4. Additional Information for Sailing Vessels
Autotack
The ST7000 has a built in Autotack function which will
turn the vessel through 100 deg. This operates in both
compass and vane modes as follows:-
Vane
Push
+1
and
+10
keys together to
initiate a tack turning to Starboard.
Push
-1
and
-10
keys together to
initiate a tack turning to Port.
Note:
It is important that the rudder angle transducer is accurately aligned
as the Autotack function mirrors standing helm and any offset will change
the initial tack angle.
Wind Trim
Wind Trim allows the autopilot to be supervised by
apparent wind direction. The wind direction is read
either:-
- From the SeaTalk bus (requires Autohelm ST50 wind)
OR
- Directly from a Masthead Transducer (Z080)
OR
- From an NMEA 0183 input on the control unit.
Automatic
Heading
Push both
red
keys
together to
select Wind Trim and maintain the
current apparent wind angle.
Previous Automatic Heading
Push and hold down for 1 second
both
red keys
together to return to
the previous apparent wind angle.
