6 Adjusting Autopilot Settings
Type 150G/400G autopilot systems
Type 150G/400G autopilot systems have 9 possible response levels.
Type 150/400 autopilot systems
Type 150/400 (non-GyroPlus) and Type 100/300 autopilot systems
have 3 possible response levels:
Turn rate limit (trn rtE)
Note: Not available if vessel type = 6 (Sail boat).
This limits your boat’s rate of turn under autopilot control.
Options
1 to 9 • level 1 gives the least pilot activity to conserve power, but
may compromise short-term course-keeping accuracy
• levels 4 to 6 should give good course keeping with crisp,
well controlled turns under normal operating conditions
• level 9 gives the tightest course keeping and greatest
rudder activity, but may lead to a rough passage in open
waters as the autopilot may ‘fight’ the sea
Setting
1
AutoSeastate on (Automatic deadband)
• autopilot to gradually ignores repetitive boat movements
and only react to true variations in course
• provides the best compromise between power
consumption and course keeping accuracy
2
AutoSeastate off (minimum deadband)
• provides tighter course keeping
• increased power consumption and drive unit activity
3
AutoSeastate off + counter rudder yaw damping
• provides tightest possible course keeping by introducing
counter rudder yaw damping
