[C320-list] Autopilot install

[Scott Westwood]

2 cents,
When I looked at linear vs/ wheel I found this (Others, I'm sure, have other findings):
Like most things it depends on how you use your boat.
1. Linear was more robust directly connected to tiller. (We put a small bungee on the engaging lever to keep ours engaged.  It does pop off if you don't.)2. Linear is more costly overall including to install.
>From what I read a tiller sensor helps eliminate fishtailing.
We went with the wheel because:
1. We don't use it often.  If I'm in rough seas my hands are on the wheel always.   The wheel should handle things long enough to address most things (we do).  If rough seas we would/should be secured.  There are always unexpected though....We also don't plan to do much long distance overnight type of trips.2. Nobody ever answered the question: "How easy is it to dis-engage if it fails?"  What if the helm is hard right and it locks up or the control unit fails?  How easy/hard is it to dis-engage in an emergency?  It may be simple/quick but I never got a clear answer and that concerned me (at the time).3. Price and ease of installation.  Sounded like linear would be custom work by a boat yard and/or custom hardware.
Whatever works for you.  These could have changed but Wheel was good enough for us.

Angus,

I also installed the linear drive on Odyssey #688.  There is no comparison between the two drives.  I single hand all of the time and can point the boat on any course, push the button on the autopilot and it will hold the course in a straight line. The linear autopilot was designed for boats up to 24,000 lbs so it doesn't have any problems with the C320.  It is especially useful when dropping the sails with the Dutchman system. On my boat the sails drop nicely except for the portion at the rear which tend to fall off the boom. I can put the sail cover on without any worry.

Graeme.  I was interested that you had decided on the linear drive which is below deck I believe.  I was wondering whether you had chosen the linear model to make it easier to remove the wheel while at anchor or for better control of the boat.  In the later respect I find that the 4000+ does not control the boat very well especially in 10kts or more.  The boat actually goes upwind .when close hauled without the AH.  Of course this needs trimming the sails just right.  I would appreciate your comments.

Would love to hear where others have mounted the sensor, ACU and control unit. I’ve read that the sensor should be centerline and as low to the waterline as possible without magnetic interference. Also, I have space on my helmstation for the control unit between the knot meter and wind gauge. Would that be a suitable place? Thanks!
