Antique autopilot
 
Lighted Panel.webp

While we're at it. What is this panel for? I never remember to investigate when I have another person on the boat to operate the switch.

I have 4 bilge pumps but I don't think that's it. Tank selection is by mechanical valves. 1978 46C.

I can make the different lights come on in various pairings with the 2 switches. of course not knowing what they are I don't leave them on long.
 
ah already found that one out , its the old engine diagnostics monitor alarm . its hooked up to a mouse in the engine room that rings you if he smells any smoke or feels hot.

wow really. I didnt see any sign of it anywhere else. figure i would have seen a switch or two at the helm.
 
That panel looks home-made to me, not like something that would have been on a '78 boat.

That green components could be a part of an autopilot system of that era as suggested - I see something that MIGHT be a servo-motor so perhaps it is an autopilot pump controller. The domed shape green thing MIGHT be the compass for an AP…

However, as you pointed out, one would expect switches/panel of some sort or at least an indication of where the control head was located at the helm. Wonder if that panel in the first pic is related…


Is this a test? Do you actually know what the components are? :)

Oops, sorry - I missed the part where you found that the panel was related to an alarm system. Sure looks cobbled to me - I don't know what year they changed but our '80 has the 12 point alarm system that actually looks like it was made by company that had machinery to do so! :)

A lot of he old pilots did not have a control head,just a push pull switch at the helm. Steer the boat to the course pull on the switch. Metal marine was like that. Most of the 1975-80's Hatts had them. Simple and worked well.
 
"A lot of he old pilots did not have a control head,just a push pull switch at the helm. "

I didn't realize that. Our '80 has a Raytheon Neco that has a control head with the heading control dials/switches, etc. I had assumed that that was typical of APs of that era.

That elec panel in the OPs pics still looks to me like something made in a garage as opposed to something that was originally on the boat. Did the old style alarms not have labels on anything?
 
Autopilot

Yeah, that's an old BenMar Compass unit. The red jeweled light on top was an indicator that the compass light was still burning. It's a marvel of ol' timey engineering. The magnetic compass within that binnacle would shine more or less light on photo-detectors generating a voltage telling a circuit board (usually up at the helm) to kick on a 12v motor driving a pump by belt either forward or backward as needed. It's awesome in its own way. The cable running out of the binnacle hooked to the rudders and provided a sort of negative feedback to the compass to keep the system from oscillating.

I'm in the process of changing ALL that stuff in our old Hatt (1968) over to a board that incorporates 3 gyroscopes, 3 accelerometers and a three-axis magnetometer. 15 bucks if you can believe that. Think about it - you cell phone has better technology as an afterthought. We are doing away with the compass, the feedback mechanism, and the guts of the control head. (keeping the box and interface buttons) with a board that would be blown away by a puff of wind. (below) We still need old pump and motor, so it's quite a marriage of technology.



I'll post the progress when we start testing and calibrating next Spring.

The alarm panel is original Hatt labels were silk screened or something like that that dissapeared in a couple years. Same panel was on a 76 46c I used to run.
 
Same alarm panel on our 1975 43DC. Standard Hatt equipment for that vintage.
 
"Standard Hatt equipment for that vintage"

Wow, I would have thought something better looking would have been on a Hatt. I had a late 60's 16' Glastron back in the day (1970) - lots of water skiing on Possum Kingdom) with better looking panels than that! :)

Thanks for the help. I would have never imagined it was factory either.

Don't know if I will go to the effort of replacing the cover plate but I will surely read a new one to see if I can figure the thing out.
 
Eric,

Definitely want to know the progress of you replacement project on Page 1! Cool idea...

(Couple of pics of new boat now home in my profile.)

Best,
DAN

You got it doc. You're at the top of the routing list. Most of this project is at the whim of my genius friend Dave, who is retired Navy and who is doing most of the work "just for kicks" It has been and will be quite a learning experience. For example, 2 weeks ago I couldn't even SPELL "Kalmann Filter" and today.... well now I can spell it. :-)

Saw the pics. The boat looks great!

Eric
 
I have searched and can't find a picture of a panel like the one I posted online anywhere. Can anyone tell me what was supposed to be printed on there? How to use it? What do the selector and toggle do? Thanks
 
This alarm panel was to monitor ER Fire, high bilge, engine temp and low oil pressure with sensors on each engine or engine room. The switch in the lower left turns it off and on. The rotary selector switch was used to test each circuit. When a circuit was tested or an alarm event occurs the light will come on and a bell, located under the helm panel, will sound. A simple test is to turn on the panel with the engines not running. The low oil pressure alarm should sound. Like the panel above I could not read the printed labels, but I traced it out and have mine labeled with label-gun stickers. I do not recall the order, but I will go to the boat in the morning and photograph my panel. It has been a life-safer on at least two occasions. It will about give you a heart attack if you have a bell like mine and forget to turn off the panel before shutting down.
