Yeah, the thing Harry was complaining about on Chuck's Island. The
position
of the knob, when going straight, will vary with the direction of the
wind.
It doesn't mean there's a hydraulic steering problem or anything else,
although I suppose it could.
Um....that's not a "problem" as such - it's entirely normal when
adjusting for windage you will naturally turn into or away from
windage changing the position of the wind.

Remember you have what is essentially a bay boat with no real draft to
keep you from moving when the wind gets up. - in particular if you are
just "cruising" along at a relatively slow speed. *You will have
better control as you speed up.

Eventually, your helm will make a 360 degree turn on you - the
hydraulics aren't pressurized so there will always be some slop in the
system and it will vary with air temp - even your console will have
some effect on the expansion and contraction of the steering control's
hydraulic fluid.

That's one of the little annoyances of light hydraulic steering on
small boats. *In the eight years I've owned the Ranger, my helm has
spun around 360 or eve more than that.

Why did you opt for the knob?
The wind is NOT the issue. Good grief.
The wandering knob syndrome is normal for Seastar hydraulic steering
systems. It's mentioned in the manuals that come with the steering system.
Yesh - and who told you that?

It wasn't the manual.

And I'd love to debate the relative positions of the helm when
steering into or away from wind, but I don't feel like it.

Frankly, I don't know what Harry is talking about. *Every boat I've owned
with hydraulic or cable steering, from the Navigator, the Grand Banks, to
the Scout and Boston Whaler will have different helm positions to compensate
for windage while maintaining a course. * Harry needs to take a ride on a
boat with rudder position indicators, set a course, put the autopilot on and
observe the rudder positions when running with wind on the beam.

Eisboch

We're not talking about the same thing here, I don't believe.

I'm talking about the engine or rudder being entirely amidships, in no
apparent wind or current, and the knob on the wheel being wherever the
hell it feels like being. You and Herring talking about the engine or
rudder being used to maintain a course during the impact of wind,
current or wave action.

Who told me that? A "techie" guy on a real boating discussion board, who
backed up what he said with a quote from the manual.




Your "techie" is full of it.

Hydraulic systems are capable of very fine and repeatable positioning due
to the non-compressibility of the fluid.
They are used often over cable or pneumatic systems when fine positioning
control is required because they overcome the "sticky" nature of
pneumatics and the stretching of cables. In the business I was in we
used air over oil hydraulic systems to precisely move and locate 500 lb
objects to within thousands of an inch.

If the hydraulic steering system has not been purged of all air, or if
there is a leak, I can accept the helm position non-repeatability. But,
if leak-free and purged of all air, it should be perfectly repeatable.

It's the cross wind.

Eisboch

To be sure, if you see Krause's name anywhere in a thread, you will be
seeing a lot of horse **** being thrown around.
Cross wind will cause you to have to adjust helm position to maintain a
straight course but I don't think that is the complaint. the issue is that
when the boat is at rest and the engine is centered, the wheel position has
changed from it's original position.
I just took a peek at the Sea Star Web site. It seems there check valves and
pressure relief valves built into the system. A leak in a check valve or
operation of a pressure relief valve could be the cause of what these guys
are seeing. No? Not to mention seal leakage. I don't think these are
precision devices like the ones Eisboch is used to dealing with. The subject
has been beat to death and if anyone doesn't like the fact that the suicide
knob wont stay at 11 O' Clock, they should contact Teleflex for relief. Or
they could have Eisboch's old company design and build a precision $500,000
helm.

Thank you - these are non-presurrized systems and air leaks happen no
matter what SeaStar says.

The nice thing is that it's easily corrected - add an ounce or two of
fluid and your off and running for another couple of years.

The helm "pump" actually acts more like a worm gear than a pump and
there will be slippage there also over time.

Mine is bled and purged every year and so far, it's been very
reliable.

They are used often over cable or pneumatic systems when fine positioning
control is required because they overcome the "sticky" nature of
pneumatics and the stretching of cables. In the business I was in we
used air over oil hydraulic systems to precisely move and locate 500 lb
objects to within thousands of an inch.

If the hydraulic steering system has not been purged of all air, or if
there is a leak, I can accept the helm position non-repeatability. But,
if leak-free and purged of all air, it should be perfectly repeatable.

It's the cross wind.

To be sure, if you see Krause's name anywhere in a thread, you will be
seeing a lot of horse **** being thrown around.
Cross wind will cause you to have to adjust helm position to maintain a
straight course but I don't think that is the complaint. the issue is that
when the boat is at rest and the engine is centered, the wheel position has
changed from it's original position.
I just took a peek at the Sea Star Web site. It seems there check valves and
pressure relief valves built into the system. A leak in a check valve or
operation of a pressure relief valve could be the cause of what these guys
are seeing. No? Not to mention seal leakage. I don't think these are
precision devices like the ones Eisboch is used to dealing with. The subject
has been beat to death and if anyone doesn't like the fact that the suicide
knob wont stay at 11 O' Clock, they should contact Teleflex for relief. Or
they could have Eisboch's old company design and build a precision $500,000
helm.

Thank you - these are non-presurrized systems and air leaks happen no
matter what SeaStar says.

The nice thing is that it's easily corrected - add an ounce or two of
fluid and your off and running for another couple of years.

The helm "pump" actually acts more like a worm gear than a pump and
there will be slippage there also over time.

Mine is bled and purged every year and so far, it's been very
reliable.

~~ knocks on wood ~~

Forgot to mention that over time, the system loses pressure
internally. For example, if I don't go out for a week, the engine
will gradually tilt port or starboard - the wheel doesn't move when
that happens - it's all internal slip. So if you have the wheel
"centered", when you set up for the next launch, it ain't gonna be
centered - it will be a quarter turn off.

Thus my comment about doing a 360 or more over the years.

You are exactly right - these are not high precision hydraulic systems
- they are strictly low tech hydraulics.

Of course Harry may have some high end Porsche style fancy European
system for his Parker rather than the system us low born boating trash
have to put up with. :)

Boating today...

Who told me that? A "techie" guy on a real boating discussion board, who
backed up what he said with a quote from the manual.




Your "techie" is full of it.

Hydraulic systems are capable of very fine and repeatable positioning due
to the non-compressibility of the fluid.
