My AT34 has Vessel View by SmartCraft and has a rudder position indicator..... which I find useless because of its location on the display. I added a Garmin rudder position indicator at near eye level. At the same level, I have a Garmin depth sounder indicator attached to a glue, to the inside of the hull, depth sounder.
To me, these two indicators plus a magnetic compass and current paper charts can get you home or to your destination, if necessary.
Did Noah have a get home-engine?
