We own hull #72, and the boat originally came with only the rotary drive above the galley, and one autopilot. I have since installed a complete 2nd autopilot, and have made an adaptor plate for the quadrant which will allow me to install a linear drive on the quadrant. As it is now, I have to do some minor re-wiring to switch from autopilot A to B. I really don't have a clue how to wire the autopilots or 2 drive units to switch back and forth easily.
When you have the time would you mind providing me some more details of how you wired Harmonie to easily switch between drive units and autopilots? Any help you can provide is greatly appreciated. I plan on starting the installation of the linear drive while in St Martin in March, and will try out the system as we work our way to Panama for our canal transit in 2018.
