Perhaps a partial skeg with the screw in an aperture is the best compromise. The rudder would be supported much lower and consequently stronger than a spade rudder. It is less wetted area than a full skeg giving performance and the rudder couldo be shaped so that some of it extends forward of the hinge allowing it to be more balanced. I would be particularly good if the portion extending below the skeg was designed to be sacrificial so that, in the event of a major blow, it would just break off leaving the portion above the skeg to steer with. The screw in the aperture would be well protected.
