DougThere is no consensus but a HP balances well with trailing rudder down and leading rudder up.
With bigger HPs, where rudder is not easily lifted, there is merit in smaller rudders either end and a centre cambered dagger board that can be raised off the wind.
The Dutch HP now has horizontal shaft through the hull and a large bearing housing for the rudder shaft. This is primarily for collision protection but they have found that the rudders can be rotated up to the water level by the drag force once moving with some speed. They have a brake on the rotation that allows locking in any position.
There is plenty of inspiration for rotating lee boards in Holland; vast area of shallow semi-protected water.

Hi,
Browsing back through some old messages here.
See here, that it looks like Herb is trying to rotate the rudder when doing a shunt.
How can I explain this?
So, the aft rudder you are using before the shunt gets lifted up during the shunt since you are not going to use it on the new "tack?".
It doesn't have to rotate 180 when you pull it up, it just comes up and stays out of the way.
Just wondering, because Herb says that the hinge was breaking.
I never used 2 rudders down.
Incidentally.
There is divided camps on using one or two rudders still?
Any consensus?
I finally got mine going great with one down, so haven't worried about it much, but I hear also good success (and some bad) stories with 2.
Simplest with 1?
Better leeway prevention with 2?
Doug
