vane and tillerpilot

tom- how do you rig the connection between your tillerpilot and your
tab. i have an ancient tillerpilot 1600 and cannot seem to get it to
steer well. the problem seems to be too slow a response of the boat
to tab input resulting in gross oversteering-hard over to hard over.

John, based on Mike Anderson’s recommendations, we 1) connect the
tiller pilot ram to the trim tab on the apex of the rudder pintels,
i.e. an imaginary line up through the pins, and 2) set the pilot’s
sea state and gain controls to the lowest (or next lowest) setting
since it is only driving a light load on a very short arm. Mike
recommends these settings as a starting point to finetune each
individual boat, but they have worked for us. I have heard from
others that the placement of the attachment pin (#1) is critical, and
misplacement can lead to an accumulating navigation error that the
autopilot’s “brain” can’t correct.

Hope this helps.
