[TG] [TG11] Linear Drive "Fluttering" when turning to Port

[Tom - Raymarine - Moderator]

Hello Bob,

The rudder bar on the display is designed to show a specific (numerical) rudder angle, e.g. 25 degrees port, rather than scaling to your boat's range. The software of the display sets the upper limit for displayed rudder angle in the bar at 30 degrees either side, which covers the majority of boats. If your boat has more than 30 degrees of movement either side then that simply can't be displayed by the pilot controller.

The pilot has a software setting, Rudder Limits, which controls the maximum range of motion that it will try to drive to when Auto/Track/Vane/Power-Steer modes. This defaults to 30 degrees but should be calibrated at installation to match your boat, and should be set - as it sounds like yours is - to a few degrees narrower/before the physical end-stops. This is to prevent the pilot driving up against the physical end-stops and stalling and perhaps damaging stuff. I mention this just for completeness.

I'm glad to hear the new rudder reference has solved the problem.

Regards,
Tom
