Safety: Tension limiter
Safety: Tension Limiter.
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.
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.
Adjust the tension limits.

Through the SailForce electric winch smartphone application, available for iOS and Android.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 sailboatOnly 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.

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.

Motor - dimensions & installation
SailForce is the most compact underdeck engine on the market today.
Our motor is so powerful that we use the same one for size 40 to 70 winches. The space saving in the cabin compared to conventional motors (12 or 24V DC brushed motors) is considerable for size 50 winches and more.
The motor can be installed at 30 degree intervals around the winch axis.
Cables - compact and flexible
All the cables necessary for the installation of our electric winch are provided:
Lithium Battery / Motor Cables:
Our cables are significantly thinner than those of conventional motors, thanks to our technology (brushless motor powered by a 30V Lithium battery). We opted for H07VK flexible multi-strand cables, known for their great flexibility, which considerably simplifies installation. We offer three options:
- 2x2.5 meters, section of 6 mm², ext. Ø. 5 mm
- 2x5 meters, section of 10 mm², ext. Ø. 6 mm
- 2x10 meters, section of 16 mm²
For comparison, conventional motors for a size 40 winch require cables with a section ranging from 30 to 50 mm², with an external diameter of 12 to 14 mm.
Lithium Battery power cable: length 2 meters, Ø 6 mm
Motor Cable(s) / Control Instrument(s):
Depending on the type of order chosen:
- Essential Command: 2 meters, Ø 5 mm
