I’m trying to find the magic settings for an ST4000 autopilot on an
F35. I’ve even read the instructions (shows you how desperate I am) and
spun the compass and tried every combination of rudder gain and sea
state settings and the boat still tracks like a drunken sailor. Any
help would be much appreciated. Thanks.

I also just installed that model on my Freedom32 and couldn’t get the settings right either. I contacted Raytheon and they told me what settings to use and now it’s much better-not 100% but remarkably better. I don’t remember the settings they suggested, but email them and they will tell you.

I installed a Raymarine ST400+ on my Hoyt32 around a year ago,
and after a fairly typical adjustment period I’m quite happy with
it’s performance. One thing I found to be surprising was the factory
default setting for rudder response was set to a point where when
the boat came about (on pilot) the turn was so violent that it
threatened to fling you overboard (or so it felt). Once I adjusted
that down to an acceptable level the boat held headings very well.
Another thing to consider is the location of the fluxgate compass.
Some installers are not too careful about locating it higher that it
should be. Naturally the motion of the boat adversly effects the
compass the higher it is. Bottom line, the compass should be located
as close to the roll center of the boat as possible.
This pilot also has the neat capability of receiving NMEA 0183
data from your mast head wind instrument. I hooked mine up and now
have a pretty good “wind vane” steering system, although it does
sometime get confused in light “flukey” conditions.
I’ll be happy to send my settings for my Hoyt32 to anyone who
wants them.

PWM,
I’d appreciate seeing your autopilot settings. We have an ST4000+ on our Mull 28 and imgaine that the settings would be similar. I’ve never delved into the adjustments; one of those thing I’m going to do the start of every season and then never get around to. Our fluxgate is about even with the mast, but somewhat high - at the top of the V-berth hanging locker. Perhaps I should move it down a bit?
Thx,
dge

Thanks for the responses. The fluxgate compass is installed at the base
of the companionway stairs. It looks like a good location, low and
close to the center of the boat. I have the rudder gain set at 2, which
keeps the boat from overshooting when you ask it to tack on autopilot,
but it still swings over with considerable authority. I haven’t tried
the wind vane setting yet. That’s a good suggestion as the boat may
behave very differently. I’ll give it a try the next time I’m out. If
you have your setting I’d be interested in looking them over. Cheers.

After mine was installed and I tried it out, adjusted it, and couldn’t get her from “snaking” all over, I contacted Raymarine and these are the settings they suggested and it’s pretty much on track now:
Cal Lock-OFF-----Rudd gain 2-----Response 2-----Turn Rate 30-----Align Rud 0----- Rud Limit 23-----Off Course 20-----Auto Tack 100%-----Auto Trim 2-----Drive type 2-----Variation 0-----Augoadapt Off-----Lattitude 45-----Rudd Damp 1-----Cruise Sp 6
Hope this help’s

Sward,
If in fact you have your pilot “drive type” feature set at 2, you may want to change it to “1”. The “2” setting is for hydraulic drives, while the “1” setting is for Mechanical drives, which I assume is what you have.
My settings are as follows: Rudder gain=3, Response=1, Turn limit=20deg, Rudder align.=0, Off course alarm=20deg., Auto trim=1, Drive type=1, Lat=33, Rudder dampening=1, Cruise speed=5. I have my auto tack angle set at the default 100deg. I’m thinking of changing it to 105deg to see if it foots off better on the new tack. We’ll see.
Hope this helps anyone who’s interested.

Paul,
I know that should be the appropriate setting, however, Raymarine suggested I use 2 and that has worked. I however, haven’t used the autopilot when sailing-only motoring, so that could be a different story.
