I purchased a Raymarine model 100 autopilot. I now need to purchase
the compass and rudder sensor. How do I identify the correct items to
purchase? Are there particular model or part numbers that I should
look for or stay away from?

Doug

Doug,
This is interesting because:
A: I have never heard of an autopilot model 100.
B: All the Raymarine everything a model that start with a letter.
C: The nearest autopilot to 100 is st1000(+) and this is a single unit
tiller pilot and requires only mounting and power.

Next thing to do is read the complete model number a go to
http://www.raymarine.com/raymarine/D...te=1&section=3
and download the manual.
Then, if you still have questions, cone on back here. I here a lot and
will be glad to help if I can.

The models 100 and 300 are the computers that were replaced by the
current s1 and s1g computers. The ST numbered products are the display
heads that function as the interface to the computers.

a) consult the manual
b) consult Raymarine (or a local Raymarine dealer)

I believe it is one of the old Autohelm units.

The manual is online in the "retired equipment" section of Raymarine's
customer service site, but there is no mention of part numbers for
sensors. There is a rudder angle sensor for sale on EBAY that looks
like it would probably work. They are all about the same I believe.

is a rudder angle sensor necessary for an autopilot? I thought the
heading of the boat would be sufficient.

There is no one sentence answer possible. Lots of boats steer to their
owners satisfaction without a rudder angle sensor. Most boats steer better
with a rudder sensor incorporated. Some boats can become absolutely unstable
and dangerous under autopilot control, and in these boats, rudder angle
input is absolutely necessary.
It's hard to go wrong with the sensor, and with many vessels (and
owners), a rudder angle indicator at helm stations is a great docking aid!

Just an note here....

Most of the Rudder Angle Sensers are just Linear Taper Pots, that drive
a Feedback Loop in AutoPilot Rate Control Circuit, BUT the Wood Freeman
RAS is very different, as it uses a Hall Effect Device, and is basically
the same device as the one in the Steering Compass. They both feed
OPAmps in the BrainBox. The Compass Senser drives the Course Feedback
Loop, and the RAS feeds the Rate Feedback Loop, and the Rudder Angle
Indicator Drive.

who cares what the rudder does, as long as the boat is going in the
right direction?

Particularly with a single engine boat, and sometime with twins, you
use the rudders to direct prop thrust during slow speed maneuvers.
Knowing in advance where the rudders are saves a bit of trial and
error with the wheel.
