For clarification, the Stealth T foils are strictly for anti-pitchpole purposes. They do little for the stern wave--they're just too deep. When I sailed with the T-foils they did prove to be very potent at preventing nose diving. But they were also very unforgiving to any surface grass, fishing line, or as we encountered, rope from a crab pot. (At least we had the second rudder to steer us home.)

Off the subject...a really nice aspect of the Stealth rudders is the cassette up/down design. This allows you to push the rudders only part way down in light air or shallow water. Of course, there's not way to do a kick up mechanism with the T foils. But a standard rudder that had both cassette up/down movement and a kick-up mechanism would be very handy and safe. I believe some of the new Farrier trimarans have such a rudder.
