PPOWERFUL: 450W of electric energy combined with a 90Nm torque:

  • Ewincher can easily hoist an 110 kg crew member up the mast on a 55-footer.
  • Ewincher can easily trim a 160m2 spinnaker in 15 knots of wind.

FAST: 100 rpm in electric mode

  • Ewincher hoists the mainsail in 65 seconds on a 45-footer (Oceanis 45).

Ewincher is much more powerful, faster and more enduring than a human crew member. Here is an overview of Ewincher's performances compared to a very fit crew member.


Grinding means physically exerting rotation force on the handle. This effort is very demanding for the human body. Our arms are much more efficient when used for less complex efforts. For example, it is much easier to resist against a force while remaining static, than to exert the equivalent rotation force.
That is why, a very strong crew member finds it difficult to winch with full rotation when the effort to exert on the handle is over 25 kg. On the other hand, Ewincher's maximal torque is over 90 Nm, which is equivalent to a force of more than 36 kg on the handle.
(See here why it is easier to winch with Ewincher than with a standard handle.)


It is difficult for a crew member to constantly winch at 60 rpm, even with moderate rope tension (and so the force exerted on the handle remains under 8/10 kg). As soon as the tension increases, it becomes very difficult to maintain the same pace.

The EWINCHER electric mode has a speed range from 0 to 100 rpm, no matter the rope tension. Not only is EWINCHER faster than a crew member, but above all, it does not slow down when rope tension increases.

In combined mode (for more information on the modes of use, see our dedicated rubric here), EWINCHER provides unequalled trimming speed that can reach up to 160 rpm.


Let's consider a crew member in excellent physical condition. They will be able to produce a maximal energy ratio of 200W over 30 seconds by winching constantly; then, they will not produce as much energy. They will slow down and feel fatigue.
The major difference with Ewincher is that it continuously produces 230W of useful energy, always at full speed and until the battery is discharged. (see battery autonomy). This makes it undeniably more enduring.

* Ewincher provides 450W of electric energy supplied by the battery. The motor and a gear system transform this electric energy into useful energy produced by the end fitting. In effect, this useful energy will make the winch turn. Ewincher 's useful energy production is 230W.
