I think the answer to this is no, the only way I can see is that you can fit them to kick up rudders is if you pin them down before you go out, so you must have the boat in deep enough water to be able to have the rudders fully down before you get on. I doubt you will be able to get enough rudder in the water to steer with the T completely clear of the water.

I can see no way that you will be able to steer the boat with these on unless the rudder is fully down.

If you do manage to make it work, you will have to pin them down, the loads get quite high when they are working hard, it would be a disaster if the rudders kicked up just when you were flat out and the only thing stopping you from pitchpoling is the foils.
