We are expecting high winds on the weekend, so I doubt I'll get the chance before Monday to trial it. I will if I can on the weekend if weather lets me.
I would suggest setting RUDDER on 1,its lowest setting
with YAW setting on about 5
and SEA STATE 1 to start with.

then adjust the YAW setting upwards if it still wanders.
also you want to be doing more than 3 knots.
for slower speeds or greater rudder movement up the RUDDER setting.

SEA STATE,adjust according to Beaufort ie setting (1)=force 0-1 ,setting(2)=force 1-2 and so on

and hope you don't need the highest setting of 10!

Thanks Atoll, I'll try them first.

Sea State setting is only 1 or 2 I think? I'll check that.

I cant remember either! it may be rudder and yaw are on a 1-5 scale,and sea state 1-3,

but recommendation stands ,ie rudder on lowest,yaw midway,and sea state lowest to start with

Re: Raymarine St4000 with Trim Tab Problem

In the ST4000+, the setting is Response (not SeaState). When Response is set to 1, then it's called the AutoSeaState setting.

The Response setting to avoid is Response = 2. That causes the autopilot to try to maintain a tight course, e.g. by trying to correct for each wave.

Ok what else might YAW be called

I have the following in the manual,

Rudder gain - 1 to 9. Defaulted to 5
Response - 1 Seastate on or 2 Seastate off . Default is on
Auto trim - Off, 1-4. Default is 3 - 1 is slow, 4 is rapid
Rudder Daming - 1-9. Default 1
Cruise Speed - 4-60. Default 6

Oh, and I found Rudder Limit (15 to 40) which I need to work out and set to stop it going beyond its ram limits when the trim tab is way over

I took it into Glascow Engineering, so I was expecting quite a hefty price. My usual welder at the slip yard would have charged me at least $100

sorry I was confusing your AP with the later raymarine ST6000 ,yours is the one with the black control head formerly autohelm/raytheon,not the newer raymarine grey

the auto trim I think equates to the YAW setting
Response=Sea state
Rudder gain= Rudder

the only problem with these are that they were designed to use the rudder reference unit for feed back,which I gather you have not fitted,so the the settings are going to be quite critical for its correct operation,as it is not quite as "bright" as the later models.

they recommend doing a 40degree turn to check the rudder gain for over or under steer when setting up,this will be quite critical as well,also the speed setting.

I would suggest some in depth study of the manual to get the settings right

Yes, it's the black, though it's new, it's also obsolete.

Yes, the book recommends 40 degree turn to check the rudder gain. If it's more than five degrees out, then reduce the gain.

Is not the ST6000 older than my ST4000+?

not sure as the st 6000 also came with the black control head but was able to use the upgraded st6001 which is the grey one.
does yours have a type 100 coarse computer?

I have no idea Atoll. Can't identify that in the manual either.

Re: Raymarine St4000 with Trim Tab Problem

Rustic Charm:

Atoll is asking about the control electronics you have for your ST4000+ GP arm.


For example, do you have a stand-alone control head, with an LCD display, buttons, and its own integral course computer, and to which the fluxgate compass and cables to the ST4000 arm connect? If you have a stand-alone control head, it would likely be grey and labelled ST4000 or ST5000. The last stand-alone control head from Raymarine was I think the ST5000+. You should find an image of an ST5000+ at: http://i.ebayimg.com/00/s/MTIwMFgxNj..._id=880000500F


Or do you have a Type 100 or Type 300 course computer that interfaces with a control head labelled ST6000+, ST6001, or ST6002? Some of the ST600x control heads look similar to the ST5000. Others are black, not grey, and only have a single line LCD display.

I have the ST4000+ which looks like the picture you put up. Separate fluxgate compass on the mast. It's grey in colour. I thought this was clear from the photo's

thanks for the clarification
my concern was that I was giving him advice on how to program the newer unit with the easier and more user friendly softwareas you found in the st6000+ onwards series,a vast improvement with predictive software,so the AP "learned"to anticipate minute coarse changes.

the older units such as RC has were some of the first digital units Autohelm produced after their very successful series of analog auto pilots.

so instead of having buttons to push and knobs to turn for fine tuning you were faced with a very clunky series of menu commands for control and no predictive programming,relying on brute force,and action/reaction feedback from the heading unit and rudder reference unit for its micro processor!

a bit like modern cars ,as opposed to the older ones where you could still lift the bonnet to see what the problem was
