Rate of Turn

The Rate of Turn sets the turning speed of the vessel used by
the autopilot during large turns.
Range: 5°/minute to 720°/minute.
Default: Dependent on boat length.

W Rate of Turn

Radius
This sets the size of the turning circle for the vessel used by the
autopilot during large turns.
Range: 0.01 to 0.99 nautical mile.

Added stop time
On larger vessels (typically above 300') or quickly turning small
boats, the counter rudder may be insufficient to avoid
overshooting large turns. The Added stop time parameter is
used to stop a turn earlier to avoid overshoot.
