ComNav 1101 Autopilot
Tide, Wind and Current
If your boat encounters a tide, crosswind or current, the boat will be
pushed away from the desired heading repeatedly, each time in the
same direction. After the Autopilot has made several corrections, the
Processor will simply maintain the rudder a few degrees to port or
starboard of the center position to counter the effect of wind, tide or
current. This feature, known as trim, will keep your vessel pointed
in the right direction.
