The marketing of Ewincher began in July 2017. After 3 years of research, design and testing, the first Ewinchers took place aboard sailboats in the South of France.

Ewincher is sold all over the world. Take a look at the map of our resellers, you will surely find a partner near you. Today there are nearly 250 of them from Sydney to Portland via Helsinki and Istanbul.

Some of our reseller partners have a demo pack in store. It is possible to “borrow” the wireless electric crank from them (against a deposit for example) in order to test Ewincher in real conditions on your sailboat.

The electric winch handle, Ewincher, does not float.

The autonomy of batteries from Ewincher depend on the use of the crank and the efforts provided by it. These efforts will be greater the larger the size of the boat. To give you an idea of ​​the capabilities of the Ewincher cordless crank, here are two examples of use in real conditions on a Dufour 405:

  • 1/With the battery charged to 100%, we have was able, in 15 to 20 knots of wind, to hoist the mainsail 3 times and make 40 tacks while maneuvering the genoa.
  • 2/An 85kg crew member was able to be hoisted to the top of the mast 3 times in a row. The mast of the Dufour 405 is 14.50 meters high.

Ewincher and all the elements supplied with the pack (battery, charger, etc.) benefit from the legal guarantee of conformity provided for by the specific provisions of the Consumer Code or the guarantee against hidden defects provided for in articles 1641 et seq. civil Code. The warranty is 2 years.

The handle is developed, assembled and shipped from France, in our workshop in Hyères in the Var. Almost all of the elements that make it up come from France (Lyon) or Europe (Spain in particular). Only battery cells come from China.

In December 2022, there were 4,000 cordless cranks sold around the world. 70% of sales are made for export (outside France).

Shipping is carried out by UPS carrier. For delivery in mainland France (France), after taking charge of the package, delivery is generally assured within 3 working days. For shipments within Europe, it takes between 3 and 5 working days.

Ewincher has the IPX6 standard. This standard means that the electric crank is resistant to rain, sea gusts and other splashes. However, Ewincher will not remain waterproof if it is submerged.

Let's compare, using some data, the performance of EWINCHER with an athletic and robust teammate, at his best.

Some power data:</ p>

Wincher, in physical terms, amounts to exerting a rotating force on the handle.

This complex movement requires a particularly intense and mobilizing effort from the team member: in fact, it is well easier for the team member to resist a force by remaining immobile than to exert this same force in a rotational movement. A team member, however robust he may be, can hardly winch in full rotation from the moment when the effort required on the handle exceeds 25kg.

The maximum torque of EWINCHER, for its part, reaches more than 90 N/m, which is equivalent to a force of more than 36kg on the handle! (Find out here why it is easier to winch with EWINCHER than with a classic crank)

Some Speed ​​data:

A crew member can hardly winch at more than 60 rotations per minute consistently, even when the tension in the ends is moderate.

As soon as the tension begins to increase it becomes very difficult to maintain the same rhythm and it must slow down. On the other hand, EWINCHER's electric mode has a speed range of 0 to 100 revolutions per minute. Not only is EWINCHER faster than a teammate, but above all it always delivers the same power and does not weaken when the voltage in the ends increases. And what about the combined mode, with which EWINCHER achieves a truly unrivaled boarding speed, with up to 160 rotations per minute!

For more information on the modes of use, consult our dedicated section here.

Some endurance data:

A team member in (very) good physical condition will be able to deliver a maximum of 200 W over 30 seconds while winching constantly: beyond that, he will be incapable to provide so much energy. He will gradually slow down and show signs of fatigue. On the other hand, EWINCHER permanently delivers 230W of useful energy*, which can be mobilized at full speed, until the battery runs out: EWINCHER is incomparably more durable. For more information on battery life, see our dedicated section here. *EWINCHER has 450W of electrical energy provided by the battery. The motor and a system of gears transform this electrical energy into useful energy delivered by the outlet: it is this which turns the winch. The useful energy delivered by EWINCHER on the output tip is thus 230W.


  • Cheaper than a single electric winch
  • Offers complete assistance on all winches and all maneuvers.
  • Ewincher is a ready-to-use solution and does not require any installation work on the boat.

< ul>

  • Better control of maneuvers:
  • Ewincher allows you to always keep a feeling in the hand.
  • The Ewincher speed variator allows precise maneuvering. Most electric winches do not have a speed variator (on/off button).
  • More safety than with an electric winch thanks to both permanent control which you keep as with a classic crank (so as soon as something gets stuck you feel it immediately and can stop), but in addition Ewincher is equipped with a torque limiter very sensitive and adjustable which allows you to avoid equipment breakage.
  • Electric winches are often a nightmare for service batteries: each use, they require between 60 and 100 A. These very large and repeated discharge currents cause accelerated aging of the service batteries. Ewincher has its own battery which is designed for high discharge currents. When you recharge the Ewincher battery on your service batteries the current drawn is only 6 A. So no risk for your service batteries.
  • Installing a winch electric is not always possible. Cockpits and deck plans do not always provide the necessary space to accommodate the electric motor.


Ewincher is a teammate very powerful and very fast which has its own energy, you you just have to hold it and it does the work for you, it's a CONSIDERABLE help.

A 4 speed winch is still a winch and even though the extra gear ratios give you less instant effort to provide but by maneuvering more slowly, the overall energy you need to provide to maneuver remains the same. The interest is therefore very limited, except for racing, as we will see below.

The new ranges of 4-speed winches in overdrive versions to go faster or overdrive versions to force less, are an interesting concept but which will never be able to replace motorization if you are looking for assistance.

To better understand the interest and the limits of these winches, imagine that you are on a bike and that you have a pass to climb. Having more speeds available will allow you to better manage your effort and therefore gain a little on your speed to climb the pass. But the work you will have to do to climb this pass will remain unchanged.

If these winches, very technological, and therefore very expensive, can be interesting in competition to improve maneuvering speeds, they do not constitute, in in no case, an alternative to electrical assistance obtained by an electric winch or an electric crank which are the only assistance solutions which provide the additional energy you need to help you carry out your maneuvers.

The 4-speed winch is the competition bike, and the electric winch handle on a classic winch is the electric bike!


The basic principle of the electric genoa furling is to provide a dedicated motorization system to furl or unfurl this sail. This requires the specific installation of an electric furler which will only be used for this maneuver.

With Ewincher to furl your genoa it is extremely simple: you install the halyard of your traditional genoa furler on a winch and you use Ewincher. Quick, easy, precise and perfectly safe thanks to the permanent control of the effort, if something gets stuck, you feel it immediately, no risk of breakage.

Ewincher with a traditional furler is much better than an electric genoa furler:

  • Much cheaper than an electric furler.
  • Offers full support on all winches and maneuvers, not just the genoa.
  • Ewincher is a ready-to-use solution and requires no installation work on the boat.
  • Better control of the maneuver:
  • Ewincher allows you to always keep a feeling in the hand, so you have very good control of your maneuver.
  • </ul >
    • For the maneuver, you take Ewincher in one hand and perfectly control the winding speed thanks to the speed variator, with the other hand you manage the release of the genoa sheet. Your genoa will then be perfectly furled and easily.
    • Reinforced safety: Ewincher's integrated torque limiter and your permanent control of the maneuver prevent you from breakage.</li >
    • You remain on the basis of a perfectly proven and reliable mechanical furling system and you do not risk finding yourself in difficulty in the breeze with your electric genoa furling system falling into place. breakdown.
    • Ewincher is all in 1, you have all the motorized winches and the genoa furler becomes electric!


The specialized press is testing the different solutions for electrifying winches: Ewincher winner of the tests!

Let's take a closer look at the alternatives to the electric winch, different magazines have carried out comparative studies between electric winch handles and converted drills. Their observation is unanimous:

For the magazines Yacht, Palstek, Morgan's Cloud, Ewincher is the best solution currently available on the market.

These remarks come from a very simple observation:

The marine environment is extremely demanding and you need a crank that is comfortable and secure while being capable of delivering power constant despite high tensions.

Drills/screwdrivers are wonderful tools, which, equipped with a specific tip, allow limited assistance in operating your winches.

Find out more in details the 4 essential conditions which should help you choose your assistance tool whatever the weather:

A. The power and torque must be sufficient to be able to carry out all the maneuvers.

As you will see in the 2 test videos below, the torque available, even on the most powerful machines, is not not enough to edge a simple genoa in 11 knots of wind on a 38-footer for example.

You will have to finish your maneuver by using a manual crank because the screwdriver/drill will not give you sufficient power and that 'fine adjustment is almost impossible with this type of tool.

The first video reproduces navigation conditions on a test bench with the testing of several drill models.

The second video is a test at sea on a 38-footer.

B. During a maneuver the forces involved are quickly very significant, which is why it is essential that the principle of handling the tool associated with the position of the user (ergonomics) allows it to retain the torque transmitted both effortlessly, but also and this is the most important, without risk of injury.

As you will see in this video, these drills used on a winch in often difficult conditions can quickly become dangerous:

. As with any classic crank, locking on the winch is essential to secure the tool.

No blocking on the winch with the drill

D. The product must be able to resist water

The drill is not waterproof...particularly annoying on a boat!

In summary, with a screwdriver or an angle drill, by being extremely careful when you use it you will be able, if the weather is dry, to succeed in setting up your mainsail but this will only work if you have a small unit and a mainsail that is not too difficult to set up, otherwise it will not work. will not work. Then you will have to quickly put it dry and give up using it for other maneuvers because it is not suitable.

Ewincher perfectly meets all these requirements and much more, it can work on all winches, all maneuvers and in all weathers. It is a product which was invented to respond exclusively to all the needs of your maneuvers. As the adage says “to each his own” Ewincher does not know how to drill holes but is extraordinary to maneuver, a drill is extraordinary for drilling holes but does not know how to maneuver.
