• the pilot will turn onto the new bearing and track towards the next waypoint
Note: Waypoint advance will only operate if your pilot receives valid bearing to waypoint
and waypoint number information.
2.5 Using WindTrim mode
Note: You can only use WindTrim mode if the tiller pilot is connected to a suitable wind
sensor/instrument providing wind direction data.
To use WindTrim mode, the tiller pilot must receive wind information from one of
the following sources:
• SeaTalk wind instrument
• NMEA wind instrument
• Raymarine pushpit wind vane (part number Z159) connected via supplied
SeaTalk interface
In WindTrim mode the tiller pilot maintains a course relative to an apparent wind
angle. The pilot uses WindTrim to eliminate the effects of turbulence and short
term wind variations. This provides smooth precise performance with minimum
power consumption.
WindTrim mode uses the fluxgate compass as the primary heading reference.
When changes in the apparent wind angle occur, the tiller pilot adjusts the locked
compass heading to maintain the original apparent wind angle.
In WindTrim mode, the tiller pilot ignores short-term changes in wind direction,
yet still tracks real wind shifts as subtle as 1°.
Selecting WindTrim mode
From Standby mode or Auto mode, press standby and auto together to select
WindTrim. The tiller pilot will then maintain the current apparent wind angle.
Note: The tiller pilot beeps once every 30 seconds in WindTrim mode.
