The general rule is to select a winch with a capacity rating of at least 3/4th the combined weight of your boat, motor, fuel and gear. This rule varies depending on a number of factors about your boat and where you launch it.
What gear ratio is a boat winch?
A ratio of 3:1 is used for lighter loads or for the initial winching of a heavier boat onto the trailer. Ratios of 5:1 and higher are used for heavier loads, especially once the boat is completely out of the water. An electric winch adds power and simplicity as much as it adds expense.
What is the winch on a boat called?
Traditionally, winches on ships accumulated wire or rope on the drum
those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches.
Can you use an electric winch on a boat trailer?
There are two ways to load a boat on a trailer at the ramp. There’s power loading—a practice that is prohibited at many ramps. Or you can crank it on with the trailer winch, which is hard work with a big boat. But electric trailer winches can do the loading for you.

How much do winches cost?
Winches can cost anywhere from $200 upwards of $1000.
Is a winch a force multiplier?
The winch handle is a rotary lever that is the first stage of power amplification. The ratio of drum radius-to-handle length is the first force multiplier. An 8-inch handle and a 2-inch radius drum, therefore, deliver a 4-to-1 boost in pulling power and a 4-to-1 decrease in line-hauling speed.
What is a good gear ratio for a winch?
Gear ratios range from about 150:1 to 300:1, giving the winch its pulling power. Just as with your axle gears, higher numeric ratios provide more power, but at the expense of speed. A good winch design matches the electric motor power and gear ratio to provide a desirable compromise between speed and pulling power.
How much weight can a hand winch lift?
All D-L hand winches are designed to pull their rated capacity with a force on the handle in the approximate range of 35 to 55 pounds. This means that the winch should be able to be cranked easily with one hand. If not, it is probably overloaded.
How many types of winch are there?
Winches come in seven major types: electrical winches, mechanical drum-style winches, mechanical capstan-style winches, hydraulic winches, mechanical hand-operated winches, mechanical portable winches and hybrid winches.
What are the different types of winches?
7 Essential Types of Winches
- Lever Winch. Most winches use spools, but the lever winch moves its rope with self-gripping jaws instead.
- Snubbing Winch.
- Air Winch.
- Capstan winch.
- Glider Winch.
- Mooring winch.
- Wakeskate winch.
What is a female winch?
May 19, 2016 yanira.vargas. “Wench” began as a general term for a girl or woman, and over the centuries acquired a variety of meanings, including female servant, lower-class female, and prostitute. It is mostly used today as a jokingly affectionate archaic allusion to Shakespearean ribaldry.
How do you winch a boat?
How do you winch a boat?
- Beginning from the bottom of the drum, wrap the rope around the barrel of the winch in a clockwise direction.
- Wind the rope around the drum three or four times.
- Insert the winch handle into the top of the winch and use it to wind the rope tight.
- Cleat the rope when it is wound in to keep it under tension.
How does a two speed boat winch work?
With a two speed winch, clockwise grinding is the same as the single speed, however, counter clockwise grinding will engage another set of gears which keep the drum rotating in the same direction, but at a lower the speed, thus increasing the power.
How do you power an electric winch?
Option 2: Using an Auxiliary Battery to Power the Winch
- Attach the power wire to the positive post on the winch.
- Attach the negative wire to the negative ground post on the winch.
- Run both wires from the winch to the battery compartment, avoiding hot areas and places where the wires could get pinched.
What happens to boat trailers with too little tongue weight?
If the boat trailer has too little tongue weight it will tend to make a dangerous fishtail movement. This is a swaying motion that can put the towing vehicle and boat trailer out of control, leading to an overturn, skid, or overturning.
Why should a boats gas tank never be completely filled?
It’s important to never fill the tank of your boat beyond 90% full. This leaves room for gas to expand and avoids the potential for overflow. Ensure that all air vents and valves to the gas tank are open.
How do you grease a winch on a boat trailer?

Are winches worth it?
Although a winch is a valuable tool when traveling, it is in no way a necessity for extended vehicle-based travel. Traveling off-road is more challenging without a winch, but with the right gear and practice recovering vehicles without a winch can be a simple affair.
How does a snatch block work?
Snatch blocks allow you to change the direction of a winch’s cable by off-setting the anchor point, allowing you to pull in a three-point motion. Sturdy and durable, snatch blocks are ideal for transferring loads over short distances and are commonly used in recovery situations.
Is a truck winch worth it?
If you do any off-roading at all, for work or for leisure, yes. Similarly, if you have a work truck, a winch can be a great addition. If you’re mostly an asphalt warrior though, you probably don’t need one.
Does a pulley increase pulling power?
A pulley system makes it easier to lift an object than lifting the dead weight by hand. A single pulley essentially changes the direction of the pull or force applied. When a person uses two or more pulleys in a system, then the system also multiplies the force applied besides changing its direction.
How do winch gears work?
Johnson explains it in basics: The winch motor turns a shaft connected to the first sun gear, which is engaged in a set of planetary gears that reduce the gear ratio. This first set of planetary gears transfers torque through a carrier into another sun gear, which turns the next set (or stage) of planetary gears.
What is a winch used for?
A winch is intended to be used with the pulling vehicle or anchor stationary as part of a static pull. Unspooling winch line to a stuck vehicle, throwing the unstuck vehicle in reverse and giving a yank (kinetic pull) on the stuck rig is very hard on the winches brake and drivetrain.
How do you make a winch stronger?
If you want to double the power of your winch, or if the anchor point is too close to let out enough cable for a strong pull, use a snatch block to double the line. Using a snatch block will double your load capacity and will allow you to spool out more cable to reach the maximum rating of your winch.
Can I use a winch as a hoist?
Can a winch be used as a hoist? Generally speaking, no. It is not safe to use a standard winch to lift loads up off the ground, as it wasn’t designed for this purpose and there is a risk that the load will be dropped. One of the key differences between winches and hoists lies in their braking systems.
Do winches work in both directions?
Yes, the motor in the Superwinch LT3000ATV Winch, part # SW1130220, operates in both directions (both feed out and pull in).
