Hi Jeff,
As it is difficult to understand and to be understood when we do not speak the same language
Yes, I use the rudder, but on my joystick, in twisting the handle to the right or the left, to steer my aircraft on the ground (or on the water for amphibious and floats) or the boats on the water.
What I do not have, is a rudder with pedals.
Yesterday, when I tested the Sirocco with your files, I could not steer the boat with the rudder of my joystick, it ignored my actions and continued straight.
By cons, in serving me the handle of the joystick, in swinging to the right or the left, the boat goes at right or left.
What I would like, is that the boat turns right and left by using the twist of the handle (rudder mode), as for the aircraft on the ground, and not in swinging the handle to the right or the left as for aircraft in flight
I have not yet tested the autopilot ; for now, I just tried to steer the boat manually.
For the rest, I will try to better understand and continue testing, thank you
