I only have ai presume from the circular mounts to the beams that they are meant to kick back in a collision. if so, why go to the bother of making them able to dagger up as well? you could change the fore-aft CLR and/or draft for shoals by simply rotating one or both about the beams respectively.

They do not steer well when rotated as the axis of rotation becomes horizontal.
is there less ventilation if the top of the foil is completely submersed and only the shaft breaks through the water surface? that'd be nice.
There is much more resistance from the bare shaft. A fairing attached to the bottom bearing, but not the shaft will be an improvement.
rob: how do the rudders on sol2 work? same degrees of freedom as gardners: kick back, dagger up, and swivel to turn??
Same, but I am less sanguine about sailing in shallow water, so they will not lift up. "Daggering up" usually refers to the blade being lifted between two cheeks. On mine and Gardners, the shaft lifts. This makes the bearings a little more complex.
