Speed Response
To make this adjustment you need speed input from either SOG
or Log.
The Speed response adjusts the relationship between speed and
amount of rudder, with lower speed requiring more rudder.
This adjustment should be done at slow speed as follows:
For displacement and planing boats, steer at minimum operating
speed.
If there is a big difference in steering performance for a planing
boat before and after planing, refer to Transition speed on page
83.
For water jet, steer at a speed that begins giving reasonable
response from the main steering.
From the Sea trial menu, select Speed response by rotating the
course knob clockwise. The AP50 will now take control over the
steering of the boat.
If another course is desired (CTS), rotate the course knob until
the desired course is obtained.
Proceed to the Speed response adjust screen by pressing the
(STBD) button. Rotate the course knob to set the Speed
response parameter to the level at which the vessel steers
satisfactorily at slow speed. Change of speed will now
automatically adjust the rudder gain in an adaptive manner
between slow speed and cruising speed.
Range: 0.00 – 2.00
Exit the Seatrial Settings menu by pushing the
button to proceed to the System Data menu, or press the
(STBY) to return to normal AP50 operation.
After having completed all the settings in the Installation Menu,
take the boat out and perform a final sea trial in open waters at a
safe distance from other traffic.
• Steer the boat on all cardinal headings in AUTO mode.
• Start with low and medium speeds to get familiar with the
response from the AP50.
• Try the DODGE, U-turn, and C-turn functions.
