[C320-list] Maximum Stop to Stop Wheel Turn Capability

[Bill MacRae]

This is an excellent and timely subject especially for those involved in the rudder sensor project.  Jeff is correct; I was getting dimensions for the brackets and realized that my rudder swings about 180 degrees.  This is probably why the rudder sensor is only good for 120 degrees included.  The swing will have to be reduced or the connecting rod will bend around the rudder post and cause other possible damages. 
 
There are some variables that need to be addressed to ensure that the brackets fit all of the boats.  I will be emailing some pictures and questions to those that have expressed interest in the kits and brackets.  If there is anyone else that hasn’t contacted me who is interested, please write and I will include you in the emails.

On older boats the rudder could swing much more than 60 degrees in either direction. When I installed the sensor on my 1998 I had to add material to the stop because the sensor's swing is physically limited to 60 degrees. Turn it farther than that and parts have to bend or break.> > My guess was that CY changed to a tether to keep the sensor from being damaged. Maybe they did it because the rudder post might be damaged or stall at anything approaching 60 degrees at speed. On my 387 the rudder is limited to much less than 60 degrees and that is very difficult to get used to after owning the 320. Unfortunately, the autohelm drive unit doesn't allow more movement than that. > > There are lots of thing about the 320 that I'm going to miss.
