Init NAV 
Sets a firm or soft approach to the rhumb line when entering the 
NAV mode at the first leg. The approach angle is dependant 
(adaptive) on the distance (XTE) from the rhumb line and the 
boat speed. 
Range:  Soft - Firm 
Default: Firm 
Turn Gain 
Turn gain determines the initial rudder command when turning 
in AUTO and NAV modes. 
Increase this value if the amount of rudder is too small when 
starting a turn. 
Range: 1-320 
Default value is set according to Boat length and Set rate of 
turn
 in the Installation Seatrial Menu. 
W Turn Gain 
W Turn gain determines the initial rudder command when 
turning in WORK modes. 
Increase this value if the amount of rudder is too small when 
starting a turn. 
Range: 1-320 
Default value is set according to Boat length and Set Rate of 
Turn 
in the Installation Seatrial Menu. 
 
Rate Sensitivity 
This parameter determines how sensitive the Rate of turn 
calculation is for changes in the heading signal. The default 
setting will fit most vessels. For vessels that can turn quickly 
and have a stable heading compass (high performance compass), 
the setting should be reduced if the vessel tends to overshoot, 
even with a high setting of counter rudder. For a slowly turning 
vessel with noisy compass and unstable Rate of turn, the value 
could be increased. 
Range:   5 - 25. 
Default:   15.
