We have a Hydravane on the new girl although to date we havn't used it in anger. Reports however from previous owners are all positive. That thing has steered her from Sweden to Australia via Panama plus two tours of duty around the islands of Oceania and thus far without any failures.
It is quite capable of acting as emergency tiller. Ours also has an attachment for a tiller pilot giving a back up auto pilot if required.
I've also heard they can be mounted off centre without effecting performance. I wish ours was though I doubt we'll move it. I'm not all that keen on drilling new holes in the transom.
