Hi guys, I just purchased a tiller pilot, pics and tips are more than welcome, I would like to know what the best way to install it! Thanks

The most important thing is to feed it via heavy duty wire. Resistance in small core will drop the voltage and they love 12,9volts
Check out previous discussions . I made a wood removable bracket that clamped onto the horse
worked well ..

Have a look at my installation on Klipspringer

I did this to reduce the electrical interference from the engine.
I echo Ron's comment about electrical supply. On Klipspringer I routed the cable from the battery to a waterproof box with switch and fuse quite separate from the distribution box. This made a significant reduction in the cable length and reduced the connections in the circuit - all of which help to maintain voltage at the pilot.

The pin of my ST1000 fits into a small metal collar drilled into the top edge of the coaming. Very neat and solid. I don't know whether the collar comes with the tiller pilot or not. Agree with the comments about voltage.

You will need an extension if you put it on the coaming.

I don't have an extension. I'll try and take a photo tomorrow

I don't think I do, anyway!

Collar comes with unit. Extension is 1" if on cooming, if my memory serves me right. Instructions tell you how to work it out.

You will need a 102mm extension £24 from force 4 ...
A hole in the coming will need reinforcing from under neath with epoxy. and a fillet of wood.

Since I hardly use the engine, can I use the same electrical cables which are already in place towards the back?. I would remove the old socket next to the mains socket.

I would directly wire, via a waterproof socket .with heavy tinned cable to the battery direct.
Old cable will be internally corroded sling it . Not an expensive job ..

Ive just looked at my vid. long sail untidy boat!
Norms right . extension not fitted as raymarine seems longer than my autohelm1000
That does need a 4in extension.if fitted on the combing.
Sorry to confuse the issue.
Just measure total extension half it. put tiller midships offer up unit . check alignment.

Auto helm shorter than its reincarnation as the Raymarine ST range so needs more extension. I have found that the cooming being very narrow is v strong and does not need the strengthening you suggest Ron.

All boats have probably been rewired and/or added to over the years. Use new wiring and sealed box as I and Ron have suggested.

I've added some photos to the group. My raymarine fits to the coaming and has no extension. It works fine - not having an extension limits how far the tiller will go to port (see photo) but in practice I don't find this an issue. I have no problems with interference from the outboard. I find that the pilot works well when the wind is forward of the beam, but it struggles on a broad reach in a lumpy sea - it can't anticipate the swell and responds too slowly, so is constantly over-compensating. The ST2000 is quite a bit faster I presume. The unit only takes a couple of amps under load, so I don't think you need to go overboard on the wiring, but it is sensitive to the state of the battery. You will know you have a problem when it beeps and cuts out at an awkward moment. This begs the question of how you're planning to keep your batteries up on your race...

One of us has to be right!
Norm says no extension needed.
I know its needed with the autohelm 1000. Not shure on the tillerpilot.
cejenika says it works ok without but should have an extension.!
I fitted an insert on one of mine. but had to beef up the combing as it was too thin,, maybe
the layup was poor on that bit?
I have a friend who trouble shoots electrical probs on super yachts ,, He sails a Seamaster 23
(we call it Testbed) He told me most problems with any autohelm is small wiring.

Emily, hole on top of coaming and needed extension on both the TP10 and the ST1000. BUT the same extension fits both makes. Voltage drop also got me until I wired it direct. Then decent connectors. Don't think it is the amps that get you think it is the voltage drop when they kick in at 2-3 amps that seems to throw them into a bit of a wobbler. Do know they let you know when the battery is getting low by stopping first!

I just drilled through top of coaming, no reinforcing needed as thick there!

Plus they have to learn so you are supposed to do slow circuits to set flux gate. All I know is that they do get better as they do seem to settle down. Farmer John says to take a spares kit on a long trip as his stripped gears half way across Biscay.

Agree on cable, I think I ran a new 13A cable to a fuse box in the locker and then use Bulgin Buccaneer waterproof connectors.

Here is the arrangement we had on Aeolus several years ago when we had her this was a
Raymarine ST1000 fitted into a wooden block attached to the coming not requiring any form of adaptation, and worked fine.

A tip when sailing using the autopilot is to ease the main and let the boat drive on the jib. The less load on the tiller the better.

Good question!! I haven't tought about that yet, I assumed that with my 2 (1 yr. old) batteries I would be able to survive the 30 hours race, which should be a max to get to Lowestoft. Last year some did it in 23 Hours.
Fast Lex 5 years ago
Checked the batteries, I have a 105 AH ( 20hrs) for the engine and a 75AH (20hrs) for the cabin accessories & lights. So I decided to attach the plotter/AIS and VHF to the engine battery. The ST2000 will also be on this battery.

Since the ST2000 is one of the major users of amperage if you are wiring them separately I would keep that away from the engine start battery. I have wired my 2 batteries to be entirely interchangeable through a change over switch. I then use one of the batteries and leave the other unused for engine start etc. If the first battery goes low on voltage I would not switch to the other unless I new I had only short distance to go. I would normally do something about charging the first or limiting its use. If you have a fishfinder or chartplotter one of the options in the menu is to display and alarm battery voltage. This can be a useful feature to use. If you wire the batteries completely separately and something happens to one of them you are then faced with a problem of how to connect the ok battery. With the changover switch if one battery fails it is easy to go to the second battery and this could be important in certain situations.

This is true, however usually I do not sail more then 10 hrs per day without the next charging session in a harbour. I have the batteries linked to each other but with a diode block in between, so if my cabin battery goes low it will not effect the engine battery. I also have a volt meter on both batteries. www.flickr.com/photos/achilles24_fast_lex/8151505398/
Theoretically the ST2000 uses between 0.5 & 1.5 A per hour, If I would use the autopilot for 30 hrs in a row I would still have +/- 60A left on my engine battery to use. Anyway I think to be on the safe side towards Lowestoft will take a 3rd battery with me, just in case.

I'd agree with Norman but add that you should consider using the smaller battery for the engine starting - although the starter current is high, it's only for a few seconds and the loss in terms of Amp hours is insignificant and usually replaced by the alternator before you've got out of the harbour/marina. Then use the change-over switch to top up the big battery until you're under sail.
The one thing you don't want to do with most modern engines is to run the starter battery flat. The next worst things to do that are the VHF and the chartplotter display then, depending on model, the autopilot.
You might find it instructive to list all your electrical usage on a spread sheet for the expected 30 hours of the race and add it up. For your total 180 amp hrs nominal installed battery capacity, you must aim to keep the actual consumption down below 90 (and then get charging ASAP). Your batteries can't be too big - only too heavy!

I agree with you and Norman, I wll add up all electrical equipment in an excel doc. & see the outcome! Thanks !
Fast Lex Posted 5 years ago. Edited by Fast Lex (member) 5 years ago
So guys , I did my maths & this is the outcome : AIS=0.125A, VHF=0.5A, Splitter=0.02A, Plotter=0.53A this brings me to a total of 1.2A, if I calculate 60% of the battery capacity, this would give me +/- 40 hrs of battery power. So all this will be installed in the cabin battery leaving the auto pilot on the motor battery which is a new one of 105A. (Feel free to advice).

I stick to my advice as above. I just don't see why you wouldn't use a changeover switch. Your calculations show that you are close to capability of battery. Given that Batteries are seldom fully charged even if you think they are and you may take longer than you think, then I would certainly have much greater capacity and redundancy, or be prepared to use the engine frequently to charge the battery. Can you start the engine by hand?
Fast Lex 5 years ago
You're right I forgot to mention the change over switch, I will also install this so just in case the cabin battery brakes down then I can switch over onto the engine battery. The engine can also be started by hand .

Now we've got that sorted - don't forget to enjoy the race!
Good luck with it.
