Modern fishing or recreation on the water is already unthinkable without automation, and one of the main assistants is the electric cat anchor. electric anchor for a boatYou're actually investing in your comfort, safety and ability to fish in any environment, without relying on the vagaries of wind or current, and this device is a radical change in the way you anchor, allowing you to instantly lock the craft or let it go on command.
The offering market is now crowded with models from budget Chinese to professional American systems. It is easy for a beginner to get confused about specifications such as traction, current consumption and the type of gearbox. In this article, we will break down all the nuances so that you can make an informed choice and not regret the money spent.
A properly selected electric winch is not just a winch, but a complex mechanism that requires proper integration into the onboard network. Errors in the selection stage can lead to a rapid discharge of the battery or even failure of the entire power system of the boat, so before buying it, you need to clearly understand the parameters of your vessel and its operating conditions.
Principle of operation and advantages of electric anchor
The basis of the design is electric motorThis is a machine that, through the gear system, transmits rotation to the drum or an asterisk. Unlike mechanical winches, here the physical effort of a person is replaced by the energy of the battery, which allows you to lift anchors weighing up to 10-15 kg with one hand by pressing a button on the remote control. The mechanism is usually protected from moisture according to the IP67 standard, which is critical for work in aggressive marine or river environments.
The main advantage is the speed and accuracy of the manipulations. You no longer have to manually poison the anchor chain, risking confusion or injury to your hands. The system allows you to put the boat exactly in the wind or current, which is especially valuable when fishing on a spinning or feeder. In addition, the electric drive eliminates the human factor when the anchor can be not fully raised or thrown too close to the board.
⚠️ Attention: Using an electric anchor requires strict battery condition monitoring. The deep discharge of the traction battery during fishing can leave you with no way to lift the anchor and no power reserve for the motor.
Modern models are equipped switch-offThese are the shafts that are triggered when the anchor reaches the upper position or when the mechanism is overloaded, which prevents the anchor shaft from winding and protects the engine from combustion. Some advanced systems even have an "anchoring" function, automatically adjusting the length of the cable to be released when the depth changes or the boat is demolished.
Key technical specifications in the selection
The first thing to look at is tractionFor PVC inflatable boats up to 3.5 meters long, a 30-40 lbs (about 14-18 kg) model is usually sufficient. For heavier aluminum or composite boats with a keel, a force of 50 lbs or higher will be required. Always take a power reserve of at least 20-30% of the minimum recommended value.
The second critical parameter is currentPower winches can consume 40 to 100 Amps in peak modes, which dictates not only the capacity of the battery, but also the cross-section of the wires you use to connect, and thin wires at this current will simply burn or cause a voltage drop, which will not give the motor the declared power.
It is also important to pay attention to the type of gearbox. Planetary gearbox It is more compact, quieter and has high efficiency, but it is more expensive and sensitive to dirt. Worm gearbox It's cheaper and more reliable in dirty environments, but it's noisier, heavier and has less resource when it's in heavy use, and it depends on your budget and how often you use it.
The table below shows the approximate correspondence of the winch traction to the type of boat:
| Type of boat | Length (m) | Recommended traction (lbs) | Anchor weight (kg) |
|---|---|---|---|
| Inflatable PVC | 3.2 | 30 lbs | 6 |
| Inflatable PVC/Aluminum | 3.2 - 4.0 | 40-55 lbs | 6-10 |
| Aluminum/Plastic glass | 4.0 - 5.5 | 60-80 lbs | 10-14 |
| boat | 5.5 | 100+ lbs | 14+ |
Overview of popular models and brands
The market leader has been an American company for many years. Minn KotaTheir series. Deckhand and Onion They are considered the benchmark of reliability, they are characterized by high-quality assembly, excellent moisture protection and the presence of a developed ecosystem of accessories, but the price of these models can be 2-3 times higher than the competition, making them a choice for those who are not accustomed to saving on comfort.
Chinese brands such as Runva, Lewmar There are many other alternatives that you can find inside the Winch case of an unknown brand, the same nodes as in expensive models, but with a simpler system of corrosion protection, and when you buy such devices, you should immediately carry out additional sealing of contacts and lubrication of the gearbox.
The Hidden Nuances of Chinese Winches
Cheap models often use plastic gears in a gearbox instead of metal gears. They work quieter, but when wedged, anchors can cut, leaving you without anchor. When buying, be sure to check the gear material or disassemble the device before the first installation.
Separately, Russian prefabricated structures, where an imported gearbox motor is installed on a domestic platform, can be interesting in terms of repairability and availability of spare parts, but the quality of assembly and fitting of units in them often “floats” from instance to instance.
When buying, pay attention to the length of the included cable. Often, regular wire (about 1.5-2 meters) is not enough to lay down to the battery in the bow of the boat. Plan in advance to buy an additional copper cable with a cross section of at least 16 mm2 (preferably 25 mm2).
Battery selection and autonomy calculation
The electric anchor is not a good fit for conventional starter car batteries, but it's designed for short-term high current output when you start the engine, but not for long-term loading. tractor Deep Cycle, which can give energy for a long time and withstand deep discharges without losing capacity.
The best choice is to AGM or GEL They are sealed, non-gas-emitting when recharging (important in a confined boat space) and have low self-discharge. Lithium (LiFePO4) batteries are becoming increasingly popular due to their light weight and huge cycle life, but their cost is still much higher, and they require a heated BMS to operate at low temperatures.
Calculating the capacity based on the average current consumption: If the winch consumes an average of 30 Amps, and you plan to raise / lower the anchor for a total of 20 minutes a day, the flow will be about 10 Ah. However, given the starting currents and the margin in case of anchor stuck, the minimum recommended capacity is 50-60 Ah. This will ensure comfortable operation for several days without recharging.
The 50% rule: Never discharge a lead-acid battery below 50% of its capacity. This will prolong its life by 2-3 times. For an AGM 60 Ah usable capacity is only 30 Ah.
Instructions for installation and connection
The installation of an electric anchor is a process that requires careful and safe operation, and the basic rule is that all connections must be as reliable and moisture-proof as possible, any spark near gasoline vapors or in water can lead to serious consequences, and poor contact can lead to heat and fire.
The installation begins with the selection of the site. The winch must be strictly horizontal, so that the anchor cable or chain descends smoothly, without distortions that can cause jamming. The fasteners must be made of stainless steel of the appropriate strength class. After installing the mechanism, we proceed to the electrical part.
☑️ Checklist before first launch
Use only copper wires to connect. Aluminum is strictly prohibited due to oxidation and low conductivity. On the plus wire, as close to the battery as possible, be sure to install safety-fuse Or a fuse of the appropriate denomination, which will save the boat from fire in case of a short circuit.
All wire connections are best soldered and further insulated with adhesive heat shrinkage. Screws in vibration and moisture on the boat do not live long. The control panel is placed in a convenient place, but so that it does not get water and the wire does not interfere with the movement on the boat.
⚠️ WARNING: When drilling holes in the transom or deck, be sure to treat the edges of the hole with anticort and use a sealant for each fastener. Water trapped inside the boat structure is washed out with great difficulty.
Maintenance and typical faults
Even the most reliable electric anchor requires attention. After every fishing trip, especially in salt water, the mechanism must be rinsed with fresh water. The salt crystallizes and destroys metal parts, and can also cause corrosion of the contacts of the control panel. Regular lubrication of moving parts with special marine lubrication will prolong the life of the device.
One of the common problems is the wear of the electric motor brushes or the oxidation of the reverse contacts. If the winch starts to work in jerks or hums but does not rotate, first check the voltage on the battery under load. If the voltage is normal, then there is a problem inside the mechanism. In cheap models, the contacts of the relay pen often lick.
Also, watch the condition of the anchor rope. The synthetic cable loses strength over time and can break at the most inopportune moment. The chain requires periodic calibration and tensile testing of the links. Regular inspection of these elements is the guarantee that you will not lose anchor along with the winch.
What if the anchor is jammed?
If the anchor is stuck between the rocks, don't try to pull it out with the power of the motor at full capacity - this can burn the windings. Try to push the boat in different directions, changing the angle of thrust. If it doesn't help, use a manual winch or drag the anchor in tow, slowly increasing tension.
Frequently Asked Questions (FAQ)
Can an electric anchor be used at a speed of more than 2 km / h?
The electric anchor is not recommended as the main means of holding on a strong current. Electric motors are designed for short-term work of lifting and lowering, rather than constant resistance to the flow of water. In the fast flow, the anchor will constantly break, which will lead to overheating of the motor and rapid discharge of the battery.
Do I need to take the winch off the boat for the winter?
It is advisable to dismantle the device and store it in a dry heated room. Although many models have moisture protection, constant exposure to sub-zero temperatures and high humidity can lead to condensation inside the case and corrosion of electronic boards. If you can not remove it, cover it with a protective case and treat the contacts with a spray-moisture suppressant.
Which battery is better: 12V or 24V?
For small and medium-sized boats (up to 55 lbs of thrust), the standard system is 12 Volts. The 24 and 36 Volt systems are used on large boats with powerful winches (from 70-80 lbs) to reduce the current in the wires and reduce their heating. For conventional PVC boats, switching to 24V makes no sense and only complicate the charging scheme.
Why does the body of the winch warm up when working?
A little heat in the electric motor body is normal, because some of the energy is inevitably converted to heat, but if the body gets so hot that it can't be touched, it's a signal that the bearings are overloaded, or the windings are jammed, and then you have to stop working immediately and let the device cool down.
Can I charge the battery without removing it from the boat?
Yes, if you install a stationary charger with adequate moisture protection on the boat or use portable charging through special sockets, the main thing is to ensure good ventilation in the battery rundoo, since hydrogen can be released when charging (especially at the end of the cycle), which is explosive.
