50 SmartPilot X-5 Wheel Installation & Setup Guide
AutoTack
Use this screen to select how the vessel performs when using AutoTack. You can
either:
• Set a default AutoTack angle. This is the angle through which the boat will turn
when an AutoTack is performed.
or
• Select Relative Tack operation. With Relative Tack selected, the apparent wind
angle when AutoTack is initiated, is mirrored the other side of the wind, on the
opposite tack.
Setting default AutoTack angle
To set the required AutoTack angle:
• If the SPX-5 Wheel system is receiving wind information, set the AutoTack angle
to the required change of heading.
• If the SPX-5 Wheel system is not receiving wind information, set the AutoTack
angle to 20° greater than the actual required change of heading.
For example, to tack through 80° (i.e when sailing at 40° to the wind), set the
AutoTack angle to 100°.
Selecting Relative Tack
To select Relative Tack, use
-1
and
-10
, to reduce the tack angle value to 30°. This
action selects Relative Tack and the screen displays
rEL
, to indicate this.
Gybe inhibit
With gybe inhibit on:
• You will be able to perform an AutoTack into the wind
• The SPX-5 Wheel system will prevent the boat from performing an AutoTack
away from the wind, to prevent accidental gybes,
With gybe inhibit off, you can perform an AutoTack into or away from the wind.
Wind selection
This screen determines whether the boat steers to apparent or true wind in Wind Vane
mode.
