Hi Rudolf,
If the leeboard worked dead centre of the lw side, then I would think it wouldn't need any handling except to lift or tilt it when water got shallow. Even if it needed a bit of tilting to get it right, if there were set stops, it could be easily controlled from the cockpit with the right pulleys.

I have wracked my brains and can't really see any reason not to go that way. It could be trialled by lashing the spare rudder to the leeside right at the centre. It would certainly be consistent with the history of boats in the region. It would fit with my understanding of the forces though my understanding needs to be taken with a grain of salt: these interactions between air and water have fooled me more than once.
