My new to me Raymarine 1000 states a distance of 23.2 ins from tiller pin to cockpit socket,my old autohelm was 18 ins has anyone used the existing mounting or will I have
to drill more holes which I am reluctant to do?
 
Try the existing distance. You may find less turning one way. If it is a problem either trim the sails better to lose weather helm or drill new holes.

Get an extension for it. Details are in the manual.


Edit. thats rubbish isn't? You want to shorten it.:confused:

5" is a big difference. It'll have very little movement of its travel left when trying to turn to port (?)

The sensible thing to do is to try it ............... but accept that you will almost certainly have to fit a new mounting socket.
 
I've got 2 sockets, one for the old analogue autohelm (that still serves as a spare) and one for the newer Simrad TP10 that we currently use. I did try the TP10 in the old hole originally but the TP10 would bang into its stops much too soon.

+1 with Vic. (except the shortfall will be to starboard if conventionally located to starboard). At a rough guess, the unit's full travel is little more than 10 inches,so it'd hardly steer that way at all.

Which is turning the boat to port .........????
 
Sorry to hijack but i have been offered the same model for my 27 ft, 3 ton boat..the book of words say suitable for up to 30 foot..i know it will be working at the top end of its spec most of the time, but what do you think? should i go for it..its works great and it is very cheap.

If it's very cheap then yes, go for it. My TP10 won't steer the boat (very well) in the most boisterous conditions but then I want to be steering myself anyway. It's the boring bits that you want the tiller pilot for. Plus putting up/taking down sails etc.
28ft 3.8 tonnes.

The displacement figures quoted by Raymarine are a very broad guide IMO, much depends on the characteristics of the boat in terms of weight on the helm, rapidity of response etc.
A major difference between the 1000 and 2000 models is speed of response, the 2000 is much quicker.
I'd expect the 1000 to be fine for your boat for motoring and sailing in light conditions, esp. with the wind ahead of the beam.
If you buy it, at least it will be useful in those conditions, and as a possible spare.
Off the wind, on a lively broad reach, many autopilots can struggle with response speed.
 
Many thanks for all replies,Connected it to 12v supply and measured travel of ram only 1.5 inches travel in one direction so I will have to drill.

On a 31' Moody, the ST1000 is too light. The ST2000 is fine. But AIUI, it is displacement rather than length that is important; the Raymarine web pages certainly specify a displacement with an indicative length.

In France they told me that because I had used an extension (which they sold to me) it invalidated the warranty (which they didn't tell me when they sold it).

They also told me that I had allowed it to get wet.....

The quote for the repair exceeded the price new....

My A/H 2000 lasted warranty period (2 years) plus 2 months for a total boat utilisation time of 3 - 4 weeks.

Not a happy bunny....

That's ridiculous. All the more so as the extensions are recommended in their own manual.

TBH though, I've read many reports of the things having problems with water ingress. So I've made a snazzy glove that fits over my tiller pilot. I just hope that I've made sure that it has enough ventilation to prevent problems with condensation. Time will tell.
 
I have a 27 foot boat weighing about three tons as well. The ST1000 works well for me, it does struggle a bit downwind, but I gather that is fairly normal for an autohelm when swells start pushing the back end of a boat around. They are definitely happier when sailing uphill.
