  Because an electric winch must be able to respond to all maneuvers.

  

  Best performance on the market.

  To evaluate the performance of an electric winch, we measure the speed of the winch (Line Speed) for all a series of tensions on the rope (Line Load), from 0 kg up to the maximum tension that the winch can tow (Maximum Line Load).

  For optimal viewing, turn your phone in landscape mode.

  

  We compared these performances to those of conventional electric winches (12V DC without variable speed) on the market.

  The performance of SailForce is based on our own tests, that of other electric winches on the market is based on public data provided by their manufacturers.

  Discover below some explanations to help read these performances:

  Variable Speeds vs. Non-Adjustable Speed: Understanding the representation differences (Surface vs. Curve)

  The fundamental difference between the representation of SailForce performance (in the form of a surface) and that of existing solutions on the market (presented in the form of curves) lies in the presence or absence of a variable speed.

  • The conventional electric winches: no variable speed -> curves.

  The performances of conventional electric winches (operating at 12V DC and lacking variable speed) are represented by a single curve (in the case where only one of the two speeds of the winch is motorized) or possibly by two curves (in the case of winches with the two motorized speeds). Being devoid of variable speed, these winches offer a single furling speed for a given tension, without the possibility of adjustment.

  • SailForce: variable speeds -> a surface.

  The SailForce electric winch has two variable speeds. This means that at a given voltage it offers a speed range from its minimum speed to its maximum speed. Thus, its performance is represented as a surface, encompassing its speed range from minimum speed to maximum speed.

  Adjusting your sails: the importance of minimum speed.

  For fine and precise adjustments, the important thing is to be able to use the electric winch as slowly as possible, regardless of the tension on the rope.

  SailForce, with its two variable speeds , not only offers a lower minimum speed than all conventional solutions (less than 1.7 cm/second), but above all it is possible to have this minimum speed whatever the tension on the rope, therefore whatever the maneuver, and both at the beginning and at the end of the maneuver.

  None of the conventional electric winches (12V DC without variable speed) allows a sufficiently low speed to be able to make precise adjustments regardless of the tension on the rope. They do not have variable speed, so their speed depends entirely on the tension on the string. And if this speed can possibly be adapted for one maneuver, it will most certainly not be adapted for another maneuver, each maneuver requiring very different tensions on the ropes.

  SailForce is at least 25% faster at high winch speed.

  At the start of a maneuver (raising the mainsail, tacking, etc.), speed is the best ally. At this time, the tension on the rope is relatively low, we use the high speed of the winch to go as quickly as possible before switching to the low speed of the winch when the tension increases and/or when we want to perform precise adjustment.

  Conventional electric winches (12V DC without variable speed) offer more or less satisfactory speed when the tension is low on the ropes (left part of the graph), as you can see there are very big differences in performance;

  During testing of our new SailForce electric winch, we had the very pleasant surprise of discovering that its performance in terms of high winch speed exceeded our expectations. Expectations:

  For all winch sizes, SailForce high speed is at least 25% faster than all conventional electric winches.

• Safety: Tension limiter

  See prices Electric winch prices Conversion kit prices

  Super-sensitive tension limiter

  Deck equipment protection

  The tension limiter of SailForce™ is designed to detect scenarios such as a stuck reefing line or even a knot caught in a clutch.

  

  Simply select a tension limit between 10 kg and the maximum line load of your winch (from 850 kg for a size 40 winch to 1550 kg for a size 70 winch). The motor stops instantly when the limit is reached.

  

  Fully configurable tension limits

  

  Tensions on the lines vary considerably from one maneuver to another. Therefore, it is essential to be able to configure tension limits specific to each maneuver. That's why we have created Maneuver Programs.

  Each Maneuver Program stores its own tension limits and offers two independent tension limits, one for the fast speed and another one for the slow speed.

  Example : hoisting the main sail with the tension limiter

  

  Step 1 : Hoisting the main sail with the fast speed

  Hoisting the mainsail requires a tension of 100 to 200 kg on the halyard. If a reef is stuck, or if a slider gets jammed, the tension on the halyard will suddenly increase.

  Simply adjust the tension limit of the winch's fast speed (speed 1) between 100 and 200 kg, depending on the boat (size and configuration). The motor will immediately stop, thus avoiding the risk of breakage in case of an anomaly.

  The motor will immediately stop, thus avoiding the risk of breakage in case of an anomaly.

  Step 2 : Tightening the mainsail with the slow speed

  Depending on the sailboat, the required tension varies between 450 and 800 kg (this tension may be higher for larger boats).

  Therefore, you simply need to set the tension limit of the winch's slow speed to an adequate level to ensure the completion of the maneuver.

  It fully controls the Brushless motor, regulating the current to the motor based on the required torque and ensuring current commutation inside the motor to control its speed. It also stops the motor when the tension limit is reached.

  

  1250W Brushless Outrunner Motor

  The efficiency of Brushless motors is significantly higher than that of 12V brushed motors traditionally used in electric winches. Furthermore, the absence of brushes minimizes mechanical wear, significantly extending the motor's lifespan.

  

  Gearbox and angular reducer

  The combination of a gearbox and an angular reducer exceeds in efficiency conventional worm gear systems.

  Resulting energy efficiency : 65%

  This represents an energy efficiency twice as high as that of traditional 12V motors, which have an efficiency of only 35%. Consequently, it is 50% of energy saved and available for other uses onboard.

  Data collected from public technical documentation SailForce™ data obtained from Ewincher tests

  Motor powered by a 30V DC lithium battery

  For optimal performance, the 12V DC supplied by the service batteries is not sufficient. That's why the SailForce™ electric winch is powered by its own 30V DC lithium battery that charges on the 12 or 24V DC, with a capacity of 144Wh, which is more than enough to power one or two electric winches.

  

  The SailForce™ battery is included with the motor. It serves as a buffer battery, acting as an energy reservoir. When the electric winch is in use, it provides the winch with a powerful 30V current, with an intensity of up to 45A. When the winch is not in use, the lithium battery gradually recharges from the service batteries until it reaches its full charge, after which it no longer consumes energy from the service batteries.

  It can be installed wherever you like in the cabin, up to a distance of 8 meters from the electric winch. All necessary cables are provided.

  Preserves the service battery

  

  The service batteries are typically designed for onboard equipment such as lighting or refrigeration, which rarely consume more than 6 amps. Therefore, these batteries are not suitable for the significant discharges required by an electric winch. The SailForce battery never consumes more than 6 amps, a consumption rate that may be comparable to that of the onboard refrigerator for a few minutes

  

  No need for additional service battery

  Wear on the service batteries caused by traditional 12V electric winches with brushed motors.

  These motors are directly connected to the boat's service batteries, without an intermediate buffer battery.

  

  They draw very high-intensity currents, reaching up to 200 or even 300 amps in some cases. In addition to wasting energy onboard, these high currents have a significant impact on the longevity of the service batteries.

  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.
