original Track. See the
Dodge and Jog Lever Turns sections for more information.
You can limit the maximum amount of rudder travel in NAV mode by turning on the Auto/Nav
rudder limits. Turning them on, and adjusting them to suit, is done in the Power Steer menu.
The SP38 has an automatic Off-Course Alarm that will be activated should the vessel fall off
the commanded course in NAV mode, by more than 20°. There is a 32 second delay on this
alarm.
