T-foil rudders are promising.

I'm a total convert. Either upwind or definitely downwind where I sail (Bristol Channel, Irish sea or Atlantic Ocean dependent on wind direction) T foils are the equivalent of the "Star Ship Enterprise" (work that out for yourself) <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
