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.
