    Did you notice the difference in angle of the leading edge of the rudder?
    And the difference in the prop placement in the diagram?
    Even the hull is different. How will you "modernize" all those
    features to match your updated rudder idea?

    Along with a slew of other reasons, don't modify the shape of the rudder.
