44 ST600R Autopilot Control UnitRudder LimitRudder Limit restricts autopilot rudder movement to just less thanthe steering systems mechanical stops. This avoids putting thesteering system under unnecessary load.The range available is as follows:Range: 15° to 40°Defaults: 30° Displacement, semi-displacement, planing20° SterndriveTurn LimitThis limits the rate of turn of your vessel when under autopilotcontrol. The value must be within the range 5 to 20°. For sailboatapplications it should be set to 20°.Range: 5° to 20° per secondDefault: 20° (Displacement)15° (Semi-displacement)08° (Sterndrive)Cruise SpeedThe Cruise Speed value is used by the autopilot during Track modeoperation, when it calculates compensation for tidal streams andleeway.Set the value to the boat’s normal cruising speed.Alternatively, set Cruise Speed to Auto mode (A) (not available whenusing a Type 100/300 Course Computer) so that Speed Over Ground(SOG) data is used, if available. SOG will normally give better course-keeping than a fixed value. However, using SOG could causeproblems at low boat speeds where the tide exceeds 35% of the boatspeed.Note: If boat speed data is available via SeaTalk or NMEA, the CruiseSpeed setting is ignored and the actual boat speed is used.Range: 4 to 60 knotsDefaults: 6 (Displacement)8 (Semi-displacement)20 (Planing)20 (Sterndrive)
