Re: Autopilots on PSCs

If you have a Monitor you could try this.

As has been described by others, we hooked up an ST1000 tiller pilot (actually an Autohelm 800 initially) to our Monitor wind vane. This solution works while sailing or motoring. Hans at Scanmar says the prop wash while motoring is hard on the Monitor but we haven't noticed any problems.

We upgraded our installation two years ago to include the Raymarine S100 remote control so we can tweak the course without having to push the buttons on the ST1000. We also put a three-bladed prop on which reduces the prop turbulence on the Monitor.

If you are interested I could send some pics or more info.

Oh, sorry! Yes, I was referring to the owner of the 31.
Been a bit muddled with family/hospital stuff and two boats!
Thanks, Jim

Did you mean 'DGriffith' instead of MC1? I didn't have to do any bulkhead modifications on my PSC '34.

The WH Autopilot I installed on Crazy Fish has an stout arm that mounts/clamps to the rudder post below the quadrant. The end of this is attached hydraulic actuator that is mounted starboard bulkhead which I beefed up using a piece of 2x6 and fiberglass.

Currently what WH calls the RAT which provides the feedback on the rudder position which is lightweight device is attached to the quadrant. When I convert the boat from wheel to tiller I will have to come up with something else.

I assume from your post that on your boat there is a fiberglass column surrounding the rudder post thru the engine/below decks compartment and
that you will need to cut thru it to gain access. Would seem that the bearings
for the rudder post would be located where the post comes out the deck and
in the hull so completely removing his fiberglass column would be fine.

Might call Thumper at the factory to see what they would do if converting the boat from tiller to wheel or just adding a below decks autopilot to a boat configured as yours. He has been pretty helpful working with me on the wheel to tiller conversion.

Also couldn't be happier with the WH Autopilot that I installed ~1998. The unit just continues to work. My first issue occured a couple of months ago when the remote control stopped working. There was some corrosion
around the buttons, etc. I sent it in and for $160 they overhauled and ship it back to me.

Thanking you all,

Keep reading how access is a squeeze, then see this an looks easy.

I wish to put a below deck auto pilot the the afore mentioned. Any experience or advice (and photo) much appreciated
The pictures are of C34 but access on the newer 37s (at least from 1989 on) is thru an access hatch in the forward part of cockpit.

I installed a WH belowdecks autopilot on Crazy Fish and I ended up spending quite a bit of time behind the engine but there seemed to be plenty of access.

The hydraulic ram installed on the starboard bulkhead and the bulkhead needed to be reinforced to support the forces involved. Reinforcement was done with a piece of mahogany, West System epoxy and a layer or two of fiberglass mat.

Autopilot was installed with in 97 and I was very happy with the support from WH and the autopilot itself. Largely made up of robust off-the-shelf components easily replaced without buying from WH if needed. That said I have never had to replace any component.

I have, but I have a 2-blade prop and kept the speed
down to 5 knots to minimize prop wash. And assuming
its light wind conditions, it helps alot to have the light-
air wind vane.

I'm always amazed at how often we motor sail. We prefer to sail using the Monitor but weather and time tend to conspire against us...
