Different principle, in the case of the rudder, the winglets are like a
cavitation plate on an outboard, but in addition to stopping cavitation,
they also add waterline to the stern of the transom hung rudder. I just made
a kick up rig for my rudder and relocated it to the transom, I will be
putting a top plate on it when I build a better rudder.
