SailForce Electric Winches
Smart Electric Winch

Ewincher presents SailForce, a new generation of winch motorization combined with the quality of HUTTON winches. SailForce is a new electric winch that pushes the limits of conventional solutions.

Maneuver control takes on new meaning with:

The remarkably fast and precise variable speed on both winch speeds.

Everything is there: precision, speed + 25% and real-time control of the tension of the maneuvered rope.

Unrivaled safety thanks to an extremely sensitive tension limiter that can be configured for each maneuver.

Not to mention an energy saving of 50%!


Here is SailForce, our “Smart Electric Winch”.


SailForce is available in sizes 40, 45, 52, 57 and 70. A real patented technological breakthrough that revolutionizes motorization of the winch.

    Safety: Tension Limiter.

    order

    We have developed an ultra-sensitive tension limiter in order to protect the boat's equipment against potential damage. Electric winches, due to their high power, present a risk of breaking certain equipment, for example when a reef becomes blocked or a rope gets stuck in a pulley. Our tension limiter is designed to detect these scenarios. Find out how it works below.

    Principle.

    The SailForce electric winch calculates the real-time tension on the line. Users can customize tension limits, ranging from 10 kg to the maximum tension capacity of the winch (which varies depending on the winch's size, from 800 kg for a size 40 winch to 1600 kg for a size 70 winch).

    When the tension on the line reaches the defined limit, the motor stops instantly.


    Operation.

    tenion limiter electric winch

    Tensions on the lines vary significantly depending on the maneuver. To configure effective and situation-specific tension limits, it is essential to be able to set specific tension limits for each maneuver.

    This is why we have introduced "Maneuver Programs" (1).
    Each program stores its unique tension limits.

    Switching from one program to another (2) is simple and quick; just press one of the keyboard arrows.

    Each "Maneuver Program" offers two independent tension limits:

    -  Tension limit for high speed. (3)

    -  Tension limit for low speed. (4)



    Fully Customizable.

    To meet the specific needs of each sailboat.

    Why is it essential to have different tension limits?


    Most maneuvers typically have two stages:

    1.
    The initial phase requiring speed with relatively low tension (e.g., hoisting the mainsail to the masthead). High winch speed, or speed 1, is generally used at this stage.

    2.
    The second stage typically involves fine-tuning the sails with higher tension (e.g., trimming or tensioning the mainsail halyard once it's at the masthead). This is when low winch speed, or speed 2, is employed.


    Detecting an anomaly during the first phase means identifying a relatively low tension anomaly. In contrast, detecting an anomaly during the second phase entails recognizing higher tension. This is why it is essential to have two distinct tension limits for each winch speed.


    Example: Hoisting the Mainsail.



    Stage 1: Hoisting the mainsail using high speed.

    Hoisting the mainsail requires a tension of 100 to 200 kg on the halyard. A typical anomaly at this stage is a jammed reef or a slider getting stuck.

    To optimally use the tension limiter at this stage, simply set the tension limit for the winch's high speed (speed 1) between 100 and 200 kg, depending on the boat (size and configuration).

    This ensures safe mainsail hoisting: if a reef is jammed or a slider gets stuck, the tension on the line will abruptly increase and reach the tension limit. The motor will immediately stop, preventing equipment damage.



    Stage 2: Trimming the mainsail with low speed.

    Depending on the sailboat, the required tension varies between 450 and 800 kg. Therefore, you need to set the tension limit for the winch's low speed to a sufficient tension level to complete the maneuver.


    Once the limits are set, you only need to select the "Hoisting the Mainsail" program:

       -  1:  Press the high speed until you reach the tension limit.

    If the mainsail is hoisted without anomalies (jammed reef or other issues):

       -  2:  Switch to low speed until you reach the tension limit.


    Your mainsail is hoisted and adjusted.

    Maximum current consumed on service batteries

    Conventional electric winches (12V brushed motors) have two major flaws in terms of their electrical consumption: they consume a lot (too much) energy; and they require currents of such intensity that the longevity of the service batteries can easily be compromised.

    We set ourselves a challenge when designing our electric winch: we wanted SailForce to have a reasonable electricity consumption, similar to most on-board equipment. We had to make some technological choices, but we got there.

    Our result: SailForce consumes 2 to 3 times less energy than conventional electric winches, and the currents it draws on the service batteries are similar to those of the on-board refrigerator.
    Our innovation is largely based on the addition of a Lithium battery which supplies our motor with 30 V DC current. Two elements should be remembered regarding the electricity consumption of our electric winch: it consumes 50% less energy compared to conventional electric winches.

    Energy efficiency:   65%   vs   35% for conventional engines.

    Sailforce is a latest generation high efficiency engine that combines 3 key technological choices to offer exceptional performance compared to current conventional engines:


    A 1250 W brushless motor instead of 12V DC motors.

    A Lithium battery supplying the motor with 30 V DC (instead of 12 VDC for electric winch motors conventional). Our Lithium battery charges on the boat's 12V.

    A gear reducer and an angular gearbox with much higher efficiency than the screw and wheel system classic engines.

    The result? An energy efficiency of 65%, compared to less than 35% for conventional electric winches. That's half the energy consumed for the same work.

    Sailforce preserves
    the service batteries of your sailboat

    Only 6A preserved by the boat battery


    The energy of the SailForce electric motor is provided by its independent battery pack (30 V Li Ion compact pack).

    This battery pack is supplied with your SailForce winch, and you can place it wherever you want.
    This pack includes a battery charger powered by 12 VDC.

    As soon as you are not using your electric winch, the SailForce battery recharges automatically and gently from the 12V network of your service batteries, consuming only 6A.

    This low current consumption completely preserves your service batteries.

    SailForce consumes 2 to 3 times less energy
    than conventional engines at maximum load

    The table below gives for SailForce and for conventional engine solutions with one or two motorized speeds:

    The maximum load per winch size (in kg)

    The current intensity on the battery (12 V service battery or 30V SailForce battery) for tow the maximum load (in A)

    The electrical energy consumption in Wh to tow the maximum load on 1m

    Conventional solutions require between 130 and 380 A, accelerating the aging of your service batteries.

    The data in this table comes, on the one hand, from performance tests carried out on SailForce, and on the other hand, from public performance data on the various conventional technologies :

    BSM (Battery Safety Management)

    Device which permanently monitors the proper functioning of Lithium batteries (temperature, charge, Voltage, etc.). Turns off the battery in the event of an anomaly.

    Safety fuse

    In the very unlikely event of BSM failure, a 50A fuse ensures system safety (battery current in normal operation is 45A).

    A Brushless motor is much safer
    than a traditional motor!

    Traditional motor: it just needs to be connected to the power for it to start. Any mechanical anomaly of the switches or contactors may cause the motor to start immediately.

    Brushless motor: to be able to function, it must be controlled by an electronic card which must constantly send it series of extremely precise orders. An anomaly in the electrical power supply does not allow these messages to be executed correctly, and therefore the engine to operate and the electric winch to start.
