[C320-list] Autopilot

[Adam Weiner]

Up to recently it was a very large military port with the Hunter's Point
Naval Shipyard, the Alameda Naval Air Station, Mare Island and I believe
that Port Chicago is still being used.  The one closest to me that
causes me the biggest issue is Hunter's Pt. which was last used for
testing propulsion systems for nuclear warheads.  They had a crane that
could lift basically anything smaller than a battleship.

All were heavily used even after Vietnam, and a number of liberty ships
were built in the causeway that is now the channel for my marina.
Hunter's Point was used extremely heavily in both World Wars and even
after Vietnam.  Apparently a whole lot of metal went into the Bay.

There are also large cables in the Bay and the charts list "degaussing
stations" for these which apparently relate to trying to demagnetize
ships vis a vis land minds in WWII.

And the last war in San Francisco Bay was when?

Before my autopilot gave up the ghost I had terrific problems with the
unit in SF Bay were it would just take off at random in weird
directions.  Went on a several day ocean trip and low and behold, no
problems.  I asked around and found out that were it was going crazy was
places in the Bay know for a lot of metal on the bottom (left over from
wars, dredging, etc.)  This could very well be an issue for you.

 I've followed the list for the past 2-3 years re. ST-4000 settings.
I've 
tried everything offered, but my unit just will not keep a course
withing 
+/- %deg.  Often, the "Wind Mode" works better than compass mode.  The
problem seems to be worse in light air and small seas.

My flux-gate compass is mounted in the aft cabin on the bulkhead behind
the 
galley.  This seems too close to the engine for my taste, and I'll move
it 
to a lower centerline location one of these days.  I'm hoping the damn
thing 
will just fail completely so I can justify buying a new unit with a
rudder 
pos. transducer.
