I'm having a hard time getting my
rudder amidships in tight quarters (I have
hydraulic steering so it's a bit vague) and the auto pilot display in the pilot house is hard to read from the
cockpit. I've been wondering about the best way to add a
rudder angle indicator in the
cockpit and I'm hoping for some
advice on how to do it efficiently.
The auto pilot is an old Robertson/
simrad AP20 which uses an RF300
sensor at the rudder post via a linkage. It looks like there were Robertson branded indicators that can be connected to that system but it's unclear which one fits what and they're all used and very expensive items.
I'm not sure if the AP20 actually provides rudder angle as
nmea and if so where but maybe there's some kind of generic display that I could interface with that?
As an alternative I was thinking of
purchasing a completely redundant system such as the
Raritan rudder master. This would be a second angle
sensor and an indicator with a junction box, I could add a second linkage or maybe they can "share" the linkage.
