    Parameters: light boat, 6000 Lbs, 28 FT in lenght with a single inboard. Current approximate max speed 28 Knts. What speed advantage, if any, could be gained by moving the rudder from behind the prop and using a twin rudder design flanking the prop on either side?

    Thanks. I asked because I saw an early high performance chris, inboard with twin rudders. It was marketed as high performance for the time. Thinking that the rudder is in the "thrust" that the drag would be more there then out of this wash. I am still hoping that someone has tried personnally and has some hard data. Again thanks for the thoughts :)

    Can a rudder produce a strong turning force on a sea kayak; other wave-fighting recommendations?
