2Autopilot makes too frequent course corrections:

3When sailing a straight course, the boat drifts from side to side of the course:

aThe boat should drift from side to side of the course when the autopilot steering is optimized.

bChange to a profile suitable for boat speed and sea conditions (see section 8-2).

cIf the boat drifts too far from the course, adjust response, ratio, counter rudder gain, GPS gain (if autopilot is in GPS mode) or wind gain (if autopilot is in wind mode) (see section 8-1).

4When sailing a straight course, the boat drifts off course:

aChange to a profile suitable for boat speed and sea conditions (see section 8-2).

bAdjust response, ratio, counter rudder gain, GPS gain (if autopilot is in GPS mode) or wind gain (if autopilot is in wind mode) (see section 8-1).

5When making a large course change, boat does not follow the expected course:

aChange to a profile suitable for boat speed and sea conditions (see section 8-2).

bCheck turn rate is not too low (see section 6-3).

cAdjust counter rudder gain (see section 8-1).

6Boat turns too sharply: Reduce turn rate (see section 6-3).
