The rudders are balanced, and large. The forces can get quite high, but with two rudders to steer with, the corrections are not large. There are also a lot of helm balance options with the rig and the rudders, especially if it is a schooner.
No idea of the torque or power required, although it is a one hand on the wheel steering job under most circumstances, so there is no reason why a similar sized autopilot to those used on a similar sized cat or tri would not do a similar job.

I have seen big 50+ tris fitted with cheap, small tiller pilots, which was possible due to them being very balanced. The rudders on the harry don't look balanced. what kind of torque are we talking about and how strong (how much electricity will it draw) does the pilot need to be?
