[C320-list] Autohelm Crazy Ivan

[Larry Frank]

I had the same thing on WindSwept with the ST 4000.  When I upgraded to the
4000+ model including the new control head and the rudder reference unit the
problem disappeared.

Not only did mine always turn the same way but I too termed the maneuver a
"Crazy Ivan".  This isn't entirely correct though, is it?  Didn't Red
October turn in both directions?

When Otto made the Crazy Ivans on WindSwept he never did detect a trailing
submarine......

To borrow a term from the Hunt for Red October, my Autohelm 4000 auto pilot
will occasionally just make a left turn of about 10 to 20 degrees.  If left
alone it will gradually come back to its course. Any ideas why?
