I'd be interested to know if anyone operates an autohelm or tillerpilot on an 8.5 multihull. I'm thinking that it would be useful for sail changes and deck management if you're shorthanded or sailing with non-sailors. I imagine actually sailing with one would be quite inefficient relative to having a capable human on the tiller.
I also realise that there are certain conditions where you wouldn't want to leave the steering responsibilities up to a robot which can't feel the wind gusts.
If anyone has any experience with one I'd be keen to hear about it.
