Quote: had an old Autohelm 1000 with the red compass rose
Thats what mine is. It is very much shorter from mounting to tiller but its tail sticks out quite a bit more than the new ones do. Even that was supposed to be mounted 480mm from the tiller. The other common tiller pilot of that era was the Seafarer Mini Seacourse. I have no idea of its dimensions but it had a whole row of holes for the tiller pin rather than just the one as with Nautech/Raymarine or Navico/Simrad ones.
There is no point in looking for one of the old relics as the modern ones are much more technically advanced.
I think simonmaclellan's only solution is to fit an offset tiller pin, as Danny suggested, but it's going to have to be offset by around 150mm. That'll be a nuisance having something that size on the side of the tiller unles it can be made detachable.
