Ah, okay, when I spoke of hydraulic power pack for the AP I meant below deck
hydraulic ram attached between hull
and quadrant with 1/16 to 1/8 hp motor
turning the pump.
Any tiller or wheel
pilot lacks the power and longevity to be helpful in bad conditions. The time it takes the pilot to turn the rudder
from one extreme position to the other is also very important. From memory I say ours takes 6 seconds and I believe the recommended value is 8-10 seconds or so. When this is too slow, the steering
corrections come too late so that it looks like over correcting. In reality the correction was good but it took too long to move the rudder
in position so the steering
is lagging and actually making it worse.
This is only with the waves on the aft quarter.
