The H23 rudder (at least mine) floats. If you uncleat the downhaul line it floats up to the horizontal position, sticking more or less straight back. That doesn't help when you pull it out with the trailer, of course. I don't think a spring to pull it would add much value. You don't want to leave it hanging that way as any wave action onto the transom will whack the rudder back and forth with some force. I leave mine all the way down in the slip and secure the tiller with a pair of 24 in shock cords. In fact, I'm not sure how high and how much out of the water you can even get the rudder due to the metal housing. Of course, use of the red lifting line should work to hold it up while hauling thetboat out of the water.
