Have an Alan Pape 43'
cutter that I drive with a tiller pilot connected to an
Aries. Also have a 33' Ted Brewer
cutter that has a aux
rudder vane with a trip tab. That has a little stub to accept a tiller which could be used. Force seems to be pretty moderate.
I gotta believe it is doable if you can
work out the linkage and support for the tiller pilot.
I have had some bad luck with
RayMarine tiller pilots, but perhaps it was just bad luck.
