Modern fishing in waters with strong currents or winds becomes a real test if your boat is not equipped with a reliable position retention system. PVC boats It is often associated with the risk of damage to cylinders, noise when lowering and the inability to quickly change the fishing site. electric motor It is not just a means of transportation, but a functional tool that replaces the anchor system.
Many fishermen still believe that electric motor allows you to keep the boat at a point without noise and splashingUnlike gasoline-powered machines, electric units operate silently and do not produce vibrations that scare away the inhabitants of the reservoir, making them ideal for delicate fishing in hard-to-reach places.
In this article, we will discuss in detail how to choose the optimal model, calculate the necessary thrust and correctly integrate the device into the design of an inflatable vessel. You will learn about the nuances of operation that will help to extend the life of the equipment and ensure your safety on the water.
The principle of operation and the advantages of using an electric motor instead of an anchor
The concept of using an electric motor as a anchorage It's based on the motor's ability to generate constant thrust against the current or wind, which allows the boat to stay at a given point without physical contact with the bottom, and it's particularly effective at great depths where the length of the anchor shaft could be a problem, or on a rocky bottom where there's a high risk of hooking.
The main advantage is mobility. If the stick stops or the weather changes, you don't have to waste time sampling the anchor, unwinding the rope, and waiting for the boat to blow off by the wind, just change the thrust vector or add gas to move to a new position instantly, saving you valuable fishing time.
In addition, the absence of heavy metal cargo inside the cylinder or hanging from the side reduces the risk of puncture. PVC materialA cat anchor or plow can damage the fabric when rolled heavily, whereas an electric motor screw, even when accidentally touching the ground, usually has protection or is made of composite materials that are safe for the housing.
⚠️ Note: Using an electric motor in the "anchor" mode requires constant charge monitoring batteryDon't rely on indicators blindly, as under load, the voltage can drop faster than the rest voltmeter indicates.
It is important to note that modern models are often equipped with a function. point-holding In this case, the electronics adjust the engine to compensate for the boat's demolition, which removes the need for the angler to constantly monitor the position of the vessel manually.
Criteria for choosing an electric motor to hold on to a point
Choosing the right model is a balance between power, weight and functionality. To operate effectively as an anchor, the motor must have sufficient thrust to withstand not only the current, but also the wind pressure on the sailing of a fishing boat with fishing gear.
The first parameter to look at is maximum thrust, measured in pounds (lbs) or kilograms. For small inflatable boats up to 3 meters long, a 30-40 lbs motor is usually enough. However, if you plan to fish on fast-flowing rivers, this figure should be increased.
- 🚤 Boat thrust and size: Keep in mind that holding on to a point requires less power than moving, but a 20-30% margin is required.
- 🔋 Control type: Manual control requires a constant presence at the hummel, while foot or remote control (via remote control / smartphone) leaves hands free for tackles.
- ⚓ Availability of GPS module: Models with function Spot-Lock or analogues automatically hold the coordinates, which is the highest form of implementation of the function of "anchor".
The type of propeller is also critical. Two-blade propellers create less noise and vibration, which is important for fishing, but three-blade propellers provide smoother running and better efficiency at low revs. Three-blade composites are preferred for position holding mode.
Some engines designed specifically for inflatable boats have special mounts or transom slabs that distribute the load on the boat. PVCpreventing its deformation.
Table of conformity of motor traction and operating conditions
In order not to make a mistake with the choice, you need to correlate the technical specifications of the engine with the real fishing conditions. Below is a table that will help you navigate the desired class of thrust depending on the size of the boat and external factors.
| Size of PVC boat | Total weight (boat + cargo) | Conditions (quiet water) | Conditions (current/wind) |
|---|---|---|---|
| 3.0m | 250 kg | 30 lbs (13.6 kg) | 40-45 lbs (18-20 kg) |
| 3.2. - 3.6 m | 250 - 400 kg | 45-55 lbs (20-25 kg) | 60-70 lbs (27-32 kg) |
| 3.8. to 4.2 m | 400 - 600 kg | 70-80 lbs (32-36 kg) | 85+ lbs (38+ kg) |
| 4.5 m or more | 600+ kg | 85-100 lbs (38-45 kg) | 100+ lbs (45+ kg) |
The data in the table is indicative. The actual power requirement may increase if the boat is high sailing or if fishing is in the fairway with a strong bottom current.
It is also worth considering that the operation of the motor at the limit of possibilities quickly discharges batteryThe use of a motor with a reserve of thrust will allow you to work at medium speeds, which is more economical and quieter, and this is especially important for multi-day trips without the possibility of recharging.
To save battery life in anchor mode, try to position the boat with your nose against the current or wind, which reduces sailing and drag, reducing the load on the engine.
Features of installation of electric motor on inflatable boats
Installation of the electric motor PVC boat It requires careful preparation, because inflatable tubes do not have the stiffness of the transom of the boat. The main task is to create a reliable support that will not damage the material and will withstand the propeller's reactive thrust.
The most common option is to use a hinged transom, a rigid plate (usually made of plywood or dural) that attaches to the cylinders or stringers of the boat, and the motor is attached to this transom, and it's important to make sure that the transom has the right angle of inclination so that the deadwell is submerged to the required depth, but does not touch the bottom.
- 🛠️ Strubbine anchorage: Standard strubcines can damage the soft transucine. Use expansion plates or special adapters to distribute pressure.
- ⚖️ Balancing: The motor and the battery shift the center of gravity, so position them so that the bow of the boat does not gaze excessively, or the handling will deteriorate.
- 🔌 Wire fixation: All wires shall be securely secured and shall not rub against cylinders or sharp edges of structural elements.
For boats without a hard transom, there are special suspension systems attached directly to the cylinders, which are frames that cover cylinders. PVC It may be slightly deformed under load.
⚠️ Warning: Never attach the motor directly to a soft cylinder without a rigid spacer. Vibration and thrust will instantly wipe the material, leading to a water emergency.
The correct installation of the diewell is the key to effective operation. The screw should be immersed in water to a depth that excludes air capture (cavitation), but not too deep, so as not to increase the resistance of the water. The optimal position is when the screw is below the bottom level by 15-20 cm.
Energy supply: calculation of autonomy and choice of battery
The heart of your retention system is the battery pack. Unlike starter batteries, electric motors need traction batteries that can give off power in low currents for a long time, and using a car battery can cause it to fail quickly.
To calculate the required running time, you need to know the current consumed by the motor at operating speeds. Usually manufacturers specify this information in the specification. For example, if the motor consumes 20 Amps when holding the point, and your battery capacity is 100 AH, then theoretically it will last 5 hours. However, you should take into account the Paykert coefficient and do not discharge the battery more than 50-70%.
☑️ Checking the power system before exit
Modern. Lithium-Iron-Phosphate (LiFePO4) They're becoming the de facto standard for electric motors, they're 2-3 times lighter than lead, they're more efficient, they're not afraid of deep discharge, and despite the higher initial cost, they pay off their lifetime in charge-discharge cycles.
It is important to correctly calculate the length of the cable from the battery to the motor. Too thin or long wire will lead to a drop in voltage and loss of power. Use copper wires with the cross section recommended by the motor manufacturer, usually at least 6-10 mm2 for high-power models.
How to extend the life of the battery?
Store the battery at +10...+20°C. Do not leave it completely discharged for a long time. After each fishing, recharge the battery, even if it is not completely discharged. For LiFePO4, use only special chargers with the appropriate charge profile.
Keep in mind that you have to protect yourself from moisture. Battery and motor contacts should be securely insulated, because salt water and splashes cause rapid corrosion. Use special spray preservatives for electrical contacts.
Fishing tactics and safety when using an electric motor
Using an electric motor as an anchor changes fishing tactics, and you get the ability to capture complex areas, like pools, snares, areas under overhanging trees, where a traditional anchor is useless or dangerous, but this requires increased concentration and safety.
When fishing on the current, always keep your nose against the flow, which ensures the most stable position of the boat, and if the current changes direction, you need to react quickly, turning the engine so that the boat does not turn on the side, which can lead to a rollover.
- 🎣 Handling: When active, make sure that the line or cord does not fall into the working screw. This can lead to a break in the tackle and damage to the deadwell.
- 🌊 Excitement: At high wavelengths, anchor mode may be inefficient, the boat will be rocked very hard, and the engine will run idle, consuming charge.
- 🚫 No-go zones: Do not use an electric motor in places with abundant water vegetation that can wind on the screw and block it.
An important aspect is the presence of a safety phasing. Even with an electric motor, it is advisable to have a light cat anchor on a short phasing on the fast flow as a backup option in case of a complete battery discharge or engine failure.
The electric motor gives the tactical advantage of quietness and maneuverability, but requires a disciplined attitude to battery charge and environmental control.
⚠️ WARNING: When using an electric motor at night or in poor visibility, be sure to have running lights powered from a separate source or main battery via a fuse.
Frequently Asked Questions (FAQ)
Can an electric motor be used at full power to keep the boat on a strong current?
Full-power use is possible, but not recommended for long-term use, which leads to overheating of the engine windings and rapid discharge of the battery, preferably a motor with a thrust reserve to operate at 60-70% of the power, or use the anchor in extreme current conditions.
Which battery is better to choose: AGM, GEL or Lithium?
Lithium (LiFePO4) batteries are the best choice for fishing because of their light weight and the possibility of deep discharge. AGM and GEL are good alternatives if the budget is limited, but they are significantly heavier and require a more careful attitude to depth of discharge.
Do I need to clean the electric motor before each exit?
Permanent lubrication is not required, as most modern motors have sealed oils, but after every fishing, especially in salt water, you need to wipe the shaft and deadwell with clean water and apply silicone lubrication to prevent corrosion and oxidation of contacts.
What if the engine stopped pulling and the engine stopped pulling?
You need to immediately shut down the engine. You take the deadwell out of the water and you can manually clean the screw of vegetation. Attempting to gas the grass will only overload and melt the insulation of the wires.
Are electric motors compatible with transom-free boats?
Yes, they are compatible. For these boats, there are special attachments and frames that are attached to cylinders, the main thing is to ensure that the mounting is rigid so that the engine does not hang around and damage the PVC material.
