Before you start
Gather the appropriate supplies and review the specific equipment manual.
- Autopilot manual
- Compass or heading data
- Steering inspection notes
Step-by-step instructions
Check manual steering first
Confirm the wheel or tiller moves normally and the boat is not experiencing uncontrolled weather helm.
Observe the pattern
Record whether hunting occurs only under sail, under power, or at certain speeds and sea states.
Check instruments and power
Look for low voltage, unreliable heading, rudder-reference faults and connection alerts.
Compare calibration settings with the manual
Follow the model-specific dockside and sea-trial procedures only in safe open water.
Test one adjustment at a time
Document response and return to safe manual steering immediately if performance worsens.
Safety note
Autopilot is not a lookout. Keep a responsible watch and be ready to take immediate manual control.
Key takeaway
Steering friction and poorly balanced sails can mimic an autopilot-tuning problem.
