through water. If none of these are available, the AWF will use a
boat speed that is 1.5 times the Transition Speed set in the
Installation/Seatrial menu. Turn the course knob to adjust the
wind damping.
Range: 1 – 100 seconds
Default: 15 seconds
Depth Offset
Note ! This adjustment only applies to “smart” depth transducers that
outputs depth on NMEA2000 format. NMEA0183 sentence
‘DPT’ contains offset and the depth reading is from the surface.
NMEA0183 sentence ‘DBT’ contains no depth offset and the
reading will be from the position of the transducer.
When the depth offset is set to
zero, the indicated depth is
from the transducer to the
bottom. To read the depth from
the water surface to the bottom
you have to set the depth offset
according to the vertical
distance between the surface
and the transducer, i.e. positive
(+) value
To read the depth from the keel to the bottom you have to set the
depth offset according to the vertical distance between the
transducer and the keel, i.e. negative (–) value.
Automatic tuning
Automatic tuning is a feature that automatically sets the two
main steering parameters (Rudder and Counter Rudder) by
taking the boat through a number of S-turns. The scaling factors
of the parameters are also set automatically as a function of the
boat type selection performed in the Dockside menu.
Automatic tuning is an optional procedure that is not required for
the AP25 to function. The AP25 is preset with steering
parameters that should steer most boats in the 30 - 80 foot range.
It is, however, recommended to perform an automatic turning as
part of the sea trial.
