Why not just improve the lifting mechanisim on the present casette type T foil rudders? Personaly I like the idea of only having half the rudder, or less, down when coming in to or departing the beach. You will still have a lighter helm than with a kicked up rudder, which can be hard to steer in big wind and waves. And it would seem the casette type system would be lighter, less moving parts to break, etc.

Could someone who uses the present T foil rudders please post a close up picture of the headstock and the rudder in both the up and down possition, and tell us how it works? Thanks.
