Actuators: the muscle of your autopilot

The actuator is the heart of the autopilot, translating electronic commands into physical movement at the helm. At Skysat, drawing on our experience in offshore racing, we know that a reliable and precise actuator is crucial for maintaining course and optimizing your sailboat's performance. Here you'll find a carefully curated selection of actuators, from linear models to rotary cylinders, suited to different types of boats and requirements.

types of actuators

The choice of actuator depends on the size of your boat, its steering system type, and your specific needs. Understanding the different types available is essential for successful system integration.

• Linear actuators: Ideal for tiller steering or hydraulic steering systems, they offer direct and precise thrust. Leading brands: Raymarine, B&G.
• Rotary actuators: Designed for wheel bars, they transmit movement via a gear system. They offer high robustness and simplified installation. Leading brands: Lecomble & Schmitt, Octopus.
• Hydraulic cylinders: For larger boats, they provide significant power and high reliability. Compatibility with existing hydraulic steering systems should be verified. Leading brands: Lewmar, Hypro.

selection criteria

Several factors must be considered when choosing your actuator. Power, compatibility with your autopilot, and ease of installation are essential elements.

• Output torque: Determined based on the size and displacement of your boat. Insufficient torque can lead to loss of control in challenging conditions.
• Power consumption: An energy-efficient actuator is essential, especially during long voyages. Check the power supply voltage (12V or 24V).
• Compatibility: Ensure compatibility with your navigation system and autopilot (SeaTalk NG, NMEA 2000).
• Stroke: The actuator stroke must be adapted to the maximum rudder angle of your boat.

installation and maintenance

Proper installation is crucial to ensuring the performance and reliability of your actuator. Regular maintenance will extend its lifespan.

• Professional installation: Recommended for complex systems, especially hydraulic cylinders.
• Calibration: Essential for optimal autopilot operation. Follow the manufacturer's instructions carefully.
• Regular maintenance: Checking oil levels (for hydraulic cylinders), greasing joints.
• Corrosion protection: Regular cleaning and application of anti-corrosion products.

💡 Skysat's advice

Before choosing your actuator, check your boat's power supply voltage and its compatibility with your autopilot. An incorrect match can lead to malfunctions and compromise your navigational safety.
