AutoTrim settings

AutoTrim determines how quickly the autopilot applies ‘standing helm’ to correct for trim changes, caused, for example, by changes in the wind load on the superstructure, or an imbalance of engines. Increasing the AutoTrim level reduces the time the autopilot takes to return to the correct course, but makes the vessel less stable. If the autopilot:

• Gives unstable course keeping and the vessel ‘snakes’ around the desired course, decrease the AutoTrim level.
• Hangs off course for excessive periods of time, increase the AutoTrim level.
