Re: Stus-List Autopilot steering

[Chuck S via CnC-List]

Hi David, 
Not sure we answered this fully: 

Under sail, weather helm produces some need to hold the wheel so the rudder is 
4 to 7 degrees off center. 

Under power, propwash creates a turning force that requires the wheel be turned 
slightly so the rudder is several degrees off center to correct course. Higher 
revs mean more propwash, more force to counter. I reiterate my belief based on 
using a meter, that I think the autohelm motor does not pull power unless the 
motor is driving. When things are balanced, she is at rest, drawing zero amps, 
and should never be warm to touch. 

Lastly, I suspect you may be experiencing voltage drop at the motor?

I was on a long cruise last weekend and we ended up motoring for many hours. 
installed a new Raymarine EV1/ST4000+ wheel pilot last winter and this was the 
first extended use. I found that it was frequently cutting out while motoring 
(not sailing). The unit would simply freeze up and stop steering while the boat 
drifted slowly off course. No error on the P70 controller screen until I got an 
off course warning. I also noticed the wheel pilot getting warm/hot when this 
was happening which may be why it cut out. 
I also notice that while motoring, there is significant pull on the wheel that 
has to be fought to keep the boat going straight. Is that normal? I am guessing 
that the wheel pilot is overheating due to the power needed to continuously 
fight that pull? Thanks- Dave

"heating the universe".  :)  Perhaps, but the ever increasing removal of
energy from the planet's atmosphere by wind power will lower its
temperature.  The corresponding decrease in the earth's enthalpy will
result in a new ice age.  The Mississippi River will freeze over all the
way down to Natchez and the Saints will win another Superbowl!

minor correction:  The autohelm motor will use power to keep a steady pressure

  The autohelm motor should adjust the helm to steer
 that course and idle off, so no power being consumed until
 the course changes.

Re: Stus-List Autopilot steering

[Chuck S via CnC-List]

David, 
The shaft of the 34/36 is on centerline. 
Propwash causes the problem you are experiencing. This is normal. BTW, propwash 
is caused by the shaft's downward angle. Saildrives and horizontal shafts have 
zero propwash. On our boat, the pull is half a spoke at full speed, but it 
doesn't take much effort to hold that. Two fingers at most. The autohelm motor 
should adjust the helm to steer that course and idle off, so no power being 
consumed until the course changes. 

I just installed a Raymarine EV-100 and found several differences from the 
ST4000. It's all in the instructions. Check your wire size to be sure you 
haven't used too small a wire that could cause voltage drop. The round trip 
distance between your power source and the device determine voltage drop. My 
power run from the breaker to my ACU is 20 feet. That's a forty foot circuit. 
The fuse in the ACU is 10amps. I ran 12 gauge wire, but some tables indicate 8 
gauge so I may be undersized? The book calls for an 8 gauge ground drain if the 
nearest ground point is more than 3 feet. i plan to test my system this way and 
if I see problems upgrade wire sizes.

Hi Bill- I am not sure about the offset. I did not realize that it was a 
possibility. I will have to check this winter when on the hard. I have a vague 
recollection of it not being straight relative to the axis of the boat and that 
might be why. If so, I guess that would explain the pull. Dave

Re: Stus-List Autopilot steering

[Chuck S via CnC-List]

Hi Dwight, 

I had a different experience. I mounted my St4000 plus Mk II in 2003 out of the 
box and never adjusted anything, no rudder sensor. It worked fine for 12 years, 
many times it steered over 12 hours when motoring on cruises. Following seas 
under full sail presented a challenge, but we learned to hand steer or adjust 
sailplan down to genoa only. 

It recently lost the output signal for port turn. Nobody around here would look 
at fixing it so I bought a new Raymarine EV-100 system and installed that. It 
included a control unit that has sensors for roll, pitch, and yaw similar to 
airplane systems, so I'm looking for improved performance. Haven't had a chance 
to test it thoroughly. Too many family obligations. Maybe this weekend I'll get 
a chance?

David, I can tell you that my Raymarine ST 4000 plus MKII wheel pilot was 
useless until I installed the rudder angle sensor that was supplied with it but 
I am not sure if your new wheel pilot was supplied with a rudder angle sensor.. 
I delayed installing that rudder angle sensor for 2 years because of the the 
difficulty in working below deck on the quadrant of my boat and during that 
time I moved the fluxgate compass forward to a locker below the port settee 
adjacent to the base of the mast and far away from anything magnetic but it 
still wouldn't hold a course. Finally I bit the bullet and wiggled myself and 
the necessary tools back into that cramped dark space to where I could do the 
rudder sensor installation on the quadrant. Once the control head had the 
signal from the rudder sensor the unit worked very well and now aside from it 
working well I also like the readout on the display that tells me my rudder 
angle. I don't quite understand why my wheel pilot required the signal from a 
rudder angle sensor because I thought the unit should be capable of steering a 
course based on compass input alone. This may not apply to you new wheel pilot 
but it does illustrate that everything has to be installed as described to get 
good performance from your wheel pilot so pay attention to where your compass 
is located and make sure all connections are good...you may also have gain and 
response controls on your wheel pilot so also experiment with the settings on 
those for your boat. The little motor that drives the wheel should not feel 
overly warm to touch even after many hours of steering. I am finally very 
pleased with my old Raymarine wheel pilot and very pleased with the repair (one 
blown resistor replaced in the circuit board) that was done by the Raymarine 
service center here in Dartmouth, NS about a month ago.

Pull to port under power is normal given fin keel (reduced lateral stability
from a full keel), prop offset to port and clockwise prop spin.  Not a big
issue.  I just steer accordingly or set the wheel brake with a bit of
tension and the wheel a few degrees to starboard

Stus-List Autopilot steering

[Tom Buscaglia via CnC-List]

David

Alera does the same thing.  As I understand it, the pull to port is a result of 
the prop clockwise spin.  The wheel is about 7 degrees or so off center under 
power.  But my Raymarine X5 wheel pilot has no problem with it, except in heavy 
seas.  But that is expected at Alera is at the top of the capacity for a wheel 
pilot.  You may want to wreck the tension on the belt.

Re: Stus-List Autopilot steering

[Eric Baumes via CnC-List]

The 34/36 has a centerline shaft. I have no significant pull under power
and have a 3-blade Max-Prop.

I have had the 3-blade, and 2 2-blades (long story) and never had
significant pull when cruising. Steering under sail or power should involve
little more than 2 fingers on the wheel making adjustments.

I have an recent Raymarine AP and it does not struggle I have used it for
up to 5 hours motoring ad 3 sailing.

You should be able to check it just by looking at how the shaft exits behind
the engine -

Hi Bill- I am not sure about the offset.  I did not realize that it was a
possibility.  I will have to check this winter when on the hard.  I have a
vague recollection of it not being straight relative to the axis of the boat
and that might be why.  If so, I guess that would explain the pull.  Dave

I was on a long cruise last weekend and we ended up motoring for many hours.
installed a new Raymarine EV1/ST4000+ wheel pilot last winter and this was
the first extended use.  I found that it was frequently cutting out while
motoring (not sailing).  The unit would simply freeze up and stop steering
while the boat drifted slowly off course.  No error on the P70 controller
screen until I got an off course warning.  I also noticed the wheel pilot
getting warm/hot when this was happening which may be why it cut out.

I also notice that while motoring, there is significant pull on the wheel
that has to be fought to keep the boat going straight.  Is that normal?  I
am guessing that the wheel pilot is overheating due to the power needed to
continuously fight that pull?  Thanks- Dave

Re: Stus-List Autopilot steering

[William Walker via CnC-List]

My CnC 36 has prop shaft offset to port and therefore under power boat will 
steer to port unless rudder counteracts with starboard angle.  When motoring my 
wheel is proabably two inches off dead center to starboard to steer straight 
course. The more rpms = more thrust = more port turn = more counteracting force 
required.   Having said that, no issue with autohelm 4000+ handling this.

Re: Stus-List Autopilot steering

[Josh Muckley via CnC-List]

Pretty sure that the 30, 34, and 37 series boats are all centerline.   Past
discussions indicated that the angle at which the shaft leaves the hull
(angle down) influences the pull.  The swirling column of water.

Re: Stus-List Autopilot steering

[Tim Goodyear via CnC-List]

David,

I have a pull to port under power on my 35-3 (the same with new engine and
newly aligned shaft as before) with no pull under sail / coasting.  The
shaft is on center line as I presume is yours.  I've never had the issues
you've described with my Raymarine wheel pilot SPX-5 under power.

I was on a long cruise last weekend and we ended up motoring for many hours.   
installed a new Raymarine EV1/ST4000+ wheel pilot last winter and this was the 
first extended use.  I found that it was frequently cutting out while motoring 
(not sailing).  The unit would simply freeze up and stop steering while the 
boat drifted slowly off course.  No error on the P70 controller screen until I 
got an off course warning.  I also noticed the wheel pilot getting warm/hot 
when this was happening which may be why it cut out.I also notice that while 
motoring, there is significant pull on the wheel that has to be fought to keep 
the boat going straight.  Is that normal?  I am guessing that the wheel pilot 
is overheating due to the power needed to continuously fight that pull?

Is your prop shaft offset so it can be removed past the rudder?

Calling Raymarine was my first action and I am waiting for a call back.  But
what I really want to know from the group is whether the relatively strong
pull to port while motoring is normal or whether neutral helm is normal.

Re: Stus-List Autopilot steering

[Rick Rohwer via CnC-List]

Hi
My 37+ pulls hard to port under full throttle, prop effect I am sure.  I am 
running a 3 blade prop.   You might be able to minimize the effect with a prop 
change.  Good luck.

Re: Stus-List Autopilot steering

[Josh Muckley via CnC-List]

I have the same pull to one side.  I can't remember which side.  This has
resulted in lots of discussion on the list regarding the differences
between prop-wash, prop-walk, and (one other, prop-torque? Torque-steer?)

As long as the helm is balanced during sailing I think you're good.

Stus-List Autopilot steering

[Jean-Francois J Rivard via CnC-List]

Hi David, 

There is some pull when motoring on mine but I wouldn't call it 
significant.. My old autopilot never had issues when motoring, it would 
sometimes run out of juice when sailing in stronger winds..  But being on 
the lake,  I never really motored for more than about 1 hour.  I believe 
Chuck Scheafer has motored  / used the same autopilot pretty extensively 
with no issues that I recall on his 34R. 

I'm told that just like going in reverse, you get some prop walk going 
forward as well.  But that should not be enough to overheat your AP..  I 
forget what kind of prop you are using. Is it known for prop walk?  There 
could possibly be some lube  / binding issues on your steering system, 
perhaps the wheel brake is dragging? Might even be somekind of alignment 
issue on your driveshaft? 

If that was during sailing I would commented about re-checking mast rake 
as it can add significant weather helm in strong winds.. 

I would start by looking at the steering action. 

Chuck, you have any suggestions?

Re: Stus-List Autopilot steering

Does the steering hang up at all when the autopilot is disengaged?

I was on a long cruise last weekend and we ended up motoring for many hours.   
installed a new Raymarine EV1/ST4000+ wheel pilot last winter and this was the 
first extended use.  I found that it was frequently cutting out while motoring 
(not sailing).  The unit would simply freeze up and stop steering while the 
boat drifted slowly off course.  No error on the P70 controller screen until I 
got an off course warning.  I also noticed the wheel pilot getting warm/hot 
when this was happening which may be why it cut out.I also notice that while 
motoring, there is significant pull on the wheel that has to be fought to keep 
the boat going straight.  Is that normal?  I am guessing that the wheel pilot 
is overheating due to the power needed to continuously fight that pull?  
Thanks- Dave

David,

I would talk to Raymarine. Usually, a problem like that could be that the unit 
is not strong enough for the size of the boat, but the ST4000+ should be able 
to drive the 34+, even under power. 

All the best,

Edd
