Loading a Boat with an Electric Trailer Winch

Electric trailer winch

Loading your boat is easy with an electric trailer winch.

Loading and unloading your boat with an electric trailer winch is fast and easy. Just follow the instructions below.

Loading Your Boat with an Electric Winch

  1. Connect the trailer winch to the power source. Connect the remote control (if using a corded remote).
  2. Line up the trailer and boat to get ready for loading.
  3. Release the clutch on the electric winch so that you can freespool the cable out.
  4. Spool out enough cable to reach the boat. (If the cable is difficult to freespool, you can try powering out with the motor for a few seconds, with the clutch fully released. Then continue freespooling.)
  5. Attach the winch hook to the bow eye on your boat.
  6. Engage the clutch to set the brake. Be careful not to overtighten the clutch.
  7. Get clear of the cable, electric winch, and boat. Make sure all bystanders are out of harm’s way in case anything should go wrong.
  8. Power in the cable until the boat is fully loaded and the boat juts up against the bow stop.
  9. Disconnect the remote control (if using a corded remote).
  10. Secure the boat to the trailer.

Unloading Your Boat with an Electric Winch

  1. If not already connected, attach the winch hook to the bow eye on your boat.
  2. Connect the electric winch to the power source. Plug in the remote control (if corded).
  3. Remove the boat tie downs and the chains that secure the boat and trailer, leaving only the winch hook connected to the bow eye.
  4. Disengage the clutch so that the cable is allowed to freespool.
  5. Let the boat slide off the trailer into the water. If the boat slides down too fast, you can tighten the clutch slightly to slow down the boat.
  6. After the boat is in the water, release the winch hook from the bow eye.
  7. Engage the clutch so that the brake is set.
  8. Keeping a steady amount of tension on the winch cable, power in the cable with the winch remote. Be careful not to let your fingers get too close to the winch.
  9. Secure the winch hook to prevent accidental damage.
  10. Unplug the remote control and store it in a safe, dry location.

Choosing an Electric Trailer Winch

An electric trailer winch with a strap is easier on your hands.

An electric trailer winch makes it a lot easier to load boats, personal watercraft, vehicles, and other cargo onto a trailer. Here are a few tips on choosing an electric winch for your trailer.

Winch Power

One of the most important considerations when choosing an electric trailer winch is the maximum load rating. If the winch doesn’t have enough power to pull the load you want to move, it won’t do you any good. The actual winch capacity depends on whether you’re pulling a rolling load, a floating load, or a dead weight load. If you’re pulling out an old car that’s been sitting for years with the tires sunk down in the mud, you’re going to need a lot more power than if you’re loading a boat in the water. The greater the amount of friction or suction, the more winch power you will need to pull the load.

Winch Strap or Cable

Some electric trailer winches use steel cable, while others use a strap. A strap is easier on your hands (no frayed wires) and won’t bind up inside the drum. Steel cable is stronger for use with pulling heavier loads. Since cable is smaller than a strap, you can fit more cable on the spool for longer line length. Steel cable can also be used for a double line pull, which allows you to pull heavy loads above the single-line rated capacity of your trailer winch.

Accessories

Some of the winch accessories that come in handy are lights (for nighttime loading), a backup hand crank (in case the power fails), and a wireless remote control (for safe distance). Not all trailer winches come standard with these luxuries.

Electric Trailer Winches: Strap or Cable?

Steel cable is used for large capacity trailer winches.

Most electric trailer winches come with nylon strap or steel cable. The main differences between them are strength, length, and ease of handling.

Strength

Steel cable is used to handle heavier trailer winch loads because of its strength and double line capacity. A strap can’t be doubled, but a steel cable can pull almost twice its weight if doubled. This is an advantage for heavy boats and steep trailer angles.

Length

Since cable is thinner and smaller than a nylon strap, you can fit more length of cable on the spool than you could fit with a strap. If you need more line to pull in your boat, an electric trailer winch with steel cable is the better option for you. If line length doesn’t matter, then either cable or a strap is an option.

Ease of Handling

A nylon strap won’t pinch, fray, or get buried in the spool under load. It’s easy on your hands, since there are no sharp burrs to worry about. If the strap gets cut or nicked, it won’t cut your hands, although it will reduce the effective working load. Cable, on the other hand, tends to fray slightly, and the sharp wires and burrs can be painful if you are not careful. Steel cable requires greater care in handling (wear thick leather gloves) and must be spooled in even rows on the winch drum to prevent nesting.

How to Load a Boat on a Trailer with an Electric Winch

Loading your boat can be a chore, but not when you use an electric trailer winch. You can easily load a boat on your own without any help. See the steps below for how to load a boat using an electric winch.

  1. Place the vehicle’s transmission in “Park.” Set the emergency brake and block the wheels with suitable chocks to keep the vehicle from rolling.
    NOTE: You may wish to keep the vehicle’s engine running to continually recharge the battery while using the boat winch. However, use extreme caution when working around a vehicle with its engine running.

  3. Pull out the steel cable to the desired length by pushing the “Power Out” button on the remote. Leave at least four turns of steel cable on the winch spool to prevent the cable from pulling completely out of the winch.
  4. a
  5. Hook on to the boat or other object to be moved by securing the winch hook to a pulling point, tow strap, or chain. Do not wrap the steel cable around an object and hook it back on itself. This can kink or fray the steel cable. Only attach the winch hook to an approved tow point that is able to withstand the force of the pull without causing damage to the boat or object being pulled.
  6. a
  7. Clear the area of bystanders. Never allow anyone to stand near the steel cable or in line with the steel cable behind the winch while it is under power. If the steel cable should slip or break, it can suddenly whip back towards the winch, causing a hazard for anyone in the area.
  8. a
  9. Stand clear of the cable and winch. When it is safe to do so, press the “Power In” button on the remote to power in the steel cable and pull the boat as desired.
  10. a
  11. When the boat is within a few feet of the trailer jack, pulse the “Power In” button on the remote until the boat is fully loaded.
  12. a
  13. Secure the boat with an approved tie down strap or chain. Do not rely on the electric boat winch to hold the boat in place while trailering.
  14. a
  15. Unplug the winch remote before trailering. Store the remote in a safe, dry location.

Now your boat is loaded on the trailer! When you are finished loading the boat, make sure you secure it properly to the trailer, following the manufacturer’s instructions. Double check all straps, chains, etc. before trailering to make sure the boat is secure.

Tips for Safely Operating Your Boat Trailer Winch

Electric trailer winches make loading your boat quick and easy.

Electric boat trailer winchesElectric boat trailer winches are designed for easy loading and unloading of your boat. A hand crank requires greater strength and effort and, depending on the weight of your boat, can make loading your boat more difficult than it needs to be. They also leave you with a free hand to guide the boat as needed.

If you’re in the market for an electric boat winch, look for one that can handle the weight of your boat, including fuel and gear. Since your boat is in the water as you load, the trailer winch can handle a greater load capacity than its rated line pull capacity. The pull capacity of your winch should be at least three-quarters of the combined weight of your boat, motor, fuel, and gear. When you estimate the required load capacity of your trailer winch, keep in mind that the loading incline and other factors can also increase the load on your winch.

Even though you might be tempted to rely on your winch to secure your boat to the trailer, an electric marine winch is not designed to act as a tie-down. After loading your boat, unhook the cable from the boat and use separate tie-downs, such as racket straps, to secure your boat to the trailer.

Some electric trailer winches include a backup hand crank in case of winch failure, so even if your electric winch stops working, you can still load the boat manually.

Regularly inspect your winch line for damage or wear. Replace the cable if it shows signs of deterioration. A cable that breaks under load can lash through the air, creating a dangerous situation for anyone in its way. Some electric boat winches include a corded or wireless remote that allows the operator to stand clear of the winch in case of cable failure.

If you wind the cable back into the shaft when it’s not under load, keep the line taut to prevent the cable from kinking or tangling inside the winch housing. Also note that a trailer winch is not designed for use as a hoist or lift. It is only approved for horizontal pulling or for pulling on a slight incline.
