    In this connection, I cannot resist telling the story which
    is somewhat away from the main topic of this list.
    
    In 1889, they discussed a formula for measuring the racing yachts.
    
    "One of the Nestors of the New York yachting, a man whose
    expert knowledge of sand-bagger yachts entitled him to speak
    with authority and to be heard with attention, was called on for his
    opinions. His remarks were brief and very much to the point:
    "You want a plain and simple rule, with no hyeroglyphics and
    no plus in it. Who knows what plus is? I don't know what plus is.
    You take the length overall and the length on the waterline, add them
    together and divide by two, and you have a plain simple rule
    with no plus in it".
    
    (C. A. Marchaj, Seaworthiness. London 1996, p. 41).
    
    Alex.
