I have a catalina 30 from 1990 with an Autohelm 4000 wheel pilot since 1991.The wheel pilot need to be replaced. I have looked to the new Raymarine wheel pilot.When installing this pilot you need also to install a feature connected to your rudder to measure the angle of the rudder. To my opinion there to no space to install this in a Catalina 30. Has somebody face this problem and knows a solution.Thanks in advance.
