Turn rate limit
This limits your boat’s rate of turn under SPX-5 Wheel system control.
Off course angle
This screen determines the angle used by the OFF COURSE alarm (see your
Operating Guide). The OFF COURSE alarm operates if the pilot strays off course by
more than the specified angle for more than 20 seconds.
AutoTack
The AutoTack angle is the angle through which the boat will turn when you select an
automatic tack
See
User calibration, page 50.

RESPONSE
Range = 1 to 9
Level 1 to 3 minimizes the amount of pilot activity. This conserves
power, but may compromise short-term course-keeping accuracy
Level 4 to 6 should give good course keeping with crisp, well con-
trolled turns under normal operating conditions
Level 7 to 9 gives the tightest course keeping and greatest rudder
activity (and power consumption). This can lead to a rough passage
in open waters as the SPX-5 Wheel system may ‘fight’ the sea.
