Whether you cruise coastal waters or embark on blue‑water passages, a reliable Raymarine autopilot can transform your time at the helm. By automatically keeping your vessel on course—even in challenging conditions—Raymarine’s Evolution™ series lets you conserve energy, improve navigation accuracy, and enjoy hands‑free convenience.
1. Why Choose a Raymarine Autopilot?
- Advanced Evolution™ AI: Adaptive steering algorithms learn your boat’s handling characteristics for pinpoint accuracy.
- Robust Sensor Suite: The EV‑1 sensor core fuses 9‑axis motion data to maintain heading in rough seas.
- Seamless Integration: Raymarine autopilots connect effortlessly to Axiom® chartplotters and NMEA2000 networks.
- Energy Efficiency: Intelligent drive control minimizes power draw, ideal for sailboats on long passages.
2. Key Components of a Raymarine Autopilot System
A complete Raymarine autopilot typically includes:
- EV‑1 Sensor Core: Detects pitch, roll, yaw, and heading changes.
- ACU (Actuator Control Unit): Powers and commands the drive unit.
- Drive Unit: Hydraulic, mechanical, or tiller—selected to match your vessel’s steering type and displacement.
- Control Head: p70s or p70Rs for sail and power; provides intuitive push‑button or rotary control.
3. Selecting the Right Drive Unit
Choosing the correct drive is crucial for performance and longevity. Match your boat’s displacement (fully loaded) to Raymarine’s drive‑size recommendations. For example:
- Type 1 Hydraulic: Up to 22,000 lb (10,000 kg)
- Type 2 Linear Mechanical: 22,000 – 33,000 lb (10,000 – 15,000 kg)
- Type 1 Rotary: Suits cable or chain steering on lighter vessels
4. Installation Tips
Proper installation ensures your Raymarine autopilot performs flawlessly:
- Mount the EV‑1 sensor on the vessel’s centerline, away from magnetic interference.
- Use high‑quality marine cabling and waterproof connectors.
- Calibrate the compass and perform the “Dockside Wizard” before sea trials.
- Secure the drive unit on a solid structure to prevent flexing under load.
5. Calibration & Sea Trials
After installation:
- Run the Dockside Wizard to set rudder limits and drive type.
- Conduct a slow‑speed circle to auto‑calibrate heading and deviation.
- Fine‑tune response levels (1–9) to balance course‑keeping and power consumption.
6. Maintenance Best Practices
Routine checks keep your Raymarine autopilot shipshape:
- Inspect hydraulic fluid levels (for hydraulic drives) each season.
- Grease mechanical or linear drive fittings annually.
- Update Raymarine software via Axiom or a laptop to access new features.
- Check cable glands and seals for moisture intrusion after heavy weather.
7. Troubleshooting Common Issues
| Symptom | Possible Cause | Solution |
|---|---|---|
| Course wander | High response setting | Reduce response level |
| Drive stalls | Low battery voltage | Check charging system |
| No rudder feedback | Faulty rudder reference | Inspect/replace sensor |
8. Final Thoughts
A dependable Raymarine autopilot reduces fatigue, boosts safety, and frees you to trim sails or simply savor the voyage. By selecting the right components, following best‑practice installation, and maintaining your system, you’ll enjoy precise, hands‑off steering for years to come.
