, you get friction that quickly erases the PVC protective layer.
The quality accessories manufacturers take this into account and complete their products with special protective linings. However, if you buy the wheels separately or use a universal model, the issue of protection becomes especially acute, ignoring this aspect can lead to expensive repairs of the boat, since puncture of the bottom in the central part is a difficult operation.
To prevent abrasion, they use plates made of hard plastic or composite materials, which are placed between the wheel axis and the balloon, taking all the mechanical load, and in some cases, owners make these protections themselves out of textolite or dense plastic, pasting them with soft material.
Use a self-adhesive PVC tape (liqui rubber) at the points of contact of the axle with the balloon to create an additional layer, even if there are plastic linings.
It is worth noting that on boats with a hard transcreant, which is an extension of the floor, the risk is less, but it is still present when the rock is strong, so checking the gaps between the wheel and the elements of the boat should be a mandatory procedure before each operation.
- 🛡️ Factory linings are the optimal solution that repeats the geometry of a particular model of a boat.
- 🧱 Homemade "textolite" spacers - a budget option that requires accurate fitting.
- 🧵 Axis winding is a temporary solution using an insulating tape or sling, ineffective for prolonged use.
Comparative table of anchorage types
The choice of installation method depends on the design of your boat and the frequency of use of the vehicle. To systematize the information and help you make the right decision, consider the main types of mounts in a comparative table.
| Type of attachment | Compatibility | Complexity of installation | Reliability |
|---|---|---|---|
| Bolt (through) | Boats with holes in the transom | Low. | High. |
| Stroopy | Any boats with a hard transcenza | Medium | Medium |
| On the transom plate. | Boats with stove installed | Low. | High. |
| Removable stops | Boats without bottom linings | High. | Medium |
Bolt mounts are considered the “gold standard” for owners who value reliability and do not plan to remove the wheels often. It eliminates backlashes and displacement when driving. Sling options are more versatile, but require regular checks of strap tension, as they can stretch or dry out in the sun.
Trans plate attachment is less common, but it's very convenient if the stove is already installed. It allows you to quickly dismantle the wheels just by unscrewing a couple of nuts. Removable stops are a compromise for those who are afraid of damaging the floor, but it requires a perfect height adjustment so that the wheels do not touch the water when driving.
For inflatable floor boats, priority No. 1 should be to protect the floor from abrasion, even at the expense of the speed of wheel dismantling.
Instructions for installing wheels yourself
The process of mounting the wheel system requires accuracy and consistency. Errors during the installation phase can cause the boat to skew during transportation or damage to the transom. Before starting work, make sure that the boat is fully pumped and standing on a level surface.
If your model is a through mount, the first thing you need to do is to mark the holes on the transom, use the template that comes with the kit, or measure the distance between the mounting holes on the wheel axle yourself, and it is important that the holes' centers match the reinforcing pads on the transmolator, if they are designed.
☑️ Preparation for installation
After marking, drill the holes with a drill of the appropriate diameter. The edges of the holes are recommended to be treated with a sealant or special glue for PVC to prevent moisture from entering the multilayer material of the transom. Then install the bolts, laying wide washers on the inside to distribute the load.
When tightening the nuts, do not make excessive efforts not to push through the material of the transom. Use engrovers or spring washers that will prevent the fastener from unscrewing from vibration. After installation, be sure to check the symmetry of the wheels relative to the diametric plane of the boat.
⚠️ Note: When drilling a transom, be sure to use a drill depth limiter so as not to damage the opposite side or internal structural elements if the transom is hollow.
For sling systems, the process is different: first, the slings are looped through special loops or enclosed by a transom, then fixed by fastexes or buckles, and it's important to make sure that the slings are not twisted and lie flat to the surface without creating local pressure points.
Operation and maintenance of the wheel system
The long life of transom wheels depends not only on the quality of their manufacture, but also on the proper care. Sea salt, sand, dirt and ultraviolet radiation all have an aggressive effect on materials. Regular cleaning after each trip to the pond will significantly extend the life of your equipment.
After use in salt water, the wheels should be thoroughly washed with fresh water. Pay special attention to the axles and bearings, as salt causes rapid corrosion of metal parts. If the wheels have pneumatic tires, check the pressure before each trip - the under-pumped wheel cushions worse and wears out faster.
Keep the wheels in a dry and dark place, long exposure to direct sunlight leads to the destruction of the structure of the rubber and the fading of the plastic, metal elements are recommended to be periodically lubricated with silicone lubricant or special compositions to protect against corrosion.
The secret to a quiet move
If the wheels start creaking when moving, lubricate the axle with graphite lubrication or apply a small amount of WD-40 to the bearings (if they are open type).
In winter, storage should be at room temperature, rubber in the cold bluffs and can crack at the first load. If you can't heat the wheels, pack them in a tight case and leave them in the garage, let them warm up before use.
- 🚿 Freshwater washing is mandatory after every contact with salt water.
- 🔧 Lubrication of moving parts is carried out at least once a season.
- ☀️ Protection from UV radiation prolongs the life of plastic and rubber at times.
Alternative solutions and life hacks of water engines
Some water-engines are not always suitable for specific operating conditions, and some water-engines are faced with situations where the standard mounts are not suitable, or the boat has a non-standard transom shape, in which case alternative methods and the wit of the owners come to the rescue.
One popular solution is to use removable wheel pairs that are mounted only during land transport and removed before launching, which reduces the boat's sailing speed and reduces the risk of catching underwater obstacles when maneuvering offshore, but this approach requires an assistant or additional mounting/dismantling time.
There are also variable geometry models that allow you to adjust the width of the track, which is especially true for narrow boats, where standard wheels can protrude beyond the dimensions and interfere with the passage through the gate or garage door, adjusting the vehicle to adapt to specific storage conditions.
Experienced anglers often modify standard mounts by adding additional support points or using soft pads from the car camera, which reduces vibration and noise when driving on gravel, the main thing is not to disturb the integrity of the load-bearing elements of the structure.
In conclusion, properly selected and installed transom wheels make the hard work of moving a boat into an easy walk. Investment as a quality accessory pays off with the saved strength and health of the back, allowing you to focus on the main thing - the enjoyment of fishing or relaxing on the water.
Can you install wheels on a boat without holes in the transom?
Yes, there are sling-mounted models or special adapters that cover the transom, but it is important to make sure that the transom is stiff enough (it has an internal reinforced insert) to withstand the load without deformation.
How often should the bearings in the wheels be changed?
With regular use and proper care (washing and lubrication), quality bearings last 3-5 seasons. Signs of wear are axle backlash, creaking or hum when driving. In models with closed bearings, replacement is less required.
Does the wheels affect the speed of the boat?
When raised, properly fitted wheels do not have a significant impact on hydrodynamics and speed, but if they favor the boat's contours too much, it can create additional drag and sailing in lateral winds.
What is the maximum weight of standard wheels?
Most PVC boats are designed to carry loads of 300 to 500 kg, enough for a boat, motor, battery, tank and crew, and overloading can cause axle deformation or mount failure.
