    This is a point I neglected in my comparison of the J36 and the Cal
    2-30. The prop is below the deepest part of the hull on the J, as well
    as being forward. However, the hull bottom is as close to the prop as
    it can be. Aubrey's suggestion could be tested with a finless submarine
    :-).
    
    Another related matter. Does anyone know if a single-screw tug with a
    Kort nozzle surrounding the prop has any walk?
